From LBA there is a direct train sprinter service to Glasgow Central in the summer period only, at least there has been for the past few years? It takes around 4 hours I gather from my Glasgow based, Leeds colleague.
Other than that you can catch a GNER service via Edinburgh or hop across to Preston or Wigan and catch a Virgin west coast service also to Glasgow Central. From Glasgow Central you’d change to a Paisley Gilmour Street local service (10 mins ) and catch the airport bus outside which will take you to GLA in 5 mins.
Thanks for the info Ren 🙂 Worth bearing in mind in the future, but just realised its not the school hols anyway then, wouldn’t be able to make it. Another thing you’ve got to remember is the train service wouldn’t be from LBA (As it doesen’t have a train station!) But from Leeds Central. A bit longer to travel than the bus to LBA at the top of my road!
