We had Manston change to London Manston a few years ago when it tried to re-brand, it can’t have been that succesful as its back to being good old Kent international Airport now. Near to 2 hours on the train to London, thats after a battered old bus took you to Ramsgate station(if it didn’t break down!)
Theres that old cliche in British films about american tourists thinking london was Englandand vice versa, i think airport operators are suffering the same confusion!
