I will be flying a very convoluted run in Feb:

CPH-FRA-YUL-FLL: with SK CPH-FRA and AC FRA-YUL-FLL

the route home is:

FLL-CLT with US and CLT-MUC-CPH with LH. (no stopovers, just lots of legs...)

My question is how I will be received at check-in at FLL? Will US honor my *g status since the majority of the trip is *A (and the inbound flights were all *A) or will I get stuffed having to pay for bags and all the rest since US is (now) OneWorld?

I have been scouring the web to find the rules for mixed alliance flights, to no avail...

Thanks in advance!
