Seen this too many times (me included) - with marriages, cruises etc. where people end up stuck overnite in airports with wedding presents in hand, or have to literally fly all over the world to catch up with the departed ship at the next port because their "weakest link" flight got cancelled leaving them with no alternatives, (and they planned to arrive the same day as the cruise departure), and they had no travel insurance.

Especially with interlining (multi-airline) flights to remote destinations, just be prepared that you may get there a day later. Therefore, the established rule of thumb is to always arrive at least a day before an important event - better safe than sorry.
