Hi! I know that doing a mileage upgrade award on a Virgin Atlantic flight is pending availability of a G fare on delta.com, then booking into a YMBW fare on DL.
But does anyone know if there's any correlation between G availability on Virgin Atlantic's site and Delta's? Years ago, I think the advice was if something pops up on VS's site, then it would likely be available soon on DL's. Is that still true?
