In my mind there are several scenarios:
1. Fly into the day of departure and use HAL airport transfer. Late Arrival Protection should apply fully. That is, if the flight is delayed and you risk missing or actually missed the ship, HAL will do what it can to get you boarded on time or meet the ship in the next available port. This is how I understand FlightEase’s Late Arrival Protection works.
2. Fly into some days before the day of departure but still use HAL airport transfer on the day of embarkation. That is, you return to the airport on the day of embarkation to meet HAL transfer. Specifically, I’d return to the Amsterdam airport. If there is a flight delay:
2a. If the flight is delayed but you still get to the departure city before the departure date, Late Arrival Protection doesn’t apply because you aren’t late.
2b. If the flight is delayed to such an extent that you DO miss the departure, would Late Arrival Protection work in this case? I think it should but don’t know.
3. Same as 2, but you use private transfer to the port and not use HAL’s transfer. Then, I don’t know how Late Arrival Protection works under scenario 2b.
By flying into the departure city 2 days ahead, I hope the chances of 2b happening is minimized.
