I'm sure the airlines update their products frequently to stay on top of the latest developments with the competition. EK and QR must be sleeping badly at night because EY stole all their F bling... hence the bloggers need to check out every product periodically? Just like the fruit in your pocket that has iOS 8.4 behaves differently from say iOS 8.1? Also, would you rather rad a review from 2013 or one from February 2015?
