Most major airlines have areas of their website where you check-in for your flight ahead of time (typically 24 hours in advance). What's the advantage of checking-in on the web before arriving at the airport? It speeds up curbside check-in if you are checking bags, and if you aren't you can proceed directly to the gate with the boarding pass you'll be able to print before you leave home.
