I'm always very wary now about later flights in the day from NCL especially in winter when you have connections to make. Like Exraf says, any small hiccup on an earlier flight in the day and the schedule for the rest of the day has had it. At least with the earlier flight the plane starts out from NCL and your luggage stands a chance of making the connection as well as you!
I'm flying to LAX next month and I see the flight from NCL to AMS is now at 06.05am. It was only a few years ago that this flight departed at 06.30am. Every new timetable seems to bring the departure time forward 5 minutes with the same arrival time!
