Yes, Singapore Airlines provides lounge access to eligible passengers with a layover in Singapore. Your eligibility is based on your class of travel or your KrisFlyer and Star Alliance status, and it is determined by your flight leaving Singapore. Other options, like purchasing a day pass at a pay-per-use lounge, are also available.

Lounge Access Eligibility
Cabin Class: Complimentary for Suites, First, and Business Class passengers. Premium Economy and Economy travellers do not have access unless they hold eligible status.

Frequent Flyer Status: PPS Club and KrisFlyer Elite Gold (or Star Alliance Gold) members have access regardless of cabin class.

The 'Next Segment' Rule: Eligibility is based on the flight immediately departing that airport. For example, if you fly Economy from Phnom Penh but have a Business Class onward flight from Singapore, you get lounge access in Singapore only.

With a layover in Singapore Changi Airport, you can enjoy an extensive range of airside facilities, including themed gardens, quiet rest areas, and family-friendly spaces. For longer layovers of at least around 5.5 to 6 hours, you can consider an official transit tour into the city, subject to timing and eligibility. Shorter layovers are ideal for exploring the airport’s walking trails, viewing attractions, and relaxing in seating areas or transit hotels. Your time at Singapore Changi Airport is more than just a wait — it is an integral part of your journey.

Phnom Penh follows Indochina Time, which is UTC+7 and does not observe daylight saving time. Seattle follows Pacific Time, which is UTC−8 in winter (approximately November to March) and UTC−7 in summer (approximately March to November). This means Seattle is typically 15 or 14 hours behind Phnom Penh, depending on the time of year.

Yes, your baggage will typically be checked through to Seattle when flying from Phnom Penh via Singapore on a single booking with Singapore Airlines.

Through-Check Conditions
For your bags to be sent directly to your final destination, the following general conditions must be met:

Single Itinerary: Both flight segments (Phnom Penh–Singapore and Singapore–Seattle) must be under the same booking reference or PNR.

Layover Duration: Your connection in Singapore must be less than 24 hours. If your layover exceeds 24 hours, it is considered a stopover, and you will typically be required to collect your luggage and re-check it for your onward flight.

Partner Airlines: If your onward flight from Singapore to Seattle is operated by a partner airline, Singapore Airlines has through-check agreements that usually allow your bags to be tagged to your final destination.

You may be able to plan a stopover in Singapore on your Phnom Penh–Seattle trip, 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.
