Had to call Friday AM as my CVG-DCA flight was parked on the tarmac at Reagan waiting for a gate to open. Knew there was no way to make my connection as we were late departing CVG. Tried the app to book, but nothing showing available to MCO. EXP line was answered in less than 5 minutes and the wonderful agent was somehow able to get me on the next flight despite it showing J0, Y0. Ended up being a long day as FL was a mess with thunderstorms, but made it home.
