For complicated original routing credit requests like this, I suggest faxing the request (404-773-1945). Include a cover page with a brief explanation of the situation and outline exactly what dates, flight numbers, routes, and approximate number of miles you are requesting for each leg. Include copies of all receipts, itineraries, boarding passes, etc. for your original journey and what you actually flew. This is the best way to make your case and provide all of the supporting materials necessary at once, something that can't be accomplished by phone or through the online mileage request. Good luck...I suspect you'll get the outcome you want.
