Don't think a 777 from SOU to NYC has ever been suggested, but depending on the nature of the recovery, I think the example of Southend is a good one - can't say I'm an expert on the repective areas but the impression I get is that the catchement area of SOU is a wealthier one?
If we keep the discussion sensible and restrict it to narrow body operations around Europe, who are you excluding from operating from SOU?
