Europe’s cargo airports are outperforming its ocean container ports.

Frankfurt airport, Europe’s largest air cargo hub, saw traffic decrease 2.6 percent year-over-year in 2015, mirroring declines at third- and fourth-ranked Amsterdam Schiphol and London Heathrow.

One of the world’s largest air cargo handler Worldwide Flight Services has announced plans to acquire a majority stake in the German Fraport Cargo Services, further expanding its reach into the European market.

Frankfurt airport handled 6.4 percent less freight in March than a year ago as strikes by Lufthansa pilots resulted in the cancellation of intercontinental flights.

Lufthansa Cargo is “cautiously optimistic” about its performance in 2015 after filling nearly 70 percent of its capacity in a fiercely competitive market last year, CEO Peter Greber said.

Air freight operators have almost completed their shift of capacity back into China following the Lunar New Year celebrations.

In July, Fraport Group’s five majority-owned airports handled 179,500 metric tons of cargo, a drop of 0.6 percent from July 2012.

Fraport, which operates Frankfurt Airport in Germany, handled 174,047 metric tons of cargo, including transit, in April, sliding 0.1 percent from April 2012.

From January to March, Fraport Group’s five majority-owned airports handled 555,737 metric tons of cargo, an increase of 1.7 percent year-over-year.
