The info about not ticketing until 7 days out sounds strange to me--never had that experience.

I've mailed in a few vouchers before but usually prefer to go out to the airport and complete the entire process (paying with the voucher and ticketing, or paying with voucher and CC co-pay and ticketing) with an agent. I guess I don't trust US Postal enough when I can ride my bike out to the airstrip and have the TSA dudes wonder how I'm going to fly in Lycra and without a bike box.
