I just noticed from May 10 to May 28 inclusive, all fare classes for BA flight 122 DOH-LHR are zeroed out. Looks like light loads on my flight date (May 16) as I am the only seat occupied in F. Only 15 seats occupied in the entire plane. I'm thinking about calling AA and having them change me to the 1:40 AM QR flight, which is the only other flight from DOH to LHR with F since QR dropped their daytime F flight a few months ago (when I switched to the BA daytime flight).
