Belfast International has a single, two-level terminal with one airside lounge, free WiFi for 2 hours, a quiet room near check-in and a Changing Places toilet by Gate 18, but no left-luggage storage anywhere on site. Checked August 2026.
Airport lounges
The Causeway Lounge is the airport's only lounge, sited airside in the main terminal after security and open to any passenger who wants to pay for it, not just premium ticket holders. It costs £27.50 for an adult and £15 for a child aged 2 to 17, with under-twos free. You can pay in advance online or at the door, though the door rate depends on space being available. Inside there is high-speed WiFi, power outlets, a TV and comfortable seating. It opens around 05:00 and closes around 20:00, so it is not an option for late-evening or overnight departures. Fast Track security is not included in the lounge price and has to be bought separately.
WiFi, charging and workspaces
Free WiFi is available in the main departure areas for up to 2 hours, which comfortably covers most connection times before boarding. Charging points are provided around the terminal, including in the food and shopping areas, so you do not need lounge access just to top up a phone or laptop before a flight.
Food, drink and shopping
The terminal has a mix of bars, restaurants and cafés, including a Burger King, alongside the usual airport retail. Seating is spread through the departures area near the food outlets, and water refill stations are available if you would rather not buy bottled water after security.
Left luggage and lockers
There is no left-luggage storage or lockers at Belfast International. If you need to store bags for a long layover or an early arrival before check-in opens, you will need to arrange this off-airport in advance, since the terminal only handles lost and found, not deposit storage. Lost property itself is managed by the OCS Lost Property team; recovering an item carries a £5 admin fee and items are held for a maximum of 30 days.
Special assistance and accessibility
Special assistance for reduced mobility should be booked through your airline in advance, and the airport advises arriving in good time on the day. Many airlines ask for at least 48 hours' notice for special assistance, though you should confirm the exact window with your airline when you book, since it varies by carrier. A Changing Places toilet, with the extra space and equipment that standard accessible toilets do not have, is located to the right of Gate 18 in the departures area. Belfast International supports the Hidden Disabilities Sunflower scheme for passengers with non-visible disabilities, and recognised assistance dogs are welcome throughout the terminal.
Travelling with children and families
Baby changing facilities are spread through the terminal: on the departures concourse between Burger King and the children's play area, near Gates 10 to 14, in the ground-floor arrivals hall, at the top of the moving walkway, and in the international departure lounge. A children's play area is also available in departures, useful if you are killing time before a flight with younger passengers.
Prayer and multi-faith rooms, quiet spaces
There is a multi-faith quiet room near check-in for prayer or reflection. It has been temporarily closed at times in the past, so it is worth checking locally on the day if this matters to your journey.
Smoking and vaping
Smoking is permitted only in designated outdoor smoking areas outside the terminal; there is no smoking anywhere inside the building. There is no separately published vaping policy, so it is sensible to treat e-cigarettes the same way and use the same outdoor areas.
Security fast-track and how early to arrive
Belfast International's new security hall, opened as part of a £100m redevelopment, uses CT scanners that have lifted the old 100ml liquids limit: you can carry liquids, gels and aerosols up to 2 litres and leave them, along with laptops and other electronics, inside your bag rather than removing them for screening. Fast Track priority security passes cost from about £5 per person and are bought separately from lounge access. The airport advises arriving 2 hours before a standard departure, with transatlantic check-in desks opening 3 hours before departure; check-in generally closes 40 to 60 minutes before the flight. Security waits are typically under 15 to 20 minutes.
