I guess they paid more, the old setup was ridicolous however with Aircoach having to load through the emergency door on the right side of the road, the whole layout is much better now and much friendlier for passengers as a whole with a lot more room and bunching causing less problems than it did over a few years ago. To Aircoaches credit they seem to ahve invested quite a bit in actually getting many more staff out helping passengers since they moved to the prime position. It's swings and round abouts about positioning really, as DB had the main position for ages.
