My GF is flying SFO-AMS-EDI on 23 Mar returning EDI-AMS-MSP-SFO on 31 Mar. On nwa.com, the SFO-AMS leg (actually KL 606) leg doesn't show up in the itinerary, but all others do. The first leg DOES show up on klm.com.

Anyone seen this oddity before? The reason I ask is that I was going to try to surprise her by upgrading the fare to B, and then using miles for WBC upgrade, but I can't do it online, since it can't find the first leg.
