I have many reward points with Southwest Airlines. They do not have any available flights to Pensacola on the day I need to fly. I can however use points to fly into Atlanta then catch a Delta flight into PNS. How hard is it to maneuver the Atlanta airport from one airline to another? I would have approximately 2 hours to complete this...all with a 2 year old and other adults. I do understand that I would need to retrieve our luggage and then re-check in with Delta. Is 2 hours long enough? Has anyone ever done this? Any help you can give would be greatly appreciated!
