When I fly Southwest, you’re supposed to check in starting 24 hours before to get a decent position in line. You can pay extra to get a guaranteed spot in boarding group A, but as long as you check in on the dot you’ll get at least B. Wait till the last minute and you’ll be stuck in a middle seat in the rear on most flights. Not sure how it works with other airlines, though.
