Virgin: 20% off flights through Feb. 15 with promo code.

Planning to travel this winter? You can get a discount code from Virgin America and save 20% off your flight. The first 50,000 to sign up will be emailed a promo code, which you can apply to a flight between now and Feb. 15 (I'm assuming the holidays are blackout dates, even if they weren't already full).

Avoid the holiday travel craziness and go in January when things quiet down — and get cheap.
