The Causeway Lounge is Belfast International's only lounge, airside after security, costing £27.50 for an adult and £15 for a child aged 2 to 17, with under-twos free. It includes WiFi, power outlets, a TV and seating, but not Fast Track security, and it closes around 20:00. Checked August 2026.
What the Causeway Lounge is
Belfast International has a single lounge, the Causeway Lounge, located airside in the main terminal once you are through security. Unlike some airport lounges, it is not restricted to premium ticket holders or a particular airline's frequent flyers; anyone can pay to get in, subject to space being available. You can book in advance online or pay at the door, though pre-booking is the more reliable route if you want to guarantee a seat, particularly at busy times.
What's included, and what isn't
Inside, the lounge offers high-speed WiFi, power outlets at seating, a TV, and comfortable seating away from the general departures concourse. What it does not include is Fast Track security. That is a separate product entirely, priced from about £5 per person, so if you want both a fast route through security and lounge access afterwards, you are paying for two things, not one.

When the price makes sense
The lounge is most worth it if your flight is delayed and you would otherwise be sitting in the general departures area for an extended period, if you have a genuinely early or long wait before boarding and want a quieter space to work or relax, or if you are travelling as a couple or solo and value having guaranteed seating with power for a laptop or phone. Because security waits at Belfast International are typically under 15 to 20 minutes thanks to the airport's 2025 security hall upgrade, you are not paying for a fast route through security, that is a separate consideration entirely; you are paying for what happens after you clear it.
When it's harder to justify
The maths changes quickly for a family or group. Two adults and two children would pay £27.50 plus £27.50 plus £15 plus £15, which adds up fast against a short-haul fare, especially on a budget airline ticket where the lounge price can be a large share of what you paid to fly. The lounge also closes around 20:00, so it is simply not available if your flight departs in the late evening or overnight, a real limitation given how many early-morning and late departures Belfast International handles. If your connection through security is quick anyway, and you are happy sitting in the main departures area near the food outlets, the £27.50 is a comfort purchase rather than a necessity.
How to decide
Ask yourself three things: is your flight during the lounge's roughly 05:00 to 20:00 opening hours, do you have enough of a wait before boarding to actually use the space, and are you travelling in a small enough group that the total cost stays reasonable. If the answer to all three is yes, the lounge is a straightforward way to spend a wait more comfortably. If your flight is very early or very late, or you are travelling as a larger family, the standard departures area, which has its own seating, charging points and a Burger King among the food options, may serve you just as well. More on the wider terminal, including WiFi and seating outside the lounge, is on the facilities page.
