I would do the trip without thoughts, but I'm "at home" within the EU, so my threshold can be lower than foreigners'
Why not make also a photocopy of your passports data page?
Even for NPU country residents of only non-EU/non-EEA citizenship doing intra-NPU international travel, airline reps and non-fixed station national authorities in immigration or customs control positions turn people out sometimes despite having the residence ID card issued by one of the NPU countries. It's really a situation of YMMV for non-EU/non-EEA citizens. Most often it works out fine when within the Schengen Zone. A photocopy of a passport doesn't necessarily change a thing for such travel, and it may help (but not generally with the airlines) but it may hurt (with airline reps or national authorities who may consider it suspect). I keep photocopies of my passport biodata page and it has worked sometimes when not flying.
