On the long haul leg of the flight, you will be flying with Air Astana Business Class Airbus A321neo. The intimate business class cabin has just 16 seats across five rows, arranged in an alternating 2-2 and 1-1 pattern. Rows one, three and five are arranged in 2-2 pairs, though there is a divider down the middle for privacy. Rows two and four are arranged in a 1-1 configuration. These are the ‘throne seats’ for those looking for a space with no seat mate, as well as direct aisle access and extra privacy.

The ticket includes priority check-in, airport lounge access, business class meals, two pieces of checked in luggage, amenity kit, and wines, champagne and other beverages.
Even though you can probably save a few bucks by booking with some of the budget websites, we recommend booking directly with airline’s website to ensure better customer service post sales. Deals so good wouldn’t last. So, act fast!
