Old Translink publicity and aggregator pages promise Smartlink singles at £5. The operator's last published fare revision set the cash single at £9.00 from June 2024, and the airport's own fare table now shows £9.50 cash / £13.50 monthly return / £60 ten-journey, with £8.00 only on the mLink app. Budget to the current table, not the blog.
Legacy guides end the 300 at 'Europa Bus Centre'. Translink's airport pages now list the city-side stop as Belfast Grand Central Station, the hub that replaced Europa, with rail and coach connections under the same new roof — and its ticket machines now stand there instead.
Cash singles are £9.50 each — £19.00 round trip — while the £13.50 one-month return saves £5.50 if you fly back out of Belfast International. On mLink it is starker: £11.00 for the monthly return against two £8.00 singles.
No station at Aldergrove, never has been; the bus or a cab is the whole menu. And the official taxi ranks by terminal sample-fare board, not website, so a driver quoting 'the usual' means nothing until you see the number.
