We have never done a flight this long (New York to Singapore, 18+ hours), and I'm trying to get my ducks in a row before the booking window becomes available in about 2 weeks. Would you rather: depart JFK at 10:30pm, and arrive in Singapore at 5:30am? OR depart Newark at 9:35am, and arrive in Singapore at 5:15pm?
I see pros and cons to each. Arriving at 5:30am in a new country obviously is not ideal for checking into hotel, but I seem to think it'd be an easier flight to sleep on, since you're leaving so late in the evening. Also, we could arrive to JFK in the early afternoon, and depart the same day later that evening, with lounge access in between for dinner time, and no hotel needed. Leaving at 9:35am means we need to arrive the night before and stay in a hotel, however I think 5:15pm arrival in Singapore is easier for checking into hotel. Also we'd need to arrive super early to the airport to take advantage of lounge access in the morning pre-flight. But since the flight is almost entirely during the day, I would think you'd be awake for most of it/harder to sleep? We'll be in business class, so I do want to try and sleep/ rest up as much as possible.
For those that have done this flight, or just long haul flights in general, what are your thoughts? Which would you choose? Any pros/cons I'm missing that I should take into further consideration?
