How Do I Find Cheap Flights to Bangkok From the US in 2026?
To find cheap flights to Bangkok from the US in 2026, search both Bangkok airports, aim for February or March (Priceline's cheapest international months), leave on a Thursday, compare Trip.com, CheapOair and Skyscanner by final total, and book through ShopBack US; the same method works for Hong Kong, Seoul, Manila, Bali, China, India and Vietnam.
ShopBack US is a free rewards app, website and browser extension. You start your booking from the booking site's page on ShopBack US, book as usual on that site, and part of what you paid comes back as cash once the trip confirms.

How do I find cheap flights to Bangkok from the US?
Cheap flights to Bangkok from the US come from five habits used together: searching both airports, staying flexible by a few days, flying in a cheaper month, comparing the same itinerary across booking sites, and booking through ShopBack. Work through them in this order.
- Search both airports. Bangkok has two: Suvarnabhumi (BKK), the main international airport, and Don Mueang (DMK), the city's second airport. A connection through another Asian city can land at either, and the two can price differently on the same day.
- Flex your dates. Use the calendar or flexible-date view on the booking site and compare three or four days either side of your ideal dates.
- Pick a cheaper month. According to Priceline, February and March usually offer the best international fares, while December is the most expensive.
- Pick a cheaper day. Priceline says Thursday is usually the cheapest day to depart on an international flight, Sunday the priciest, and a Monday return can trim as much as 12% off a fare.
- Compare, then book through ShopBack. Line up the same flights on Trip.com, CheapOair and Skyscanner by the final total, then open ShopBack. The last step before you book flights or hotels: open ShopBack.
Thailand's own seasons matter too. Our guide to the best time to visit Thailand for lower prices covers when hotels and flights tend to cost less.
Cheap flights to Bangkok 2026: cheapest months and days
The cheapest months for flights to Bangkok in 2026 are likely to follow the usual international pattern: February and March are typically the best value and December the most expensive, according to Priceline's flight guidance at the time of writing. Priceline adds that a January return can be costly because of post-holiday demand.
| Priceline's guidance for international flights | What it says |
|---|---|
| Cheapest months | February and March |
| Most expensive month | December (January returns can be costly) |
| Cheapest day to depart | Thursday |
| Priciest day to depart | Sunday |
| Cheapest day to return | Monday (as much as 12% less) |
| Cheapest round-trip pattern | Leave Saturday, return Tuesday (up to 30% less when dates are flexible) |
| Day to book | Tuesdays often bring the lowest prices, with fares rising toward the weekend |
Priceline itself says the booking-day pattern is small and "isn't enough to call it a travel hack", so treat it as a tie-breaker. The month and the departure day matter more. These are general patterns, not price promises, so always check live fares for your own dates.
Cheap flights to Bangkok: best deals from the US in 2026
The best deals on flights to Bangkok in 2026 come from pairing a cheap month and day with a few booking habits.
- Mix one-way tickets. Priceline says booking two one-way flights on different airlines can produce a cheaper round trip.
- Try mystery fares if you are flexible. With Priceline's Express Deals you pick the general flight time, Priceline shows possible airlines and the number of stops, and the exact flight is revealed after booking, in exchange for discounts Priceline says can reach up to 50% off retail fares.
- Use price tools. Skyscanner's Whole Month view and Price Alerts help you spot the cheapest dates on a route and catch a drop.
- Use the 24-hour window. US rules require covered airlines to hold a reservation at the quoted fare without payment, or let you cancel without penalty, for at least 24 hours after booking when you book a week or more before departure. Booking sites set their own terms, so check them.
- Count the bags. Compare fares with the bags you will actually take, since the cheapest fare often leaves out a checked bag.
- Compare the price after ShopBack, not the sticker price. Two fares that look the same can end up different once part of one comes back as cash.
Trip.com vs CheapOair: cheap flights to Bangkok price comparison for 2026
Neither Trip.com nor CheapOair is cheaper on every Bangkok flight, so compare the identical itinerary, meaning the same flights, times, cabin and fare type, by the final total including bags. Each site has its own strengths.
| What to compare | Trip.com | CheapOair | Skyscanner |
|---|---|---|---|
| What it is | Booking site for flights, hotels and more, with a wide range of Asian routes | US booking site for flights, hotels and packages | Comparison site that sends you to an airline or booking partner to book |
| How ShopBack shows the amount | A percentage that varies by booking type | A fixed cash amount by booking type | A percentage, for bookings with certain Skyscanner partners only |
| Last step | Book through ShopBack | Book through ShopBack | Book through ShopBack |
How to run the comparison:
- Find your best flights on Skyscanner, which shows prices from many airlines and booking sites in one search.
- Price the same flights on Trip.com and CheapOair.
- Add bags and seats on each so the totals are like for like.
- Open the winner's page on ShopBack and book there.

What is the cheapest way to fly to Hong Kong from the US?
The cheapest way to fly to Hong Kong from the US is usually a flexible-date search into Hong Kong International Airport (HKG) in a cheaper month, comparing nonstop and one-stop flights on the same days, then booking through ShopBack.
- Nonstop vs one stop: nonstop flights save hours; a connection through another Asian hub can cost less. Compare total trip time alongside the fare.
- Months to avoid: December is Priceline's priciest international month, and Lunar New Year in late January or February is a busy travel week across the region.
- Compare: search Skyscanner, then price the same flights on Trip.com and CheapOair, and book the winner through ShopBack.
What is the cheapest way to fly to Seoul from the US?
