I once boarded a DanDare flight from Inverness at 8am en route London.
We boarded on time and no dramas except we were rather surprised to find that the aircraft was already half full as it was actually the 7am Glasgow flight as the London one had gone tech.
'We' got airborne on time but of course had to drop off our Glasgow pax so we would arrive in London about 30-40 minutes late.
However the Captain, having made the usual apology, then announced that the bar would be open and free. 8am! However there were a number of red neck oil workers on board and the whiskies were soon flowing.
