Based on the International Air Transport Association calendar, airlines announce the most new flights and routes for the summer travel in April and for winter travel in November. During these months, you might have a better chance of finding an award seat.
In our own research, we’ve noticed that six months out seems to be the sweet spot for finding an award seat.
