We experienced an unlucky working experience where by we had to depart the aircraft after boarding, shortly before the scheduled takeoff time, and re-board. The reason offered was that a passenger felt unwell and needed to cancel their programs and therefor their luggage needed to be located and taken off. https://share.evernote.com/note/b2d074a5-a2fe-885d-2354-3cee27f9f591
