I posted several months ago regarding transportation from Glasgow to Edinburgh and received great replies about bus and train service. However, because of recent health issues within our group of 4, and possible disruptions to train service on that route in July due to construction, I've been looking into car or taxi service directly from Glasgow Airport (GLA) to Edinburgh. I received a quote of 156 GBP for return taxi service from OTS Taxi Service, which seems to service airports throughout the UK. Does anyone have any experience with this company as to whether it's reputable and reliable? Or do you have suggestions re any other car service?
This post on TA is old, so you might want to start your own post on either the Glasgow or Edinburgh forum in addition to waiting for a response here. I heard about the disruptions for the train and right now, the bus is probably the best option.
Also, I searched the visit Scotland site and came up with this list, which is slightly helpful.
If you don't hear anything, you might email them. Here's a link with the contact info.
Also, did you google, ground transportation Glasgow Airport? That brought up some more options.
