“How can the government allow an airline to leave you stranded,” said  Mike Benter who was frustrated to learn his Delta flight was canceled when he arrived at Miami International Airport.

Delta, with its biggest hub operation in Atlanta, was hit hardest.

American Airlines, Southwest, United and JetBlue also canceled and diverted dozens of flights because of the Atlanta problem.

Miami International Airport officials said altogether 12 flights were canceled and 4 delayed on Monday.

“The flights they made for me start tomorrow. They go from Miami to JFK, from JFK to Charlotte, and then finally to Atlanta,” said Joe Palano who was frustrated with his re-routing on Delta.”They’re not helping me at all. I have no idea how to get my money back or what to do. I’m going to try another airline or rent a car or something.”
