Bingo
Bingo has several meanings. In combat the pilot would call bingo, meaning I need either to get back to base or hit a tanker.
In the civilian world it means we are out of here and heading to an alternate airport.
Many moons ago, sitting in the right seat of a 727 holding north of Atlanta. The Captain had added additional fuel, about a hours worth, just cause the forecast was for lots of fog and low visibility. We were just starting the decent when the first hold was assigned. We were about FL240. So the burn is not to high. Then get a couple of step downs to about FL180. Now we are hearing lots of flight below and above us heading to alternates. The Captain started noting were each seemed to be diverting. Calls to the company asking where they would like the divert, if we do, to be. Greenville and Spartanburg are open and suggested.
The long a short of it is we called our ops at each airport and both said the ramp area was getting full and did not know how many more jets could be handled with out starting to close the place down. Remember Tenerife. We had already worked out a bingo, but then readdressed the issue and added another twenty five or so minutes to the bingo. About ten minutes later we started toward Greenville. Well into the decent ATC advised us that the ramp was full and only one runway was open, cause jet were parked everywhere. The company call with the same information and said the had room for us at Spartanburg. We landed with about 30 minutes remaining. We parked on the taxi way leading from the ramp. The place was all but full.
The only advantage was we got refueled first, cause no one could leave the ramp area till we moved on.
