We're flying from Manado to Sorong, presumably on Lion, to board a liveaboard. Our very-reliable travel agent is comfortable with our departing Manado on the day of embarkation. Understanding that there's always some risk of delay, is it a terrible idea to count on Lion to get us there on the day the boat departs? I've seen a good bit about relatively-minor delays, but not too many about outright cancellation.
