MUC-FRA-BOM in Y/E upgrade with evoucher again confused the system: distance based on FRA-BOM, but only 240 miles for the FRA MUC.
Return DEL-ZRH-MUC in D credited 8784 miles for the longhaul segment and 372 on the short hop.
In the end 15519 miles for a ticket that cost me 2077€+370€YQ+taxes and should have earned me 14682 miles
