Looks like to get us upgraded I have to get us split onto a new PNR, but if I do that my other companions booked into MCE will lose their seat assignments or have to pay for MCE. Makes sense I guess since I won't be with them anymore, just a bit annoying to have to choose between letting my companions keep their seats or taking an upgrade. I don't even really need the F, it's more for 1 companion in particular who is a large guy and would greatly benefit from that extra space.
