A weather waiver has been proactively issued for customers traveling to, from or through 18 cities in the Midwest, including Delta's Minneapolis-St. Paul hub ahead of the latest winter storm system impacting the region.

The waiver allows customers traveling to, from or through the affected cities on Feb. 23 and 24, to make a one-time change to their travel plans without incurring a fee.

As always, Delta's team of meteorologists continue to monitor the storm and share regularly updated forecasts with teams in the airline's Operations and Customer Center as well as in the affected airports, where delays and cancellations are possible.

Customers are encouraged to check their flight status on or the Fly Delta Mobile App. Customers can also get updates sent directly to their mobile device or by email with One-Time Flight Notification.

Preparing for cold weather operations

Helping set up the airline for winter, Delta made investments to its people and operation. With new uniforms designed by Zac Posen and manufactured by Land's End, Delta employees were equipped with a number of cold-weather uniform pieces now being used in their first winter season.

Also well before the beginning of the winter season, Delta invested millions of dollars in de-icing capabilities, to help ground crews manage efficient operations during winter events.
