How Likely Are Chase Ultimate Rewards Transfers to Delta or American? by View From The Wing. Just can’t see it happening to Delta, American Express would have that locked away tighter than anything I’d imagine. American Airlines would be a possibility and if Citi passed on the ability for their TYP to transfer then that would be a big hit for them. This would be huge for Chase if they were able to secure either. I haven’t heard of anything, so I’m doubtful this is in the works but happy to be proven wrong.
