Not that I'm panicking (actually I am slightly as I need to travel on the date I have booked) but I am due to fly DME-MAD-SCL in December (DME-MAD on IB / MAD-SCL on LA) should IB go ahead with their planned strikes in December, can anyone advise me how I should deal with this? i.e. calling AA to rebook on BA via LHR or AY via HEL? I assume that no reissuing fee will be charged?

Thanks in advance
