The limit has been $1,500 since the first commit of the policy in 2012.
Inflation and other economic forces have brought us to the point that
international travelers routinely show us searches where the cheapest fare
is around or over $1,400. Increase the limit to try to level the number of
flights requiring preapproval.
This was always our intention. However, the previous wording didn't account
for gaps in the time that advance purchases (especially flights and other
long haul travel) are made and the time the travel actually occurs. This
updates the wording to match our intention.
* Introduce a "Rates" section that's referred to throughout.
* Explain how the total M&IE allowance is calculated.
* Update the info about currency conversions to explain we now use Open
Exchange Rates based on the date of the reimbursement request.
