Linehaul is the long-distance leg of a shipment’s journey between two fixed hubs or terminals, the middle segment that connects first-mile pickup to last-mile delivery. On the ground, linehaul is shaped less by raw distance than by federal hours-of-service rules: a truck driver is legally limited to 11 hours of driving within a 14-hour on-duty window, and running out of legal hours mid-route means a mandatory rest stop or a driver swap, not a faster way through.
What linehaul actually covers
Linehaul sits between the two legs most shippers think about first.
- First-mile pickup, collecting the shipment from the origin and bringing it to a hub or terminal.
- Linehaul, the scheduled long-distance segment connecting that origin hub to a destination hub, often full truckload trucking on a fixed dispatch schedule.
- Last-mile delivery, moving the shipment from the destination hub to its final recipient.
Why the driver’s clock limits the route more than the map does
Federal hours-of-service rules set firm limits on how long a single driver can legally keep a linehaul truck moving.
- An 11-hour driving limit within a 14-hour on-duty window, which starts counting the moment a driver comes on duty and cannot be paused.
- A mandatory 30-minute break required after 8 cumulative hours of driving.
- A 60 or 70-hour weekly limit, which requires a 34-hour reset once reached, regardless of how urgent the freight waiting behind it might be.
Time spent waiting to be dispatched, loading, or held up in detention at a dock all counts against that 14-hour window before the truck even starts moving, which is why a delayed pickup can quietly cost far more driving time than it first appears to.
What happens when a linehaul run runs out of legal hours
A driver who reaches the legal limit mid-route cannot simply push through to save time. The options from there are limited and each one adds delay.
- A mandatory rest period, holding the shipment in place until the required off-duty hours have passed.
- A driver swap, which requires a second driver to be available at the right location, something not every linehaul network can arrange on short notice.
- Missing the scheduled onward connection, since linehaul runs typically operate on a fixed dispatch schedule, not a continuous departure cycle, so a missed run often means waiting for the next scheduled one rather than the next available slot.
Where a scheduled flight avoids this constraint entirely
An onboard courier moving the long-distance segment by scheduled commercial flight is not subject to the same incremental driving-hour depletion a ground linehaul route accumulates. The flight itself is a fixed-duration segment, already scheduled and crewed by the airline, rather than a route whose duration depends on how much of a single driver’s legal clock is left when the truck departs.
Linehaul vs. onboard courier for the long-distance segment
| Criteria | Ground linehaul | Onboard courier |
|---|---|---|
| Governing constraint | Federal hours-of-service limits on the driver | Scheduled flight duration, already fixed |
| If time runs out mid-route | Mandatory rest or a driver swap | Not applicable, the segment is a fixed flight |
| Best for | Routine freight with normal flexibility | Deadlines that cannot absorb a driver’s mandatory rest |
| Typical cost | Lower, standard linehaul pricing | Higher, priced per mission |
How OBC ONE handles the long-distance segment of a mission
A typical mission runs through six steps with OBC ONE, most of which overlap to save time.
- Brief and quote. You share the shipment, origin, destination, and the deadline. OBC ONE returns an all-in quote in under 15 minutes.
- Routing check. We confirm the actual scheduled flights available, rather than relying on a ground linehaul schedule that depends on a driver’s remaining legal hours.
- Courier assignment. A vetted courier near the origin is dispatched immediately.
- Personal custody in transit. The courier carries the shipment in the cabin, staying with it through every connection.
- Direct delivery. Handover happens with the named recipient, not a generic terminal.
- Proof of delivery. Timestamped confirmation for your records.
Why freight forwarders route these missions through OBC ONE
Choosing the right partner for a deadline that cannot absorb a driver’s mandatory rest starts with the business model. Many specialty couriers sell directly to shippers, which puts them in competition with the forwarders who might otherwise use them. OBC ONE is built the opposite way: we work exclusively for and with freight forwarders and time-critical desks. We never approach your clients directly and never compete with you.
That partner model is backed by real operator experience. OBC ONE was founded by an onboard courier who personally flew roughly three million kilometers over six years, so the network understands exactly where a ground linehaul schedule quietly runs out of margin. Forwarders use us because we deliver:
- An all-in quote in under 15 minutes, 24/7/365.
- 1,500+ vetted couriers positioned around major hubs worldwide.
- True door to door coverage, with import and export customs clearance and Importer of Record service in most markets.
- IATA certified dangerous goods capability for shipments that require it.
- One specialty, onboard courier and hand carry for time-critical missions, done at the highest standard.
How to choose a partner when a linehaul delay is not an option
- Real awareness of hours-of-service constraints, not just a headline transit time.
- Routing planned per mission, rather than defaulting to whichever ground schedule a generic network happens to run that day.
- Fast, transparent quoting, ideally with a named dispatcher accountable for the mission.
- Real network density near major hubs, so the courier itself is not delayed by being flown in first.
- A forwarder-only model, if you are a forwarder, so your partner never becomes a competitor for your clients.
Frequently asked questions
What is linehaul?
Linehaul is the long-distance leg of a shipment’s journey between two fixed hubs or terminals, connecting first-mile pickup to last-mile delivery, often operated as scheduled full truckload trucking.
Why do federal hours-of-service rules matter for linehaul?
A truck driver is legally limited to 11 hours of driving within a 14-hour on-duty window, with a mandatory 30-minute break after 8 hours and a 34-hour reset required once weekly limits are reached, all of which shape how far a single driver can legally take a linehaul run.
What happens if a driver runs out of legal hours mid-route?
The shipment either waits for a mandatory rest period to pass or requires a driver swap at the right location, and may miss its scheduled onward connection entirely, since most linehaul networks run on a fixed dispatch schedule rather than continuous departures.
Does time spent waiting at a dock count against a driver’s legal hours?
Yes. Time spent waiting to be dispatched or held in detention at a pickup or delivery point counts against the 14-hour on-duty window, even before the truck starts moving.
How does an onboard courier avoid the hours-of-service constraint?
The long-distance segment moves by scheduled commercial flight, a fixed-duration segment already crewed by the airline, rather than a route whose duration depends on how much of a single driver’s legal clock remains.
Do you sell directly to shippers or buyers?
No. OBC ONE works exclusively with and for freight forwarders and time-critical desks. We act as a white label partner and never approach our clients’ customers directly.
