Q. In checking the rules and restrictions on some of the fares you post, I notice that many include a 330-day travel period. What exactly does that mean?

A. Legacy carriers sell fares for travel up to 330 days into the future, whereas the newbie low cost ("low cost") carriers do not. For example, the current 330-day period allows for bookings through April of 2015.

This is especially helpful for those who plan to book using frequent flier miles, when booking early means better availability of award seats.
