I have MSY-DFW-BOS-SNN (turn around)-BOS-ORD-MSY for Oct. 28 with Oct. 29 return for my mileage run, and for up front in the 757s. What are my choices? My first choice is simply move it back to Oct.23-24 without any flight changes. Do I have to pay any fees? Because of mileage desires, I would like to keep Boston in the picture, so my second choice is Aer Lingus
to Shannon since it is a code-share. My third choice is MSY-ORD-SNN-ORD-Msy for obvious reasons. How do I approach the plat. desk to change my ticket?
