Md-80 Operating Costs Compared To A320

Wed Feb 02, 2005 12:20 pm

Hey,

Is the Md-80 series a costly aircraft to maintain and operate? Does it burn alot of fuel? How does it compare to a 737 NG or A320 family aircraft?

Regards,

I'll say cheaper to use 1999-built MD-83 on ORD-SFO route than 1990-built A320. I hope I am correct.

September11: not necessarily correct from a powerplant standpoint. Even the new MD80 series use JT8 series engines, all of which are medium bypass with a ratio of 2:1 (1:1 in 727). Lower bypass ratios are less efficient at subsonic cruise speeds. The A320 series utilize high bypass turbofans (4:1 bypass ratio or higher) and are much more efficient.

There are other factors of course, just my 2 cents though.

I believe MD83 is equipped with the upgraded JT8 which is lighter and more fuel effecient.

How ever i am very interested in getting some numbers on this comparrison.

PIA747: Don't get your point, why would airlines like Austrian, old-Swissair, Alitalia,... and others replace their MD80's with A320 family or 73G's if they were not more efficient and cheaper to operate in the longer term, add to their efficiency the noise level of the MD80's, some airports charge their fees taking into consideration the noise category, you cannot operate MD80's from several airports during the night curfew that is imposed, in certain cases you can take-off but you have to pay extra noise fees.

The JT8D-200 series found on all MD-80s is a relatively low bypass turbofan. The A320's engines, and the 737NGs, are significantly more efficient.

The MD-80 has a narrower cross section which could make it more efficient than the A320.

While the MD-80's are lower bypass, they are also lower powered and lighter. Also, the MD-80's frame is lighter. There really is no comparison on range and cargo carriage, where the 737/A320 win hands down.

I found here: http://www.icao.int/icao/en/ro/allpirg/allpirg4/wp28app.pdf that the MD-80 and A320 have roughly the same direct operating cost per hour (as of summer 2000), while the 737G has a little lower, and the 738 even lower DOC/hr.

MD-80: $2,285
MD-87: $1,827
A320: $2,273
A319: $2,156
737G: $1,993
738: $1,583

Fuel consumption seemed to be the main factor in determining the differences between DOC/hr.

MD-80: 799 gal
MD-87: 741 gal
A320: 886 gal
A319: 821 gal
73G: 690 gal
738: 564 gal

As that list was done in 2000 before fuel shot up, jetfuel prices were pegged at $.70, so while the operating cost order remains the same, double the fuel costs listed on the website to find a more accurate DOC.

If those figures were true, no airline would ever buy the 73G

Well they're from the ICAO, and the 73G is still cheaper to operate than its direct competitor, the A319...

The 73G is a little misleading as it is lumped together with the 733 for whatever reason (none of the other planes are joined like that).

Actually, the MD-80 has a slightly higher cost per hour according to the above figures, compared to the A320, but the A320 carries a few more passengers, and substantially more cargo. Therefore, the revenue potential for the A320 is greater than with the MD-80.

The fuel efficiency of the 73G is quite impressive, and I'm wondering if that's mainly a factor of its higher cruise altitude thanks to its larger wing?

Considering the low lease rates of MD80, particularly the MD83 make it an attractive choice for start up low cost operation. This can be seen in airlines such as jetsgo, Kalula, Lion air and several more in Indonesia.

End of 2003, MD82s would be about 1600USD/H ACMI based on 250hrs per month...

Anyways, Lion seems to be the only one in Indonesia that is going big with the MDs... Bouraq gave up their MDs, Star seems to be the only other one here... Airfast also recently began using MD80s, but mainly for charters/732 supplement...

For 12 months ending Mar 2004 for US based reporting airlines....from Eclat

Average Block Hour costs (ave seats):

MD80 - $2,725 (134)
A320 - $2,387 (147)
737-800/900 - $2,498 (153)

Each of these had at least 5 airlines reporting. Keep in mind that stage length differed, so it still isn't a 100% accurate comparision.
