Sea or Air in the Last Quarter of 2026: How to Decide Without Guessing the Market

October is the critical month for importing SMEs that must decide how to supply their holiday sales and the start of January. Sea and air freight forecasts diverge, making the decision more complex than ever. In this article we analyze the most relevant indicators and provide a practical guide to choose the transport mode without relying on market luck.

Sea freight situation

The year has been volatile. At the end of February, the World Container Index from Drewry was around $1,919 per 40‑foot container. On July 9 it reached $4,639, the highest level since September 2024, driven by the Asia‑Europe route.

“The World Container Index reached $4,639 in July, its highest peak in two years.”

Since then, the index has stabilized around $4,400. In August, congestion at the port of Shanghai caused an average wait of 96 hours per vessel, a key data point when calculating delivery times.

Transit times have also lengthened: detours around the Cape of Good Hope add between 10 and 14 days to Asia‑Europe routes.

Air freight evolution

The air segment is growing modestly. According to IATA, demand in July rose 3.9 % year‑on‑year, while capacity increased 1.7 %.

“Aviation fuel reached $157 per barrel, 79.2 % higher than the previous year.”

This cost increase translates into higher rates: cargo yields remained 24.9 % above August 2025. Xeneta forecasts a moderate fourth quarter, without a peak season that would spike prices, but also without significant discounts as long as fuel stays high.

Two opposite readings for the fourth quarter

Analysts offer two co‑existing narratives:

• Fall narrative: many European importers advanced their high‑season purchases, which would reduce replenishment in November and push freight rates down.
• Caution narrative: the drop in imports between June and September does not mean Q4 demand has disappeared, only that it has been brought forward. It is recommended to negotiate sea cargo space in advance.

Both perspectives can be correct depending on route and sector. The key is to base the decision on your own criteria, not on assumptions.

How to choose the transport mode: five key questions

1. How many days of stock do you have? If you have weeks of cushion, sea is viable; if you only have days, air is indispensable. The sector sets the threshold at less than 10 days for air to arrive on time, while sea requires between 15 and 20 days door‑to‑door.
2. What is the relative value of the goods compared to their weight and volume? Air transport is justified for high‑value, low‑volume products (electronics, components, samples). For bulky, low‑value goods, sea freight protects the margin.
3. What is the cost of being late? A reference that does not arrive for Christmas loses value significantly compared with the same reference in October. Quantify that risk before comparing quotes.
4. Is it a one‑off shipment or recurring? Recurring volumes allow negotiating agreed rates. Xeneta indicates a trend toward flexible contracts that avoid being locked into fixed rates if the market falls.
5. What does the price actually include? Always request a breakdown between freight and surcharges. This practice, recommended by WTO‑MWW, enables full transparency when comparing sea and air.

Splitting the order: the hybrid option

Instead of choosing “all sea” or “all air”, many companies send the bulk of the order by sea and reserve the plane for critical or fast‑moving references. This strategy protects key sales without incurring the full cost of air freight.

The split should be based on margin, stock level and the calendar of each reference. Performing calculations with real data from your operation will guarantee a decision that matches reality.

Considerations for small parcels

From July 1 2026, shipments under €150 entering the EU from outside are subject to a €3 tariff per item category, plus a €2 handling fee per item, applicable no later than November 1 2026.

For urgent low‑quantity shipments, these charges can exceed the cost of the air transport itself. Consult your customs agent to confirm the exact accounting.

Action plan for the next two weeks

1. Take inventory of orders in transit or scheduled until year‑end, with a latest arrival date for each.
2. Request detailed quotes (freight + surcharges) for both sea and air for the tightest shipments.
3. Define now which references must go by plane and which can wait until January.
4. Negotiate with your freight forwarder contracts or rates with revision clauses, to adapt to possible market drops.
5. Include an extra cushion of days in the schedules; port congestion and detours rarely allow meeting the “theoretical” deadline.

There is no single answer for Q4 2026. What is clear is that the best strategy combines rigorous planning, transparent quotes and a ready‑to‑activate option B.
