A quick look on Expertflyer.com shows me
VS Reliability stats
VS27 Dep 11:15am - 22% / 68m
VS15 Dep 12:55pm - 25% / 114m
BA Reliability stats
BA2037 Dep 11:40am - 79% / 21m
That's pretty damming, only 22 - 25% leaving on time and between the two flights and AVERAGE delay of over 90mins ! god forbid you turn up when they're having a bad day [:(!]
Definition of those figures from Expertflyer.com is 'The Reliability is the On Time Percentage and the Average Delay in Minutes of the flight over the last two months.'
I'm due to fly out with VS on the 27th of Dec, and you know what - I'm beginning to dread it

I'm not sure that an average performance like that over the last 8 weeks can be put down to anything other than a serious institutionalised problem, no matter how pro-Virgin you may be ?
... or shoot me down in flames if I've missed something here
