I think in your case the biggest question mark will be the passport queue which is always unpreditctable since you never know if/how many machines are working which you should be able to use with a US passpor). Security lately has never been an issue for me (both Schengen/Non Schengen), being a business class passenger (regardless of airline iirc) will grant you access to the priority queue. Occasionally they are very eager to do a 2nd check on pretty much every bag though.

So it probably should go very smooth and fast (has taken me < 10min from the initial boarding pass scan to passing passport check including walking), but some of those factors can change the duration dramatically, especially the passport check if it goes full manual.
