Jetblue's Cost Structure - Good Article

[OakRBust]

I have been thinking alot about the 199 seat 75's. We are racing to turn a 137 seater in 25 minutes. I would be really surprised to see Song turn a 199 seater in much less than 45 minutes or so. Anybody know what the planned turn times are going to be?


A 20 minute difference in turn times for lets say a scheduled 8 flight day would be a whopping 2:40 minutes lost in available flight time per jet. That might make the extra seats a disadvantage.



Just a thought

I just finished a study on exactly this topic. From memory, I believe the Song leadership was quoted saying they were "going to try for a 50 minute turn". I do not know what they are currently doing in actual operation, but it would be easy to go to Song's website to see.

Yes, there is a huge hit in lost productivity from long turn times, until you operate all nighters to make up for it.

Comparing notes with a Southwest crew and a United crew, both flying up and down the west coast. Where we fly 5 legs, they fly can fly 6. Our duty day is 2 hours longer, for 1 hour less pay (after figuring the trip-hour conversion for SWA pay). The reason SWA is more "productive" than us (UAL) is the average 55 minute turn times. This was an easy apples to apples comparison, because we both fly 737's. The only extenuating circumstance is that they fly through OAK and we fly through SFO, which often has delays and needs "pad" built into the turn times to keep on schedule.

I read that Song was considering the all night trans cons, similar to B6's. This would allow them to increase the utilization.

The other thing that a DAL buddy of mine was telling me was that mgt was looking into the Jet Bridges with the aft exits. This would allow them to turn the aircraft much quicker.

One more thing to consider is that B6 is not all that concerns Song, they have Airtran in ATL to deal with. Airtran is not going to get a 717 out of LGA to ATL any faster then Song is going to move a 757 out of JFK. Samething with ATL, by the time Airtran turns a 717 in ATL, Song could be moving a 757. Especially if they have dedicated Song 757 double jet bridge exits.
Maintianing market share in ATL is probably a greater concern then JFK for DAL mgt.

G4G5,

We know that Airtran is becoming more of a threat in ATL, but until they build the new terminal on the Southside of the airport, Airtran will have a hard time growing or adding capacity due to the lack of extra gates. We know that they will expand more when they get that terminal, and hopefully by then (3 years atleast---they haven't built the extra runway either) we will be leaner to compete with them. They added Ryan A320's to LAX and LAS, and we have also increased our service to the LA Basin to 22 daily flights.


OAKRBUST,

Well, I have heard and seen what they are doing for the quicker turn times, and it mainly involves deplaning the people out of the L2 or Left 2 door with the front of the plane exiting first, and as they leave we have cleaners come in the front right service door and start to clean immediately. Then cleaners also invade the back of the 757 as those people move forward, and the cleaners try to meet in the middle. The passengers are also boarded a little different to expedite the process. Yes, there have been some kinks, but they are learning how to get it done.

Bye Bye--General Lee

Here is something to ponder...

We have about 2700 flights per day. Our typical turn time is 25 minutes. Each 5 minute increase in turn time costs us 13,500 minutes in the daily schedule (2700 daily flights * 5 minutes = 13500 minutes). That equates to 225 hours that the planes aren't flying.

We currently have 379 planes. Lets say that each of our flight segments averages 1.5 hours. 2700*1.5 = 4050 flight hours per day. 4050/379 = 10.68 hours / plane/ day

To cover the same schedule with a 5 minute longer turn time...

We would still need to cover 4050 flight hours. We lose 225 flight hours for every 5 minute increase in turn time. 4050-225 = 3825
3825 /379 = a new a/c utilization of 10.09 hrs/plane/day.
If we take the lost 225 hours and divide it by the new utilization rate of 10.09.... 225/10.09 = 22.29 additional planes required to complete the same flight schedule. (WOW)

Five minutes seems like mothing but all I can say is WOWOWOW. Every minute really does count.

NOTE TO EVERYBODY!!!! I am not a math major so there could be a few flaws in my calculations. I also am not saying that our average flight is 1.5 hours as I am sure that it is quite a bit higher. 1.5 just made the math easy.

OakRBust,

Actually, your average stage length is 723 miles. Looking for a good comparision for that, I chose MCO to HOU which is 740 miles. According to your schedule, that takes 2:25 block to block. Turn times are especially important at SWA, but are important everywhere. Only three ways to increase aircraft utilization:

1. Lengthen stage length
2. Decrease turn time
3. Fly as much around the clock as possible (all nighters)

JetBlue's average stage length is 1169. United's domestic stage length is about 1010 (numbers fluctuating daily). USAir is around 650. I'll let someone else crunch the impact on these airlines for their turn times.

End product is that JetBlue has the highest utilization (see three reasons above) at 13.1, SWA is next with 11.5, and United is below 8. Simple, keep the airplanes flying and they make money.

Jetblue internet

Jetblue is now testing wireless internet on one plane. With maybe a fall announcement of fleetwide capability.
