"Both Colin (outbound from Airport) and Graeme (inbound to airport) were excellent - very friendly, professional, on time - which was challenging for Colin as our flight into Glasgow was delayed by 2.5 hours due to weather at Luton (snow and ice), but he text me that he would monitor the flights and still meet us at the terminal.
We also had to change our return flight (due to the delay) as was a business day trip and Colin made sure that all the arrangements were made for this later return.
Excellent service, much cheaper than using Airport Taxis and I would absolutely recommend using their service (Scottish Transfers)."
