Southwest Airlines will operate its remaining Boeing 737 Classics on their last flights today, as it prepares to deploy the 737 Max on revenue service on 1 October.

The Dallas-based carrier's final 737-300 flight will operate from Houston Hobby to Dallas Love Field tonight, arriving at 23:35.

Registered N632SW, the 737-300 was delivered to Southwest in 1996, Flight Fleets Analyzer shows. The jet sustained damage in a 2011 pressurisation incident and returned to operations later that year.

The aircraft is among more than 30 737-300s in Southwest's fleet that will be phased out after today. They are mostly in the 20-year-old or so age range, Flight Fleets Analyzer shows.

Southwest, which took delivery of its first 737 Max 8 in August, will debut nine 737 Max aircraft in revenue service on 1 October. The first 737 Max-operated route will mirror the final 737-300 flight, departing Dallas Love Field at 07:00 for Houston Hobby.

The route is similar to Southwest’s very first flight back on 18 June 1971 - except that the airline operated 737-200s then and had flown to Houston Intercontinental instead of Hobby.

Southwest, the world's largest 737 operator, has orders for 200 737 Max aircraft, comprising 170 Max 8s and 30 Max 7s.
