After spending hours poring over lots of different routing for a United Mileage Plus saver award that would include travel on Star Alliance partners I've decided to give up.

The KVS tool indicated numerous flights on Lufthansa, Singapore and Thai with CS+ and YS+ availability but when speaking with UA 1P international reservations agents they were unable to see similar inventory in their system - and I spoke with multiple agents as well (all US based and not the off shore team).

I spent nearly an hour on the phone with one agent who was very kind and patient trying to help me build a successful saver award itinerary but we couldn't come up with anything that matched what I could find with the KVS tool. She indicated that maybe the system I was looking at (KVS is querying ANA?) had inventory from carriers for award travel that was not similarly shared with United / in the United system.

I'm not sure if this post really belongs here or may be better cross posted or moved to the UA MP forum.
