One week ago, I embarked on the longest nonstop journey of my life — for the second time. Singapore Airlines operated the world’s longest flight, from Newark to Changi Airport, until it was forced to retire its flagship route, along with the gas-guzzling Airbus A340-500, in November 2013.Since then, a handful of other airlines have fought for that record-breaking title, but even Qatar’s 9,074-mile journey from Doha (DOH) to Auckland (AKL) will have to make do with runner-up — a new aircraft capable of operating the nearly 10,000-mile journey just made its debut, finally marking the return of Singapore SQ21 this month.This time around, I got to spend 18 hours (and change) onboard SQ’s first Airbus A350-900ULR. Even in business class, it felt like the journey would never come to an end. Naturally, the first thing people ask, is ‘what did you do for all that time?’ I could tell you, of course, but given the novelty of this ultra-long adventure, I figured it’d be more fun to mount a GoPro, and keep the camera rolling from gate to gate:So, how did I end up occupying my time? Let’s break it down…Hour 1: Taxi, takeoff and figuring out what to eatHour 2: Changing into pajamas, surveying movies, Singapore SlingHour 3: Lunch! And an incredible 2006 Chateau Rauzan-Segla BordeauxHour 4: Dessert, cheese and some chamomile teaHour 5: Getting ready for a long post-meal snoozeI didn’t go to sleep right away, though — Singapore partnered with Canyon Ranch for some wellness enhancements for this special flight, and the company’s CEO told us that it’s best to give yourself a couple of hours to digest before hitting the hay. That’s more or less impossible to pull off on a six-hour redeye, but with another 14+ hours left to go after our first Singapore 21 feast, delaying sleep a little bit longer felt like an entirely reasonable request.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
