UNDATED (AP) -- Airlines and travel experts agree: holiday travel requires planning ahead, and hoping for the best.
Delta CEO Richard Anderson tells NBC's "Today" show that his airline has been preparing for the Thanksgiving rush, and is "ready for 2 million passengers over the course of the next 10 days."
But he says all the planning in the world won't control the weather. All you can do, he says, is "advance plan" and "hope for good weather."
Weather has already proven to be a problem early in this busy travel week, with heavy fog causing delays yesterday at several West Coast airports.
Travel expert Peter Greenberg has some suggestions for dealing with airports. He tells the "Today" show you can shed the burden of luggage by shipping your bags ahead through a discount service.
And if you don't have to check or pick up luggage, he says you can avoid crowds by arriving at the departures area, and departing from the arrivals area.
