Terminal Night Closure
Asturias Airport is not open 24 hours and closes overnight, which means passengers cannot sleep inside the terminal. Following the departure or arrival of the day's final scheduled flight (generally between 1:00 am and 2:15 am depending on the season), security staff vacate and secure the terminal building.
Overnight Services and Alternatives
There are no 24-hour cafés, restaurants, or shops operating during the early morning hours, nor are there luggage storage rooms or dedicated overnight rest lounges. Doors reopen between 4:45 am and 5:00 am in time for morning flight check-in.
Travellers with early morning departures or late-night arrivals should arrange advance reservations at hotels in Santiago del Monte or nearby towns such as Castrillón or Avilés, arriving at the terminal once it reopens.
