T-minus two days until Thanksgiving and that means sky ways and highways are extra crowded. Travel Editor Peter Greenberg says 80-million Americans are traveling this year and most are taking a full week off instead of the two traditional days. Ft. Lauderdale-Hollywood International is expecting 744-thousand passengers. One-point-nine million are expected at Miami International. So, passengers are being advised to arrive three hours before departure. Tomorrow is expected to be the busiest day at the airport, followed by Sunday as people head back home.
