Beijing and Frankfurt airports launched an easy gateway for Air China passengers to travel between the two cities on Monday, offering passengers convenient services.

The gateway allows passengers flying Beijing-Frankfurt routes with Air China, China’s flagship carrier, to enjoy services in Beijing Capital International Airport and Frankfurt Airport, such as a separate check-in counter, special waiting area and luggage pick-up line.

Air China runs two Beijing-Frankfurt flights everyday.

In September, Air China, Beijing Capital International Airport and Frankfurt Airport signed a Memorandum of Understanding for cooperation to build an efficient gateway centered in Beijing and Frankfurt, linking domestic and European lines.

The gateway looks to simplify boarding procedures and reduce transfer time.

Beijing Capital International Airport, as the busiest airport in China with 9.44 million passengers flying in and out of the airport in 2016, links 147 destinations across the world.

Frankfurt Airport is one of the busiest airports in Europe and the world, with 6.08 million passengers traveling via the airport in 2016. The airport can link 247 destinations in 100 countries across the world.
