I recall a service revision of a few years ago being called Polaris 2.0 internally, around the time when the wine flights and bloody mary carts went away! It prompted to me to go back into the archives and make a bit of a timeline for the Polaris product. It's been something of a yo-yo:
December 1, 2016 - Polaris service launches, replacing United BusinessFirst and United GlobalFirst with Polaris branding. Champagne flute/chocolate tray PDB, new serviceware, new bedding, "full" Polaris experience as originally planned
May 1, 2017 - Reduced provisioning of mattresses/gel pillows, small pillow cut from standard
May 1, 2018 - Wine flights and bloody mary cart discontinued, replaced with standard cart with cover, pre-departure chocolate cut, pre-poured PDB. (I thought this was Polaris 2.0)
July 1, 2018 - All seats provisioned with gel pillow
February 1, 2019 - 1 FA cut from most WB Polaris cabins, some mains boarded pre-plated. Introduction of the oversize dog bowl casseroles.
April 1, 2020 - One-tray Polaris service due to COVID panic.
October 1, 2021 - United outsources in-house catering division (noteworthy because I believe this decision is why United has encountered so many problems in restoring competitive meal service across the system)
February 1, 2022 - Trial of new "3-step" service on FRA-ORD/IAH/EWR/IAD, LHR-ORD (cocktail service/linen + all-at-once tray setup + dessert cart)
March 1, 2022 - 3-step service rolls out to rest of Polaris system
August 2023 - Trial of new 3-course service flow on ORD-HND/GRU/TLV (return of appetizer cart with salad on tray setup + hand-run main + dessert cart)
September 20, 2023 - Announcement of "Polaris 2.0" (TBD?)
Let me know if I missed anything. The net result is a product that remains degraded over its initial concept, but at least the trendline is back pointed up!
