I was advised this morning by KF agent (there was a memo) that AI is upgrading their system and they are not allowed to make any AI flight bookings, including commercial bookings. They could see award availability with AI but just can't book it. Apparently, this is the case since March this year. I did a follow up call later in the morning and the shift supervisor confirmed this information. Anyone made any AI flight bookings in the last 5 months or so?
