And we weren't only pax in situation - saw at least one at CS desk and talked to a couple more on the later flight.

So, anecdote - not sure this system worked as it should have - IAH-DCA flight arrived early anyway (10 mins) - and UA could have saved itself a hassle for at least a half-dozen pax who had to be rebooked/rerouted and inconvenienced.
