Didn't know that Qatar flew that route...interesting to know that...
I think there's something dysfunctional with Qatar relationship with One World and BA in particular. I hate the way that I'm denied entry to their "Al Mourjan" main Business Lounge at Doha and you're shuffled off to a lounge dedicated to One World types.
It wouldn't be too bad but for the fact that its right under a huge neon bill board sized sign, that illuminates the whole place, constantly changes colour...and threatens to induce a fit...
Limited booze and food as well...
