The last few days, ever since the HA move to a new GDS on the 18th, it seems to be impossible to book any (award) HA flights on aa.com. The HA inventory shows and can be selected, but when proceeding to the next stop (cc input page), it always errors out saying "not available anymore," though it again keeps showing up in search, and is, of course, available. In other words, AA shows correct HA inventory, but fails to actually save it to a PNR for ticketing.

Has anyone been able to book any HA flights via AA since April 18th? Are there any known workarounds this problem?
