in the old Soviet days, customer service hours aboard the entire railway were run based on Moscow time. This allowed for more convenient control by the central committee of the comrades at work in the field. If any question or problem arose on board the trains, the komissars in Moscow would be less likely to be disturbed when deciding what to do, or whom to liquidate.
This meant that the Trans-Siberian railway train served breakfast at 3 am, when running eastbound from Vladivostok.
Perhaps United's management is reverting to Soviet principles as they figure out how to run the world's largest airline?
