If you're a regular flyer with Air Berlin then you definitely want to grab the latest version of the airline's iPhone application. Besides a complete redesign that makes some other airlines apps look tired by comparison, Air Berlin has added support for Pebble with the release of version 3.0. And that means you can get your boarding passes on your watch.
Air Berlin isn't the first airline to try smartwatch boarding passes, and we sure hope it won't be the last. To make use of the new feature you need to have both the iPhone application installed and a Pebble specific app which is available in the Pebble app store.
I'll actually be flying with Air Berlin this weekend, so you can bet that I'll be trying this out. I'm looking forward to seeing how it goes!
