Now through June 17, you can book British Airways economy awards to/from London for 50% fewer Avios. On some routes and dates, this drops the price to just 6,500 Avios each way between the US and London. And, if you don’t currently have Avios, you can easily obtain them by transferring points (1:1) from Amex Membership Rewards, Chase Ultimate Rewards and SPG Starpoints.Here are the basics of the deal:Airline: British Airways-operated flightsRoutes: London Heathrow (LHR) or London Gatwick (LGW) “to over 90 destinations"Cabin: Only for “World Traveller” economyBook by: June 17, 2018Travel dates: September 1, 2018 to May 31, 2019Transfer points: American Express Membership Rewards (1:1), Chase Ultimate Rewards (1:1), Starwood Preferred Guest (1:1 with bonus for transferring 20,000 points)No registration or promotion code.

See privacy policy.But, this deal can be especially good for routes where British Airways isn’t able to (or doesn’t) charge as high of fuel surcharges. For example, you can fly between London and Hong Kong for just 9,750 Avios and $41.Since British Airways Avios are charged per flight leg, you might as well build your own multi-stop trip. For example, you can fly from the US Northeast (Boston, Chicago, NYC, Philadelphia, Washington DC) to London, stop and visit London for as long as you want, then fly to Seychelles for a total cost of just 14,625 Avios:Or, if you want to take the long way from Hong Kong (HKG) back to the US, you can book Hong Kong-London-NYC from 16,250 Avios and $234 one-way:And if you book a route — such as Hong Kong, Los Angeles and Washington DC — that operates using a British Airways A380, make sure to select an upper-deck seat.British Airways A380 upper deck window seats featured storage compartments between the seat and the window.
