Please this is becoming embarrassing!!
When Airtours moved lock stock and barrel to Teesside long haul inc, travel agents were offered double commission to book from Teesside and still couldn't turn people away from NCL!! I remember the posters all over Sunderland telling me Teesside was my local airport!! Then the horror stories of friends being duped to fly from MME as no other flights existed from NCL!! Never mind the people who got lost trying to get there!!
Travel agents are probably used to the much larger amount of holidays available from NCL and so go there first??
Plus how many people use travel agents these days?? Does NCL make people not press the Teesside button??
