I'm on a paid Comfort W and W+ fare in early June. GSP-DTW-LHR outbound and FCO-ATL-GSP coming back. Can I use miles to upgrade to Delta One? Anyone have a read on what a fair amount will be if it is possible?
UPDATE: I called and there was no upgradable inventory. I'd have to rebook to a Main Cabin Upgradable fare (about $200 difference) and then she quoted 65K miles each way. But I'd be waitlisted and she said she had no idea if they'd open any inventory since it's in June, peak season etc. Ugh.
She suggested I call back later to see if inventory has opened up. Anyone know how far out those decisions are made? Thanks.
