I couldn't find this on the forum, so here's the question. I go to school in DC and I am flying CO back to EWR tomorrow (10/26). The weather is looking nasty, and it seems that it doesn't take much for them to cancel this flight. I think that there is a strong chance that it will get canceled, so I was wondering if I could rebook the flight for a week later? In other words, if it gets canceled, I am almost certainly going to get rebooked for Saturday (10/27). I am coming back Sunday (10/28). That really makes the trip more of a hassle, so I wanted to know if I could request to rebook my flight for the following Friday (11/02) instead of the Saturday (10/27)? My gut says that since it would also change my return flight, it would incur some kind of charge, but I was just wondering if it could be done.
