A few years ago I was flying home (Detroit) from Reno on the Sunday after July 4, which is a super-busy travel day. I'd been in Reno for 5 days attending a convention of a social group to which I belong.
While we were in the terminal, they had a request up on the monitor at the gate asking for something like 6-8 volunteers due to the usual overbooking situation. I wasn't paying close attention, but they did get enough volunteers to accept whatever "deal" the airline was offering.
After we boarded and were in our seats for about 10-20 minutes or so, the pilot got on the speaker and said, due to the heat, lack of wind, altitude, weight of the fully-loaded plane, etc. they needed
15 volunteers to get off the plane
just so the plane could take off. They were offering a hotel night (back at the same hotel where I'd just been), meal vouchers for dinner and breakfast, a seat on the first flight out in the morning, and a domestic flight voucher.
For the first time ever (and I basically lived out of a suitcase for much of my career) I was able to take advantage of such an offer. As I got out of my window seat and squeezed past my 2 seatmates, they both thanked me profusely.
I disembarked (with a few other volunteers), walked straight over to the car rental counter, rented a car and drove up to Lake Tahoe to enjoy the rest of the afternoon.
I didn't stick around to see how long it took before the flight was finally able to take off. Don't know if they got enough volunteers or if they had to drag anyone off the plane.
