Cheapest International Flights from Mumbai in 2026 — Complete Route Guide

1,411 flights leave Mumbai every week flying to destinations worldwide. That number alone should tell you something: Mumbai is one of the most connected international departure points in Asia, with 59 airlines serving routes across the Middle East, Southeast Asia, Europe, North America, Africa, and beyond. The competition between carriers is fierce. The price variation between the right and wrong month is enormous. And the gap between what most Indian travellers pay on MakeMyTrip and what someone who knows this route actually pays — on the same flight — can run to ₹10,000–₹15,000 on a single return ticket.

This guide does what no aggregator will: it lays out the cheapest return fares from Mumbai across six major international routes, month by month, in rupees. Dubai from ₹24,000 in September. Bangkok from ₹23,000 in August. Singapore from ₹22,000 in July. London from ₹84,000 in June. Toronto from ₹88,000 in May. And a Sharjah option that undercuts every Dubai fare by ₹4,000–₹8,000 every single week of the year — a detail that Air Arabia operates 14 flights per week to take advantage of, and that most Indian travellers have never heard of.

Before anything else, one thing to sort out: Mumbai's international flights depart exclusively from Terminal 2 (T2) at Chhatrapati Shivaji Maharaj International Airport. Terminal 1 is domestic only. If your cab drops you at T1 — and this happens to hundreds of travellers every week because apps default to the wrong drop point — you're looking at a 30-minute inter-terminal shuttle, a recheck of your baggage eligibility, and an elevated blood pressure reading. Set your cab destination to "CSMIA T2 International Departures" before you leave home.

We compared fares on FlyFlick with major Indian booking platforms — and found savings of ₹1,000–₹2,500 on most international routes. Search below and compare yourself before booking anywhere else.

Booking in USD through FlyFlick? No GST applies on international flights booked via foreign platforms — you're not paying Indian service tax here. To avoid your bank's forex markup, use a zero-forex card like Niyo or Scapia. Note: a 5% TCS applies on foreign currency payments but is fully refundable when you file your ITR.

Terminal 2 at CSMIA Mumbai houses the Jaya He Museum — 5,500 artworks by over 100 Indian artists and 1,000 artisans spread across the terminal's walls, making it the world's largest airport art installation. Arrive 30 minutes early and actually look up.

Cheapest International Flight Prices from Mumbai — All Routes 2026

The table below consolidates verified economy return fares from Mumbai (BOM) across six major international routes, current as of April 2026. These are real prices for travellers booking 6–10 weeks out — not theoretical minimums.

All prices are approximate return economy fares per person. Currency conversion at ₹94 = $1 USD. Prices fluctuate daily — use FlyFlick's search to verify live fares before booking.

The Sharjah row in that table is the one most Indian travellers have never seen before. It's not a typo. Sharjah International Airport (SHJ) is 20 km from central Dubai, serves as Air Arabia's hub, and handles multiple nonstop flights from Mumbai every day. The return fare difference between flying BOM→SHJ and BOM→DXB on equivalent dates averages ₹4,000–₹8,000. On a return trip for two people, that's ₹8,000–₹16,000 saved without changing a single thing about your Dubai itinerary. We covered this in detail in our Mumbai to Dubai flights guide — the strategy applies equally to every Mumbai–Dubai search you run.

Mumbai to Dubai — Cheapest Months and Best Airlines in 2026

Dubai is the most-booked international destination from Mumbai — it consistently ranks as the top international route from BOM by passenger volume across all booking platforms. That popularity drives competition, which keeps fares competitive — but only if you fly in the right month.

September is the single cheapest month for Mumbai–Dubai return flights in 2026, with nonstop fares on budget carriers running ₹20,000–₹26,000. July and August are close behind. The reason: Dubai's summer heat (43–46°C) suppresses Western leisure demand while keeping the city fully operational. Indian travellers who aren't deterred by heat — and most aren't — have access to a world-class city at prices that would be unrecognisable to anyone booking a December trip.

Expedia's live data shows Mumbai–Dubai return fares as low as $228 (₹21,432) on IndiGo for a Tuesday July departure. On Air Arabia into Sharjah in September, that figure drops further to ₹18,000–₹20,000. December, by contrast, sees the same route priced at ₹55,000–₹70,000 on budget carriers — more than triple the July low.

