United has been slow to retrofit its fleet with new Polaris business class seats. According to the Polaris Tracker website United maintains only 11 planes have been retrofit with these seats since the program was announced two years ago.
But that doesn’t mean they’re doing this now. There’s a spreadsheet somewhere that suggests a plan exists which adds a lot of Polaris-equipped planes later, such that adding up planes brought into the fleet with the new seats divided by days gets them an average of 10 days. But it’s seems pretty clearly backloaded.
It’s also worth noting that there is no announced plan to ever put these seats in Boeing 787s and those are the planes that fly really long distance routes like Los Angeles and San Francisco – Singapore, and Houston, Los Angeles and San Francisco – Sydney.
So far United says only 3 Boeing 777-200 planes have the new seats. This is the workhorse of the fleet:
This is the aircraft that’s getting international premium economy first, and that product will become available this month.
As they retrofit more 777-200s they’ll have both Polaris business seats and premium economy, which helps incentivize them to start rolling Polaris business on these planes it seems.

American and Delta already have a premium economy product. American has it on most of its international fleet. Delta has it on Airbus A350s.
