Thai Lion Air offers one-way nonstop Mumbai to Bangkok flights from $84 (₹7,896) on its cheapest June and August dates. That number is not a misprint, a flash sale you missed, or a one-seat inventory trick. It's Thai Lion Air's standard base fare on select dates in the cheapest booking windows — and it flies into Don Mueang Airport (DMK), not Suvarnabhumi (BKK), which is why most Indian travellers searching on MakeMyTrip have never seen it.
Two of those fares — outbound and return, booked separately on the same carrier or mixed with Thai Vietjet Air — puts your Mumbai–Bangkok round-trip in the ₹12,000–₹16,000 range on the right dates. That's less than a Delhi–Goa ticket during peak holiday season. For a flight that takes 4 hours and 23 minutes and lands you in one of Asia's most rewarding cities.
The reason most Indian travellers don't know about Thai Lion Air's Mumbai–Bangkok service is simple: it flies into DMK, not BKK. When you type "Mumbai to Bangkok" on MakeMyTrip or Goibibo, the default search shows Suvarnabhumi (BKK) results. Thai Lion Air's Don Mueang fares sit in a separate search unless you manually switch the destination airport code — and most travellers never do. This guide is specifically about that gap. By the time you finish reading it, you'll know which airport to search, which airline to pick, why Indian passport holders don't need a visa at all, and how to construct a return booking that comes as close to ₹12,000 as the 2026 fare market allows.
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.

Wat Arun sits on the western bank of the Chao Phraya River — a 30-minute Grab from Don Mueang Airport (DMK) costs approximately ₹280 (120 Thai Baht), making it one of the most affordable iconic arrival experiences from any international flight from India.
Why Thai Lion Air Is the Airline Indian Travellers Keep Missing
Five airlines fly nonstop from Mumbai to Bangkok in 2026. Most Indian travellers book three of them — Air India, IndiGo, or Thai Airways. They miss the other two because of a search interface problem that costs them ₹6,000–₹10,000 on every return ticket.
Thai Lion Air operates 5 nonstop flights per week from Mumbai (BOM) to Bangkok's Don Mueang Airport (DMK), while Thai Vietjet Air operates 4 nonstop weekly flights into Suvarnabhumi (BKK). Both are ultra-low-cost carriers on a route dominated by full-service and mid-tier airlines, and both price significantly below the IndiGo and Air India fares that appear first on Indian OTA searches.
Here's the critical detail that no Indian editorial has covered: Thai Lion Air provides 20 kg free checked baggage on its Bangkok–Mumbai route — included in the base fare, not as an add-on. This changes the entire cost comparison. IndiGo's base fare from Mumbai to Bangkok looks ₹3,000–₹5,000 cheaper on MakeMyTrip — until you add a 20 kg checked bag, which costs ₹2,500–₹3,500 per leg on IndiGo international routes. Once you add that, IndiGo's total return cost frequently lands ₹5,000–₹8,000 above Thai Lion Air's all-in fare for the identical journey with the same luggage.
That is not a marginal difference. It's the difference between a ₹22,000 IndiGo return with one bag checked, and a ₹14,000–₹16,000 Thai Lion Air return with the same bag already included.
The second carrier worth knowing: Thai Vietjet Air offers one-way nonstop Mumbai to Bangkok fares from $97 (₹9,118) on July 3, 2026, flying into BKK (Suvarnabhumi). It doesn't include free baggage in its base fare, but its headline one-way prices on low-demand dates rival Thai Lion Air's. On a carry-on-only trip, Thai Vietjet Air into BKK gives you direct Airport Rail Link access to central Bangkok — a convenience Thai Lion Air's DMK arrival doesn't offer.
BOM→DMK vs BOM→BKK — The Airport Choice That Makes the Price Difference
Don Mueang Airport (DMK) and Suvarnabhumi Airport (BKK) are Bangkok's two international airports. The question Indian travellers never ask — and should — is which one serves the flight they actually want to book.
Don Mueang Airport (DMK) is around 17 miles (27 km) from the center of Bangkok — a Grab or taxi ride of approximately 30 minutes in non-peak traffic. By public transport, the A1 bus connects DMK to Mo Chit BTS station in about 1 hour and costs approximately ₹35 (15 Thai Baht). Suvarnabhumi (BKK) is 30 km east of central Bangkok — about 45–60 minutes by taxi and 28 minutes on the Airport Rail Link at ₹130–₹160 (55–65 Thai Baht).
The real-world difference for a traveller staying in Sukhumvit or Silom — Bangkok's main tourist and business districts: DMK is marginally further by taxi but costs less on Grab during off-peak hours. BKK has the faster public transport option via the Rail Link. Neither is a meaningful inconvenience. The ₹5,000–₹8,000 fare difference between DMK-bound Thai Lion Air and BKK-bound IndiGo covers your Grab from DMK to Silom, two nights' accommodation at a budget guesthouse on Khao San Road, and still leaves change.
