For every photo with my lucky charm that you “like,” you’ll be entered for a chance to win. The contest will go until 5pm ET Sunday, and then we’ll announce the winner on Monday.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

See privacy policy.I know not everyone has joined Instagram, but it’s a great social media channel with the ability to share beautiful pictures not only on your Instagram feed, but also on Twitter, Facebook, Tumblr, Flickr and Foursquare so you can make all your friends jealous of your travels. Not only that, but more and more airline, hotel and credit card promotions are being staged on Instagram, so those not on it can miss out on some good opportunities.I’m not going to preach the virtues of Instagram, but I personally love it because it gives me so much travel inspiration seeing great photos from around the world. If you don’t have a phone that can install this free app, don’t worry - we’ll be holding more giveaways every Thursday here on the site so you can enter in the future.If you don’t win, remember that the British Airways Visa Signature Card from Chase is currently being offered with a sign-up bonus of 4 Avios for every $1 spent on all purchases within your first year up to $30,000 and a $95 annual fee, so you can rake in enough Avios to fly Aer Lingus roundtrip business class from the sign-up bonus alone.In the meantime, may the luck of the Irish be with you, and top o’ the mornin’ to ya!
