As a GGL I had my hopes slightly raised in my own head but no beep for me. Had to make do with the upper deck. It's ridiculous. A decade ago I'd have been delighted with a seat on the upper deck and a flat bed. Get a grip

I do find it interesting though. For example, my SFO-LHR flight next week has J9 W0 Y7 B8 H7. Why is it B8 but Y7? I think this was raised on another thread where someone said it's an anomaly/caching issue.
Update: Just checked, its now Y6 B7 H6.
If I worked in the airline industry, i think revenue management would be the place for me.
