Most journeys from Seattle to the United Kingdom connect at Singapore Changi Airport, which offers indoor gardens, art installations, rest areas, showers, and a wide range of shopping and dining options. For longer daytime layovers, you can consider an official transit tour into the city when available and if your schedule and entry requirements allow. For shorter stops, staying airside lets you make the most of lounges, quiet zones, and family facilities. Your time at the airport is more than just a wait — it is an integral part of your journey.

London and Manchester share the same time zone. From roughly late March to late October, they observe British Summer Time (UTC+1), which is typically 8 hours ahead of Seattle (Pacific Daylight Time, UTC−7). During the rest of the year, they switch to Greenwich Mean Time (UTC+0), usually 8 hours ahead of Seattle when it is on Pacific Standard Time (UTC−8), though the exact offset may shift by one hour around the dates when each region changes its clocks.

Yes, your baggage will typically be checked through to your final destination in the United Kingdom when flying via the layover airport on a single booking with Singapore Airlines, provided both flight segments are under the same booking reference (PNR), the connection is under 24 hours, and, for partner-operated onward flights, a through-check agreement is in place.

You may be able to plan a stopover at the layover city on your journey to the United Kingdom, 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.
