United Airlines flew its new Boeing 777-300ER plane – outfitted with the new Polaris business-class cabin – from Chicago to San Francisco on Monday and I got to ride along.

The “Polaris plane” goes into regular service on Thursday, February 16, on a domestic flight (Newark to SFO), with international Polaris routes scheduled to start in March, with flights from San Francisco to Hong Kong when more of these planes arrive.

Here are some more snaps from the flight. More to come.

United CEO Oscar Munoz was on hand to welcome guests and scan boarding passes.

Special design features (and friendly crew members, of course) welcome passengers on board.

Saks Fifth Avenue bedding – pillows, blankets, throws – and more welcome passengers to their seats.

The new seats require a special harness seat belt, which flight attendants teach you how to put on.

More snaps tomorrow…
