Apologies if this is something more obvious to the more knowledgeable, but after many years of flying I find myself in a situation which hasn't arisen before.

Only ever flown UA or AS and the miles go to my FF account with those airlines. Had a trip booked in business with UA to Manchester UK, but they kept changing the schedule until the connections were just to tight a time. I cancelled the UA flight and for the first time in many years of flying TATL booked a flight with DL. When booking I put in my AS FF details, but wanted to ask that I'm understanding correctly that DL will credit my AS FF account with the miles for this trip. Like I said never been in the situation of flying on one airline and getting miles credited to a partner airlines program before, so wanted to check my understanding is correct. Thanks.
