oneworld
AAdvantage prices partner awards on a fixed region-to-region chart, so the connection costs no extra miles. Qatar Airways's CCJ–DOH nonstop is what makes Kozhikode a oneworld city at all, but Qatar Airways does not itself fly DOH–Taipei — so no waypoint beyond DOH is named here rather than invented. A valid oneworld routing onward from the DOH gateway on partner metal is assumed.
