Hi

I have a round trip from LAX-SFO-ICN-HKG, booked through korean air website directly. the flights between SFO and LAX are run by delta, SFO and ICN run by Korean air but also code share with Delta. the ICN and HKG are by korean air alone.

Since my first departure flight is through Delta, i received itinerary info from them for checking in. However I noticed that instead of LAX-SFO-ICN-HKG-ICN-SFO-LAX, it shows only LAX-SFO-ICN-HKG, then ICN-SFO-LAX.

So the first segment of the return itinerary (run by korean air alone) is missing from Delta website. But it still shows fine with KoreanAir website. korean air has issued all the e-tickets as well, and that missing flight even shows up on the receipt on Delta website, just not on Delta itinerary.

Is this normal or should I be concerned about?

Thanks
