I seam to be missing something here. CAP371 has been around longer than most of our jobs. The CAA requirement is 90 mins. I presume this is based on min rest (say 12 hrs) minus up to 3 hrs travelling = 8 hrs - a normal nights sleep. Breakfast etc is normally provided on the flight so no need for meals at home. Most of all you job contract specifies a base. All in all a normal safe and happy situation. If you over 90 mins away without a rest place closer then you are violating all the safety measures put in place to protect yourselves and everyone around you. If there is an incident because of tiredness you are to blame.
If companies acted in this way the tread would be 10 times longer than this. Selective reading of the Ops manual and CAP371 doesn't work - either by the company or the pilot / Cabin Crew.
