I've done quite a bit of flying this year. > What's the low down on airports these days? They are crowded and understaffed, as least as far as the major hubs go. > Has security changed much from a decade ago? The TSA lines are longer and the Pre-Check system does little to alleviate the crowds. The average traveler can't read signs and understand simple tasks. > Is it better to check or carryon luggage with wuflu rules? For short trips I carry on a bag. If I'm staying longer I check luggage. This one aspect isn't really noticeably different. > Do I need to be concerned about getting kicked off a flight for not wearing a mask in firstbuisness? Hell yes, you need to worry about it. The flight attendants I've encountered are not in the mood to hear anything like logical arguments or common sense. They've been told to enforce the mask mandates and they do it.
