KNOXVILLE, Tenn. (WVLT) - Millions across the country are getting ready to hit the holiday road.
Obviously this time of year, you're dealing with a lot of different weather.
Knoxville got soaked with rain, but people in other parts of the state are dealing with snow.
So for those driving to their destination, you may deal with extreme changes in weather.
The folks over at Fisher in Knoxville had some recommendations before you hit the road. They say to check your fluid levels, such as oil, anti-freeze, transmission.
Tires are also crucial to check, especially if you're going from sunshine to snow.
"That's where having your tires properly inflated and having proper tread depth are going to be critically important in areas like that," said David Rigsby, a Sales and Service Adviser at Fisher.
The extreme weather is making things complicated for fliers having to change plans due to delays or cancellations.
At least two flights to Chicago were cancelled today because of the weather there, so people are going to have to reshuffle plans.
The spokesperson for McGhee Tyson Airport said it's important to keep an eye on the weather. Not only for where you are or going, but also the conditions of any connecting locations.
She says airlines will keep in contact to make sure you can find another way to get to your destination if your flight is cancelled or delayed.
But, the good news is cancellations will not create a domino affect and cause people the next day to miss their flight.
"If you have a reservation for tomorrow, your reservation is for tomorrow. Today is when we are seeing people re-routed or put on different airlines or put on later flights because of some delays in some of the major cities that they connect through," said Becky Huckaby, the McGhee-Tyson Airport Spokesperson
Huckaby also says you should arrive at least 90 minutes before your flight. Lines are long, so arrive early, and be patient because many are trying to get to their holiday destination.
"It really is important to give yourself plenty of time to find a parking space, and to get into the airport and through the checkpoint. There are plenty of things to do on the other side of the checkpoint to entertain you while you wait. But you don't want to get here at the last minute and miss your flight," said Huckaby.
