I wish they would consider pushing the envelope a little bit for their top tier fliers, as it would help all of us even those that don't fly F9.
Some benefits that would get my attention are:
1. Allow you to confirm at no charge same-day time changes on restricted tickets if the same fare class is available.
2. Relax capacity controls for award travel ticketed more than 30 days in advance to take inventory from the highest non-refundable fare code, not the normal stingiest award code.
3. Southwest's "Companion Pass" idea - fly 100 segments, and somebody travels free with you for a year.
