I hate flying. Well I hate the thought of it, the build up, the waiting around and the actual take off and landing. Its the control aspect I think bothers most people. You having to trust in and hand over that control to the flight crew for the duration and all that. Once I am up there its a case of deal with it and get on with things as normal. And I usually do that just fine.
I only ever begin to relax once we have levelled out and are at cruising altitude. Then I tend to feel a bit better. Also I always figure if the cabin crew are carrying on a normal so I should be aswell.
I've done long haul so many times now and after the first few hours you do tend to forget you are on the plane in a simple kind of way. You are aware of it but your senses have dulled to it I think is how I'd describe it. I always ensure we take the night flight to Aus from London via Singapore and being tired and needing to snooze also helps pass a chunk of hours for me.
