411A:
Apart from the relatively few DOMESTIC flights which are level-capped and therefore don't make it into RVSM airspace, have you stopped to think how many more DOMESTIC and INTERNATIONAL flights we are able to fit in at high level because we are using RVSM? I suggest that you, in one of your trips here from that side of the Pond, might feel the benefit when trying to return Stateside and RVSM means your delay is 20 mins instead of 1 hour. That is because of increased capacity brought about by RVSM.
As others have said: Your neck is getting a little extended. Try retracting it!
