(CNN) — Diverted because of bad weather in Atlanta, a Delta Air Lines pilot and airport crew turned to the classic solution for many a grumpy passenger: pizza.

As torrential rains swept through Atlanta on Tuesday afternoon, some flights were delayed arriving at the world's busiest airport -- and Delta's home base.

A 2 p.m. Delta flight from Philadelphia to Atlanta was diverted to Knoxville, Tennessee, because of the storms in Atlanta.

"We circled in the air for a while (and) then the captain said we were diverting to Knoxville because of storms over the airport in Atlanta," passenger Khoury Ashooh told the DailyMail

Pizza delivered to the aircraft via baggage cart seemed to cheer everyone up, according to their social media posts.

"We are sitting on a runway stuck on a @Delta flight because of weather," tweeted @RileyVasquez. "So they're throwing us a pizza party!"

"Delta continues with class," tweeted @BillyTheKidWitt. "Stuck due to weather and the crew ordered everyone pizza. #deltaairlines."

The Philadelphia to Atlanta flight, which usually takes about two hours, landed three hours late at 7 p.m.

Passengers on other delayed Delta flights reported similar feasts, and it turns out that the pizza was the result of a broader edict.

"It's part of an effort company-wide when weather disrupts our operation to get food and beverages to delayed customers," Delta spokesman Morgan Durrant said.

No word as to whether coffee and Delta's famous cookies were served for dessert.

It was a bad weather day for both Delta and Atlanta's busy airport.

Delta had 106 cancellations (3% of its daily flights) and 653 flight delays (21% of its daily flights) on Tuesday, Daniel Baker, head of Flightaware.com, wrote in an email. At the Atlanta airport, "there were 173 cancellations across all airlines (mostly Delta and their regional partners) as well as 802 flight delays."
