Ok BigBru, you have your own opinion but it doesn't mean that everyone must agree with what you wrote. If you really believe that business class seats for long haul flights are required to improve aviation safety, beside a horizontal rest, that’s right…it’s your point of view. But I’ve been crossing several time zones every month, and in my opinion I don’t believe they are an important safety issue, so what’s the problem? Just because there are different opinions about this matter you don’t need to treat everyone as child. Come on guy, several messages are posted here daily and divergences are usual…well, I suppose.
And about fatigue, what is your opinion about 2 cargo drivers who fly all night long with many stops during short segments without space and time to rest?
