I am posting this here so that hopefully it won't start an A vs B like I know it would in the civil aviation forum.


Boeing says, "The Boeing 757-300 has the lowest seat mile operating cost of any single-aisle airplane on the market, and a lower cost per trip than any twin-aisle airplane."


Airbus says, "The A321 is the largest member of the A320 Family. It offers the best seat-mile costs of any single-aisle aircraft and is even on a par with widebody efficiency, bringing a new dimension to profitability."

Someone has to be wrong here. Which aircraft is the most efficient? B753 or A321?

Maybe they are the same?

From what I hear they base it on all sorts of variables so they are both right. For instance, they may be using different trip lengths to figure the costs. Airbus may figure it on a 1200 mile trip, while boeing might be figuring on a 2500 mile trip. Who knows? I'd love it to get an Airbus and Boeing engineer in here to hash it out. I'd be interesting to know.

My gut instinct tells me that it's the 753. Plus I think that the statement that Airbus made was before the 753 entered service.

I trust Boeing more than I do Airbus, but I do know the 757 can make routes like AZ to FL- I'm not sure the A320 can do that.

The A320/321 is very much able to operate transcon routes. Not very difficult to look up either.

Boeing says: blah blah blah

Airbus says: yadda yadda yadda

Basically, Boeing and Airbus can say whatever they want. You would have to not only factor in the plane, but such factors as routes, choice of engines, etc. On a sidenote, Boeing claims the 753 to be about ten cents cheaper per mile than the 752 albeit the larger engines.

Guys, they are talking seat mile costs.... you cram more seats into an aircraft and its seat mile costs go down. A very easy number to manipulate by any marketing/sales department. Both companies can be correct depending on the configuration. On the same aircraft a tour operator with single class meat wagon seating will have a lower seat mile cost than a full service airline with a multiple class configuration and increased leg room.

Sigh!  Insane

Aren´t there any accessible independent sources about comparative seat mile cost?

The A320/321 can certainly handle transcontinental flights. Look at what JetBlue is going to do with its new Long Beach hub.
