10 US Airways or Delta Miles for free, 12 Starwood Points for free

US Airways and Delta Airlines offer 10 Miles bundled with 10 ShowPoints for free when you answer five trivia questions. (You'll need to register your rewards accounts with Audience Rewards to sign in, and ShowPoints can be redeemed for Broadway tickets and upgrades.) While we have seen much higher points giveaways from both airlines, this is the first offer we've seen for both airlines without any other memberships or conditions attached. (We saw 2,500 Delta miles for free after sign up to a new Netflix account in September. We also saw 500 US Airway miles for free when you downloaded and purchased something through its Dividend Miles StoreFront Shopping Assistant in August.)

Of note, for its Starwood Preferred Guests, Starwood Hotels & Resorts offers 10 Starpoints bundled with 10 ShowPoints for free when you answer the same trivia questions. That's the first Starpoints offer we've seen in several months, although we saw 100 points for free when you liked the Starwood Facebook page in May. (We also saw 10,000 points for free with sign up to the Starwood Preferred Guest Amex Credit Card in September.)
