[QUOTE=mahasamatman;15762194]"Considerable lattitude" does not equate to "unlimited changes". One thing you can definitely do if your change exceeds two hours is cancel with no fees and rebook the future flight, but there are limits to the changes you can get.
I think you're trying to tell me that I'm asking too much, but it's this "limit" that I'm trying to identify since UA is not explicit about it.
