This morning I flew with KLM on their morning flight from WAW to AMS. I checked in using the internet the previous day. Unlike AMS, at WAW you cannot print your boarding pass at home, you get one at the airport. I picked seat 23F, which is the row before the last one on the 737-400 which was supposed to fly the route.
When I picked up by boarding pass at the airport, it said seat 3A, which is about the opposite corner of the airplane (in fact, it is exactly the opposite corner seating-wise, KLM has some cabinet instead of row 1 on the left side of their 737s).
What's more interesting, seat 3A is business class.
Now I don't mind being put into business class instead of economy, but I do find it rather strange that nobody told me a thing about the seat or class change (but the lady at the check-in desk was friendly enough to let me on the plane with a slightly overweight hand luggage).
I didn't ask about it either, I thought it looked like a business class seat so I thought I'd rather not say anything to make them change their mind. (Usually economy starts somewhere around row 4; besides, the boarding pass looked different than the usual ones, and the class said 'C', not 'M' like on the ticket.)
I imagine that the whole reason for the seat change is that the plane turned out to be a 737-300, which simply doesn't have a row 23.
Does anyone know how such seat changes are decided upon? Because when my boarding pass was being printed at the airport, there were still people standing in line to check in for economy class, so there must have still been some seats more or less available..
P.S. apologies if this post is a little chaotic, but this morning flight left at 6:40am thus I'm having a little trouble formulating my thoughts...
