United Mileage Plus members can earn triple miles and a complimentary room upgrade when they stay at luxury London hotel The Savoy.
Members who book a stay at the five-star Fairmont property will receive a complimentary upgrade to the next room category.
And those booking a three-night stay will also receive the third night for free, as part of a separate Savoy promotion.
Valid on bookings until March 31, and for stays until the end of the year, Mileage Plus members will also earn triple award miles — that's 1,500 miles per stay for three nights.
The offer is subject to availability of rooms while blackout dates may apply.