Thai Lion Air flights arrive at DMK and the check-in counters there close 45 minutes before departure — tighter than most international carriers which close at 60 minutes. This is the one operational detail to know before you book. A 4 AM departure on Thai Lion Air from BOM means you need to be at CSMIA T2 check-in by 3:15 AM at the latest. Set your alarm accordingly.
For Indian travellers who've read our Delhi to Bangkok guide, the DMK vs BKK logic is identical — the airport that saves you money is Don Mueang, and the taxi from DMK to the city is the same 30-minute, ₹280 Grab ride regardless of which Indian city you departed from.
Don Mueang Airport's international terminal is smaller and faster through immigration than Suvarnabhumi — most Thai Lion Air passengers from Mumbai are through arrivals and in a Grab within 25–35 minutes of landing.

EaseMyTrip shows BOM→BKK one-way fares ranging from ₹9,905 to ₹15,645 per person depending on timing and airline. The under-₹12,000 return target is achievable specifically by combining two Thai Lion Air one-way fares on the cheapest January or August dates — or by mixing a Thai Lion Air outbound with a Thai Vietjet Air return on optimal date combinations. The split booking approach is covered step by step in the booking strategy section below.
Cheapest Month to Fly Mumbai to Bangkok in 2026
The month-by-month price pattern on this route differs from most other international routes from Mumbai. Unlike Dubai (cheapest in September) or Singapore (cheapest in July), Bangkok has two distinct cheap windows from Mumbai — January and August — and its peak spike hits harder in April due to Songkran festival demand.
| Month | Avg Return Fare (₹) | Avg Return ($) | Notes |
|---|---|---|---|
| January | ₹12,000–₹18,000 | $128–$191 | ✅ Cheapflights confirms January as cheapest month — avg ₹12,515 for BOM–Bangkok |
| February | ₹16,000–₹22,000 | $170–$234 | 🟢 Good value — Holi hasn't hit yet |
| March | ₹20,000–₹28,000 | $213–$298 | 🔴 Holi spike ±7 days |
| April | ₹28,000–₹40,000 | $298–$425 | 🔴 Songkran (Thai New Year) — biggest Bangkok spike of year |
| May | ₹16,000–₹22,000 | $170–$234 | 🟡 Shoulder — reasonable |
| June | ₹14,000–₹20,000 | $149–$213 | 🟢 Strong value — Thai Lion Air flash fares here |
| July | ₹14,000–₹20,000 | $149–$213 | 🟢 Consistent value |
| August | ₹12,000–₹18,000 | $128–$191 | ✅ Skyscanner confirms August 22 as 2026's single cheapest departure date from BOM to Bangkok |
| September | ₹16,000–₹22,000 | $170–$234 | 🟡 Moderate — still reasonable |
| October | ₹22,000–₹32,000 | $234–$340 | 🔴 Navratri + Diwali spike |
| November | ₹20,000–₹26,000 | $213–$277 | 🟡 Moderate |
| December | 🔴 ₹36,000–₹52,000 | $383–$553 | Worst month — Christmas + New Year peak |
✅ = Best windows | 🔴 = Avoid if budget-sensitive
January and August share first place for a structural reason: January sits in the post-New Year lull when Indian outbound demand collapses after the December peak, and Bangkok's own high season (November–February) is in full swing — paradoxically creating low airfares even though the city is busy. August is Bangkok's monsoon month, which suppresses Western tourist demand exactly as it does on the Bangkok and Singapore routes from Delhi.
April deserves extra attention. The Songkran festival — Thai New Year — falls in mid-April every year. It generates enormous inbound demand to Bangkok from across Southeast Asia. Combined with Indian school summer holidays starting in late April, the Mumbai–Bangkok fare in April is consistently one of the most expensive weeks of the year on this route. Trip.com data confirms April is significantly above the annual average on BOM–BKK, with Thai Lion Air fares spiking well above their January and August lows.

No Visa Required — The Thailand Rule Most Indian Travellers Still Don't Know
Indian passport holders can enter Thailand visa-free for up to 60 days for tourism — no VoA fee, no pre-approval required, no application form at the airport. This policy was made permanent in 2024 and remains in effect for 2026. You arrive, clear immigration with your passport, and you're in. The maximum permitted stay is 60 days.
This matters enormously for the price calculation. Before this rule existed, Indian travellers factored in a ₹2,200 (2,000 Thai Baht) Visa on Arrival fee into their trip cost. That fee is gone. Your Mumbai–Bangkok trip costs what the flight costs plus accommodation — nothing extra at the border.
What you do need at immigration: a valid Indian passport with minimum 6 months validity from your travel date, a confirmed return or onward ticket, and evidence of sufficient funds (typically a bank card or statement — immigration rarely asks, but carry it). Hotel bookings are helpful but not mandatory for most Indian travellers.
