Well Rainboe I think cutting through the crap it boils down either to the fact it wasn't invented "here" or it hasn't got a Boeing sticker on it. If it did there would be exactly the opposite occurring where suddenly "new journey opportunities" would appear and airlines would be stupid not to buy it.
These claims are made fully in the knowledge that Boeing are trumpetting the -800 to challenge the A380.
It seems there is some sort of Boeing fan club that can't cope with not having the world's largest airliner anymore, much the same when there was no real challenge to Concorde and it was hounded out of the US.
Really not a very mature attitude and a strange one for a "spotters" forum where you'd think variety would be welcomed. Crackers. But disappointingly not unexpected.
