Is it cheaper to fly into Bangkok or Phuket?

Bangkok is almost always significantly cheaper. If you want to go to the islands, fly into Bangkok first and take a cheap domestic flight (AirAsia or Thai Vietjet) to your secondary destination.

What is the best day of the week to fly to Bangkok?

Tuesday and Wednesday are consistently the cheapest days to fly. Avoid Fridays and Sundays, which can add 20% to your ticket price.

Booking flights to Bangkok like a pro

Use Google Flights to track prices 3-4 months in advance and aim for mid-week departures to save at least $150. Always book directly through the airline's website to avoid third-party agency headaches if your flight gets cancelled or delayed.

Set up a price alert. Enter your departure city and Bangkok (BKK) into Google Flights. Toggle the 'Track Prices' button to receive email alerts. Do this at least 12 weeks before your planned departure.
Select the right airport. Most international flights land at Suvarnabhumi Airport (BKK). If you see a significantly cheaper flight to Don Mueang (DMK), verify it's not a budget regional connector that requires a different terminal or airport transfer.
Choose your layover wisely. If flying from the US or Europe, aim for a single layover in hubs like Doha (DOH), Dubai (DXB), or Singapore (SIN). Layovers under 2 hours are risky; ensure you have at least 3 hours for international-to-international transfers.
Book direct. Once the price drops to your target range, go to the airline's official website. Never use a site like 'CheapFly-X' or unknown aggregators; they charge high fees for changes and are notoriously difficult to reach when plans go wrong.
