I was also told to get my boarding pass at the gate at some point when I asked about it during a previous transfer at Schiphol.

I didn't need to.

When I checked in online in the KLM app as normal about 36hrs before the flight, it generated both boarding passes. One for my KLM flight, which as normal I could muck about with seating, and also assigned me a random seat and generated a boarding pass for the Transavia flight. So all was well. I couldn't change my assigned seat for the flight (26A, ugh), it was just the boarding pass with no additional options.

I'm Flying Blue Silver but I don't think it made a difference. The one thing I will say is that the seat pitch on the Transavia flight was absolutely appalling, to the point where many 6ft+ people were visibly uncomfortable.

So you should be ok.


On a related note, in early 2024 I booked a similar routing and this time around I was allowed seat selection, and the Transavia part of my schedule was just treated in the app as if it was any KLM flight with all the usual fiddling that can be done. I took 2A, thanks very much. Online checkin seems to be "normal" for this flight too, or at least what we are used to with KLM. So they seem to have integrated their systems more closely, starting 2024 I would reckon.
