All flight and booking information in one place.
National Aviation Services just released their official mobile application on both iOS & Andoid, just look for NAS airports and you will find it in the store.
The app brings real time flight information, allows you to book an airport lounge or the meet and assist service or even check on your lost luggage and much more.
Other than that, you can complete your check-in or select your seat on your flight, plus you will receive local and global travel and duty free promotions.
The idea of how they are trying to put everything in one place is excellent, the app still needs some improvements in design and updates in different sections though.
