love a good Luddite response
That's a little unfair.
It's a risk game- invest in proven technology and risk missing out on the advantages of the new,
Or invest in emerging technology and risk it not meeting it's promise.
Emirates has hedged it's bets and done well.
QANTAS, as an exapmle, didn't want the "Old technology" 777 and so hitched it's wagon for a (badly needed) fleet renewal on the A380 and the 787.
..and see how THAT turned out!!
