Hi,

I'm trying to book a flight on Expedia. I'm pretty sure it will not be issued by AC, but there is a domestic leg with AC flight number. That leg will be booked in S class. Since it is not booked by AC fare, I don't know which requirement will be applied to upgrade (such as Basic, Standard, Flex, etc.)

Does anyone have this experience before? I personally think it will be counted as Standard

Cheers
