Officials at Dulles International, National and Baltimore-Washington International airports suggest that travelers avoid traffic and parking headaches by leaving their cars at home and using public transportation.

Motorists determined to brave the holiday crush are urged to use the airports' satellite lots for parking or dropping off passengers.

Airport officials offered the following advice and information on the alternatives:

DULLES AND NATIONAL

Motorists dropping off passengers can park free for 20 minutes in lot 2 or 3, or for 10 minutes in a satellite lot. At Dulles, the grace period is 20 minutes in the daily and satellite lots.
