What time should I arrive at the airport

At least 90 minutes prior to your departure. Plan extra time if you plan to park at tye economy lot.

personally I try 2 hours before....depends on the time of flight too.For example if it's evening definitely recommend 2 hours before.,also what ever time your flight departs the start boarding 20 minutes prior

Depends say 90 min for local and 3 hrs for international. However it depends in practice on the airline and time of year. I'd allow additional time for events like spring breaks and holiday seasons.
