And that's especially true in cases of severe weather, such as happened this week when hundreds of scheduled flights were canceled on account of intense thunderstorms in Atlanta.
Following a massive storm Wednesday which hit Atlanta, Delta Air Lines has announced that it was forced to cancel an estimated 3,000 flights this week.
ATLANTA (AP) - Delta Air Lines said Friday it has canceled about 3,000 flights this week as it struggles in the aftermath of a storm that hit its big hub airport in Atlanta.
Delta teams are working around the clock to get customers safely to their destinations while bringing our operation back to normal following Wednesday's record series of severe thunderstorms that resulted in a almost all-day ground stop in Atlanta - Delta's largest and busiest hub.More news: McConnell reaches out to Romney about possible Senate bid
Delta says it is still getting planes and crews back in position for flights.
Delta's Atlanta hub is also the world's busiest and on a blue-sky day, our people efficiently accommodate well over 150,000 people per day.
Delta was having trouble rebooking passengers because there weren't many empty seats on later flights.
Delta Chief Operating Officer Gil West on Thursday apologized for the airline's performance in the wake of the storm, saying that its "recovery has not been ideal". From Atlanta to Valdosta, the website showed the 10:06 a.m. flight as "past schedule" while the 2:09 p.m. flight was cancelled. Delta is also offering to waive change fees for those who rebook their plans.
