U.S. citizens over 18 must show a federal or state-issued photo ID, such as a passport, birth certificate bearing official seal or driver's license. Foreign passengers must show a passport or U.S. residency documents. Photocopied IDs are not accepted. Passengers arriving at check-in less than 60 minutes before departure will be turned away, and no passengers will be allowed to board the plane less than 20 minutes before takeoff.
Luggage must be checked in at least 60 minutes before departure and carry-on baggage at the gate 20 minutes prior. Federal regulations allow for random inspection of all baggage.
