On-time performance still is the number one operational performance indicator for airlines.

It is published regularly, analyzed to the very detail — and more and more frequently it is shown in real-time to relevant stakeholders.

An increasing number of airlines do have some kind of dashboard — especially in their operations or network control center — where the OTP is displayed in real-time.

Nonetheless, what I observe is that most often the OTP is presented as one bold number only.

Acutally, this isn’t wrong but I’m strongly convinced that there’s so much more you can do with the OTP. And with so much more you can do, I’m also convinced that there’s much more benefit to all stakeholders in it.

So instead of showing one bold number, here are 4 strategies to make more out of your OTP:

Use dimensions

A global OTP is important, but in day-to-day operations and for a perfect situational awareness, very often it is necessary to apply dimensions to the OTP.

Think about showing your OTP for your different sub fleets — how is your Boeing fleet performing in relation to your Airbus fleet. Or even more specific compare your 747 to your A380.

Same applies to your airports. How does your OTP look like on your most important hubs or outstations?

Third idea is to cluster the OTP according to different traffic regions. Are your flights to Asia performing better than your flight to North America?

I guess you can see, there are lot of possibilities in applying dimensions to one global KPI like the OTP.

Use hit lists

Based on the above idea with dimensions you can take this even one step further and provide hit lists.

What are your TOP 5 airports when it comes to on-time performance?

Or move away from airports and take complete flight/routes into consideration. Which routes are performing best in terms of OTP?

And of course, this also works again for other dimensions like sub fleets or aircraft.

Reverse OTP

A simple trick to really focus on an important aspect: Instead of showing the on-time performance, show the percentage of unpunctual flights.

This, especially, works very well for thresholds which are very important to comply with.

For example, many of our clients have a close eye on 180-minute punctuality.

And instead of showing the percentage of flights which are below 180 (this would normally be around 99%), they show the opposite: The percentage of flights with a delay >180.

Since everybody knows that this KPI has to be 0%, already a value of for example 1.5% or 2.1% looks very dangerous.

Enrich your on-time performance KPI

I’ve already wrote a whole article about enriching KPIs in general. This, of course, applies to OTP to.

Think about adding target values, an average or historical data in order to provide context to your users.
