NEW YORK- Fort Worth-based American Airlines (AA) flight AA20 from Dallas Fort Worth International Airport (DFW) to London Heathrow (LHR) was diverted to New York’s John F. Kennedy International Airport (JFK) on August 24, 2025.
As per the latest available schedule, American Airlines operates five daily flights between two industrial cities, i.e, Dallas and London.

According to FlightRadar24 data, American Airlines flight AA20 took off from Dallas (DFW) at 23:08 UTC. The flight was originally scheduled to arrive at London Heathrow (LHR) at 09:00 local time.
After being airborne for over two hours, the pilots informed those onboard that the aircraft’s GPS, required for safe oceanic navigation, was not functioning correctly.
Instead of crossing the Atlantic, the aircraft diverted east and entered a holding pattern before making its approach into John F. Kennedy International Airport (JFK).
The crew determined that continuing across the North Atlantic without primary navigation would pose unnecessary risk and therefore opted to divert. The flight ultimately landed safely at JFK.

The Boeing 777 is equipped with multiple redundant navigation systems, including GPS and Inertial Reference Systems (IRS).
While the IRS can provide navigation support even without GPS input, crews generally prefer GPS precision for long overwater segments. On this flight, the crew relied on backup navigation systems before deciding to reroute to New York.
A recording from live air traffic control indicated that the decision to divert was coordinated with controllers as the aircraft was over northeastern U.S. airspace. Aviation enthusiasts tracking the flight also observed the unusual holding patterns before the aircraft redirected to JFK.

An American Airlines Boeing 777-200 operating flight AA333 from Athens (ATH) to New York John F. Kennedy (JFK) diverted to Bangor International Airport (BGR) after the crew detected a fuel imbalance, which led to the shutdown of one engine.
The aircraft, powered by Rolls-Royce Trent 800 engines, landed safely in Bangor (BGR). Inspections later confirmed a mechanical fault, and the aircraft was cleared for service after repairs.
Flight AA333 was en route from Athens International Airport (ATH) to New York John F. Kennedy International Airport (JFK) at cruising altitude FL380 when the flight crew identified a fuel imbalance. At the time, the aircraft was about 290 nautical miles southeast of Bangor International Airport (BGR).
Following standard operational checklists, the crew shut down the right Rolls-Royce Trent 800 engine. The aircraft proceeded under single-engine operation and landed without incident on Runway 16 at Bangor (BGR) approximately one hour after the issue was detected.
A report from the Transportation Safety Board of Canada (TSB) confirmed the cause of the fuel imbalance. Maintenance teams discovered a broken fuel tube in the right engine, which triggered the imbalance and required the precautionary shutdown.
