Pin,
Not everyone on flyertalk is a frequent flyer. Many people "earned"
these free tickets through thousands of dollars of credit card
transactions. They deserve to know definitively what is in their
account.
No reason to withhold this info from passengers, except that it is
in SWA's best interest if they don't have to provide the free ticket
and can sell a seat instead.
I suggest everyone ask if they have any expired tickets IF they
are going over their account at the 1-800. We live in a fast paced
world.....
