I'm sorry I thought I replied but I see now it's not posted. We're not thinking about Mexico, that was just an example. Anyway, I've read about experiences about traveling with expired GC and a notice both with and without issues with various airlines, but that was from few years ago. Can't really see anything from recent years particularly last year so I can have a better understanding and know what to expect. If anyone has or read about any recent experiences in such case and share some links I would appreciate it. Thanks!
