Bengals311 has got the wrong assumptions. I thought I'd spare the details to save time and space, but here you go:

The company I work for gives all expats a "vacation allowance" which is a sum of money dedicated to pay for a flight back to our home country. The manual states that it should be equal to: "a full-fare, economy class, round-trip air ticket, as quoted by IATA".

The issue is that they used to calculate it by getting the one-way IATA full-fare and multiplying by two. Now they said the rules have changed and that a round-trip, as the manual says, is what should be used.

BTW, there are a few types of Y fares with restrictions, that not necessarily are 'full fare'. For instance, I have two quotes now, from the same airline, both Y fares, same day, same flight, return ticket. The only difference is the minimum and maximum stay. One is 4530 the other is 8898... Which one is the full fare, given both are Y fares?

Anyway, that is the situation. I'm trying to get what I believe is fair for my allowance, that's all.

Hope I can achieve that through this site...

Thanks!
