The Receipts #2: What Airline Checklists Teach Your Business
_By Ruth Maclang | The Receipts Series_
Most businesses run entirely on someone’s memory.
And then that person gets sick. Takes a vacation. Has a bad week. Everything collapses.
I learned about checklists the hard way. Philippine Airlines, then Oman Air. Both times, same training.
At 35,000 feet with 300 people on board, you don’t freestyle the safety check.
You follow the checklist.
Every. Single. Time.
Why checklists matter at altitude
When I started at Philippine Airlines, I was excited to impress. I wanted to do things perfectly, to show I cared about the job.
My trainer was a 15-year veteran. Smart. Efficient. She looked at me and said: “Forget perfect. Follow the process.”
We had paper checklists for everything. Pre-flight. In-flight service. Emergency procedures. Turbulence protocols. Crew rest rules.
The checklist didn’t care if you were having a great day or a terrible one. Didn’t matter if you were tired or sharp.
The checklist was the standard. That’s what got executed every single flight.
I asked my trainer once: “Don’t you get bored doing this the exact same way?”
She said: “The boring is the point. If I get creative with a safety procedure, people die. The checklist isn’t there to make the job interesting. It’s there because the stakes are too high to leave to memory.”
The stakes in your business
Here’s what I realized later: your business has stakes too.
Different kind. Not life and death. But real stakes.
Your revenue. Your reputation. Your customer’s trust. Your team’s paycheck.
When the founder is the only person who knows how to fulfill a client deliverable, you have a single point of failure.
When the process for onboarding customers exists only in your head, you can’t take a week off without anxiety.
When the system for managing finances or client communication or product quality is “call me, I’ll explain it,” you’re not running a business. You’re running a bottleneck.
What a proper checklist looks like
At Oman Air, the systems were tighter. Everything had documentation.
Not just “do the service.” But: open cabinet A, count the items, verify the manifest, load in this order, present to customer in this sequence, document the stock level.
Steps. Order. Accountability. Record.
If something went wrong, you could trace it. You could see where the breakdown happened. You could fix the system instead of just fixing the person.
I watched someone cover a shift they’d never done before. She had the checklist. She executed flawlessly. Because the process was the safety net, not her experience.
That’s what separates a founder who can take a vacation from a founder who’s glued to their desk.
The founder who has a checklist can leave. The checklist runs it.
The three things you need
If most of your business runs on your memory, you need to fix this. Fast.
Not because it’s a nice-to-have. Because every day you don’t, you’re building a house that only you can live in.
Here’s the minimum:
1. Document the process
Write down how it actually works. Not how it should work. How it works right now, in reality. Step by step.
When a client comes in, what happens first? Then what? Then what? Get it on paper.
2. Write the checklist
Break it into repeatable steps. Checklist, not memoir. “Call the client” vs. “have a great conversation about their needs.”
Specific enough that someone else could follow it. Boring enough that there’s no interpretation needed.
3. Follow it every time
The system only works if you use it. Every time. Not “most of the time” or “unless I’m busy.”
The value isn’t in having a checklist. It’s in the discipline to follow the one you have.
What happens when you don’t
I’ve watched this play out dozens of times with founders.
The business runs on the founder’s memory for years. Works fine because the founder is there, thinking about it, always showing up.
Then the founder needs help. Hires someone. Spends three weeks explaining what they do, but the new person is never quite as good because the process was never really in their head.
Or the founder gets burned out. Checks out. The business stalls because nobody knows what’s supposed to happen.
Or the founder tries to scale. Wants to move faster. But they can’t because they’re still the bottleneck. They’re too busy remembering what comes next.
A checklist fixes this.
The lesson
You don’t need to be a genius to run a world-class operation.
You need a checklist.
Systems created by people who’ve done the work, documented for people who haven’t done it yet, followed every single time regardless of how you feel that day.
The checklist is what makes 35,000 feet safe. Not the brilliance of the flight attendants.
The checklist is what makes your business scalable. Not your hustle.
FAQ
Q: Doesn’t a checklist make things boring?
A: The boring is the point. When you remove chaos and guesswork, boring becomes reliability. Boring is where consistency lives.
Q: What if my process changes all the time?
A: Then document what’s changing and why. Update the checklist. The system evolves, but you’re still following a process. You’re not starting from scratch each time.
Q: How do I know what to put on the checklist?
A: Watch yourself do the work. Every step. Every decision. Every output. That’s your checklist. Strip out the personality, keep the process.
Q: What if my business is too complex for a checklist?
A: Your business isn’t too complex. You just haven’t broken it down far enough. Complex things are made of simple steps chained together. Document the steps.
