With no longer a London air route Air Astana has made life easier for UK originating passengers by introducing a Meet & Greet service at Frankfurt.  A similar operation is being established in Kazakhstan at Almaty and Nur-Sultan airports.

The new offering is intended to smooth the passenger journey through the airport, with effortless completion of mandatory procedures currently required for international travel.
 
In Almaty and Nur-Sultan, departure and arrival escorts will meet passengers at designated entrance and exit points within the terminal, with assistance provided for baggage handling, check-in and boarding. In Frankfurt, passengers using the transit service will be met by the escort at the aircraft door or entrance to the terminal, with expedited transfer procedures to the connecting flight for both passengers and their baggage. The fee for the Meet & Greet service is €40 per passenger at all three airports.

Air Astana is expected to return to Heathrow Spring 2022.
