Using Delta SkyMiles to Upgrade on International Flights: The Definitive Thread
I purchased a ticket to LGW and used my miles to upgrade. When at CTO, the agent took my miles out of my account apparently when I had to make an initial change to the ticket. Subsequently, I have had to cancel the trip and DL will not redeposit my miles back into my account. I have been told that the miles will follow my credit and as long as I purchase a future upgradable fare, I can upgrade automatically. Is there anyway to get those miles back?
