Hi,
I've created the following itinerary
https://goo.gl/flights/hJJ2
Ideally I'd like to UuA the outbound LHR>ORD from J to F. The AA price comes in a fair bit cheaper than the BA one but I think I am right in saying that the rules changed regarding codeshare and UuA a while ago?
Can someone please confirm that I've understood things correctly and that my options are:
1. I need to pay the extra £164 and book on BA and then pay whatever else on top (miles/taxes etc).
2. Book on AA for the cheaper fare but lose the option to upgrade to F.
Thanks,
Contractor
