Just got an email yesterday:
Use promo code "10OFF" to save $10 on each flight!
Instructions: Book a flight for travel from January 7, 2014 through March 12, 2014 and you'll get $10 off*. PLUS, you can combine this coupon with our Day of Week Deals for additional savings! Simply enter 10OFF (all caps, no spaces) in the Promotion Code box on the home page when booking to get these savings. Book today! All flights must be booked by 11:59pm on December 25, 2013.
Fine Print: Coupon only applies to the flight portion of a vacation package. To receive $10 off* your roundtrip purchase, you must enter 10OFF (all caps, no spaces) in the promotion code box on the homepage when booking your flight. Once the promotional code is entered, fares displayed will automatically reflect a promotional discount of $10 off* when purchasing a roundtrip reservation. Please note that the coupon applies towards "Our Price" shown on the Flight Availability page, but does not apply to the Passenger Usage Fee (up to $16.99 each way) or DOT Unintended Consequences Fee ($2.00 each way) which are included in the Base Fare. Additional terms apply. Baggage charges may apply.
