Qatar
Almost no doubt that Bristol will see Qatar operating regularly from BRS within 12 months. The region has long been on the radar at Emirates, who lack suitable aircraft.
Bristols' impressive passenger growth seems to be following the same direction as Birmingham in sweeping up capacity not available at LHR.
I fully expect to see BRS continue strong growth through the next decade.
My inkling is that Qatar will announce BRS shortly after the government pronouncement on new runway capacity for London (most likely more long grass) using the chance to grab a headline or two..
