I am deciding to open a hub (4th one) in either Las vegas, Zurich, Washington, Copenhagen. Given that these cities do not have a high business rating and I'm in the year 1976, would it be worth relying only on tour ratings and will opening long haul routes (no stopovers) 10,000 km+ impact earning?
Would it be wiser to open a hub in cities such as Manchester, Liverpool or Luxembourg as they have medium business and tour ratings below 150 instead and what are the prospects of long haul routes (no stopovers) here?
Will any city improve their business or tour ratings beyond 200-250 in the coming years?
Should I wait for the economic crisis coming in 1978 to pass or open one shortly?
