Bargain of the Week

AirTran has launched a fall fare sale. The fares, from $39 to $99 each way, are good for travel through Dec. 16. Tickets must be purchased by tomorrow. Sample one-way fares from Washington Dulles: $59 to Atlanta; $69 to Orlando and Tampa; and $99 to Dallas. A seven-day advance purchase is required.

Fares, which were researched Thursday, may change without notice, do not apply to all seats on all flights and are subject to restrictions. Most require advance purchase, are available only on midweek departures and require a Saturday night stay. Certain airport taxes and surcharges are not included. Contact airlines or a travel agent for fare details and airports of arrival and departure.
