DUBXH - whoops! In vino dyslexitas unfortunately.
jabird - interesting point on the intl waters but aren't flights to places like Greece dereg-ed even though they pass over non-EU states...
no, no, no - I don't believe you can operate one flight a week - it would depend on the bilateral with Barbados. The Shannon lobby would ensure that 1/week would have to stop.
The problem is that SNN (EINN) seems to have been written into all the bilaterals. If bilaterals don't apply because the endpoint is an fully constituted part of the EU for deregulated air route purposes then any bilateral should have no force - you would think.
