While this probably won’t last long, American Airlines has increased award availability in business class on routes between the U.S. and Manchester, England. Currently the airline flies from Philadelphia, New York and Chicago to Manchester and all three routes seem to have a good amount of space available.
As many of you know, premium cabin award availability on American has really dried up over the past couple of years. It is rare to see this much space, so it most likely will get snatched up fairly quickly.
