Incident Overview
• Date: January 20th, 2025
• Aircraft: Boeing 737-800
• Registration: G-JZBV
• Operator: Jet2.com
• Flight Number: LS-135
• Route: Glasgow (UK) to Rome Fiumicino (Italy)
• Outcome: Safe diversion to London Stansted
Summary of Events
Jet2 flight LS-135, operated by a Boeing 737-800 (registration G-JZBV), was enroute at FL370 near Paris when the crew observed unexpectedly low fuel readings. Exercising caution, they decided to turn around and divert to London Stansted. The aircraft landed safely on runway 22 approximately 40 minutes after the decision to divert. Emergency services inspected the aircraft but found no fuel leaks or other visible issues.
A replacement aircraft, also a Boeing 737-800 (registration G-JZDG), was dispatched to continue the flight, which reached Rome with a delay of approximately 3 hours.
