Look BOAC, Thunor asked, and gave this information: <<assuming you are neither employed by the airline in question nor "personally known to the Captain" nor a CAA Flight Ops. Inspector etc...>>. I told him quite truthfully and undeniably 'no chance'. I don't see what help it is trying to prove there is an exception (for ATC) when it doesn't apply in his case. Most of us know there is an exception for very limited cases- I don't think it helps him. So, the answer is 'no chance'! My glasses are just fine, thank you. I think it unlikely people will take a flight with a foreign carrier in the hope their slack interpretation of the rules will mean they may be able to sit upfront.
