That’s what some passengers will be required to endure when China Eastern Airlines launches a record-breaking direct flight between Buenos Aires and Shanghai this December. To comply with crew duty and rest time rules, China Eastern will staff these flights with multiple sets of pilots and cabin crew. Airlines usually load extra meals and drinks in advance, but the Auckland stop will allow China Eastern to replenish supplies mid-journey if necessary. Singapore Airlines continues to hold the record for the longest nonstop flight — nearly 19 hours between New York and Singapore. Still, no other passenger service has attempted what China Eastern is about to offer: nearly 29 continuous hours on a single aircraft under one flight number.
