“On-time” sounds simple. A car shows up when it’s supposed to, or it doesn’t.
But in event ground transportation, that idea causes more problems than it solves.
Events don’t move one person at a time. They move groups, schedules, and systems. When planners use the wrong definition of “on-time,” good programs look bad, stress increases, and costs rise without improving results.
Understanding what “on-time” really means is one of the most important steps toward running events smoothly at scale.

Why “On-Time” Gets Confusing at Events
In everyday travel, “on-time” means one thing:
Did the car arrive at the exact minute it was scheduled?
Events don’t work that way.
At events, many things happen at once:
- Dozens or hundreds of pickups
- Shared curb space
- Guests arriving in groups, not one by one
- Last-minute changes to flights, schedules, or venues
Because everything is connected, a small delay in one place can affect many others.
When people judge event transportation by exact timestamps, problems appear:
- Teams feel like they’re failing even when plans are working
- Escalations increase
- Stress rises for planners and operators
The issue isn’t performance.
The issue is the definition.
How “On-Time” Actually Works at Events
In event transportation, being on-time is measured using pickup windows, not exact minutes.
A pickup window is a short time range before and after a target pickup time. If the vehicle arrives within that range, the pickup is considered on-time.
These windows exist for a reason. They help the system stay stable when real life gets messy.
Different services use different windows:
- VIP and Executive Transportation: These pickups use tight windows. They also require more coordination and attention.
- Mixed Groups (VIPs, speakers, staff, guests): Windows are critical here. Without them, one late change can break the whole schedule.
- Shuttles and Shared Services: These use wider windows on purpose. The goal is to move many people smoothly, not perfectly.
What the Benchmarks Show
Most professionally managed event transportation programs aim for:
- 90–95% on-time performance
- Measured against pickup windows, not exact minutes
These targets are realistic. They reflect how complex systems behave in the real world.
Trying to hit 100% exact-time arrivals always backfires:
- Schedules become too tight
- Teams overreact to small changes
- One fix creates three new problems
Benchmarks exist to help systems work better, not to punish every delay.
Why On-Time Performance Breaks Down
When on-time performance drops, it’s usually not because of one mistake. It’s because several things happen together.
Common causes include:
- Passenger Readiness: A vehicle can arrive on time, but if the guest isn’t ready, the pickup still fails.
- Long Curb Dwell Time: When loading takes too long, curb space gets blocked. That delays everyone else.
- Last-Minute Changes: Every change forces schedules to shift. Too many changes overload the system.
- Late or Missing Information: Flight delays, location changes, or guest updates that arrive late make plans harder to execute.
These issues don’t show up as isolated errors. They stack up.
How These Problems Show Up in the Data
On-time performance usually fades slowly, not suddenly.
Warning signs include:
- Pickup windows getting tighter
- More overrides and manual fixes
- Delays clustering at certain times or locations
- Longer clearance times, even without traffic
These patterns matter. They show where the system is under pressure before things fully break.

The Tradeoffs Every Planner Faces
Defining “on-time” means choosing between tradeoffs.
- Precision vs Flexibility: Exact times feel precise. Windows are more forgiving and realistic.
- Tight Schedules vs Slack: Slack absorbs surprises. Removing it increases risk.
- One Guest vs the Whole System: Fixing one pickup can hurt many others. Events must be managed as systems, not single rides.
Good planners don’t ignore these tradeoffs, they plan around them.
What Planners Should Remember
A few lessons stand out:
- Exact timestamps don’t reflect how events really work
- Pickup windows explain reliability better than arrival minutes
- Realistic targets reduce stress, cost, and conflict
- “On-time” should match system behavior, not consumer habits
When planners redefine “on-time” correctly, they create calmer teams, better outcomes, and more predictable events.
The benchmarks and performance models behind this approach are detailed in Event Mobility Benchmarks in North America.
