Was on the last flight of the night from STL to CLT, a year or so before the demise of TWA. Summertime thunderstorms had delayed the previous flight, and most of the passengers booked on my flight thought they'd be smart and try and rebook on the earlier, delayed flight. As I had my free upgrade confirmed for the later flight, I stuck with it. The earlier flight left 10 minutes before mine, 95% full. Unfortunately for TW, they needed both planes in CLT for the next morning return flights, so they flew my and two PAX in Y on the later (albeit by 10 minutes) flight.

The FAs invited the Y PAX up to F, and then they sat down with the 3 of us and kept the booze flowing. Great flight.