For airline choice on this route, the calculus is straightforward: Air Arabia via Sharjah for the cheapest all-in fare with a bag; Air India Express for the best budget-plus-baggage-included combo; Emirates for the full-service experience with 30 kg checked allowance. IndiGo's headline fares look competitive until you add a checked bag — ₹2,500–₹3,500 per leg on international routes — at which point it stops being the cheapest option on most date combinations.

September is the cheapest month to fly Mumbai–Dubai — fares on budget carriers drop to ₹20,000–₹26,000 return, roughly 40% below the December peak, for a city that's fully operational 12 months a year.

Mumbai to Bangkok — When January and August Beat Every Other Month

Bangkok is the second most popular international route from Mumbai, and it has a pricing pattern that differs meaningfully from the Dubai route. Cheapflights data confirms January as the cheapest month for Mumbai–Bangkok, with average round-trip fares around ₹12,515 one-way — translating to approximately ₹23,000–₹25,000 on competitive return tickets. August is the second cheapest window per Skyscanner's calendar data, with Saturday, August 22, 2026 flagged as currently the cheapest single departure date on this route.

The flight from Mumbai to Bangkok is approximately 4 hours 23 minutes nonstop — shorter than Delhi to Bangkok by about 15 minutes, because Mumbai sits further south. Over 175 scheduled flights operate daily on the Mumbai–Bangkok route. That frequency means competitive pricing is structurally baked in — but the seasonal swing is still dramatic: December return fares hit ₹42,000–₹55,000 on the same carriers that charge ₹23,000 in August.

For Indian travellers specifically, January has an additional advantage: it sits neatly between the Diwali/New Year spike (which peaks in December) and the Holi surge (March). It's the quietest Indian travel month, which is exactly why fares are cheapest. If your schedule allows January travel, Mumbai–Bangkok is one of the best-value international routes from India at that time.

Cleartrip notes that mixing carriers — booking the outbound and return legs on separate airlines — sometimes saves ₹2,000–₹6,000 on this route. A Thai Lion Air outbound from Mumbai in August at ₹11,000 combined with an Air India Express return at ₹12,000 frequently undercuts any single-carrier round-trip. Always compare the split-booking total before confirming a round-trip on one airline.

For full details on visa requirements, airport choices at the Bangkok end (BKK vs DMK), and step-by-step booking strategy for this route from Delhi, our Delhi to Bangkok guide covers the full picture — the BKK vs DMK airport angle applies equally to Mumbai arrivals.

Mumbai to Singapore — July Is the Window Nobody Uses

Singapore from Mumbai is a 4 hour 30 minute nonstop flight — one of the shortest routes to a tier-one international city from India. Over 200 daily flights operate on the Mumbai–Singapore route, making it among the most frequency-heavy short-haul international options from BOM. July is the cheapest month — return fares on nonstop Air India and IndiGo services drop to ₹22,000–₹28,000. August is close behind.

The same structural dynamic that makes July cheap for Bangkok applies here: Singapore's monsoon peaks in November–December, not July. July has afternoon rain showers — 2–3 hours — that clear quickly. The city is fully operational. Gardens by the Bay runs its nightly light show regardless of the month. And the hawker centres, which are one of the genuine wonders of the food world, are open 365 days a year.

One thing to know before booking: Singapore has no visa on arrival for Indian passport holders. The visa costs ₹3,100 total (₹2,100 official fee + ₹1,000 agent service charge, updated January 1, 2026) and takes 3–5 working days to process. Apply through an authorised agent at least 2 weeks before travel. This is covered in full in our Delhi to Singapore flights guide — identical process and costs for Mumbai departures.

For airline comparison: Air India offers 23 kg checked baggage included on Singapore routes; IndiGo's Singapore base fare does not. Once you add a 20 kg bag to IndiGo's return, the all-in total frequently equals or exceeds Air India. Singapore Airlines is the premium option — 30 kg baggage, best on-time record on this route, noticeably superior cabin — at ₹24,000–₹38,000 return depending on the month.

