SkyService
The link between SkyService and MYT is not clearly defined, and is not easy to determine. (Could be an inheritance from the dodgy ex-management now residing in their mansions in the North-West of England.) However, the past is the past.
It would certainly be important for the deal between the 2 operators to now be re-negotiated to accommodate the interests of MYT, which means in part their employees.
Members of Parliament around the UK are being pressed to review this employment situation in the light of this week's events, I understand. Quite right too. (It's not a European issue)
To balance things fairly, it should be recognized that MYT operate their a/c and crews in Canada every winter.
