after I quoted Mwenenzi oneworld fare rules 2a, twitter team told me "We had just got clarification regarding the change fee, if you keep your stopovers the same, there is no change fee. For example, EZE to MIA to YYZ remains the same, the travel date is different, there is no fee. " I assume that's some good progress.

Another issue came up though: I want to change this EZE via MIA to YYZ from June 6th to June 1st and QF told me no availitbity. those two flights are operated and marketed by AA, I can see they still exist but maybe for a different fare code? I have to get to USA for some work on June 3rd so I wonder if they can adjust it to EZE - MIA on June 1st, then MIA-YYZ on a later date in June. But that's considered a transit to a stopover right? I asked if I can do EZE via JFK to YYZ they said "If you were wanting to change EZE to JKF then to YYZ, there would be a charge of the USD 125.00 and any fare difference is payable". thoughts on this one? thank you again
