Re Qatar , I certainly wouldn't rule it out yet, in fact a few crew that I know say their are strong rumours it will be starting soon.However whether crew have access to inside info that is 100% reliable I don't know.
They initially announced plans to serve BHX about a year ago - it would be nice for it to come to fruition, but we had our doubts around AI and look what's happened there. I'm sure if they were to start 'soon', then we should hear an announcement before the end of the year at best.
The Air India announcement shows some full fare longish haul airlines are interested in BHX, that should add hope to our Qatar aspirations perhaps.
And possibly a new transatlantic service (though I assume that's a little more complicated).
