Well... there's an abundance of them then. I haven't heard of any airline that wanted to operate to JFK but couldn't because of slots.
That's not true. jetBlue was only able to begin services due to a slot exemption policy facilitated by the Senators from New York.
How can that be? Virgins VS045 leaves LHR at 08:25 while Concorde left at 18:30. I know Concorde is fast, but not that fast!
I think he might be referring to AF
's Concorde, which did arrive in time to get you to Manhattan by 9:30.
