Flights out of Lindbergh Field have a chance of being canceled Monday morning -- if they haven't been already.
A blizzard on the East Coast has shut down several airports there - creating havoc in the rest of the country, including San Diego.
Typically, there are still many Christmas travelers rushing home the Monday after the holiday. Blizzard-like conditions from the Carolinas up through Maine have caused a post-holiday headache for those trying to get home.
Travel plans could change throughout the day, so passengers are being urged to keep checking carriers' websites or giving them a call.
More than 1,400 flights were canceled out of one of New York's three airports alone. New York's John F. Kennedy and LaGuardia airports and New Jersey's Newark Liberty International Airport were still closed Monday morning but could re-open later in the afternoon. Delta canceled 800 flights.
Travelers out of LAX are stranded too -- Delta, American Alaska and Jet Blue. All airlines with flights from Los Angeles International Airport have had to cancel or delay flights because of the weather.
Airlines hope to get things running better by Tuesday.
Adding another wrinkle in the mix: Because this is holiday travel time, most of the flights were full, so there could be even more re-scheudling once the airlines are back up and running.
