What To Expect in Polaris Business Class

Polaris is United’s international business class product, and it is very solid — especially if you can enjoy some time in the United Polaris lounge before your flight. Unfortunately, that isn’t an option with this sale as there is no United Polaris Lounge at Boston Logan Airport.

However, the inflight experience is still quite good and you can expect:

  • Lie-flat seats in your suite with custom luxury bedding by Saks Fifth Avenue
  • Complimentary Away amenity kit featuring travel essentials including premium skincare items from Sunday Riley
  • Elevated inflight dining service, plus complimentary drinks and snacks
  • Complimentary checked baggage and Premier Access benefits

Final Thoughts

Overall, this can be a great way to save $250 if you were already getting ready to book a United Polaris flight from Boston to London. The dates are a bit limited, but this could be useful to people traveling for the holidays.

As always, check the competition first, especially now that Virgin Atlantic is flying its brand-new A330-900neo featuring The Retreat Suite to Boston, and don’t forget that JetBlue Mint continues to be a fantastic experience.

Whether you are looking for a roundtrip flight or just a one-way, flying United Polaris is a great way to cross the pond, and saving a few hundred bucks doing so is always welcome!
