Not one viable business route then... morning out/evening in
Did you know that less than 10% of people travel out and back for business in one day? Depends what your definition of a "viable business route" is. At the moment if you want to travel from the Doncaster region to AMS you have to go to EMA or MAN. Who wants to do a day trip where you have to add at least an hours commute to each end before you even start your flying? Much better to have a days work, travel in the afternoon, meet your client for an evening meal, have a good nights sleep in a hotel and then have your business meeting the next day don't you think?
