I spent 11 hrs in the back of an F9 Airbus a few years back. Could not get in to Denver so diverted to Colorado Springs. They had no gates there. One guy was toted off by medics after awhile. Could not handle being in the tube for long. Toilets backed up. They had to open the doors to allow fresh air in. After many hours on the ramp I asked an FA how about a hotel for the night. She actually said they had a schedule to keep. Then a tow bar could not be found to handle the bus since the bus did not operate there. Several of us offered to push the thing. Actually we were going to make a run for it if we got off. I think they sensed this in that our offer was refused. Eventually the weather cleared and we got to Denver. Not alot of fun people. Not at all.
