Follow-up:

I agree with the comments about great attitude of the people with both the outbound and (Horizon operated) return. The outbound was on an old 737-300 (many of the signs also in German, so probably an old LH or Swiss Air plane). Typical coach seat, not that great, close pitch. Return was on a regional jet (2-2 configuration). I was not able to get an exit row but did get an aisle seat. Although I am not that tall (5'11"), the pitch was uncomfortably tight, as my knees were touching the next seat the entire time(the occupant fortunately did not try to recline). (I had a similar experience recently on an American Eagle operated RJ; no MRTC on those either.)

We did get Fritos with the drinks on the return, which was a nice touch.

Edited to add: Several hours after the flight had landed, I received the flight notification (text message) on my cell phone that the flight would be departing on time. Nice to know.
