Thank you for the help airoli. The ticket is issued by LX. Actually the original flight to ZRH was on AC YYZ-ZRH but AC cancelled the flight. Neither airline notified me and it was only when I looked in EF for the seat map that I realized something had changed. Dealing with LX's callcentre in Capetown while pleasant it seemed I knew more about what to do as far as changing the ticket than they did originally. That is why I thought I would ask here for advice just so I have some idea what options I have if AC has more industrial action the day of my flight and I have to contact LX again. I enjoyed my last LX flight in J from YUL-ZRH and back so the flight change was actually a bonus even with the extra leg.
