Terminal Information – Departing

Both of Belfast's airports only have one terminal, so that's one less thing to worry about.

From Belfast International: The departure lounge has free Wi-Fi throughout, so you can check your social media accounts or get a bit of work done before you fly. Shops include an Aelia Duty Free store, a Discover Belfast souvenir shop, a WH Smith and a Superdrug. If you're in need of refreshment you can grab a beer and watch the footie in the Lagan Bar, enjoy a quick snack at Burger King, indulge in a quick pick-me-up at Caffe Ritazza and Starbucks, or have a slap up meal at Fed and Watered while watching the planes take off. If you need a bit of extra luxury you can check into the business lounge, which is available up to two hours before your flight's scheduled departure time.

From Belfast City: The departure lounge is small but perfectly formed. You can do a bit of shopping at World Duty Free, House of Ireland or WH Smith. If you're peckish you can grab a sandwich at O'Briens, a coffee and cake at Costa, or something more filling at Harvest Market. Wi-Fi is available throughout the terminal, perfect if you want to check out our Dublin city guide before you arrive.
