Thanks for your continuing help. Please can I play back my understanding of the Canadian Exception.

I have setup an online itinerary starting out in Sudan for the cheap price. It comes to $2788+taxes. Because the first flight is on RJ I won't he able to book on line. I am in London UK.

If I then call AAs RTW team they will charge me the price for starting from the UK and I will lose the advantage of the low price for starting from Sudan. However if I ask them to set it up for it to be ticketed in Canada I will pay in C$ the equivalent of $2788+taxes. Correct? Is Naseem the agent to use in Canada?

Finally, if my credit card details do magically work online on the AA website, will I be charged the $2708+taxes or the London based price.

I have my Sudanese visa and I am good to go!
