Both of these offers are set to expire on May 31, 2013. Last year, when PointsHound was offering free airline miles, the offers were retired early.
PointsHound is a service that awards you airline miles for hotel bookings. I have written about this service several time and you can access my latest piece here.
It is good to see PointsHound expanding its partner airline portfolio. If you have no use for Virgin America or Etihad miles, you can always sign up for the program using LoyaltyLobby’s sign up link here.
