American Airlines has launched Project Olympus to retrofit its 20 Boeing 777-300ER aircraft. The program was confirmed on 2026-09-27.[^1]

Aeromexico will operate the Mexico City to Montego Bay route three times weekly. The carrier will use 166-seat Boeing 737 MAX 8 aircraft on the route, and tickets are already on sale.[^3]

Boeing identified a flight management software issue on the same date, affecting 737 MAX 7 and MAX 10 aircraft. The fault can disengage vertical navigation during specific missed approach sequences.[^2]

Additional operational filings from the period include a safe diversion of a Boeing 747-400 to Manchester Airport, passenger posted footage of galley water use on a Frontier Airlines flight, and a general flight status advisory issued by airport operator SAC.
