Glad this was able to help some of you - wish I had something on the books to take advantage.. And feel free to send me half of what you would have spent on the fare differences as a finders fee.

I wonder if it’s also of some benefit to AS by not displaying / crediting back when there would be a decrease in fare? Assume not, and would be best to check with a dummy booking and simply cancel for credit instead of changing. Also curious if this applies to saver fares or only main / first..
