United bringing massive 'high-J' business cabin to more Chicago flights

United Airlines flyers in Chicago will soon have even more opportunities to score business-class awards and upgrades on flights to London.

Beginning Nov. 14, all three of United's Chicago (ORD)-London (LHR) flights will be operated by the carrier's unique "high-J" Boeing 767-300ER, with a massive Polaris business cabin that sports a total of 46 seats (one of which is reserved as a pilot crew rest). You should see the new cabin maps appear beginning Saturday (Oct. 5).

Currently, the airline operates one "high-J" aircraft and two with 30 seats each between Chicago and London, so this change represents a daily capacity boost of 32 seats in business class.

The refreshed plane also adds a 22-seat Premium Plus (premium economy) cabin, with Economy Plus adding one seat, for a total of 47, and regular economy dropping way down from 138 seats to just 52. As a result, economy saver awards and discounted fares may be more difficult to come by, though the increase in business and premium-economy capacity will certainly bring some relief.
