Fleet Utilization

Sat Jan 24, 2004 7:48 pm

Gday

I just came across the fleet utilization data from the British Airways website and was wondering if these numbers are high or low.

Concorde (sadly no more): 1.6 hours/day on average per aircraft
747-400: 12.4
777-200A: 11.2
777-200IGW: 13.5
777-200ER: 12.2
767-300: longhaul 11.6 - shorthaul 6.6
757-200: 7.5
A320: 7.4
A319: 8.1
737-500: 8.0
737-400: 7.4
737-300: 8.0
ATR72: 7.5
RJ100: 6.7
Dash8: 8.0
ERJ145: 7.5

Does anyone have any information about other airlines? Which airline - apart from LCC's - would be better? To me it seems like the planes are on the ground for a very long time and I don't see why they couldn't be in the air a bit more??

Also what would an LCC's utilization be - I would expect quite a bit higher?

Thanks!

How exactly are these being differentiated.... GE90 versus Trent800?

I can't give you any concrete numbers, but for every hour an aircraft is in the air it requires "x" amount of hours for maintenance. Of course as the aircraft ages, it becomes more maintenance intensive. Also, technologically advanced aircraft spend more time on the ground at maintenance intervals because sometimes its harder to zero in on a problem because of systems intergration.

True, an aircraft is only making money in the air, and costing money on the ground. But, ground time, used correctly and efficiently should save you money.

777-200A are GE90-75B
777-200IGW are GE90-85B
777-200ER are Trent 895

I think the daily utilization rate for a 737, on average (for a LCC) is somewhere around 10-16 hours a day. Newer aircraft also have a tendancy to operate even longer, sometimes as high as 20 hours a day. BA's 8 hour daily utilization rate pales in comparison...

I don't know anything about the typical average of any of these planes, so I might be wrong, but don't these numbers, espcially the A320/319, 737's, and RJ's seem a little low?

...and the GE90-90Bs? Grouped in with the 85s?

easyjet of UK says it has a turnover rate of 20 mins on good days, and this is hampered by late passengers only! Hard to believe, but true. I think Southwest and Jetblue have one of the highest fleet utilization rates and prob. the highest turnover rates

I would say its up to the airline and schedule into how much they need their aircraft to fly.

I mean easyJet needs its aircraft in the sky to make their airline work, however airlines like Virgin Atlantic, BMi & British Airways its the schedule and on time 'ness' that’s the important thing.

I think to a degree most international large carriers will have a slightly lower utilization time then charter airlines or LCC's.

If you want to see high utilization times look at the British charter airlines during the summer months, such as MYT, BY & AMM.

Keep in mind, the larger the aircraft, the longer the turnaround time. Also, on longer flights, you are limited by the DEP/ARR times... you can't just turn the plane and come back immediately. A lot of time, then, is spent waiting for the oportune time to depart.

I'm not a pro within these terms, but what came to my mind:

- Only the aircraft costs themselves pay off the faster, the more hours the a/c is in the air (given some revenue on these flights). But fuel and crew costs, maintenance, landing fees are per-flight-values.

- Carriers which tend to keep their a/c for long time, may prefer to keep some life in them.

- The shorter the routes, the lower the utilization rate. But not all airlines are able to fly longer routes -- and I'll bet there are very lucrative short flights.

Regarding BA's commuter a/c, an utilization of 8 hours may not be THAT low, given that U.K. is not the size of the States...

Just my few cents... (too much work to be done here at home...  Laugh out loud )

The best way to sum it up is this:

A plane doesn't make money when it's sitting on the ground!

Well the above hours must also include the backup aircrafts, aircrafts for service etc.

In a fleet like BA's with over 300 aircrafts how many would be out of action at any time??? Is there a big difference between long and shorthaul aircraft?

Thanks!

I think their long-haul fleet has a pretty good "in air" time if around 11-12 hrs a day. Smaller jets have more rotations and more ground time due to that the turn around time on ground is much longer than long-haul planes.

I'm sure airlines using long-haul planes on short-haul flights (eg. Japan) have a more ground time and a lower air utilization time.

If I remember correctly Canada 3000 used to claim that they had the highest aircraft utilization rate of any airline in the world. A lot of good that did for them...  Smile/happy/getting dizzy The utilization on the A330-200s was around 16 hr/day.

I would have thought that the charter carriers would have the greatest utilisation as they have the same kind of short turnrounds as the LCCs plus they fly at all sorts of hours - Even the LCCs would have a job filling a 4am flight.

I've got the 1Q 2002 numbers sitting here on my desk. Per a/c type and per airline. I'm just not in the mood to type them all in.
