A new transportation services agreement to operate 10 Boeing 767 cargo jets for Amazon (NASDAQ: AMZN) paved the way for pilots at cargo airline ABX Air over the weekend to ratify an extension of their labor contract until 2030, company officials said Tuesday. Amazon's assignment of planes to ABX Air was also made possible by union leaders' more collaborative approach to jointly growing business after a history of tensions and a shortage of captains at sister airline Air Transport International, they said.

The agreement includes an option for Amazon to sublease 10 more aircraft to ATSG after 2024. Only four of the 40 B767 cargo jets currently flown by ATSG for Amazon are under the ABX brand.
