While planing/researching my next trip ... I wanted to get from ICN to KIX. To my surprise I couldnt actually find a JL flight from ICN to KIX. Then I looked around some more and found the following. JL5120 / JL5212 / JL5214 ... but surprise surprise those flights are actually KE flights (723/725/721) I'm not sure if those JL flights would be bookable ... since they're actually KE flights? Does anyone know? thanks!
Its pretty straight forward isnt it ? .....if the operating carrier is a not a partner of AA ...one cannot book awards or receive miles on paid tickets for that flight code-share or not.
Even more simple than that is the general rule that codeshare flights are not bookable as awards. There may be a couple exceptions out there somewhere, but that general rule is pretty solid.
Interestingly one of the exceptions is with AA miles. QF codeshare flights on JQ are bookable for awards.
