Why optimizing online check-in is one of the fastest ways to cut airline operating costs
:format(jpeg))
In short:
- Fuel volatility and route disruption are squeezing airline margins. Labor at the airport is the largest cost line operations can still control.
- Friction and errors in online check-in cascade into airport-side cost: more counter agents at peak, more exceptions at the gate, more complaints in the queue.
- ID Bolt shifts document capture upstream in days, not quarters, and is free to test in the browser right now.
In 2026 more than ever, airlines are operating in a margin environment they don't fully control. Jet fuel prices swing day to day. Airspace closures push routes longer. Last-minute cancellations and diversions ripple into knock-on delays. Passengers, meanwhile, are more price-sensitive than they have been in years.
The cost lever sitting in plain sight
Most of those forces sit outside the operations team's control. Labor at the airport is the largest controllable line item operations actually own.
Labor accounts for roughly 75% of airline non-fixed operating costs
Fuel may be bigger in absolute terms, but it sits outside operations' control. Labor doesn't.
Every passenger who arrives at the airport who hasn’t checked-in online, hasn’t completed check-in properly, or hasn’t got the correct verified travel documents becomes a workload event. Counter agents need to complete checks. Supervisors handle exceptions. Customer service teams field the complaints. Compliance teams absorb any API fines. Each one carries a labor cost.
Now flip it. Every passenger who completes check-in online before arrival, including accurate document capture and API, before they leave home is a workload event that didn't happen. And if there is an error or omission, there is still time to communicate it before it becomes a downstream issue.
It’s an underestimated opportunity that airlines can tackle in the short term to cut airport-side staffing pressure.
Why so many online check-ins still stall
The document step is frequently where it breaks and there are five common reasons:
Simple human error
Where document entry is manual, typos, mistakes, transposing numbers, and more are commonplace - especially when checking-in multiple people (i.e. a family holiday).
Capture UX is tricky, especially on a webcam
Even with ID scanning in apps or websites, slow or error-prone scanning means passengers abandon the process. Poor lighting, glare on a passport's bio page, a tilted angle, a low-end laptop camera when checking in via the website. When the scan fails or returns inaccurate data, passengers either give up and check in at the airport, or show up at the gate with a document the system didn't accept.
The passenger doesn't know what they need
International routes increasingly ask for more than a passport: visa stickers, eVisas, invitation letters, vaccination certificates. Requirements shift country to country and change without notice. If a passenger isn't sure what to provide, the path of least resistance is to defer the problem to the airport.

Discovery happens too late
Even motivated passengers often hit the document wall hours before departure, with no time to fix it. The problem lands in your terminal instead.
The cost lands on the operation: counter agents staffed for a peak that didn't need to be that high or a queue that didn’t need to be that long, supervisors handling exceptions, complaints stacking up in the queue or with customer service, and API fine exposure on the back end.
What changes when document checks happen before the airport
Scandit ID Bolt is built around a simple idea: make online check-in frictionless. Embed fast, accurate document capture at the points passengers already pass through, at booking and at online check-in, and most document issues get caught while there is still time to fix them.
Passengers using a laptop can even handover to their smartphone for a more intuitive UX i.e. a cleaner camera angle, without breaking the flow.
The completion numbers across our airline customers tell the story: 96% on mobile, 95.6% on web handover, versus 87.3% on webcam-only flows.
A few real-world effects:
- A large European airline doubled the share of passengers needing no additional document checks at the airport, from 30% to 60% after deployment.
- Where ID Bolt replaced a webcam-based capture, completion rose roughly 5x, and 95% of passengers who opened it completed the scan.
Each percentage point matters because each one compounds - and the downstream impact on operations is increasingly significant.
Smaller peak staffing windows

Reduced queues
When pre-airport check-in completion increases, peak-hour volume at the counter significantly decreases. This directly cuts the number of agents required to staff check-in, the supervisors needed to manage them, and the floor space they occupy.
Fewer gate exceptions
Higher capture accuracy means fewer passengers showing up with missing or invalid documents, and fewer manual checks at the gate as a result to streamline boarding and avoid departure delays.
Fewer complaints to resolve
A complaint that doesn't happen is a customer service interaction the airline doesn't have to staff, route, escalate, or compensate for.
Lower compliance exposure
Better data upstream lowers API fine risk and shrinks the compliance overhead at the back end.
Additionally by enabling customers to add scanned documents to their loyalty profiles, airlines can ensure accurate documentation can be re-used for future trips (within defined windows) and remove further friction and inaccuracy for repeat flyers.
ID Bolt: built to ship and impact in no time
The reason this transformation often stalls inside airlines isn't strategy. It is implementation. A multi-quarter integration with a dedicated engineering squad is not a project most operations or product teams can run alongside everything else.
ID Bolt is designed to remove that blocker:
- Pre-built and out-of-the-box, with integration measured in days not months.
- B2C-optimized web UX, built for first-time users on desktop, app, or anywhere in between.
- White-label theming, ID Bolt Studio, and an AI-powered configurator that auto-matches your site's colors, fonts, and style.
- 2,500+ supported documents, including passports, national IDs, drivers' licenses, and non-standardized travel documents.
- 9 preloaded languages plus custom text support, accessible by design.
- On-device processing, ISO 27001 certified, with no PII collected by Scandit.
The point isn't that ID Bolt is one more thing to buy. It is that ID Bolt is the fastest way to take the downstream operational costs out of check-in.
