My US Airways Dividend Miles award bookings that include travel on LH usually start with a US Express-operated segment from SYR to LGA, picking up LH at JFK or EWR. The leading US segment has never appeared online on LH.com or checkmytrip.com, but everything always works out fine when I check in with LH.

The final segment, from LGA back to SYR, does show up on LH.com. As a result, the LH agents in the FCT/FCL on the way home can usually check me in for both the LH flight and the US connecting flight back to SYR. (The only time they couldn't was when I had a pre-assigned exit row seat on the Dash-8.)

Happy travels,
David
