That's the only safe assumption for anyone with privileged access. If your ‘mate’ wants to book a flight there are well publicised ways of doing so and there is no need to seek ‘inside’ information here. You do not get to decide for yourself which military information is and is not classified - if you had any type of security clearance you would know that.
