This rate is valid seven days a week, based on sale seat availability, on trips completed on or before March 6, 2013. The low rate is also valid on trips started on or after April 8 and through May 15, 2013. The big bonus feature of this deal — no blackout dates.

• San Francisco, California: AirTran offers nonstop service to San Francisco at one-way rates of $109.80. Trips at this rate are permitted seven days a week (based on sale seat availability) through May 30, 2013. To qualify, give at least a one-week advance notice of travel.

• New York City-LaGuardia: One-way rates to the Big Apple of $126.80 require a 21-day or more advance notice of travel. This sale rate is valid seven days a week, based on sale seat availability.

These three airfare offers do not have a ticket-by date which indicates that they may vanish at anytime. Act quickly to make your purchase.

Sale airfares are always subject to change. Every seat on every flight is not offered at the lowest rate.
