United Airlines and Continental Airlines have announced that members of each carrier’s frequent flyer program who have earned elite status will receive unlimited, complimentary domestic upgrades on flights operated by both airlines when space is available. Continental’s elite-level frequent flyers also will have complimentary access to United’s Economy Plus seating, offering additional legroom near the front of the Economy cabin. United’s elite-level frequent flyers will have complimentary access to Continental’s Premium Seating as well. These new benefits will begin to roll out in mid-2010. Unlimited domestic upgrades and preferred economy class seating for elite-level frequent flyer members are the latest additions to the suite of benefits available to United and Continental customers since the two carriers announced a global partnership in June 2008 and since Continental joined the Star Alliance Oct. 27 — benefits that include new access to dozens of cities around the world, recognition of elite status, and the ability to accrue and redeem miles on each other’s flights.
