The Airbus A380 is an impressive plane, huge and luxurious, and rumor has it that the next step, A390 will have 10 decks and features that would make you believe it was Titanic flying in the air. To that Boeing's offering is much smaller in size, but said to be more efficient....consuming 20% less fuel than similar sized aircrafts. Given the delicate balance our environment hangs in.... do we really need these huge things to help tip the balance the wrong way???? what say U???

I won't mind traveling in Titanic anytime. As far as the "CO2" problem is concerned.....if I don't sit in it, its unlikely that it won't fly...better make use of all the seats available and help make it more efficient
