One familiar motto of the Iowa Lottery is “You can’t win if you don’t play.” Well, if you have played and you didn’t win, you now have a second chance. The Lottery is launching a promotion today that enables people to send in their non-winning scratch-off tickets for a chance at winning free airfare.Iowa Lottery spokeswoman Mary Neubauer says the “Million Mile Mail-In” gives people a shot at winning one-million frequent flier miles in a drawing to be held at the end of March. She says people have to send in two non-winning scratch-off tickets from the two, three or five-dollar game categories.Neubauer says the Iowan who wins the one-million frequent flier miles will be able to do a lot of flying.The deadline for entries is March 25th.
