MILWAUKEE (CBS 58) -- With snowfall expected through the holiday weekend, travel time may be longer than usual but this holiday season, delays are not the only thing on people’s minds.

After Transportation Secretary Sean Duffy encouraged people to dress up on their flight — some travelers are thinking about what they’re going to wear before takeoff.

“Jeans and a sweater. I tend to be cold, so I’ve got a nice warm sweater on and I’ve got my coat with me,” said traveler Kathy Mullen.

At Milwaukee Mitchell International Airport, travelers are kicking off their holiday weekend.

“We’re going to Virginia, my son and I, we’re there to visit my other son who’s in the Navy,” said Mullen.

It’s expected to be a record breaking week of travel, but a Midwest winter storm could cause some delays.

“I looked at the hotel window this morning and I saw little flurries and stuff like that,” said Jordan Smith, a traveler.

"It can have bigger impacts to the aviation system as the day goes on and more delays pile up so if you can, try to target that morning flight,” said Katy Nastro, a travel expert with Going.com.

With snowfall expected throughout the weekend, travelers are encouraged to arrive at the airport with ample time to spare. This year — some are also thinking about what they’ll wear.

Earlier this week, the U.S Department of Transportation unveiled its plan called the “Golden Age of Travel Starts with You,” encouraging people to dress with “respect.”

“When we think about the Golden Age of travel, we think about luxurious planes and very formally dress people, but we want people to actually understand that that Golden Age of travel was really for a wealthy elite,” said Nastro. “You see all walks of life coming through airports and getting on planes and we should really remember that we don’t want to go back to that Golden Age of travel when airfare was out of reach for the average traveler."

Travelers say they’re focused on comfort — and making sure everyone can get to their holiday plans, safely.

“Dress accordingly, but also make sure you’re nice. You don’t gotta wear a suit and tie or something like that,” said Smith. "Definitely be comfortable but I don’t feel like you need to some in here with pajamas on at the same time.”
