Long Haul flights

[nordjet415]

Hi all.

I am not cabin crew and simply have an interest in aviation.

I am soon travelling from Manchester to Manila ( Philippines ) with Qatar Airways Via Doha, I am just curious, could someone please tell me how often the cabin crew visit the cockpit on say a 9 hour flight ?

I assume there must be some kind of rule that cabin crew either speak via phone or visit the flight deck just for example to make sure they are not asleep ?

No I am not a nervous flier, its just that its my first long haul flight and I was interested to know what the rule is on this.

Finally, has anyone used Qatar Airways and if so, what are they like ?

Thanks to anyone who replies.

Regards
