Thanks
Has Iberia cancelled any of the other African cities to Madrid flights as well?
I have been chatting with American Airlines and now have a supervisor who is functioning as a single point-of-contact with the AA Liaison Desk. She said that they currently do not have "protection" in place (another Oneworld carrier picking the ticket up) but the AA Liaison Desk is working towards that end and hopes to have this by Monday (the AA Liaison Desk does not work weekends). I let her know that an "involuntary refund" would be disastrous ($10,000 in lost tours, $10,000+ in consulting contracts I have given up, etc.) and she said that is not even being considered. I told her that I have flexibility in that my tour ends in Livingstone on the 29th and my next tour begins on June 2nd in Marrakesh.
So, for now, I will wait and see what American Airlines comes up with as a solution and go from there.
Thanks again for all of your help.
