Jet2 LS1750 Squawks 7700 and Diverts to Split With 165 Passengers on Board

Jet2 flight LS1750 from Samos to Manchester set the emergency transponder code 7700 and diverted to Split, Croatia, on Friday, October 30, 2026. Split Airport said the 165 passengers and six crew were all fine and that no one was hurt.

Croatian reports blame technical difficulties, but none of them names the fault. As of October 31, we found no statement from Jet2.

What happened on LS1750

The aircraft was a Boeing 737-800 registered G-JZBU, according to Flightradar24 data cited by N1. It was due into Manchester at 3:30 pm UTC.

Reports differ slightly on when it left Samos, both citing Flightradar24. The Chester Standard says 11:48 UTC, while Slovenia’s 24ur says 12:39 Central European Time, which is 11:39 UTC.

By 24ur’s reading of the track, the jet turned left toward Split about an hour and a half into the flight, at around the border between Croatia and Bosnia and Herzegovina. Flightradar24 posted on X that LS1750 was squawking 7700 and diverting to Split, as Morski reported.

Tracking data described by N1 showed several turns over the sea near Trogir and Split. At one point the aircraft was at about 2,300 feet (700 m) and 190 mph (306 km/h).

How Split Airport responded

The airport, also known as Sveti Jeronim, said Croatia’s air navigation service told it of the emergency landing at 14:20 local time, or 13:20 UTC. That was about two hours before the flight’s scheduled arrival in Manchester.

Under its emergency plan the airport began a full readiness procedure, with its own services and outside emergency services on standby, HRT reported. The reports we read describe those crews standing ready and do not say whether they were needed.

HRT said the aircraft landed safely. The procedure ended at 14:42, 22 minutes after the notice, and the airport said traffic was running normally again.

The exact landing time does not appear in any report we read. The airport’s count of 165 passengers and six crew makes 171 people on board, as Net.hr reported.

What is still unknown

The cause is the main gap. Morski said the fault had not been officially disclosed and that a more detailed inspection of the aircraft on the apron was expected, but we found no reported findings.

We also found no report of how the passengers continued to Manchester, or of whether G-JZBU has flown again.

What a 7700 squawk does and does not tell you

A transponder squawk is a four-digit code the crew sets for air traffic control, and 7700 is the international code for a general emergency. It highlights the aircraft on controllers’ screens and gets the flight priority, without the crew having to make a radio call first.

The code does not say what is wrong. In September a Pakistan International Airlines 777 squawked 7700 into Manchester because a child on board needed urgent medical care. The airline said the call was made for a passenger, not for the aircraft.

That is why the squawk and the phrase “technical difficulties” say little about how serious LS1750’s problem was. Several Croatian reports, Index among them, note that the code does not mean a jet is about to crash, only that the situation calls for urgent handling.

The turns near Split also have no reported explanation. Crews can hold to work through a problem before landing, and a diversion airport has to suit the aircraft and handle its passengers, but no report says why this crew flew that track or chose Split.
