To use it you have to have a ticket valid on the Underground because you
have to go through an Underground gateline and the route is much slower
and
more convoluted than the above ground way. The weather would have to be
really atrocious for it to be a sensible route when starting at ground
level.

If you have a ticketvalid for a through journey that involves changing from
Kings Cross or St Pancras to Kings Cross Thameslink, you almost certainly
have a ticket with LUL validity. Are there any tickets which will work the
gates at KXTL but not at KX (LUL)?
