Here's a new one. I had my brother-in-law and sister-in-law booked SEZ-ADD-(LFW)-IAH in C. I was checking on seating assignments for them on the ADD-IAH sector and noticed it said that the flight left at 8:30 in the morning. When I pulled up the itinerary on united.com, it showed that flight left at 21:30. So, essentially there was a schedule change and ET hadn't notified UA so I never got an alert. This was going to make them misconnect. So, I scrambled for options, found two saver seats on ADD-LHR and then I called UA and they were nice enough to open up C space on LHR-DEN-IAH.

Their final destination is actually SLC, but I couldn't get the agent to change the destination because it was over 1,000 miles away from IAH (new one for me). I asked if she could just change the final destination to DEN then, and then she told me it couldn't be over 500 miles away. Not sure why the policy changed in those 30 seconds. Either way, I'll just have them collect their luggage in DEN (if they check any) and then no-show for the IAH flight. My apologies for anyone flying on the flight that they're not taking as they have two seats in First booked.
