arrived MAD 8:25 , departure: 16:45 terminal K
Too lazy to go out, we waited at the airport.
We were told that our gate # would be posted 1 hour prior to departure.
OK
Noticing our seats were far apart, I got a new boarding pass issued at the Ibera counter around 15:30. "Yes, as the board says - terminal K"
15:45 I asked an other agent "Yes, terminal K - number will be posted in 15mn"
16:10 : posted as terminal M
same agent "No, it says M but it will be K" (??????)
me : "just in case, how far is M ?" ... "right here, not far" (pointing behind him - on the runway " (????)
16:15 , other agent "terminal M. Go down all the way this side, take the train downstairs"
a hoard of VERY unhappy passengers galloping to the right terminal.
One bright side, the plane was not going to leave with half of the passengers missing (small plane fairly empty).
Thank you Iberia - nearly missing a plane after sitting in the "right" terminal over 8h was a first for us.
