Heres the deal.

Thinking of a mixed-carrier trip in May.

OKA-ICN-PEK on Asiana
PEK-KIX-OKA on ANA (w/ Air-China code-share).

Through both ANA and Asiana sites, it's hard to pull that up.

UA website on the other hand can pull it up quite easily.

I am still evaluating all my ticketing options (all through ANA maybe), but if I were to ticket this, is doing it through UA a good option? What do some of you do in similar situations?
