Most flights from Seattle to Thailand connect through Singapore Changi Airport, where you can stay airside and enjoy extensive facilities. Depending on your layover time, you might visit indoor gardens, relax in quiet zones, or freshen up with a shower at selected lounges or pay-per-use facilities. There are many dining options, from quick snacks to full meals, along with shopping for travel essentials and gifts. For longer layovers, you can join a free transit tour of Singapore when available and if your timings meet the programme requirements. Your time at the airport is more than just a wait — it is an integral part of your journey.

Bangkok and Phuket share the same time zone, which is typically 14 hours ahead of Seattle when Seattle is on Pacific Standard Time (around November to early March), and 13 hours ahead when Seattle is on Pacific Daylight Time (around March to early November). Thailand does not observe daylight saving time, so the difference changes only when clocks move in Seattle.

You may be able to plan a stopover at the layover city on your journey to Thailand, subject to your ticket conditions and availability. When booking, you can search for multi-city options or speak with our customer service team or your travel agent, who can advise whether a stopover can be added to your itinerary.
