Terminal
Ibiza has a single passenger terminal building, completed in 1973 on the site of the original Es Codolà airfield. Aena’s own airline finder confirms it: of the 42 airlines with scheduled flights, none is split across a second terminal — the finder’s alternate "NT" filter has no scheduled carrier assigned to it.
All 42 scheduled airlines check passengers in through the same terminal building — there is no split by carrier or by flight to plan around.
Fast Lane priority security access is bookable and, unlike most airports, runs 24 hours rather than daytime-only hours.
Barrier-Free assistance can be booked online, by app or by phone at least 48 hours ahead; the booking line runs 7:00–00:00. Aena specifically tells passengers on early-morning departures to check the terminal’s own opening times before planning their arrival.
