"-- First-Checked-Bag Fee: The airline announced plans to implement a
first-checked-bag service fee of $15. The new fee goes into effect
for tickets booked on or after July 9, 2008, and will apply to all
flights within the U.S., to/from Canada, Latin America, and the
Caribbean. The airline will waive the fee for its most frequent
customers including: all Dividend Miles Preferred members (Silver,
Gold, Platinum and Chairman's Preferred), confirmed First Class
and Envoy passengers at time of check in, and Star Alliance Silver
and Gold status members. The following customers will also be
exempt from paying the fee: military personnel on active duty,
unaccompanied minors and passengers checking assistive devices."

Tickets bookd on or after July 9. Does that mean travel July 9 or make the reservation July 9?

So if I make a reservation today for travel on August 1, do I pay the baggage fee?
