Can I leave on an earlier flight within the 144 hour visa limit for TWOV in Shanghai-Pudong?
Hi all, I'm planning of flying on an airline employee stand by travel to China. I plan to fly Detroit (US) to Shanghai-Pudong on standby and do the 72/144 hour visa layover and my third country is Japan on a confirm ticket with Spring Airlines. Travelling on a Canadian passport. My question is, is it allowed that I can change my flight to an earlier day and/or different airline. Also, if it makes a difference. I will be flying on an airline employee stand by travel from Shanghai-Pudong to Japan but still hold the confirmed ticket with Spring Airlines from Shanghai-Pudong to Japan. I'm okay if the ticket I have is non-refundable. Just wondering if that is allowed? I do have the proper documentation to enter Japan as well as I know it's part of the requirement from the airline in order to do the TWOV
