I spent $910 for a roundtrip United flight from Newark to London — and it was worth every dollar when I got my first upgrade to Polaris. Here's what the business class flight was like.

I've been a member of United's Mileage Plus program for 31 years and have flown 479,533 miles with them. That puts me just shy of halfway to my goal of earning lifetime gold with United by flying one million miles. In August, I flew from London Heathrow to Newark, New Jersey. This was the first time I had ever been upgraded to their Polaris Business Class. The experience was so good that I did not want to leave the plane.
