Roaming has its disadvantages as well and today is bloody expensive......often in the past GF pilots nackered by the summer schedules stayed in Bahrain for their leave to relax and recover their sleep deficit and basically rewind their time zone base.
...no hassle with staff travel tickets...no hassle with space available on flights...no hassle with space available on return flights... no possible hassle with any Tax man... more valuable one on one relax time for you with your family in accommodation you have already paid through the nose for...time to get your teeth cleaned and any dental work done..
and lead a more normal life for a few days before the GF madness started again to rerack your life.
