Southwest Airlines has announced discounts of up to 40 percent on some fares through mid-February.
Dallas-based Southwest on Tuesday kicked off the 72-hour air fare sale meant to attract travelers during non-holiday periods.
Southwest says the discounted fares exclude Sunday travel.
The fares are available for certain flights from Nov. 28 through Dec. 12 and from Jan. 7 through Feb. 14, with blackout dates for select markets.
The discount code BigDeal40 is required to attain the sale fares. Other restrictions may apply.
