Yes, timings are a major problem on the London Heathrow route, but the real reason the route has flopped to such extents as it has, is because of the knock-on effects of the WW pull-out. I'm surprised no-one has mentioned this sooner. I knew there would be severe knock-on effects, but I didn't know it would be so bad - and so quick to happen.
Like MME4eva said, yes, the Tyne Tees adverts are a good thing, but only if they state the route being advertised. It's the same with GSM, they plastered hundreds of advertisements across hundreds of Arriva and Stagecoach buses all over the north east, but not one mentioned that the destinations being advertised are from MME. You'd think common sense would tell the advertising people to display the origin and destination airports on the actual ads?!
