Aviation experts in Chicago say the city's airports will see more than 1.9 million passengers this Thanksgiving.
Wintry weather conditions across the East Coast, including rain, wind and snow in places like Boston, Philadelphia and New York City have led to flight delays and travel advisories.
Travelers at O'Hare Airport were experiencing some delays and cancellations Wednesday, but it wasn't as bad as many expected.
"It what it is. It's holiday travel," said Brittany Rall as she waited for her flight.
David Simon flew in to Chicago from Boston and didn't experience any issues.
"Everything was listed on time. All the flights before were on time. From the reports, we were expecting delays, but we got there early and had some relaxed time at the airport," Simon said.
Airport officials suggest passengers constantly check their flight's status and arrive to the airport early.

"Try to get there two hours in advance of your flight, and that way you will allow for traffic getting through ticketing and getting through the security line," said airport spokesperson Karen Pride.
Experts predict more than 43 million Americans are expected to travel over the holiday weekend, according to travel group AAA. About 37 percent of those people are expected to depart on Wednesday.
