United Airlines on this route

United Airlines serves ATL–BKK through its hub network, usually with one connection. The nonstop flight time is about 18h 11m.

The lowest one-way fare we have on record for this route is $558 on United. Fares like that usually show up on off-peak days and for travel booked a few weeks out; an agent can check whether a similar fare is available for your dates.

Because Delta Air Lines treats Atlanta as a hub, this pairing tends to have frequent departures throughout the day. Emirates and Qatar Airways also compete here, which keeps fares in check.

This is a 9,150 miles journey, about 18h 11m in the air on a nonstop, which puts it firmly in long-haul territory: baggage allowances, seat selection fees, and stopover options change the real cost of the ticket as much as the base fare does.

When to fly

For long-haul travel, mid-January to March and the shoulder months of October and November usually bring the lowest fares; June through August and the December holidays cost the most.

On this specific route our fare history shows November as the cheapest month and December as the most expensive, a spread of $952 between the two.

Tuesday, Wednesday, and Saturday departures are usually the cheapest days on long-haul routes; Friday and Sunday are the most expensive. Early-morning and late-evening flights are often priced below the midday departures.

For international travel, booking two to five months ahead usually gets the best fares; inside three weeks, prices rise sharply. Peak-season travel in summer and over the December holidays should be booked as early as possible.
