With the busy holiday travel season here, Philadelphia International Airport (PHL) is prepared to welcome large numbers of travelers and offers these tips:

Check your flight status by contacting your airline, or call the airport at 800-PHL-GATE. Have your flight number handy.

If you are 18 or older, make sure you have a valid, government-issued photo ID.

Extra time may be needed for check-in and security screening. Check with your airline.

Liquids, gels, aerosols, creams, and pastes in 3.4-ounce or smaller containers may be carried onto the aircraft in a resealable, one-quart, clear plastic bag.
