The fact that you’re flying KL should help you – less bags to offload, provided most pax continue to AMS, of course.

After customs you’ll need to leave the terminal and walk 10 minutes to Terminal C which is used for domestic flights. AR’s cut-off check in time used to be (still is?) 50 minutes before departure and you can use the SkyP for bag drop off. Security for domestic flights is a non-issue.

My instinct tell me this is a bit tight, but provided KL is on time it’s doable. I asked if you were on a single booking because then AR would be forced to pay for a hotel if you don’t make it. Otherwise they’re usually quite liberal with rebooking for the next flight but won’t open the wallet for accommodation.

Maybe worth calling AF to check if they can do a single booking? The Plat Line has done marvels for me in the past.
