I bought a ticket EWR-IST-TLV on Turkish J with United miles.
Last week I received a schedule change and new itinerary. At the same time, my mileage balance went up by the amount of miles I had paid for that ticket. When I look at the new ticket, it says method of payment: Miscellaneous Document, with a note at the bottom that says "remaining value of your previous ticket numbers xxxxxx was applied to this purchase". At this point in time, I have paid nothing but the taxes for the ticket.
Do I need to be concerned about the validity of the ticket itself?
Is it likely this gets picked up in some sort of audit of mileage balances?
