Hi,

I'm trying to book the following itinerary: ORD-MRS-LON-FRA-ORD. I'd like the ORD-MRS leg to be on BA and the FRA-ORD leg to be on UA/LH, but booking the one-way flights on each carrier separately produces absurdly high fares - more than booking the entire itinerary on 1 carrier. Is there a way to get this to work without paying through the nose for one-way tickets on BA and UA/LH separately?

[The MRS-LON leg is best on BA, while the LON-FRA leg could be done via train if need be.]

thanks for any advice you may have