Changi Airport's Jewel — a five-storey indoor waterfall and forest inside the terminal — is accessible to all passengers on a 3-hour transit. If your BOM–SIN layover at Changi goes long, it's worth walking through.

Mumbai to London — June Is the Cheapest Month and Air India Still Wins

The Mumbai–London route has the widest fare spread of any international route from BOM — between June and December, the same economy return ticket can differ by ₹46,000 on Air India. KAYAK data shows Mumbai–London one-way from ₹75,968 and return from ₹84,052 as representative averages — June sees the lower end of that range, December the upper.

A nonstop Mumbai–London flight covers approximately 7,195 km in about 9 hours 35 minutes. Nonstop carriers on this route include Air India, British Airways, and Virgin Atlantic. As we covered in full in our Delhi to London guide, Air India consistently undercuts British Airways by ₹25,000–₹40,000 on return fares while offering the same nonstop journey time — the analysis is identical for Mumbai departures. British Airways from Mumbai is priced at ₹1,00,000–₹1,20,000 return on most months; Air India on the same dates runs ₹84,000–₹95,000 in June, its cheapest window.

The UK eVisa process remains unchanged for Mumbai passport applicants: ₹13,500 (£127) standard fee, 15 working days processing after your biometric appointment at VFS Global (offices in Mumbai at Ballard Estate). From February 25, 2026, UK visas are digital-only — no physical sticker in your passport. Apply at least 6 weeks before travel and create your UKVI online account immediately after approval.

Mumbai to Toronto and New York — When to Fly and What It Actually Costs

Long-haul North America routes from Mumbai are the most price-volatile international segments from BOM. May is the cheapest month for Toronto return fares — ₹88,000–₹1,00,000 on Air India via London, or ₹92,000–₹1,10,000 nonstop on Air India's new direct Delhi–Toronto service (Mumbai travellers typically connect). December hits ₹1,30,000–₹1,50,000 on the same carriers.

Yatra shows Mumbai–Toronto return fares from ₹40,271 from Bangalore on comparable dates — Mumbai fares run similarly in May's cheapest window. Air India is the primary carrier for Mumbai–Canada routes; Emirates via Dubai adds 4–6 hours of travel but sometimes prices ₹5,000–₹10,000 below Air India in shoulder months. On a 14–16 hour total journey, that saving is rarely worth the additional travel time.

New York from Mumbai runs similarly — Air India nonstop from ₹95,000–₹1,10,000 in May, climbing to ₹1,40,000+ in December. Qatar Airways and Emirates via their Gulf hubs can price ₹8,000–₹15,000 lower on some dates but add 4–8 hours of layover time depending on the connection.

June is the cheapest month to fly Mumbai–London — Air India's nonstop 9h 35m service prices at ₹84,000–₹95,000 return, compared to British Airways' ₹1,00,000–₹1,20,000 for the identical journey time.

Indian Holiday Dates That Spike All Mumbai International Fares in 2026

No aggregator covers this. Every OTA shows you prices — none of them explain why the same flight costs ₹15,000 more on a different week in the same month. These are the precise windows when all international fares from Mumbai spike simultaneously:

March 25 (Holi) — ±7 days (approximately March 20–April 1): Indian outbound travel demand spikes across all short-haul routes. Dubai, Bangkok, and Singapore fares jump ₹4,000–₹8,000 in this window. Book outside it.

April 13–16 (Indian school summer holidays begin, overlapping Songkran Thailand): Combined Indian school holiday demand and Songkran festival inbound demand to Thailand pushes Mumbai–Bangkok fares up ₹6,000–₹10,000. This window catches more Indian travellers off guard than any other annual spike.

October (Navratri + Dussehra + Diwali — approximately October 2–22, 2026): Three consecutive festivals create the biggest Indian outbound travel surge of the year. Every international route from Mumbai sees 25–50% price increases during this three-week period. A Mumbai–Dubai return that costs ₹24,000 in September costs ₹35,000–₹42,000 in the first week of October.

December 20 – January 5: Peak of the year across every route. Book 90+ days out if travel is unavoidable.

How to Book the Cheapest International Flight from Mumbai — Step by Step

Step 1 — Fix your month before your destination. The single most effective price lever is timing. A week's flexibility in the right direction — from late September to late October, or from December to June — saves more than any airline loyalty discount or coupon code on any route from Mumbai.

