This Thanksgiving could be one of the busiest travel weekends on record

ST. LOUIS, MO (KPLR) - It's the day before Thanksgiving and more than 48-million people are expected to travel for the holiday. The Transportation Security Administration says it could be one of the busiest holiday travel seasons on record.

If you're flying this THanksgiving, you might have to spend more time waiting in line to get through security. But take heart, your flight is more likely to be on time.

The nation's largest airline trade group, Airlines for America says Wednesday is projected to be the third busiest day of the travel, with 2.55 million U.S. airline passengers. The Sunday and Monday following thanksgiving could see 2.81 million and 2.64 million passengers.

Airlines will keep a close eye on winter weather near major travel hubs. If bad weather hits the big cities, it could have a ripple effect across the country. Chicago O'Hare is one of the three busiest airports this holiday and a lot of planes out of Lambert go through O'Hare.

When it comes to travel by car, 43.5 million Americans are planning a road trip this week. Low gasoline prices around the nation has led to more drivers on the nation's highway system this year, so expect gridlock this holiday season.
