According to their app, a round trip from Beijing to SFO is EIGHTEEN THOUSAND FUCKING DOLLARS for basic economy. Beijing to Newark is 9000. According to Expedia, Beijing to SFO through Newark is 2700 for basic economy. Apparently going halfway around the world and adding a transcontinental flight on the end reduces your ticket price by 15000 dollars?
I had a flight that would cost $600 to go from airport A -> B -> C, but going with the same flight from B -> C was $800 (I even live closer to airport B than to A)
Of course they wouldn't let me book the cheaper ABC ticket and join the flight at B.
