I just found a lifehack on how to determine your departure gate when it’s not yet displayed on the board. Go to planefinder net, enter your flight, and it shows the tail number of the airplane for that specific departure. Click on the link with the tail number, and it shows where the plane is arriving from—the gate it arrives at is known much earlier than the gate from where the new flight departs. So head to this gate, as it’s almost certain to appear on the board by the time someone gets around to updating it.
Yes, everything will go awry if they change the plane. But it’s very unlikely that the airplane will change, as any replacement has to be the same model otherwise it causes chaos with the already assigned seating, and airplanes are not changed often (although it has happened to me several times). Nonetheless, there’s nothing to do at the airport, and playing the game of guessing the gate is interesting.
