Jetblue (B6) and Japan Airlines (JL) reached a codeshare agreement for 21 US destinations from B6’s stronghold cities of New York and Boston. JAL had direct flights from both cities to Tokyo. The codeshare strengthens the interline agreement that they had established in February.
It is interesting to note that none of the 21 destinations are currently served directly by JAL’s Oneworld partner American Airlines (AA). That is not surprising given the strong ties B6 has with AA. Last November, AA announced the ability to each AA miles on select B6 routes and vice versa.
Unfortunately, you cannot yet redeem AA miles on B6 at the moment. Am I being absurdly optimistic in guessing that reciprocal miles redemption ability may be coming soon?
