thanks for all the input..but what ive gotten so far is that the rules are a little sticky...some posters are saying $100 while others are saying $50.

i guess there is no such thing as a refund...back to the credit card. I'll live with that fact i guess

FLYTHETAIL: I looked in the fare rules but it says nothing about what happens if there is a decrease in fare. ANd i did a search on the word decrease in the document too..

since i got a voucher already should i try and argue that it is a $50 admin fee and get the extra 50 in voucher's?

would it help any to say that this is an international itinerary...maybe the admin fees differ for domestic and international?
