Jet2 Boeing 737 Makes Emergency Landing at Faro After Crew Reports Cabin Smoke — All 141 Passengers Safe

A Jet2 Boeing 737-800 carrying 141 passengers made an emergency landing at Faro Airport on April 16 after the crew detected smoke in the cabin and declared a technical emergency. All passengers and crew disembarked safely, and no injuries were reported.

What Happened

Flight LS3643 departed Bournemouth, England, bound for Gran Canaria in Spain's Canary Islands. While transiting airspace over or near southern Portugal, the flight crew detected smoke in the cabin and immediately declared a technical emergency, requesting priority clearance to divert to Faro's international airport.

The aircraft touched down safely at 12:24 local time. Its original scheduled arrival at Las Palmas de Gran Canaria had been 14:10.

Airport operator ANA confirmed the safe landing. According to reports from Aviation A2Z, 95 emergency personnel supported by 41 vehicles were deployed to the runway as a precaution — standard protocol when an aircraft declares an in-flight emergency. The rapid mobilisation reflects Faro Airport's preparedness for such incidents, particularly during the busy spring travel season when the Algarve sees a sharp increase in inbound flights from the United Kingdom and northern Europe.

Aircraft Grounded for Inspection

The Boeing 737-800 has been grounded at Faro pending a full technical assessment to determine the source of the smoke. Cabin smoke events can stem from a range of causes, including electrical faults, air conditioning system malfunctions, engine bleed air contamination, or issues with the auxiliary power unit. Until engineers complete their inspection, the precise cause remains undetermined.

Passengers were assisted inside the terminal building. Jet2 typically arranges alternative transport or accommodation for passengers affected by diversions, though the airline had not issued a public statement at the time of publication.

A Pattern of Diversions

Today's incident is not the first time a Jet2 flight has diverted to Faro in recent months. In December 2025, a Jet2 flight from London Stansted to Fuerteventura diverted to Faro Airport under similar precautionary circumstances. In May 2025, a Jet2 service from Birmingham to Dalaman in Turkey diverted to Luxembourg after an in-flight issue.

Diversions are a routine part of aviation safety. Pilots are trained to land at the nearest suitable airport whenever a potential threat to passenger safety is identified, and cabin smoke — even when it turns out to have a benign cause — always warrants an immediate precautionary landing.

Faro's Role as a Diversion Airport

Faro Airport's position on the southern coast of Portugal makes it a frequent diversion destination for flights transiting between northern Europe and destinations in the Canary Islands, North Africa, and West Africa. Its runway is long enough to accommodate wide-body aircraft, and its emergency services maintain readiness year-round.

The airport handled approximately 10 million passengers in 2025, with the vast majority arriving on flights from the UK, Germany, the Netherlands, and Ireland. The spring and summer months see a significant increase in traffic as the Algarve's tourism season ramps up.

Today's incident caused no disruption to other scheduled arrivals and departures at Faro, according to airport authorities.

This report draws on confirmation from ANA Aeroportos and initial reporting by Aviation A2Z. It will be updated if Jet2 issues a formal statement.
