Note-because of the merger with Alaska Airlines, the Virgin America Elevate Program will end on January 1, 2018
Virgin America has began offering a Plans Change Pass for $25 up that you can purchase
to 24 hours of departure time per itinerary. This pass will allow you to change your flight (an unlimited number of times) and just pay the fare difference instead of the flight change fees (which usually range between $100-$150).
Note, the Plans Change Pass cannot be used on Elevate reward flights or Elevate partner redemption bookings.
