I have two separate reservations to FTU as I intended to turn my visit to NY into a mileage run: One is STL-ORD-SFO-ORD-STL and the other SFO-ORD-LGA-ORD-SFO. Two different reservation and record locators. Family (health) issues may have me canceling my attendance to FTU. I know there is a $150 fee for canceling an AA ticket. Would it be possible for me to call to have combined those reservations and then if I were to cancel I would only have to pay once? Thanks.
