My tickets are for May. to position I need to decide if I am flying out of MCO on United or MLB with AA or DL. We will go the day before and if we go MCO I can get direct to ORD, out of MLB we will have a stop in ATL or CTL. I'd rather stop in ATL.
Like everyone else I have no idea what I should sign up with to credit these miles. I did fly with Turkish last year but I don't see the miles in my account there from those flights and the website is a nightmare. I don't think I can collected them from United if I wasn't signed up at the time with them. Ideally if I can get status with this then I would want to get it matched to DL since that's my usual.

Any advice on how to do that is welcome.
