When I was booking an overnight hotel in Buffalo for our flight to Florida in February, the hotel agent was saying that there is new direction that you need to be at airport 2 hours in advance of flight. We leave at 6:45am and since there is no customs, and we'll print boarding passes night before, I'm thinking being at the airport by 4:45am is a little extreme! We were hoping to have breakfast at Homewood Suites at 5:00am and then head over at 5:15 on shuttle. We've been through Buffalo airport atleast 4 times and have never taken more than 30 minutes to get through Security to gate. I think this is plenty of time being at security by 5:30 is good enough - what do you think?
