Or you could be in the camp that says LOA is an allowance that has been going up an down like a whores drawers since it's introduction and that to have planned a whole 3 year tour based on the rate set on day 1 is pretty naive at best.
We spent a total of 7 years over 2 tours in receipt of it and never knew from one month to the next what we would get due to FFR changes and reviews. Accordingly we never once factored it into our accounts planning as it was never meant to do anything but supplement my pay.
Just a thought but LOA at a rate of £17 a day is over £500 a month on top of someones annual salary which however you look at it is hardly going to put anyone in the poor house.
