If my flight leaves at 2:05pm Sunday what time should I be at the airport?

I suggest 12 Noon for a 2:05 flight. This airport is smaller than LAX, but it still takes time to park, ride the shuttle (if you're parking off property), drop off luggage, get tickets, pass through TSA and walk to the gate. (Depending on which airline the walk takes 1 to 10 minutes.)

Arriving an hour and a half before your flight is adequate at this airport.

Best is 1.5 hours early. Say no later than 12:30
