Arrive at the airport in plenty of time—for short or domestic flights, it’s advisable to arrive at least 1.5 to 2 hours prior to departure, taking into account traffic and security lines.

Arrive at the airport in plenty of time—make sure to arrive at the airport at least 3 hours prior to departure for international flights to accommodate check-in, security, and immigration procedures.
