Oddly enough, I did have miles posted on an ON segment, except that it was an award ticket! Perhaps their system wouldn't be quite so messed up if they'd come up with a completely new set of codes, requiring a fresh look at any software that touches them, rather than shoe-horning all kinds of new stuff into their old set. With their hodgepodge of subsystems dealing with various aspects of reservations and tickets, as well as the rather confusing set of codes (including those like ON with double-meanings), there are likely coding errors all over the place that will be quite difficult to track down.
