The original LAS-TYR itinerary would not have had me wait so long between flights. Since our office closed early I was able to leave earlier. I wanted to take advantage of that to have extra time with family at Christmas.

When I changed to the earlier flight I had already decided to rent a car and drive the last leg instead of waiting for the first fight from IAH to TYR. If I had been aware of this cancelling the remaining itinerary I would have waited for my original flight.
