No no no
The Heathrow used to be done 5 times a day and was fairly full every time. A320s are sometimes used on the Heathrow at the moment and even the odd A321. Previous aircraft have been 737s and DC9s so there is definetly enough people out there to fill an A320 3 times a day. On top of that remember Newcastle have alot more flights into Heathrow as well as having flights to Gatwick and Stansted so there are plenty of passengers out there wanting to fly to London.
Oh by the way BombadierCR7 baby flights doing just fine mate. 10% of all seats for the summer sold in the first weekend, seems they got it right. So if you actually knew what you where on about you would keep quiet or comment on things that happen in Berlin not something that goes on at Teesside!!!
