this is from the SDC policy link on the AS website
- For "red-eye" flight departing between 12:00 a.m. and 3:59 a.m., the new desired flight may depart as early as 10:00 p.m. on the day prior to your original departure.
United does too, as you can move flights within 24 hours. So you could move a 1:00 AM red-eye to lunchtime the day before (space available of course) if you want.
