Might anyone own a Rimowa Cabin Plus luggage, and have you had problems bringing it in the cabin and finding overhead storage for it across UA planes, including regionals? How about any notable limitations when flying with partners?

There are several threads over a the Travel Products board and someone had mention that it fits perfect in the ERJ bins, and that all these planes have standard bins. However, someone countered that it doesn't fit in Finnair's.

I am contemplating on getting one, and I have a flight with UA in December. It will be on an ERJ 175 in domestic First, connecting to a 77W flight in Polaris.

I am currently using a 15 y/o dilapidated Swiss army continental carry-on. It fits perfect in 737/A320 wheels-in most of the time, and back side-down sideways in ERJs. Interestingly, the only wide bodies that I have flown on (UA partners) that cannot take a continental-size cabin luggage wheels-in first are the 767s and 777s. The Rimowa Cabin Plus size appears to be wider, but short in height.
