One more thing....

A lot of people don't know this, but my parents used to use up all of those 24 one ways. On top of those you get either 4 or 6 round trips (I forget) on American Connection. As long as you don't touch an Eagle or AA flight you can connect on them and it all counts as one leg.

Example: CID-STL-JAX is one leg and taking the same flights back would be one round trip. However if you take AA from JAX-STL on the way home it eats up one of the 24 passes.

Throw in some ID90s and you've got some busy retirees for parents. Not to mention they give more leeway on those loans from flight school.
