The airlines have cut back the number of flights due to the pandemic. With fewer seats available and an increased demand, they can raise the prices and recoup their losses from over the past year. It will probably be a good year to book early. I booked over a month ago for a January vacation - $560 r/t out of Boston with pretty good travel times and connections - of course that's on American, so it will probably all be changed, which, of course, is the downside of booking early. Can' Win! lol.
