A
9.0 Wonderful
Pros:This was my first flight in Polaris and I was very impressed. I had a window seat and the cabin is configured so that you do not have to climb over someone else to exit your seat. In some other business class cabins on other airlines this isn’t always the case. This reminded me of a BA first class cabin setup. Nice large TV screen and window locker to hold items you want to access during the flight and also a small locker with a water bottle, headphones etc. Food was good and there is an option of do not disturb that you can switch on from your seat. One passenger slept through this meal and the crew were able to reheat his meal. Final comment. I had a 70 minute layover between landing from Hamburg and leaving to the US. Heathrow is a big airport and on a previous flight with BA I have missed a connection with a 90 minute layover. However with United, it was very efficient. No time to visit the lounge but made it to the gate with approx 10 minutes to spare.