The cheapest way to fly to Seoul from the US is to search Incheon International Airport (ICN), Seoul's main long-haul gateway, with flexible dates, leave on a Thursday where you can, and compare one-stop routes against nonstop flights before you book through ShopBack.
- Airport: long-haul flights land at Incheon (ICN). Gimpo (GMP), closer to the city, mainly handles domestic and short regional flights.
- Timing: Priceline's international pattern points to February and March as typically the best value. Korea's Lunar New Year and Chuseok holidays are busy travel weeks, so check fares around them.
- Compare: price the same flights on Trip.com, CheapOair and Skyscanner by the final total.
How do I find cheap flights to Manila?
To find cheap flights to Manila, search Ninoy Aquino International Airport (MNL) and check Clark International Airport (CRK) as a second option, keep your dates flexible, avoid the December holiday rush, and compare the same itinerary across booking sites before booking through ShopBack.
- December is peak: Priceline names December as the priciest international month, and the holiday season is a busy time to fly to the Philippines, so book early or pick another month.
- Compare three sites: Trip.com, CheapOair and Alternative Airlines, which is also on ShopBack US, all sell flights to Manila. Line up the same flights by final total with bags.
- Mix one-way tickets: a one-way out on one airline and back on another can sometimes beat a round trip.
What is the cheapest way to fly to Bali from the US?
The cheapest way to fly to Bali from the US is usually a one-stop or two-stop itinerary into Ngurah Rai International Airport (DPS) in Denpasar, which is Bali's only airport with scheduled commercial flights. Compare connections through Asian and Middle Eastern hubs, then book through ShopBack.
- Trip.com vs Qatar Airways: Qatar Airways connects through its Doha hub; Trip.com and CheapOair show combinations across many airlines. Compare the same total trip time and bags on each.
- Stopover cities: routing through a city such as Singapore, Seoul or Bangkok can open more fare options. Check each leg's bag rules if you book separate tickets.
- Packages: if you need a hotel too, our guide to booking a Bali vacation package without overpaying compares bundles with separate bookings.
How do I find cheap flights to China?
To find cheap flights to China, search more than one gateway city, avoid the big holiday weeks, and compare the same itinerary on Trip.com, CheapOair and Skyscanner before booking through ShopBack.
| Gateway | Airport codes | Good for |
|---|---|---|
| Beijing | PEK, PKX | Beijing and northern China |
| Shanghai | PVG | Shanghai and the Yangtze River Delta |
| Guangzhou | CAN | Southern China |
- Holiday weeks: Lunar New Year and the National Day holiday in early October are among China's busiest travel periods, so fares tend to rise then.
- Open-jaw tickets: flying into one city and out of another can save a domestic flight back.
- Trip.com: strong on routes within China and connections through Chinese hubs.
How do I find cheap flights to India?
To find cheap flights to India, choose the airport closest to where you are going, compare nonstop flights with one-stop routes through Gulf hubs, and compare the same itinerary on two or three sites before booking through ShopBack.
- Airports: Delhi (DEL), Mumbai (BOM), Bengaluru (BLR), Hyderabad (HYD) and Chennai (MAA) are the main long-haul gateways.
- Air India vs CheapOair: Air India, India's flag carrier, sells its own flights, including nonstop routes between some US cities and India, while CheapOair shows fares across many airlines. Compare the identical flights on both by final total.
- Gulf connections: Etihad Airways connects through Abu Dhabi and Qatar Airways through Doha, and both are on ShopBack US. A one-stop route can be cheaper than a nonstop, at the cost of a longer trip.
- Festival season: the Diwali period and the December holidays are busy for travel to India, so book early if you need those dates.
How do I find cheap flights to Vietnam?
To find cheap flights to Vietnam, search Ho Chi Minh City (SGN), Hanoi (HAN) and Da Nang (DAD), consider flying into one and out of another, avoid the Tet holiday week, and compare the same flights on Trip.com, CheapOair and Skyscanner before booking through ShopBack.
- Open-jaw: Vietnam is long from north to south, so arriving in Hanoi and leaving from Ho Chi Minh City, or the reverse, can save a domestic flight back.
- Tet: Vietnam's Lunar New Year holiday, usually in late January or February, is the busiest travel time of the year.
- Connections: most flights from the US connect through an Asian hub. Compare total trip time as well as price.
Book your flight through ShopBack
The last step before you book flights or hotels: open ShopBack. It changes what the trip costs you after you pay, because part of what you paid comes back as cash once the trip confirms.
Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles you have to save up and redeem.
Your effective price is what you pay minus the cash ShopBack returns, at the live rate or amount shown on each booking site's ShopBack page.
How to do it:
- Find your best itinerary and compare it on two or three sites.
- Open the ShopBack US app, website or browser extension and go to the booking site's page, such as Trip.com, CheapOair or Skyscanner.
- Tap through and book.
- Our guide to earning on travel bookings explains each stage.
Trip.com note: Book Trip.com flights through ShopBack without a code.
Using a travel credit card and ShopBack on the same flight
You may be able to earn your card's travel points and still book through ShopBack on the same flight, because the card's rewards come from the card issuer and follow the issuer's rules. Whether your card earns depends on your card's terms. Our guide to ShopBack and credit cards in the US has the details.
Mistakes that make a cheap flight to Asia expensive
- Searching one airport only. BKK and DMK, MNL and CRK, or Hanoi and Ho Chi Minh City can price differently on the same day.
- Comparing fares without bags. The cheapest fare can cost more once a checked bag is added, especially on separate tickets.
- Booking into a holiday week by accident. December, Lunar New Year and national holidays push fares up across the region.
- Paying first and remembering ShopBack later. A booking usually cannot be added afterwards, so start from ShopBack before you book.
