SOUTH BEND – The fog we saw caused a mess on Wednesday at the South Bend Regional Airport, and it couldn't have come at a worse time.

Wednesday was the airport's busiest day of travel with 2,500 people boarding flights.

Delays, cancellations and long waits – sometimes it's all part of the holidays.

"Hopefully, we'll see them in a little bit here," said Jim Reiner. Reiner and two of his children drove up from Atlanta to spend Thanksgiving with family. His wife and newborn took a plane. They were supposed to be in by noon, but a half hour later, their plane still hadn't landed because it was too foggy. "It's a 12 hour drive, so that's a pretty long drive. We thought it would be easier to split up, but now it's turning out to be a little longer than what we thought," said Reiner.

The fog caused two flight cancellations to Chicago along with several delays going to and from the Windy City and Denver among other cities.

"It's unfortunate that the weather was like it is today on the busiest travel day, but we can't control mother nature," said Julie Curtis, Director of Marketing and Development at South Bend Regional Airport.

For some people whose flights were cancelled or delayed going out of South Bend, they decided to try their luck in Chicago and hopped onto the Coach USA bus.

"It's okay; it's not anything that's too unexpected, but I mean yeah it's inconvenient, but it's okay, said traveler Lindsay Neuliep. Neuliep was supposed to catch a connecting flight to Minneapolis, but her flight got delayed.

"It was supposed to be at 12:19, but it's delayed now and with the fog, they're having problems landing and I think I'm just going through Chicago Midway," said Neuliep.

“We ask for everybody's patience,” said Curtis. “I think everybody can understand. You just simply look outside and you can see as they drive into the airport, the low visibility."

Patience paid off for the Reiners. Jim's wife and other daughter eventually arrived. They were about a half-hour late, but that didn't seem to bother Jim's daughter Cassandra.

Things are getting back to normal. There were still a few delays Wednesday evening, but that was because of the backup earlier in the day.
