I booked a tickets from FLL to JFK with a layover in ATL. Departure time 7:45am, stopping in Atlanta at 9:42am and then continuing on to JFK at 12:45pm, arriving at JFK at 3:05pm. I just came to the realization that 7:45am is WAAAY too early to take a flight. I was really hoping i can change the time. I used 12k sky miles per ticket for 2 passengers. Any advice will be appreciate. I really want to change the time.
