The Space Between

When it comes to traveling, there’s almost nothing worse than getting to the airport and discovering your flight is delayed. When you fly as much as I do, every minute counts. That’s why the very latest reliability stats on the Next-Generation 737 translate into good news for all of us.

The new numbers show that 99.67 percent of all Next-Generation 737 flights are ready to depart within 15 minutes of their scheduled time. Compare that to the A320 at 99.35 percent. While the gap may not look that big, it means a world of difference for you and for our airline customers.

Here’s another way to look at it. For a fleet of 100 Next-Generation 737 airplanes flying five flights a day, the 737s will have 590 fewer delays and avoid disrupting 66,600 fewer passengers each year when compared to a fleet of 100 A320s.

I recently showed this example during a series of presentations in Seoul and Taipei. People were genuinely surprised to see what a significant reliability advantage we have over the competition right now—and will continue to have in the future. The space between us is very telling.

Speaking with media about the MAX during stops in Taipei and Seoul.

While it saves you time, it saves the airlines money when it comes to maintenance, flight and crew costs. It’s a great story with many more chapters to come as the 737 MAX enters the scene.

For those of us who fly, reliability is everything. Which is why when given the choice, I will book newer 737's and 777 ahead of anything else out there, except the Dreamliner of coarse.

Thanks again Randy for keeping us aviation fans and flyers updated on the latest and greatest from Boeing. Please keep it up.

Evan (St Louis):

Was there ever any doubt? Wonderful news and incredibly promising for the Max.

Andrew Boydston (Boise, ID (USA)):

Reliability has an exponential affect on the operator's bottom line. As you stated well in your journal. Just one half hour delay sends sock waves through an operations resources needed to deal with the problem. An "over-nighter" means putting up people into lodging, inconveniencing ticket holders, or losing their business, which spirals cost of lost revenue and increases expenses.

Expediting the repair has a premium to pay. A slight schedule delay or an over-night delay is a financial nightmare. It spells doom to the bottom line, reputation and business health.

Scheduled Maintenance is a requirement and number of maintenance cycles needed is a key. If you can monitor the aircraft from internal data and plan the next maintenance call you do not interrupt the mission. Turn around is faster where resources are planned, time slotted and work is efficient. That's competing with your best pit crew, instead of pushing into the shop and ordering parts.

Thank you Randy for your timely Journal. It makes me think about aviation in an efficient and effective manner.

Norman (Long Beach, CA):

On the news from Bloomberg that United Airlines is looking as a massive order of 737NGs and 737MAX I cannot imagine a better time to show the statistics of the 737 over the A320 family. I think United is due for a large order to replace it's aging fleet of 737 classics, 757s and A320s and so is Delta.

Jimbo (London):

Randy,

You have to compare Apples with Apples.

The A320 fleet has been produced since the mid 80's, much like the 737 Classics, so a fair comparison would be the combined reliability of the 737 classics AND the 737 NG against the A320 fleet. Much smaller gap....the graph I'd like to see is the Schedule reliability of the last 1000 737NG vs the last 1000 A320. I think you'd see a different story.

It's all about how you twist the numbers! NEO vs MAX is going to be interesting...

Frank McAvennie (London):

Randy, I'm a little confused with your dispatch figures compared to those of the A320. According to Airbus, their dispatch reliability is currently 99.7% on the model, not the 99.35% you quote here. Perhaps you could clarify this particular point. Either way, I am sure both the MAX and NEO will be assets to the airlines operating and manufacturers building them. Best wishes
