Air Astana's first 787-9 enters flight testing ahead of 2027 service entry

Air Astana's first Boeing 787-9, registered EI-KZA, completed its first test flight on October 1, 2026, and is now in Boeing's factory flight-testing programme at Charleston, South Carolina, one of the manufacturer's 787 production sites. Delivery to the Kazakh flag carrier will follow once all certification procedures are complete, the airline said.

The aircraft is the first of three 787-9s that Air Astana plans to introduce into service in 2027. The type's arrival marks a milestone in the carrier's fleet modernization programme, according to the airline, which confirmed the test-flight start in a statement on October 22, 2026: "Air Astana's first Boeing 787-9 Dreamliner, registered EI-KZA, has begun its factory flight testing programme in Charleston, USA, where one of Boeing's manufacturing facilities is located. We look forward to welcoming our first Boeing 787-9 Dreamliner to Kazakhstan!"

What does the 787-9 change for Air Astana?

The answer, in the airline's own framing, is threefold. The 787-9s will gradually replace Air Astana's Boeing 767-300ER fleet on long-haul routes. The carrier asserted the new aircraft will improve operational efficiency. It also expects the type to create opportunities to expand its international network while maintaining high standards of passenger comfort.

Those claims align with the aircraft's role rather than with a schedule. The 767-300ER, the type being retired, is an older-generation widebody; replacing it with the 787-9 on long-haul sectors is a step-change in fuel burn and range capability for the routes the twin-aisle fleet flies. What is certified and flying at this stage, however, is only the airframe itself: EI-KZA remains a Boeing asset in test status until the certification procedures close and the handover occurs.

What is not yet defined is the commercial deployment. Air Astana has not announced which routes the 787-9s will serve. It has also not disclosed details of the cabin configuration. Route assignments, seating layout and entry-into-service dates therefore remain open items between now and the planned 2027 debut.

Timeline and delivery sequence

The sequence now under way is standard for a 787 delivery. The steps, as confirmed by the airline and the test activity in Charleston, are:

• First flight completed: October 1, 2026, from Boeing's Charleston facility.
• Factory flight testing: in progress as of the airline's October 22 statement.
• Certification procedures: must be completed before delivery.
• Delivery and service entry: planned within a programme that puts all three 787-9s into service in 2027.
• Fleet role: progressive replacement of the 767-300ER on long-haul routes.

The October 1 first flight, followed by an active test programme three weeks later, indicates the aircraft is moving through production flight testing on a normal cadence. The remaining gate between Charleston and Almaty is the completion of certification procedures, after which EI-KZA becomes the first Dreamliner registered in Kazakhstan.

For Air Astana, the stakes are operational as much as reputational. The carrier has tied the 787-9 to efficiency gains and international network growth, and the 2027 service-entry plan gives it roughly a year to convert a test airframe in South Carolina into a long-haul replacement for its aging 767s — with route and cabin announcements still to come before then.
