You will find the only Newcastle tech stops were for My Travel (nee Airtours) who had a strange ops manual with regard long distance departures off runway 25 with the A320. Other operators with same type/engine and same destinations having no problems!
As for other long distance routes well Newcastle has had no problem with direct Orlando with the A330 –200 OR 300 series. Even the 767’s make it mostly direct 90% of the time.
At least Newcastle can fill 2 or 3 Orlando’s a week, Teesside if I remember, when you had Orlando’s, always routed via another destination to pick up more pax’s!
