To those who like to travel or travel a lot, here is a good way to earn yourself a free airline ticket.
When an airline fully booked a flight there are always stand-bys trying to catch the flight just incase someone doesnt show up or cancel their flight last minute.
Anyways, this past weekend I made a trip to Canada and I flew United. My flight consisted of 2 layovers because that was the only time slot available that worked with my schedule at the moment. I had a layover in vegas and chicago, The vegas layover had a 4 hr wait til my next flight to chicago.
While I was in LAX waiting for my flight to vegas the announcer notify us that our flight is fully booked and are looking for volunteers to take a later flight. My original flight to vegas was 645pm and my connecting flight to chicago was 1130pm. The announcer then said that the next flight is 8pm, so I jumped on the opportunity to volunteer and let hem know I am willing to give up my seat. At first they were hesitant becuase I had a connecting flight but then they realized I had enough time since it was only a 45 min flight to vegas via LAX.
After giving up my seat, in return they gave me a free ticket voucher on the spot good for 1 year and within the 48 states with 2 weeks advance for booking. Not bad for waiting an extra hour.

I remember reading an article about this awhile back and never though I would actually end up doing it.
