Today I was deplaned for a MX. I walked up to the gate agent and was told they couldn't rebook me because of the new system. I was sent to the next flight that was leaving and told they should be able to put me on the plane. On the walk to the next gate I had the 1k desk book me and when I arrived at the next gate I said "I was moved to this flight, can you please print my boarding pass" where it was all booked and ready to go. I hate this "the system won't let me...." answer I keep getting.
