Our flight departs Buffalo at 07:25 a.m. According to Southwest website, we should be at the airport 1 hour before the flight. The Buffalo Niagara International Airport website says to be at the airport a minimum of 1.5 hour before flight. Our airport hotel shuttle doesn't start until 06:00 a.m so it will be tight just to make the Southwest suggested time. I plan to do the 24 hour online check-in before. Should I be concerned about cutting it close for being at the airport 1 hour before flight departure?
