This sounds like one of those unicorn flights. LHR to Chicago with only 32 passengers total, and 20 of them in Polaris. That’s wild.
I can imagine the service being next level when the crew basically has more staff than passengers. Flexible, attentive, relaxed, handing out 767 trading cards like it’s a souvenir flight.
An empty economy cabin on a transatlantic is something you almost never hear anymore. Getting in an hour early on top of that is just icing.
Those are the flights that remind you why flying can actually be fun sometimes.
