Greetings;

I suspect this question has been asked and answered many times, but I haven't been able find relevant information using FT Search or Google.

I have a mini-RTW from Europe 1 to Asia 1 with a stopover in Canada on the outbound. Just received an e-mail from AC advising of a significant schedule change ( 4.5 hours ) on an AC domestic flight in the middle of the itinerary.

Will a schedule change of this magnitude allow me to make changes or cancel the itinerary without charge ?

I am far from home at the moment and it will be somewhat challenging to call AP. So I would like to have a sense of what to expect before I make the call.

Thanks very much in advance.
