I've must have tried every possible button the KE site, but it appears there is no way to add a PNR if you did not book with KE directly.

I have 2 trip seperate (Orbitz and Expedia) PNRs with a total of 6 segments all on KE but there is no way to bring them up.

Is the only way to get seat assignments to call-in to KE? What about walking up to my local airports KE ticket desk, could I get them to bring it up and get seat assignments that way?
