 Well, you'll now need to get to the airport earlier to check your bags. Until recently, many airlines imposed a 45-minute cutoff time to check bags and boarding gates closed 10 minutes before departure. Now, some airlines have a 60-minute baggage cutoff time and boarding gates are now closing 15 minutes before departure. Given those changes, be sure to get to the airport at least 90 minutes before your flight to check those bags. And to the gate, 20 minutes before departure time. Peter Greenberg, CBS News.
