Once again, AC shoots itself in the foot.
Mine worked fine when it first came out on iphone and you couldn't book flights, only check schedules. Then they upgraded it and its not worked since.
The Aeroflot......um Aeroplan website still gives me problems from time to time as well. Its hard to redeem miles as it gives me some code in error, then you have to call in but they want a fee to process over the phone.
