At what point does the "oversold/nonoversold indicator" or seatcounter say when the actual number of passengers booked (unknown to seat counter) exceed the capacity of the aircraft?

How can a program that has no knowledge of total seats sold have ANY clue as to if a flight has more of them sold than the capacity.

People use this to GUESS at what you think some magical corelation between seats available at a local booking (non-connecting) class and total number of seats available for sale on the aircraft.

I can assure you...this is a very un-reliable measure. When UA promises to tell you the answer to the question, how can you trust another system that gets its information from UA's computers, but is missing 1 of the 2 variables needed?

I respect the fact that you try to find back doors into the information, but the doors don't lead to where you want to go, they just open in the same direction. I would rather go thru the front door when it is guaranteed to lead me where I want to go, rather than just in a similar direction.

But hey, keep on believing that seatcounter has this ability if it makes you feel a sense of security.

UA doesn't even charge for information, only on making reservations/ticketing.
