Here's a rather nice Promotion that I came across only just now. Which is a shame, because this promotion started nearly 3 weeks back, and is due to end in another 10 days. Nonetheless, it caught my attention because I do love reading, and this promotion fuels that interest of mine (even if I won't be flying Air Asia any time soon, because of my schedules).
During the promotion period (25 July to 25 August 2016), Air Asia is handing out Kindle devices for in-flight reading, in partnership with Amazon. These are, of course, returnable.
