Singapore Airlines is having some exceptional Black Friday specials. Fly one of the world's top-rated airlines to Asia or on one of its fifth freedom flights from the U.S. to Europe. Fares start at $447 roundtrip.
You may find lower fares on mainland Chinese carriers for some of these routes, but I would consider flying Singapore Airlines if the dates work for you. The service on Singapore Airlines is almost always reviewed as a 5-star service and it may be worth paying a little more for the experience. These rare price drops on Singapore Airlines means it won't cost you too much more to fly on a more reputable carrier.
Travel dates and restrictions vary slightly by route. The fares to Asia are all advertised for departures from the USA between January 10 - June 9, and July 16 through October 31, 2019. All travel must be completed by October 31, 2019. European routes are blacked out for peak summer travel. The lowest fare on most routes is for travel on Mondays, Tuesdays, Wednesdays, and Thursdays, with a $50 each way surcharge for weekend travel.
Tickets must be booked by November 26, 2018.
