The plane had a mechanical problem. They had to find another plane as a replacement. The replacement flew to Boston, where it too had a mechanical problem, and needed to be replaced. So they were expecting that one to leave MCO at 10:30pm instead of 6:05pm.
I requested an overnight at MCO, since I was traveling with DD 4 and DD 6, instead of and overnight at DFW. We were scheduled to arrive at DFW around 1:45am, then would need to get a hotel room, and be ready to fly out of DFW by 7:35am.
My flight out of MCO the next morning was also delayed. Once again causing me to miss my connection.
I did finally get home via Delta. It was 22 hours after ME dropped me off at MCO.