One practical note: DMK's immigration queue for international arrivals typically clears faster than BKK's — the terminal handles lower volume and the processing is efficient. Most Thai Lion Air passengers from Mumbai are through immigration and in a Grab within 25–35 minutes of landing.
A full meal at a Bangkok night market — pad thai, mango sticky rice, fresh coconut water — costs approximately ₹180–₹240 (75–100 Thai Baht). The ₹12,000 you saved on the flight is three weeks of dinner.
How to Actually Book Under ₹12,000 Return — The Step-by-Step Method
The ₹12,000 return target is achievable, but it requires a specific sequence of decisions. Every step below removes a cost layer that most Indian travellers leave in accidentally.
Step 1 — Fix your month. January or August. These are the only two months where Thai Lion Air's base fares drop low enough for split-booked returns to approach ₹12,000–₹14,000 total. June is a close third. Any other month, the cheapest achievable return rises to ₹18,000–₹24,000.
Step 2 — Search BOM→DMK specifically, not BOM→BKK. On FlyFlick, MakeMyTrip, or Google Flights, manually type "Don Mueang" or "DMK" as your destination. Thai Lion Air operates 5 nonstop weekly flights from BOM to DMK and will not appear in a standard BKK search. This single step reveals the fares most travellers never see.
Step 3 — Book outbound and return separately. Open two browser tabs — search BOM→DMK in one and DMK→BOM in the other. Look for the lowest single one-way fare in each direction, potentially on different dates within your target month. Thai Lion Air's cheapest one-way BOM→DMK currently starts at $84 (₹7,896) on its lowest-demand dates. Two fares in the ₹6,000–₹8,000 range each puts your total return cost at ₹12,000–₹16,000. You are not required to book round-trip on one airline or on the same dates.
Step 4 — Carry-on only OR verify the 20 kg bag is included. Thai Lion Air includes 20 kg free checked baggage on the Bangkok–Mumbai route — confirm this applies to your specific fare bucket (Promo vs Standard) at checkout. If it does, your ₹7,896 one-way is a genuinely complete fare. If you're in a Promo fare that excludes baggage, add it pre-travel at ₹1,900–₹2,800 per leg online — significantly cheaper than at the airport counter.
Step 5 — Book on Tuesday, Wednesday, or Saturday. Trip.com data confirms Tuesday, Wednesday, and Saturday as the cheapest days to fly BOM–Bangkok, with fares noticeably lower than Friday or Sunday departures. Sunday is the best day to search and book, per ARC data — fares are consistently lower when purchased on Sunday vs Friday. The combination of a Sunday booking for a Tuesday or Wednesday departure on Thai Lion Air produces the best fare stack available on this route.
Step 6 — Apply bank cashback before paying. Before confirming, check your HDFC, Axis, or ICICI app for live international flight offers. Midweek booking (Tuesday–Thursday) activates rotating 8–10% cashback windows (capped at ₹1,000–₹1,500) on Indian OTA platforms. On a ₹7,000 one-way ticket, a 10% cap of ₹1,000 reduces your net cost to ₹6,000 — which is exactly the price point where two one-ways hit ₹12,000 total.
Step 7 — Sort travel insurance before departure. Bangkok's hospitals are excellent and expensive without cover. Before clicking pay on any flight, get VisitorsCoverage locked in — medical coverage up to $1,000,000 for Thailand. A single night in a Bangkok private hospital without insurance can run ₹40,000–₹80,000. For budget trips where VisitorsCoverage's premium is a concern, EKTA starts from $0.99/day at ektatraveling.com.
For flight delay protection, Compensair covers up to €600 for delays and cancellations on international routes — file from your phone, no upfront cost. For eSIM: Saily covers Thailand from $1.99/day with 5G — activate before boarding at CSMIA T2 so you can open Grab the moment you land at DMK. If you're continuing from Bangkok to other Southeast Asia countries, Yesim offers multi-country unlimited data on one plan.

Bottom Line
The ₹12,000 return to Bangkok from Mumbai exists. It requires January or August, Thai Lion Air into Don Mueang, two split-booked one-way fares on optimal dates, and either carry-on only or confirmation that your fare bucket includes the free 20 kg baggage allowance. Most Indian travellers will land in the ₹14,000–₹18,000 range once all that's optimised — which is still the best-value international return fare from Mumbai to any comparable city.
Bangkok is a 4 hour 23 minute flight. No visa, no VoA fee, 60 days to stay. The city has some of the world's best street food, extraordinary temples, and a night market scene that costs less than a Mumbai dinner. There is genuinely no compelling reason to pay ₹24,000 for this trip when ₹14,000 is sitting in the DMK search result you've never opened.
Book smart. Fly cheaper.
