another "enhancement" I just experienced is that they do not let me (DM) take a bassinet seat anymore (without an infant, in J), even when all bassinet seats are empty now AND I'm completely ok with giving up the seat if there's really a need in the end (i.e. all other infant seats occupied by infants in the end, which I don't expect will happen in the next few days since we're flying this weekend). otherwise my family have seats all scattered around in the cabin now, and they still gave me super hard time releasing one of the infant seats to me so that we could sit together. in the past they're quite happy doing it for DM. but now again claimed that it's a "feature" in the new system and they can't do it anymore.
another new feature of the new system seems to be...in the old system, redemption booking booked using my miles can be viewed on my "summary" page plus can be viewed in the detailed page...but now they are only shown on my "summary" page and once I clicked on it, it said it cannot be shown because of some system error or something. some MPO supervisor also just confirmed it's a new "feature" of the new system.
plus every time when I called, almost every agent keep on saying "oh system hangs again", "system is slow", etc every few minutes...yesterday it took me like an hour doing some award refund plus a redemption booking...and today another 30 mins just messing around with the seat arrangement of one flight.
too bad I still have some 500-600k miles expiring EACH year for the next few years...but starting from now will indeed make sure not to put too much more miles into AM anymore...can't completely avoid, of course...but cannot put all eggs into one basket that's breaking down...
