It has today been revealed that as of October 1, 2020, United Airlines will be closing crew bases in Frankfurt, Hong Kong, and Tokyo, impacting 840 employees. This means the only remaining foreign crew base for the airline will be in London.
United Airlines has flight attendants based in four foreign cities — Frankfurt, Hong Kong, London, and Tokyo. These crews don’t operate domestic flights within the US, but rather typically just operate flights to & from their home airports.
Those eligible to work in the US will be allowed to transfer bases, though understandably many of them may not want to move their lives to the other side of the world. Then there are also all the employees not eligible to work in the US.
