Of course employees are hearing lots of rumors. Key decisions and final designs are of course tightly under wraps. However, there are some themes across the multiple "leaks."
1. The globe will continue to be used. The globe stands for United being a leader amongst global airlines and therefore there is no interest in casting it aside. The globe will remain on the tail. The globe will be updated and "modernized." The gold and white will be dropped and the new globe will be in shades of blue to depict depth and dimension. This is consistent with the globe used in the Polaris cabin. [This would look pretty sharp.]
2. The Tulip will return in limited use. Somewhat similar to AA's bold tail and flight symbol but UA will use the globe as a "design element" -- e.g., tail, cabin, catering service ware, accent walls in terminal/lounges/gate areas -- and the Tulip will be used selectively as a logo -- e.g., next to the United name. [This one seems sketchy to me.]
3. Gold will be dropped.
4. Select colors from the new palette *may* be used, e.g., in the Tulip, the cheatline, etc, but more likely incorporated into things that can be easily switched out over time, e.g., menus in Polaris, cocktail napkins, advertising, etc -- i.e., not as expensive as a new livery.
5. The cheatline will be consistent across the fleet and consistent with the 787 and Max.
6. The objective is to move away from the half United half Continental branding and create a more unique United branding for the future without a comprehensive re-branding effort -- i.e., "our airline."
7. Most people prefer a tweak and modernization.
Again, the above is just a synthesis of current rumors. Time will tell.
Referring to your points:
1. Fine by me but it needed updating years ago. People call it the "Disco Ball" for a reason.
2. This, should have been considered since the beginning of the merger but Smisek was way too arrogant to do so. AA/US and DL/NW both did this on the tail to represent the carrier that doesn't exist anymore. Yet many viewed not keeping the "U" was some sort of a hostile corporate takeover by CO (in some ways it was.)
3. Makes sense as it's not evident anywhere in the new uniforms.
4. Also makes sense as a "secret logo" and Polaris already has it's own logo as well.
5. OK cool.
6. Yeah, that's like common sense at this point. "Merger of Equals" was a stupid strategy and didn't work out. They got more serious about this after the PR disasters back in 2017.
7. I'd say if the above happens it's more than just a tweak and many are ready for it.
