JSCL,
I presume you were on a Q400 ? May I comment that the yesterday's weather wasn't great for flying anyway, coming in on a A320 into LHR, some quite nasty turbulence over France. Another problem could have been the ATC computer failure backlog, maybe some planes where flying lower than one would like. Also various showers over London. I thought to myself: Glad I'm not on the Q400 now ! BTW I made it through Ealing and Birmingham unthreatened and unharmed. But was a narrow miss. But that's off-topic here. Well, apart from maybe indicating the Brum does have bigger problems than other cities and this might be why BHX is losing routes...
