The route

1,093 km (679 miles) great-circle, measured between the two airports' published coordinates. The line is the shortest path over the globe, which on a flat map bows away from a straight line.

27 sightings

Boeing 737-900ER (B739) in 44% of 27 observations; also Boeing 737 MAX 9 (B39M), Boeing 737-800 (B738).
