Christmas Travel Schedule Changes

More of a heads up, but I've noticed both American and Delta have had major schedule changes for flights in December/Christmas/New Year's. Take a look at your reservations if you had anything booked already. On Delta, their online tool will allow you to change to airports in the same area (think JFK/LGA/EWR or MIA/FLL/PBI) and also different flight times. The change should show up as $0 for any other flights. If you call they won't change anything unless it's over a 2 hr schedule change so try online or in the app first. Any questions feel free to ask
