BALTIMORE - BWI airport is gearing up for what could be a busy day after weather may cause significant delays across the east coast.
Tens of millions of Americans are on the move for the annual November trek to see family and friends, feast on turkey and pumpkin pie, and rediscover the joys of their hometown on Thanksgiving.
You probably know the drill: packed airports, crowded flights and lots of out-of-state license plates on the road.

All eyes are on the weather, which can turn a simple trip into a nightmare -- cue visions of Steve Martin and John Candy struggling to get to snowy Chicago in "Planes, Trains and Automobiles."
Travelers faced stormy conditions in the Pacific Northwest, the threat of floods and severe storms in the South, lots of rain in the Northeast and the possibility of snow in parts of New England.
On Tuesday afternoon, weather-related flight delays were reported at airports including Philadelphia International, O'Hare, Newark International, LaGuardia and John F. Kennedy International.
But the threat of bad weather is not keeping people home.
AAA projects that 42.5 million Americans will travel at least 50 miles during the Thanksgiving weekend, an increase of 4% from last year.
Slightly fewer people are choosing to get to their destinations by plane.
About 23.2 million travelers will fly over a 12-day period surrounding Turkey Day, a 2% drop from last year, according to a forecast by the Air Transport Association of America.
Unlike last year, when the "National Opt-Out Day" movement against airport body scanners threatened to snarl security lines across the country, air travelers are not facing the prospect of protest-induced delays. (The Opt-Out Day turned out to be a non-event.)
The TSA says it's preparing its work force for a "smooth holiday travel experience for travelers."
The busiest air travel days for the Thanksgiving holiday period are expected to be Sunday, November 27, and Monday, November 28, the Air Transport Association of America said.
If you're flying into or out of Los Angeles International, Chicago's O'Hare International or Orlando International, brace yourself for lots of company. Those will be the nation's busiest airports this Thanksgiving, based on flight bookings, according to Orbitz.com.
(And in case you're wondering, Mineta San Jose International in California and Kahului Airport in Maui, Hawaii, will be the least busy.)
