Dallas-based Southwest seeks to bend its schedule to fit seasonal demand.
The airline's new schedule, announced today, covers flights from Jan. 9 to March 12.
Southwest will cut one flight per day on 92 routes and increase service on 42 routes -- usually by one trip per day as well.
Southwest also will suspend service between Albuquerque, N.M., and Portland, Ore.; and between Manchester, N.H., and Phoenix, with flights resuming in February.
Flights between Kansas City and Seattle will stop in January and resume in May.