Step 2 — Search Sharjah alongside Dubai every time. Booking 63 days in advance of your planned departure date is, on average, the best time to get cheap flights from Mumbai, according to Cheapflights. But beyond advance booking, always run BOM→SHJ parallel to BOM→DXB before confirming any Dubai trip. The Sharjah-Dubai taxi adds ₹500 to your trip and removes ₹4,000–₹8,000 from your ticket price.

Step 3 — Calculate baggage-inclusive totals. IndiGo and SpiceJet consistently show the lowest headline fares from Mumbai on short-haul international routes. Both charge ₹2,500–₹3,500 per leg for a 20 kg checked bag. Before calling either airline cheaper than Air India (23 kg included) or Air India Express (15 kg included), add the round-trip baggage cost. On most routes and most date combinations, the budget carrier stops being cheaper the moment you check a bag.

Step 4 — Book outbound and return separately. Open two search tabs. Run BOM→destination in one and destination→BOM in the other. Mix carriers. Mixing carriers can save ₹2,000–₹6,000 on return fares compared to single-carrier round-trips. An Air Arabia outbound to Sharjah at ₹9,500 combined with an Air India return from Dubai at ₹11,000 frequently undercuts any round-trip package from either airline.

Step 5 — Book on Sunday or Tuesday. Sunday is one of the best days to book for cheap flights from Mumbai — tickets reserved on a Sunday cost between 6% and 13% less than those reserved on a Friday, according to ARC data. Midweek bookings (Tuesday–Thursday) additionally trigger rotating bank cashback offers on Indian OTAs. HDFC, Axis, and ICICI regularly run 8–10% international flight discounts (capped at ₹1,000–₹1,500) most reliably on Tuesday and Wednesday searches. On a ₹26,000 ticket, that's a guaranteed ₹1,200–₹1,500 back.

Step 6 — Sort insurance, delay cover, and eSIM before confirming. Before clicking pay on any international flight from Mumbai, get VisitorsCoverage locked in — medical coverage up to $1,000,000 for every destination in this guide. Middle East and Southeast Asian hospitals operate at international private pricing; Europe and North America are significantly more expensive still. For a budget secondary option, EKTA covers basic international travel insurance from $0.99/day at ektatraveling.com.

For flight delay protection on any international route from Mumbai, Compensair covers up to €600 for delays and cancellations — file from your phone, no upfront cost, no fee if unsuccessful. For eSIM: Saily covers Dubai, Bangkok, Singapore, London, Toronto, and 150+ countries from $1.99/day with 5G — activate before boarding at CSMIA T2. For multi-destination trips or longer stays covering multiple countries, Yesim offers unlimited multi-country data on one plan. For remote or patchy-signal destinations beyond the cities, Drimsim covers off-grid coverage across mountain and rural areas.

Booking in USD through FlyFlick? No GST applies on international flights booked via foreign platforms — you're not paying Indian service tax here. To avoid your bank's forex markup, use a zero-forex card like Niyo or Scapia. Note: a 5% TCS applies on foreign currency payments but is fully refundable when you file your ITR.

CSMIA T2's international departure hall has a Regus Express business centre in the arrivals area and a Starbucks airside — but the real reason to arrive early is the 5,500-piece Jaya He Museum that runs the length of the terminal walls.

Bottom Line

Mumbai flies to over 56 international destinations in 2026. The route network is vast enough that the cheapest international trip from BOM looks different depending entirely on your month and your flexibility about which airport you land at. Dubai from ₹19,000 via Sharjah is the single cheapest option most weeks of the year. Bangkok from ₹23,000 in August is the best value for a week's trip to Southeast Asia. Singapore from ₹22,000 in July is five hours and a world away. London from ₹84,000 in June on Air India nonstop is the most underrated long-haul deal from BOM — compared to British Airways at ₹1,00,000+ for the same flight time.

The travellers paying double on these routes aren't unlucky. They're searching on a Friday in the wrong month, adding a bag after comparing headline fares, and booking into DXB without checking SHJ. That's the entire explanation. The fixes cost nothing except a second search tab and a look at your bank's cashback offer.

Book smart. Fly cheaper.
