Air Freight: Why Timing Matters as Peak Season Approaches
For businesses moving international cargo, September is the point in the calendar when delivery dates start to become much more important.
The final quarter brings higher retail demand, product launches, seasonal stock movements and year-end production requirements. Add China’s Golden Week in early October, changing airline capacity and the usual increase in time-critical shipments, and there is less room for freight plans to go wrong.
That doesn’t mean air freight capacity is suddenly unavailable. It means shippers need to be more deliberate about when and how they move cargo.
For some shipments, ocean freight remains the right choice. For others, waiting several weeks for a vessel simply isn’t practical. This is where air freight becomes a useful part of the wider supply chain.
What is air freight and when should you use it?
Air freight is the transportation of commercial goods by aircraft, usually used when speed, reliability or the value of the cargo makes faster transport worthwhile.
It is generally more expensive than ocean freight, so it isn’t automatically the best option. The decision comes down to the cost of time as much as the cost of transport.
A delayed component could hold up a production line. A missed retail launch could leave stock sitting in the wrong country. A spare part may be inexpensive compared with the cost of machinery standing idle.
In these situations, the question isn’t simply, “How much does air freight cost?”
It is, “What does it cost us if this shipment arrives late?”
That distinction matters.
Why air freight is particularly relevant right now
The global air cargo market has continued to grow through 2026.
According to the International Air Transport Association, global air cargo demand increased by 3.9% year-on-year in July 2026, while available cargo capacity increased by 1.7%. European carriers recorded 4.4% growth in demand, while Asia-Pacific demand increased by 4.1%.
However, the market isn’t moving in one uniform direction.
Demand and capacity vary considerably between routes. IATA reported particularly strong growth on the Asia-North America trade lane, while Europe-Asia continued to grow. At the same time, some routes connected to the Middle East remained disrupted.
For importers and exporters, this matters because an air freight market can look perfectly healthy globally while a particular origin, destination or departure date becomes much harder to secure.
That’s why experienced freight forwarders look at the individual shipment rather than relying on a single global market headline.
Peak season air freight: why September is the time to plan
The traditional autumn peak doesn’t arrive overnight.
Demand builds as businesses prepare for the final quarter, and October brings China’s Golden Week, when factories and businesses close or operate with reduced staffing across the national holiday period.
For companies importing from Asia, this can affect production schedules, cargo availability and departure planning. Maersk’s September market update specifically recommends reviewing shipment schedules and space requirements ahead of Golden Week and Q4 requirements.
Air freight can become particularly important when a shipment needs to move before or after a factory closure, or when goods that were originally planned for ocean freight suddenly need to arrive sooner.
There is another consideration.
Current market commentary suggests that late-September air freight conditions are becoming more dependent on individual trade lanes.
In other words, leaving a time-critical booking until the last possible moment can reduce your options.
How long does air freight take?
Transit time depends on the origin, destination, airline, service level, routing, customs requirements and final delivery location.
An airport-to-airport flight may be relatively quick, but that isn’t the same as door-to-door transit time.
A shipment still needs to be collected from the supplier, prepared for export, documented, security screened, delivered to the airport, loaded, flown, cleared through customs and transported to the final destination.
For that reason, businesses should avoid planning around the flight time alone.
If your customer needs stock delivered by Friday, for example, the useful question isn’t how long the aircraft spends in the air. The useful question is whether the complete shipment can realistically move from supplier to final delivery address within the required window.
That’s where freight forwarding experience becomes important.
What does door-to-door air freight include?
Door-to-door air freight covers the complete movement rather than simply arranging space on an aircraft.
Depending on the shipment, this can include:
- Collection from the supplier
- Export documentation
- Airline booking
- Airport handling
- Cargo security requirements
- Customs clearance
- Import documentation
- Final-mile transport
- Delivery to the consignee
- Shipment tracking and updates
Future Forwarding provides air freight support from booking through customs clearance and final delivery, giving businesses a single point of coordination across the shipment.
This is particularly useful for urgent shipments because airport-to-airport transport is only one part of the logistics process.
A flight arriving on schedule doesn’t help much if customs documentation isn’t ready or there is no vehicle arranged for the final delivery.
Can air freight help when ocean freight is delayed?
Yes, and this is one of the most practical uses of air freight.
Businesses don’t always need to move an entire shipment by air.
Suppose a container contains 500 units, but 50 are urgently needed to keep production running. Rather than replacing the entire ocean shipment with air freight, the urgent quantity could potentially be moved by air while the remaining cargo continues by sea.
This is sometimes referred to as a split shipment or air-sea strategy.
It allows the business to protect the most time-sensitive part of the order without automatically paying air freight costs on everything.
The right approach depends on the cargo, route, dimensions, value, delivery deadline and available services, but it is an option worth discussing when supply chain delays start creating operational problems.
What should businesses consider before booking air freight?
The most important information is usually the delivery deadline.
Start with the required arrival date and work backwards.
Consider:
- When will the goods be ready?
- When can the supplier release the cargo?
- How long will collection take?
- What export documentation is required?
- Which airport offers the most practical routing?
- Are direct or connecting services available?
- How long will customs clearance take?
- How will the shipment reach its final destination?
- What happens if the preferred flight is cancelled or rolled?
This approach gives your freight forwarder something much more useful than simply, “We need this shipped urgently.”
It creates a clear logistics requirement.
Is air freight more expensive than sea freight?
Generally, yes. Air freight normally costs more than ocean freight, particularly for larger and heavier shipments.
But comparing the freight rate alone can be misleading.
A lower transport cost doesn’t necessarily mean a lower overall supply chain cost if the slower service causes stock shortages, production downtime, missed sales or contractual problems.
The right comparison is the total cost of meeting the delivery requirement.
For high-value, lightweight, urgent or production-critical cargo, air freight can therefore make commercial sense even when ocean freight is available.
For large volumes with flexible delivery dates, ocean freight may remain the more appropriate option.
The answer depends on the shipment.
