The very wealthy are going to fly private. Upper middle class could swing this on a case-to-case basis, but not regularly and especially if not if they frequently travel
Other than that, the main difference is the very wealthy having a mentality of getting people to "take care of problems" to a much larger extent. For example, routine tasks like cleaning. An upper MC person might have a weekly cleaner at best. But they still have to load/unload dishwasher, do their own laundry, etc. A very rich person has a full-time housekeeper.
The very rich have circles of people they rely on to take care of problems. Like having "a lawyer" who they go to for and have known for years. There seems to be much more of a sense of personal relationships / loyalty. Almost like the old feudal oaths.
