Southwest Airlines plans to cut four seasonal markets by June 2012 and eliminate Reno-San Jose permanently.
The carrier disclosed the changes in a 3 October update to its corporate blog, explaining it had extended its current schedule through 1 June next year.
In total, Southwest stated roughly 50 markets will see changes with 24 gaining a slight increase in service and 19 recording a decrease in frequencies.
Four markets operated on a seasonal basis- Fort Lauderdale-Manchester, New Hampshire; Fort Myers to Long Island and Nashville; and San Diego to St. Louis - will be eliminated from the June schedule.
All of those markets are operated by Southwest Airlines. In May of this year Southwest acquired AirTran Airways, and currently the two carriers aim to achieve a single operating certificate from the US Federal Aviation Administration by 1 March 2012.
Since the close of the acquisition Southwest has revealed plans to cut some markets operated by AirTran with its smaller Boeing 717 aircraft.
Southwest stated it plans to unveil its summer schedule on 14 November.
