Earlier this week, US Airways announced their 100% Share Miles bonus. Now through October 15, 2013, you’re able to share miles, and the person receiving them, will receive a 100% bonus.This week’s Thursday Giveaway is inspired by the Share Miles promotion.If you were to purchase miles, they normally cost 3.5 cents each plus a 7.5% tax, and sharing miles costs 1 cent each plus a $30 processing fee and 7.5% tax. The cost drops to just about 1.1 cents per new mile created via the bonus, since you are paying the share miles costs and fees, but generating twice the miles. For example, sharing 50,000 miles would cost you $567.50, and you’d be generating a bonus 50,000With that in mind, for this week’s Thursday Giveaway, I’m going to be sharing 13,000 of my US Airways miles, which means you’ll receive 26,000 US Airways miles into your account if you win.How to EnterIt’s simple – just leave a comment below telling me how you have helped someone in the past with miles and points, or how someone has helped you. It can be anything from getting a relative to a family reunion or event, or using your miles to bring your friends along on a fun vacation. It could be helping a random seatmate rebooking their flights on your iPad after an IROP so they wouldn’t misconnect, or giving your first class upgrade to a uniformed member of the military and how you went about it doing it. Whatever the scenario is, I want to hear!You have until 5pm ET on Monday, October 7, to enter. Then Team TPG will go through them and choose a winner and announce it next week. The winner must have a US Airways account that is at least 12 days old to participate (per the rules of the transfer bonus!). Only one entry per person will be permitted.And the Winner of the 25,000 Southwest Rapid Rewards Points Is…Last week’s giveaway was for 25,000 Rapid Rewards points.For last week’s Thursday Giveaway, I decided to reward one lucky reader with 25,000 Southwest Rapid Rewards points.
