The parts people get wrong. Each one links to where we checked it.
Easy to get wrong
The airport's own page names no line and says only that the bus runs "depending on flight programme". The line number, S4, and an actual timetable are published by the regional transport authority instead.

Hours
The S4 runs from 07:20 to 22:30, at roughly forty-minute intervals, and reaches the bus station ten minutes after leaving the airport. Nothing runs before or after those hours.

Easy to get wrong
The long-distance coaches to Bilbao, Oviedo, Gijón and Laredo do call at the airport, but only for passengers who bought a ticket in advance. Turning up hoping to board one does not work.
