Understanding Peak Season Surcharges in Air Freight and How to Prepare

For small to medium-sized enterprises (SMEs), air freight is a critical lifeline—especially during peak demand periods like holidays, promotional seasons, or global trade surges. But when demand spikes, so do costs. The biggest culprit? Peak season surcharges in air freight.

If you rely on air cargo to move goods quickly and meet customer expectations, these additional charges can disrupt your supply chain, stress your budget, and impact overall business performance. Fortunately, there are smart ways to prepare and mitigate their impact.

What Are Peak Season Surcharges in Air Freight?

Peak season surcharges (PSS) are temporary fees added by air carriers during high-demand shipping periods to offset increased operational pressures.

When Do They Apply?

Carriers typically impose surcharges during:

• Major holidays (e.g., Christmas, Lunar New Year)
• Key e-commerce events (e.g., Black Friday, Singles’ Day)
• Global trade disruptions or congestion
• High agricultural or retail shipping seasons

Why Do Surcharges Exist?

Several factors drive PSS:

• Capacity shortages: When demand exceeds available aircraft space, surcharges help prioritize urgent shipments.
• Increased fuel and labor costs: Extra staffing and overtime are often required to meet peak demand.
• Ground congestion: More cargo at airports means longer handling times, storage fees, and ground crew fatigue.

Essentially, these fees allow carriers to manage high-volume operations while maintaining service levels.

Why Do Carriers Apply These Surcharges?

The logic behind surcharges isn’t just profit—it’s logistical survival during crunch periods.

1. Balancing Supply and Demand

Air freight capacity is limited. Surcharges deter non-critical shipments and make space available for businesses willing to pay for urgency.

2. Offsetting Operational Strain

Carriers face increased costs for:

• Additional labor and equipment
• Extended operating hours
• Fuel price volatility

Surcharges help absorb these costs without raising base rates permanently.

3. Prioritizing Critical Shipments

By charging more, carriers ensure they can move high-value or time-sensitive cargo faster—like perishables, electronics, or seasonal products.

Hidden Costs and Risks for SMEs

For smaller businesses, these surcharges often arrive without warning—and without flexibility in the budget.

Here’s what SMEs face if unprepared:

• Unplanned budget overruns: Surprises in freight bills can erode already thin margins.
• Higher per-unit costs: Especially damaging for low-margin or price-sensitive goods.
• Lost sales opportunities: Products delayed or priced too high may miss their market window.
• Overbooked flights: Even if you’re willing to pay, capacity may be gone without advance booking.

Impact on Supply Chain Performance

Beyond direct costs, peak season surcharges can trigger downstream operational challenges.

Strain on Cash Flow

You may need to prepay for air freight or shift budgets away from other departments just to cover urgent shipments.

Inventory Gaps

Delays caused by capacity bottlenecks can lead to stockouts, leaving shelves empty or customers disappointed.

Damaged Customer Relationships

Late deliveries can cause missed holidays, promotions, or events—damaging trust and retention.

How to Prepare and Minimize the Impact

Preparation is your best defense. Here’s how SMEs can reduce the financial and operational shock of peak season surcharges:

1. Book Early

Advance bookings (4–6 weeks ahead of peak) give you:

• Lower rates
• Guaranteed space
• Time to reroute if needed

Early planning avoids the scramble and inflated costs that come with last-minute shipments.

2. Consolidate Shipments

Instead of frequent small shipments:

• Combine orders into full pallet or container loads
• Lower handling and per-unit charges
• Reduce customs entries and fees

It’s more efficient and cost-effective when volume allows.

3. Negotiate Long-Term Agreements

If you have predictable seasonal volume:

• Lock in space and rates with freight forwarders or carriers
• Avoid sudden price hikes during peak
• Get priority placement on oversubscribed routes

Strong relationships pay off when others are scrambling for access.

4. Use Flexible Routing and Multimodal Options

Not all cargo needs the fastest route:

• Consider regional or secondary airports
• Use a mix of air + road, or air + rail, where practical
• Build in flexible lead times for non-urgent SKUs

This spreads risk and lowers cost.

5. Forecast Demand Accurately

Align logistics with realistic projections:

• Use sales history and market trends to guide order timing
• Prioritize fast-moving or high-margin items for air freight
• Avoid overstocking due to panic-driven shipping

Demand planning makes shipping smarter—not just faster.

6. Leverage Real-Time Tracking and Alerts

Visibility lets you:

• Spot delays early
• Proactively communicate with customers
• Re-route in real time if disruptions occur

Digital tools are essential in fast-moving peak conditions.
