I spent some time trying to 'educate' the FBlue 'assistant' (having been cut off several times before - i really hate FBlue telephone assistance - btw).. that one could redeem with Malaysia Airlines...
after a few difficult exchanges (shall we say), she decided to actually check and then agreed that miles were indeed redeemable on MAS (LHR-KUL).. but there were no seats 'for weeks and weeks (?)'... so i was told..
i gave up...
will continue to fly on Star Alliance members...
