A Delta Air Lines flight from San Juan to Boston diverted to Bermuda for a medical emergency, then ran into a cascade of complications that stretched a four-hour flight into roughly 30 hours for passengers aboard.
The crew timed out after the diversion, according to a Delta spokesperson, triggering an overnight hotel stay in Bermuda. Passengers said they weren’t transferred to the hotel until around 3:00–3:30 a.m., and some reported being woken and bused back to the airport by 6:40 a.m.
The complication that followed was rooted in the flight’s domestic origin. Because the route from San Juan to Boston is domestic — Puerto Rico is a U.S. territory — most passengers had not brought passports. The diversion into Bermuda, a foreign country, changed that calculation entirely. When the flight eventually continued to Boston, passengers could not deplane for hours while customs sorted out documentation for travelers who had not expected to enter international airspace.
Passengers described the wait on the aircraft at Boston as poorly managed, with no apparent contingency in place before the plane landed. One traveler said agents “verified, reverified, and triple verified” citizenship status before allowing passengers through.
Delta issued a statement saying the safety of customers and crew “comes before all else” and thanked customers for their patience.
For crew, the event illustrates the operational chain reaction a diversion into foreign airspace can set off — particularly on domestic-origin flights where passengers hold no travel documents. Duty time limits ended the crew’s day in Bermuda, as they are required to, and a replacement crew was not described in available reporting. Customs processing at the destination fell to federal authorities, but coordination ahead of arrival was cited by multiple passengers as inadequate.
