What's the chances of us getting a weekly charter service to places like Las Vegas?
I'd say NIL & unnecessary! Many reasons :- Costs, & would involve a fuel stop, so why not simply fly United through EWR ?
As a holiday destination, would there be the demand for more or less full "Y"?, & again if there was, then presumably even more likely the operator could block book United...
Then one could simply book one of the currently available options from MAN access by road or rail.
