This one still raises my hackles because it was the fault of the FA.

I was on KLM DEL-AMS in a window seat of my choosing. I was barricaded in by a couple that was sleeping on each other, but they weren't bothering me.

About an hour into the flight, the FA comes up and tells me there are empty rows on the other side, or rows with empty middles. I confirmed with him that there would be a window before gathering all my things, disturbing the sleeping couple, and moving to where he directed me.

As soon as I got settled, the man who'd been occupying the seat the FA had just put me in came back. Apparently it was his assigned seat and he'd just been in the lav.

Irritated, I got up and moved to the aisle in that row, pointedly looking at the FA. My new row-mate was a chatty rural-type Indian (my husband is Indian; this is not me being racist) who was far too fascinated with me, asking me question after question before finally curling up and laying down in the window and middle seat in the fetal position with his feet touching me.

As angry as I already was over being lured from my quiet window seat for no good reason, having this guy's feet on me really put me over the edge. Of course, the "helpful" FA disappeared, never to be seen again.

Between this and other experiences with KLM involving AMS and DEL, I will never fly KLM again (and I will never connect through AMS if I can avoid it. Ugh).
