Jay:
Thanks for the update - your WB stats are right on the money.
Due to the big seat count difference in 788 configurations, I'd expect the remaining 8 788s would be the biggest priority to get through Polaris mod. I'd expect 772GE N77014 and 763 N674UA to remain stored for now and maybe UA will consider 76A Polaris configuration for N674UA as times may dictate a less premium mix for at least the near future. If 763s replace some 772 TATL routes, I doubt the 76L's 109Y seats is enough.
UA has been slowly completing the 319 fleet mod with 12F seats and only 5 remain - each coming through SFO for a 5 days or more get completed. Uncompleted units are currently stored at: DEN: N813UA, N4888U, ROW: N837UA/N838UA, SFO N891UA - the SFO and INT units are probably being reconfigured.
I count 12 752s with slimlines and are stored (all since mid/late March) at:
ROW: N58101/N14102/N13110/N57111/N12116/N14120/N19141
MCO: N17105/N14106/N14107/N12109
INT: N19117
I'm not sure if the configuration was considered with stored aircraft - New configuration at ROW: 7 of 12 (58.3%). Old config at ROW 14 of remaining 28 (50%).
FYI: on the Fleet Site it's pretty easy to view spreadsheets for this info - I've added parked and stored/date/location columns for each aircraft type.

There are also other spreadsheets=, etc. on the Fleet Site to view fleets by livery, Polaris completion/mod, parked/stored aircraft, etc. and are all up to date.
