This is insane. Had I made the wrong choice in rebooking my flights a day earlier or later I would have been very screwed. My international segment with AA 172/171 for JFK-BRU was originally supposed to depart the 29th, I called ahead to rebook for the 29th, best decision ever made. I was gonna try to rebook the return flight for the 7th and 8th... but decided to fly out early instead on the 4th...Looking back had I chose the 7th or 8th I would be stuck in Europe for even longer. What a huge mess.
