CHICAGO — Friday is expected to be the busiest day of the holiday travel season at Chicago's airports.
City officials anticipate O'Hare and Midway will see 250,000 travelers today and be among the busiest airports in the nation, with an estimated 5 million passengers during the Christmas, Hanukkah and New Year's travel period. That's a more than 2% increase over last year.
People are advised to arrive at the airport two hours early for domestic flights, and three hours early for international travel.
City officials are also cautioning travelers not to pack marijuana during this travel period. Marijuana becomes legal in Illinois on Jan. 1, but if TSA officials find it in a suitcase, they'll notify police to verify the amount packed and the age of the owner of the marijuana. That will delay travelers and security lines.
Also, if a passenger is traveling to a place where marijuana is not legal, they could be arrested at their destination.
