If he had to be in HEL for an early morning business meeting today, he was stuffed. He would have been stuffed even if he had booked this itinerary on one ticket. Whatever protection or care one might (reasonably or unreasonably) expect from OW, it cannot extend to chartering a private jet at short notice to convey the pax to HEL just because they've missed their onward flight.
