To celebrate their newest destination of Philadelphia starting on April 4, 2012, Virgin America is running a Facebook promotion where you can enter to win free flights on the new route, passes to their Ultimate Tailgate party, and two-night hotel stays. Also, just for entering, Virgin America will send you a promo code good for 20% off your next flight between April 4 and June 15, 2012.
This offer ends on March 28, 2012, and your booking must be completed by April 30, 2012. Tickets require advance purchase of three days. Blackout dates are May 25 and May 28, 2012. Promo code is only valid for nonstop or connecting travel (not multi-city itineraries) on non-refundable Main Cabin tickets in fare classes S, L, M, U, E, H, B, or V.
