Unlimited space available for you, your spouse, parents and children. You also have buddy passes to give to others. We fly to a lot of cities, but not with any frequency and not with an obvious route structure. This becomes painfully obvious when you try to non rev somewhere specific. I once gave a buddy pass to a family friend, and he his only option to go from DTW to LAX was via MCO. If he didn't get a seat on the MCO flight, he was screwed for days.
Basically, don't non rev on us unless you're only going one leg to a city we regularly serve. A lot of our destinations are only served 3 or 4 days per week.
ZED fares are limited. American is the best one we have. We're missing Delta and United.
