It doesn’t matter if there is a gate open
we were told the gate was open so we taxied to our gate. it still took 1 hour after we were told the gate was open to get blocked in. 45 minutes of that was waiting for rampers 250ft short of the gate.
Edit: i guess the good news is that we don’t have automated docking that blocks you in automatically as soon as it says “STOP” and you still have to wait for the jet bridge.
