I'm on a *A RTW, UA issued, which has me routing IAD-MUC (UA) with a 35 minute connection (apparently legal)to make a VIE connection (Lufthansa operated by Austrian). Will I have to collect bags in MUC or will they interline thru to VIE? I'm worried about missing this connection, if I do who do I see UA, LH or Austrian?

TIA
