The Transportation Security Administration (TSA) says the three busiest days for air travel are the Tuesday and Wednesday before Thanksgiving and the Sunday after the holiday. Flyers are urged to arrive at least two hours early for domestic flights and anticipate long lines at the TSA checkpoints.

A record 80 million Americans are expected to travel for Thanksgiving this year, according to AAA projections. The big picture: That's an increase of 1.7 million people from last year's record-shattering figure.
