The terminal building, erected in 1968, contains an arrivals room and a departure lounge, with a check-in desk for the airport's only scheduled airline, Aurigny.

Routes to other destinations such as Brighton, Bournemouth, Cherbourg, Exeter, Plymouth and Jersey were abandoned over the years due to what Blue Islands, for example, claimed was 'lack of interest'.

[citation needed] From September 2013, airline Aurigny operated direct flights to Jersey on a trial basis for a period of six weeks.

[citation needed] The States of Alderney put aside £400,000 from the £1m paid for a £12 million expansion of the airport proposed in 2019.

Aurigny Air Services Ltd also stated that the expansion would reduce their operating costs as they could remove the Dornier 228 from their fleet.

[10] In December 2022 the States of Guernsey agreed to spend £24m on extending, widening and strengthening the runway, construction of a new terminal building and refurbishment of the fire service facilities.

[11][12] It was reported in January 2023 that land acquisition to allow the runway extension and repositioning of the track to the west had already started.

It was also reported that tenders would be issued in the next few months, but work to secure Civil Aviation Authority and European Union Aviation Safety Agency approval for designs for the work would be needed, before issuing construction tenders.
