Don't know the answer.does that mean you can use miles from Jet Blue on AA and vice versa?
I think that makes it great for the customer. I had thought you could only do that if the flights showed up on the other carriers website. For example, I didn't think I could use Delta miles for an Air France flight unless that particular Air France flight shows up on a search on the Delta website and thus even though I'm technically booking an Air France flight I am doing it through Delta. I assumed this would work the same way. I wonder if they have an interface that allows you to apply your miles from the other carrier through your log in or if they will just have all flights show up on both websites. For me this is great because I have "some" JB miles and "some" AA miles.From the link I posted: " Travelers can also earn and burn frequent flyer miles with flights on either carrier."
