UPDATE #1: We are adding new cities as we find them — there are now fares starting from $1795!
UPDATE #2: Oneworld pricing appears to either be dead or extremely limited from Atlanta, but still alive on many dates from Pittsburgh. SkyTeam availability still appears to be very strong as of 2:30pm Eastern time. This fare sale is not likely to last, so we recommend booking if you find dates that work for you.
We have discovered an all-out business class fare war on all three alliances from a wide range of cities in the US to London and Paris from $1799 round trip, with other cities possible/likely. I am adding dates and cities as we find them. Even better prices may be possible by Extreme Stacking British Airways discounts to save big.
Additionally, Alaska Airlines is offering large bonuses for travel on British Airways in premium cabins — I believe most of the British Airways fares would be “I” fares that should earn 250% mileage flown on Alaska before any elite bonuses). For example, Detroit to London with a stop in Chicago each way should earn about 21,000 redeemable miles before any elite bonuses. You might be able to stack the incredible value of the American Express Business Platinum 50% rebate with Alaska’s bonuses to create yourself a nice little mileage run on this sale.
