Not just Spain/France/Turkey - I've been vectored 90 deg off course inbound Scandi for Nationals 30 miles behind!
A few years ago, with a valid EuroC slot ex MAD, waiting for start with slot 'cancelled' by MAD ATC due to 'airfield restrictions'. Fortunately our ground eng spoke Spanish and had a feed from delivery, and only 1 in 10 non-Spanish a/c were getting start clearance (some on our route). I was the only BA a/c (out of 4 delayed) there with HF. Also as luck would have it, a phone patch went STRAIGHT to the BA ATC liaison man who just happened to be in Flow Control at Maastricht and the MAD SATCO had a right earful from Eurocontrol.
UK ATC plays it ABSOLUTELY straight, as does UK with all things Euro, unlike some! Wouldn't it be ?'fun'? to have, say, a week, where London plays the game differently - and see how it feels both professionally and commercially? Anyone up for it?
