Glasgow as a city really has been sliding backwards. The once bussling Buchanan Galleries is looking to be closed and access to the airport is choked via the M8. I find the airport really easy to use, security usually top notch and a plethora of airbridge served stands and space to sit. But from being the UK's 4th / 5th busiest airport in the 90s, the relative decline is obvious now. It's back to core outbound sun routes, Loganair and a truncated UK domestic network with some loyal oldies like KLM and Icelandair. Lufthansa, who knows? So sad.
The growth of Edinburgh really has smacked Glasgow into the shade, it's now like Manchester, inbound attractions just don't sell it.
