Air freight is usually charged according to:
Chargeable weight, which is whichever is greater: the shipment’s actual weight or its volumetric (dimensional) weight. Volumetric weight takes the size of the shipment into account, so a large but lightweight consignment can cost more to transport than a smaller, heavier shipment. Understanding chargeable weight is essential when comparing air freight rates and calculating the true cost of shipping.

What Air freight rates actually means in 2026
For UK shippers, air freight rates is no longer a back-office function. It directly affects unit economics, conversion rate (through delivery promise) and working capital. The wrong setup quietly leaks 5–8% of margin every quarter; the right one compounds the other way.
Most of the confusion comes from terminology overlap. In WSUK's language, air freight rates means the operational service of storing, handling, and dispatching pallets or orders on behalf of a UK shipper. We focus on the commercial and operational mechanics that actually predict long-term fit. The job of this guide is to translate the jargon into commercial decisions you can act on this week.
If your annual volumes are growing, the cost of not getting this right scales linearly with you. That is why we wrote it as a framework, not a sales pitch. The closest companion piece is services, which covers the adjacent decision most teams face at the same time.
When air freight rates is the right call (and when it is not)
It is a fit when at least two of the following are true:
- Your monthly volume is consistent enough that a fixed contract beats spot pricing.
- You need national reach (or specifically the M1/M6 Golden Triangle) without owning the bricks.
- Service-level reliability is a sales argument for you, not just a back-office metric.
- Your in-house team would rather build product than run a forklift fleet.
Conversely, if you have unpredictable seasonal spikes and no base load, a contract is probably the wrong instrument — see sea freight for the alternative.
What "good" looks like operationally
A well-run setup ticks these boxes — and yours should too:
- OTIF above 98%. On-Time-In-Full is the single most predictive metric for customer churn in B2B.
- Inventory accuracy above 99.5%. Anything lower and your forecasts are lying to you.
- Damages under 0.3%. 1% sounds small until you price up a month of replacements and redeliveries.
- Same-day order cut-off no earlier than 4pm. Anything earlier is leaving conversion on the table.
- Sub-24h ePOD turnaround. If proof-of-delivery takes a week, you are funding your customers' working capital.
The full operational scorecard we use is in air freight.
Five mistakes UK shippers keep making
- Optimising for headline rate, not cost-to-serve. The cheapest pallet rate often comes with the most expensive accessorials.
- Signing without a peak-season SLA. Anyone can hit metrics in February.
- Skipping the site visit. Pictures lie. Pallets do not.
- Ignoring tech integration. Manual order files cost 8–12 picks a day in errors and rework.
- One supplier for everything. Dedicated couriers, networks and pallet storage are different products. They should usually be different contracts.
The fix for all five sits in our companion piece on air freight.
How to choose a partner without regret
Use a 5-step process and stop trying to compare apples and oranges:
- Brief. A one-page brief: volumes, peaks, SKUs, integrations, target service level. Anything more is noise at this stage.
- Shortlist by geography. 70% of your cost is driven by location. Filter to providers that genuinely operate in your delivery footprint.
- Site visit. Always. With your operations lead, not just procurement.
- Reference calls. Two minimum. Ask specifically about peak season and how a missed SLA was handled.
- Pilot. A 90-day pilot with clear exit clauses beats a 5-year contract every time.
A simple decision framework that beats spreadsheets
For the strategic call, use a 2×2:
- Volume predictable + high: dedicated contract logistics. See UK contract logistics.
- Volume predictable + low: shared-user 3PL with monthly minimums.
- Volume volatile + high: hybrid: contract base + overflow / spot. See overflow pallet storage.
- Volume volatile + low: pallet-network shipping with no storage commitment.
Most teams over-engineer this. The 2×2 is sufficient 80% of the time.
A realistic 60-day implementation timeline
| Week | Milestone | Who owns it |
|---|---|---|
| 1 | Discovery, volumes, peak profile | You + 3PL ops |
| 2 | Site visits, reference calls | You |
| 3–4 | Commercial proposal + SLA red-lining | Both |
| 5 | Integration spec (EDI / API / CSV) | Your tech + 3PL IT |
| 6 | Stock transfer plan, label re-work | 3PL ops |
| 7 | Parallel running, sandbox orders | Both |
| 8 | Go-live, daily standups for 2 weeks | Both |
Run it tighter than this and small problems compound fast. Run it slower and your incumbent learns you are leaving — never a good outcome.
Frequently asked questions
How quickly can WSUK onboard a new air freight rates account?
WSUK can assess and arrange an air freight shipment once the required shipment details are provided. The timescale depends on the origin, destination, cargo type, flight availability and customs requirements. For an accurate timescale, WSUK can confirm the available routing and service options when quoting.
What is the minimum commitment for air freight rates?
Air freight does not necessarily require a fixed storage-style contract or long-term commitment. Each shipment can be quoted according to its origin, destination, weight, dimensions, cargo requirements and delivery timescale. For regular shipments, WSUK can discuss an appropriate freight arrangement based on expected volumes and frequency.
How is air freight rates priced — per pallet, per pick or per order?
Air freight is generally priced according to chargeable weight, rather than a standard per-pallet or per-order storage rate. The chargeable weight is normally whichever is greater between the shipment's actual weight and its volumetric weight. The final quotation may also include applicable fuel, security, handling, customs and other freight charges.
Do you offer same-day couriers alongside scheduled distribution?
Urgent and time-critical transport can be arranged alongside scheduled distribution, subject to availability and the specific requirements of the shipment. For particularly urgent consignments, air freight or dedicated courier services may be considered depending on the origin, destination and required delivery time.
Where are WSUK's facilities located?
WSUK's primary footprint is the UK Golden Triangle — Northampton, Daventry, Crick, Coventry, Rugby — with national delivery via a tiered pallet network. That puts ~85% of the UK population inside a single overnight delivery promise.
