Which programs have award seats on this route?
Of the programs we sell, in business class: Alaska Atmos Rewards on American Airlines on 1 day from $1,026; American AAdvantage on American Airlines on 76 days from $1,349; American AAdvantage on British Airways on 28 days from $1,711; British Airways Avios on British Airways on 33 days from $1,994; Alaska Atmos Rewards on British Airways on 18 days from $2,004; United MileagePlus on JetBlue on 23 days from $2,191, and 6 more, listed under Ways to book. Counted over the 89 days in the calendar.
How much do the taxes and surcharges add?
It depends on the airline flying the seat, not the program. On a typical seat one way: British Airways $734, American Airlines $6, Delta $6, JetBlue $6. Some airlines add a carrier surcharge to award tickets on their own flights; the others charge little more than government taxes. Every total on this page already includes them.
What is the best business class from Boston to London?
British Airways, American, Virgin Atlantic, Delta and JetBlue with Mint fly it nonstop from Logan, all with a lie-flat business seat. It is the shortest flight from the US to London.
What about a return?
The calendar covers Boston to London one way. In miles a return is two one-ways with no return discount, and the taxes on the way back can differ. Tell us both dates and we price and book the pair.
Can I use miles I already have?
Yes. On any program under Ways to book, tap “Already have some miles?” and enter your balance: it reprices to the cost of the shortfall. Our minimum order applies, so a small shortfall may leave you with spare miles. AAdvantage is the exception: we deliver it as a ready account with the miles already in it, so it cannot be combined with your own balance.
Do you show programs you don't sell?
No. The dollar prices only cover programs we sell, so seats in other programs are left out, and some of them can be cheaper in miles. If you hold those, use them, and if you'd rather we found and booked the seat for you, ask us.
