Just a public service announcement.
I spoke with a Xiamen Airlines office agent and found out cancellation rates are increasing for both international and domestic routes. She said this wasn't idiosyncratic to her airline. It's happening across the board.
I was trying to buy an international flight from Kunming to Los Angeles and she warned me that cancellations are increasing and delays of days are not unheard of after a cancellation. With a 3 day negative test required to enter the USA and a CDC requirement that travel needs to occur in that 72 hour timeframe, I have to reconsider returning end of this month and hope the PSB will kindly grant another 30 day extension.
