What is dispositive, and is impossible for us to clearly show without stepping into commercially-sensitive disclosure, is whether full-fare, refundable and one-way business class tickets are frequently sold in the market, which they are. And there's really not a linear relationship between the existence of discounted premium fares and the high-fare travel that drives UA's Heathrow business. United is on record that it generates the highest yields in the New York-London market among its peers.

I know I can't show you public information to conclusively prove the point, but I would posit this: if such travel does not exist in the New York-London... where else would it?
