This kind of post is the perfect recipe for starting one of those wars!
The A32X is more fuel efficient, but maintainance and lease costs are much more expensive.
Comparative Fuel Burn in Litres/Hour (I got this from sources in an Indian carrier):
Code Fuel Consumption(l/h)
It could only be You! I see u are a kiddo, so i'll let this pass.
the figures can be crosschecked from the web-sites of Boeing and Airbus. Then there is another site which lists the detailed performance figures of all the aircraft. U could check out that site. Search for the topic "Fuel Burn rate" and u'll find it.
One piece of advice: dont get into these fierce arguments, unless you are sure about what u r saying. You may feel passionately about a particular aircraft, but that doesnt make it a better aircraft.
Airline economics are based on a number of factors, and for some airlines the A32X family makes better sense and for others the 737NG family makes more sense. United goes for A32X's and WN goes for 737's why? Both airlines are making money, so obviosuly both the planes concrened are doing their job.
This question was regarding fuel-burn, and i think i answered that question without any bias whatsoever. All BS is in your mind.
