I have a question about award availability for elites with the new system:

With CO, there were certain economy award seats open only to elites, listed as XN fare class.

With the new system, all my award searches are showing as XN - even when using a non-elite UA account. Shows as "United Economy (XN)"

How do I tell if a certain seat is an elite only available seat? (other than checking availability with two accounts). I'm trying to book award seats using multiple family member accounts - would be very helpful.
thanks
