I wanted to seek some clarification. I recently travelled on UA, and noticed that my mileage had not been credited to my account. I contacted TG Ticketing office, and was advised that W class on UA was not eligible for mileage credit. I find this a bit strange, as when I purchased the ticket the agent told me that this fare class was eligible for mileage credit, and also confirmed this on the UA website.
TG advised that this was not correct, as it would be for TG to decide as to which fare class would be eligible for mileage credits.
I am confused now, I thought that there was a common agreement amongst all Star Alliance carriers as to which fare classes will be eligible for mileage credit. Can someone help clarify this?
