As United already has several flights to Italy (10?) and Rome in particular (3?), this one was a smaller deal than others-- much more limited executive presence, although a very happy Italian consulate was most definitely present. And the party at the gate was still solid, with tons of balloons, cannolis and gelato, coffee, and of course, both speeches and a ribbon cutting.
Onboard was pretty much an entirely ordinary flight, zero commemorative memorabilia at all, not even a card. Ended up sitting next to the #1 on the upgrade list (I was #2) who also loves doing inaugurals, and he and I were both disappointed at the lack of memorabilia here. Aside from the pretty senior flight crew (Italy is obviously a desirable route), in fact not much was notable while on-board. We didn't even get US-Italy flag pins from United. Dinner in premium economy on the flight was a surprisingly serviceable chicken breast, which, extremely oddly, was served with cold soba as a side. Soooooo strange given the side is supposed to be a salad, and this wasn't a flight to Japan; none of it made sense.
Before the flight, took advantage of Priority Pass for a decent meal at Yankee Pier. Would not have warranted any particular note or praise for the food, although service was extremely quick (kudos to them). Next stop was the United Club, which had a pretty bad noodle bar but was still much appreciated considering how much worse the options usually are.
