New figures from Sea-Tac Airport show September passenger traffic was down just .2 percent from the record levels of September 2008.
Those passenger traffic numbers came in spite of fewer daily flights and fewer available passenger seats.
That trend to fewer flights is a result of airlines trimming excess capacity in the face of less robust demand for seats during the recession.
In October, the airport is reporting 406 daily departures compared with 428 daily during October last year. Average daily available seats are 51,993 compared with 57,233 in October 2008.
Planes are operating closer to capacity because of the fewer flights. The percentage of seats filled in September was 4.2 percent points higher in September this year than in September 2008.
Although the number of daily flights declined, the number of non-stop destinations increased from 80 in October 2008 to 87 this year.
