So, I booked my flights over 2 months in advance for May 1-5. I already have a flight change. Literally arriving 2 minutes later in Miami (7:19am instead of 7:17am) but then leaving about 25 minutes earlier to Chicago and then about 25 minutes longer stay Chicago before moving on. (note, this is AA airlines). So, what are the odds that by the time I go, I will have anything close to the flights I originally booked?
