I have countless times reached LBA from East Yorkshire in under an hour at all times of day or night. I can also get to DSA in 45 minutes (from Leeds and from East Yorkshire). Given that most studies of catchment area dynamics use an hour travelling time as the benchmark, both airports are already well placed in that respect. What they're not well placed to do is compete on the same level as MAN, and that is purely down to size of catchment areas, economic factors and propensity to fly. Yorkshire is not as densely populated as the North West, and not as many air passengers have O&D's in Yorkshire as they do in the North Weat, hence MAN being the place most airlines choose to operate from. Therefore it is important to improve connectivity to MAN so that Yorkshires cities can capitalise on that growth.
