Route on the map
When to fly
Bangkok stays hot and humid all year, and daylight barely changes, so weather and crowding matter more than long evenings. October is the cheapest month shown, and it can still bring showers as the wet season eases. December and January often feel busier around Christmas and New Year, while June is also priced on this route. Midweek departures are worth checking, and booking early helps if your dates fall in school holidays. The dated fare calendar on this page covers October, November, December, January, February, March and June.
Airlines and what to expect
Start with what each fare includes, because the extras are where prices separate. Easyjet, Eurowings and BA EuroFlyer are the low-cost names; Aegean Airlines, Austrian, Olympic Air and Edelweiss Air are fuller-service; Condor, Sky Express and Eurowings Discover vary by fare, with extras added or included depending on the ticket. Every itinerary connects, and the connection point depends on the airline and ticket. Check whether one booking covers the whole journey or whether you are buying separate tickets.
Arriving — Bangkok
Getting into town starts with knowing which airport you used. Taxis, airport buses, trains and ride-hailing are the usual options from both Suvarnabhumi and Don Mueang, and the transfer can feel long at busy times. Suvarnabhumi is the main international airport; Don Mueang is the older airport and handles many regional and low-cost flights. Give yourself time on arrival, because traffic, queues and the wrong terminal can turn the first hour into the hardest part of the trip.
