Delta has announced sale fares between select cities in the U.S. Fares are $99-$199 each way, based on a round-trip purchase.
As an example of the savings, I priced a flight between San Diego and Las Vegas using dates allowed in the fare sale and received a quote of $184 round trip. A quote for the same flights traveling three days after the last allowed travel date in this offer priced out at $320 round trip.
Additional fees, restrictions, and baggage charges may apply. Tickets must be purchased by February 13, and travel must be completed between February 27 and April 9, 2014. The trip must include a Saturday night stay. There are no blackout dates.
Tickets must be purchased at least 21 days prior to departure. Tickets may be purchased at delta.com. Additional fees apply if purchased from Delta over the phone or at a Delta ticket counter or ticket office.
