Bus 915 is the direct link from Glasgow Airport to Greenock
McGill's 915 runs from Glasgow Airport (Terminal 1 bus stance) out toward Greenock and Inverclyde, so you skip a detour into Glasgow city centre. The route connects the airport to Paisley, Port Glasgow, and Greenock on a single ticket, which is useful if your final stop is along the lower Clyde rather than in the city itself.
The 915 operates daily, with services running roughly every 60 minutes during daytime, though exact headways vary by weekday and weekend timetables. First departures typically start in the early morning and continue into the evening, so late-night arrivals after 23:00 may need a taxi instead. Always check the latest McGill's timetable on the day you fly, as seasonal tweaks hit this route.
The stop at Glasgow Airport sits a short walk outside Terminal 1, next to the other local bus stands serving routes into Paisley and Glasgow. Signage for McGill's is visible at the bus stance, and the stop flag usually shows "915" toward Greenock and Inverclyde. You do not go through any extra security to access the stop since it is landside, before the departure hall doors.
Single fares on McGill's 915 run in the region of £6–£9 depending on distance, with day and zone tickets available if you are continuing beyond Greenock or doing same-day returns. Drivers accept contactless bank cards and most UK transport smartcards, and you can also buy mobile tickets in the McGill's app before you reach the stance. Keep a few pound coins as backup in case the card reader has issues on a specific bus.
The 915 calls at key points such as Paisley, Port Glasgow, and central Greenock, which helps if your hotel sits near the A8 or close to Greenock town centre. The run from the airport to Greenock usually takes about 50–70 minutes depending on traffic around the M8 and A8, so build at least an hour into your post-landing schedule. If you have a rail connection from Greenock Central, check ScotRail times and give yourself a 20-minute buffer between the scheduled bus arrival and your train.
One practical tip: if your flight lands around 17:00 on a weekday, assume peak traffic on the M8 toward Greenock and aim for the first 915 you can physically reach, rather than waiting 60 minutes for the next service. That simple move can save you 20–30 minutes and keep you on time for evening check-in in Inverclyde.
