Following the Chicago seminars I have decided that instead of a planned trip to the OMA, I'd like to go to LAX FTU. Unfortunately I have already made 2 one-way reservation on AA to OMA (had 2 CITI AA card statement credits so had to book this way to get fully "free" flight. I've heard/read that if there are flight changes it is possible after a call to get tickets canceled at no cost. Fortunately my OMA-ORD_LGA flight has been changed, layover in ORD is 45 minutes later and return to LGA is 5 minutes later overall. When I tried calling and stating i wanted to meet someone in ORD which is no longer possible because of the change the agent told me sorry but there's nothing I can do... Does anyone have advice of how i should approach my next attempt at the phone call? Keep in mind that only my return flight had the change so not only do i want to cancel that, i'd like to cancel my outbound as well even though it is 2 separate itineraries. Thanks in advance!
