I've told this story before: Almost 30 years ago girlfriend (since married 25 years) & I showed up for Continental flight EWR-LAX with economy tickets (we were poor grad students). Go to the gate & check in with the gate agent. She says, Oh! You are on tomorrow's flight! It was totally our mistake & we just showed up the wrong day. She says, Take a seat & we'll see what we can do. Turns out the flight was oversold in economy & people were flipping out at the agents, yelling & gesticulating, etc. We just sat there quietly waiting, boarding started, people were still freaking out. Finally after the plane had apparently fully boarded, the gate agent called us over, handed us two boarding passes, and thanked us for being patient & not joining the freakout. We looked at the BPs & they were for 1EF.
