I checked in for my Delta flight to JFK tomorrow. In the check in process, I was sent to the KLM website. My boarding pass is now in Apple wallet, KLM also instructed me to print the boarding pass too. Is that really necessary?

Also, there is no mention of the wheelchair I reserved with Delta at both AMS & JFK for my flight home. Should I be concerned that there is no wheelchair at both airports? I ask because when I arrived at CDG last week, Air France had no wheelchair for me even though it was reserved because my flight did not deboard at a gate but rather we were shuttled to a terminal. That is what the agent at AF told me. I don’t want to have this experience of no wheelchair again tomorrow at AMS.

Thank you for any assistance any of you may have.
