Sort of deviating but on a similar thread - when guys get a clearance from Gander for the eastbound clearance, the clearance is to EXPECT FL XXX from ABC.
What really riles me is the number of people who obviously go transatlantic each night but can't remember what is required for the readback, they say 'cleared FL XXX'.
It usually takes 2 transmissions to rectify the problem which takes ages.
Pay Attention folks
