First time posting, so, please be gentle.
Question...Should I have been entitled to the Delta, SPG benefits when travelling? I have contacted Marriott, SPG, Delta and Virgin and all have said that they cannot answer, it's up to Marriott, SPG, Delta or Virgin to define...
I rarely travel to the US and have Platinum status through trips to China, I linked my Marriott Rewards account when they merged with SPG and recently had to fly to the US on a ticket booked direct with Delta, which ended up being a code share with Virgin.
Interested tntic get your views on this as the back and forth to the US may become regular in future.
