When I tried to explain that we had already paid the pet fee, United said that it didn't matter since we had two carriers...
Note to self - if flying with Pet make sure no codeshare flights.
IMHO you have absolutely nothing to lose writing to US and demanding a credit for the second fee. You would have a valid argument as it was a US ticket for both flights. @:-)
