Thanks - Delta did give me a 6-alpha PNR supposedly for KoreanAir (not 8-digit), and on Korean website putting that in shows some message to the effect that it can't be viewed online call our reservations.

I'll check Saudia and try to get an 8-digit PNR also, thanks for the pointers.

Update: Saudia air does show all segments (SEA - LAX - ICN - KIX), with message Fare Basis: CSM700/FFO21 and Fare Status: Paid and Coupon Status: Open (LAX segment) /Airport Control (other segments). SEA DL X/LAX KE X/SEL KE OSA0.00CSM700/FFO21 USD0.00END XT 8.80BP 1.80YQ 5.60AY 17.70US
