Earning miles after upgrading economy ticket to business
Dear all,
I’m sure it was asked before, but was not able to locate the answer
recently took a flight from IST to DFW, got upgraded using EP voucher in the airport from T class to C class
However I received ~3000 miles for this flight, it seems that C class was not taken into account.
Is it correct? for any reason I thought that upgraded tickets provide new class respective amount of miles
thank you in advance
