My wife received a mailed statement after waitlisting for a mileage upgrade (intl copay + miles)..

Statement reported the underlying ticket price & taxes in GBP and USD; the miles; but not the additional taxes or copay. Also, towards the bottom, the currencies switched... i.e:

Fare 400 GBP = 650 USD <not real #s>
Taxes...

etc...

Total: 400 USD (should be GBP).

Online, the #'s are correct (but attempting to view the receipt generates an error). The #'s online don't however, include the copay.
