Ok here are the flights I was looking at, and the fare class that it books me in.
15 June MSP-ORD UA 1246 -- C
15 June ORD-FRA UA 940 -- C
16 June FRA-CPH LH 3026 -- C (2-3 seating shown Euro business)
20 June CPH-LHR UA 9387 -- C
22 June LHR-ORD UA 959 -- B (seat mapper shows C class seating)
22 June ORD-MSP UA 1660 -- (none, nothing shows, and seat mapper puts in back of bus)
This is why I am really confused.
