It is, generally, preferable to use ITN/AX access method as the ITN/UA method tends to show UA flights even when they were not requested.
However, sometimes using ITN/UA access will display classes that ITN/AX does not.

That is correct.

You can use smiley67's tool for that. The link should be somewhere in this thread.
