Question 1

Is Belfast International the same as Belfast City Airport?

Accepted Answer

No — Belfast keeps two separate airports, and mixing them up is expensive. Belfast International (BFS) is this one: out at Aldergrove, 18 miles north-west of the city, and the larger by far — 6.68 million passengers in 2025 against 2.36 million at George Best Belfast City (BHD) in the CAA’s table. Check the three-letter code on your booking before you set off; the two sites are not close to each other.

Question 2

How do I get from Belfast International Airport into the city?

Accepted Answer

Translink’s Airport Express 300 picks up at the front of the terminal and serves Belfast Grand Central Station and Queen Street, with a ticket machine at the stop. At weekday peaks a bus goes every 15 minutes, and the timetable never really stops: overnight departures continue hour by hour, every day of the week. The 300a variant also calls at the Templepatrick park-and-ride.

Question 3

Can I take a train to Belfast International Airport?

Accepted Answer

Not directly — no railway line touches the airport. Two workarounds exist: ride the 300 into Belfast Grand Central, the hub of the NI Railways network, or use the Ulsterbus 109A, which meets the trains at Antrim (the buscentre is next door to the station) and at Lisburn. Coming from stations on the Derry~Londonderry line, a £2.20 Airlink add-on ticket, sold by train conductors and bus drivers, covers the airport bus leg.

Question 4

What are the security rules for liquids at Belfast International?

Accepted Answer

The airport has finished its scanner upgrade, so the old 100 ml routine is gone: individual containers can hold up to 2 litres and nothing — liquids, laptops, phones — needs to leave your hand luggage; plastic bags are not used at all. Frozen liquids and frozen food remain barred from the cabin, and metal drinks bottles should go through empty. Coming home, the rules of the departure airport apply, so check them before you pack.

Question 5

How much does it cost to drop off or pick up at Belfast International?

Accepted Answer

The Drop Off Zone directly opposite the terminal charges £5 for 10 minutes, paid at the coin or card machine on exit, and the car must never be left unattended. Two cheaper routes: the Long Stay car park grants a 15-minute grace period at no charge, and Blue Badge holders can take up to 30 minutes free in the Short Stay by pressing the help button at the exit for validation.

Question 6

How early should I arrive at Belfast International for my flight?

Accepted Answer

The airport advises being in the terminal two hours before departure — three for transatlantic flights, whose desks open that far out. Check-in desks close between 40 and 60 minutes before the scheduled time depending on the airline, and security will accept passengers from six hours ahead, so an early arrival with a Causeway Lounge booking (entry from 2 h 30 min before the flight) is a workable plan.
