The Army and Navy are not on the allowances yet they are still using old rates for RPOD and RILOR and GYH(P). However, they are nowe having actuals paid on their 1771's/C30's.
In respect of actuals LOA is now payable for ALL trips away providing an LOA area was visited. the list of areas is extensive. In order to claim LOA you are required to submit your detachment (or telporary assignment!!) to your HR Admin when you return who will action to JPA. An example of how much this can attract is a 5 day trip to the USA is around £80 for a Flt Lt. However these detachments need to be submitted to HR within 3 months of the start of the trip else JPA will not allow it to be actioned.
So all them trips that you have taken since mid april submit them to your PSF's and get some extra cash, this is one element of JPA that does work...
