This may be Delta 101 but I cannot find anywhere the fare rules for what I think is my refundable ticket. I bought a refundable ticket SEA-PVR and in a week's time the fare has dropped twice ( $375/$250) ....saving us $600 a ticket. I want to make sure that the last change I made I stayed in the right class. ( right now it shows " I" class). Is there a way to recall the fare rules for the current ticket I hold or someway to confirm that it is refundable fare? ( it shows "refundable" during the booking process but not on the final ticket receipt or the " my Trips" webpage). Thanks.
