While over the Pacific on my first of 3 segments, I was bumped from my original 2nd flight to another 2 hours later.

My 3rd flight leaves at the the scheduled time still so my final arrival time is the same.

But the issue is, I had an important errand to run outside IAH which I cant do now due to having 2 hours less connection time at IAH

I booked this itinerary for a reason

Any suggestions what I can do about this?
