Refile flight plans have been around for over 30 years. People's Express Airline used to use them from Newark to West Palm when the planes were full and fuel was tight. They used to file to Jacksonville Fla., then if all went well and they didn't need an alternate, refile to West Palm. Purely a means to get the customer where they want to go in a timely fashion when business is GOOD!
I'm sure the the People's Express customers appreciated getting where they wanted to go WITH their underwear!
