No one likes it when their flight gets canceled. But if there’s anything that can alleviate that annoying experience, it’s the healing power of pizza. Delta Air Lines knows this, which is why it hosted a multi-airport pizza party after canceling 300 flights.

The threat of severe thunderstorms and tornadoes near Atlanta put a kink in many travelers’ plans yesterday, so Delta ordered more than 450 boxes of pizza for affected passengers stuck in Georgia, Tennessee, Louisiana, Ohio, Kentucky, and elsewhere, reports The Atlanta Journal-Constitution.

The grub wasn’t limited to just pizzas, either: Delta customers in Panama City, FL, had 20 trays of chicken biscuits, while people stranded in Nashville chowed down on 60 foot-long subs. Employees at some airports handed out games and coloring books to help keep kids entertained.

“We know it’s not fun to be stuck on the ground somewhere,” Delta corporate communications manager Michael Thomas told paper. “It’s just a small gesture but it’s one that our customers do appreciate.”

It seems to have worked:

Delta has held pizza parties in the past as well: In 2015, passengers got free pizza after their plane cabin filled with smoke during the flight, and just last year, a pilot ordered pizza for everyone on a flight that was delayed due to weather in Atlanta.

At the time, a Delta spokesman said the pizza tactic is part of a broader food movement in customer service.

“It’s part of an effort company-wide when weather disrupts our operation to get food and beverages to delayed customers,” he explained.
