"The latest government figures show U.S. airlines’ on-time arrival rate so far this year – 74 percent -- is the worst ever. And in June, airlines were extremely full -- with almost 90 percent of all seats occupied in some cases. Have you had to change your booking strategies to cope? Are you booking earlier flights? Fewer connections? Have you had trouble rebooking a flight or changing your departure times? Which airline is the worst to deal with? Post your comments HERE.
