Air Cargo Rebounds in September as MESA and Fuel Costs Bite

Global air cargo found its footing in mid-September 2026. After the annual Labour Day dip, chargeable weight extended its winning streak to four consecutive weekly gains, with the global 2% week-on-week rise confirming that the Labour Day slowdown has cleared. Compared with the same week in 2025, worldwide volumes were 8% higher. The market is recovering, but it is not recovering evenly.

The headline numbers look solid. Average worldwide spot rates sat at $3.45 per kilogram, running 33% above year-earlier levels. Full-market rates were up 24% year on year. The Baltic Air Freight Index (BAI00) gained 0.9% over the seven days to 21 September 2026, leaving it 20.9% higher than a year ago. Beneath those numbers, the market is splitting by tradelane, by region, and by carrier.

North America Drives the Rebound While MESA Volumes Slip

North America delivered the strongest week-on-week volume performance, rising 14% as post-holiday freight returned to the network. Year on year, North American tonnages were up 8%. Chicago outbound rates edged up 1% week on week and stood 45.7% above year-earlier levels. The picture on spot rates was more cautious: North America spot rates fell 4% week on week, even as volumes surged.

The Middle East and South Asia (MESA) region told a different story. Volumes fell 4% week on week. Bangladesh shipments dropped 17% week on week. Sri Lanka volumes fell 10% week on week. Traffic from India fell 5%. MESA volumes to the United States fell 5% week on week, though MESA traffic to Europe edged up 1%. Despite the volume weakness, MESA full-market rates remained 49% above year-earlier levels, and spot rates were 52% higher year on year. That gap between volume and rate performance is consistent with constrained capacity on affected routes, as airspace restrictions have limited available cargo space.

Jet Fuel Costs Double Year on Year, Squeezing the Rate Equation

The biggest structural pressure on the market right now is fuel. Jet fuel costs rose 116.5% year on year to 18 September, according to the IATA Jet Fuel Price Monitor. The scale of that increase is significant for carrier cost structures. For carriers already managing rerouted services due to Middle East airspace restrictions, a doubling of fuel costs changes the economics of every route decision. Fuel surcharges follow. Rate floors get reset. Shippers paying spot rates are absorbing some of that pressure, whether they see it itemised or not.

The rate picture at lane level is mixed, not uniform. London Heathrow outbound jumped 10.0% week on week, leaving it 11.4% above year-earlier levels. Shanghai outbound gained 0.6% week on week and stood 19.7% higher year on year. Hong Kong outbound added 0.3% week on week, up 19.6% year on year. Frankfurt bucked the trend, dropping 3.4% week on week, though it remained 21.1% higher year on year. Africa full-market rates rose 6% week on week to $2.47 per kilogram. Africa spot rates recorded the largest weekly spot-rate increase at 7%. MESA and CSA spot rates each eased slightly week on week. No single directional story covers the whole market.

China-Europe Rates Recover as De Minimis Impact Works Through

China-Europe airfreight rates strengthened week on week after a period of. The EU de minimis exemption ended in July 2026, reducing the volume of small parcels moving from China into Europe. That shock has been working through the market. As volumes stabilised, rates on the corridor firmed. China-US rates slipped slightly week on week but remained well above year-earlier levels. The adjustment is ongoing rather than concluded.

Asia Pacific origins led year-on-year tonnage growth at 11%, ahead of North America at 8% and Europe at 6%. MESA and Central and South America each posted 2% year-on-year growth. Full-market rates by region: MESA up 49%, Europe and Africa each up 26%, Asia Pacific up 21%. Airspace restrictions and airport bottlenecks in the Middle East have constrained capacity on MESA routes, which may account for the elevated MESA rate premium. Christopher Braun, Forto’s director freight, said: ‘For shippers, the global average is less important than whether sufficient capacity with the required service level is available on the specific tradelane they need, at the right time. Early bookings and flexible routing remain the best protection against capacity shortages and sudden price spikes.’

CSN Perspective: Lane-Level Volatility Is the Real Story

The aggregate indices are useful context. They are not a quoting tool. A 0.9% weekly gain in the BAI00 tells you very little if you are moving freight from Dhaka to Chicago, where Bangladesh volumes dropped 17% week on week and MESA-US capacity is under active pressure. The shippers and forwarders who manage this market well are tracking lane-level data, booking earlier, and holding alternative routing options. This approach reflects sound freight management practice rather than a new strategic posture.

Fuel at 116.5% above year-earlier levels is not a temporary line item. It reshapes carrier cost structures. It changes which routes carriers prioritise and which they cut or reroute. For independent forwarders, that means access to real capacity data at the lane level matters more than ever. Relying on outdated rates or single-source data increases the risk of margin erosion in a volatile market.

Frequently Asked Questions

Why did global air cargo volumes rebound in the week ended 20 September 2026?

The 2% week-on-week rise followed the annual Labour Day freight dip. North America accounted for most of the rebound with a 14% week-on-week volume increase as normal shipping patterns resumed after the holiday period.

Why are MESA air cargo rates so high despite falling volumes?

Middle East and South Asia volumes fell 4% week on week, but MESA spot rates were 52% above year-earlier levels. Airspace restrictions and airport bottlenecks linked to regional tensions are constraining available capacity, which keeps rates elevated even when demand softens.

How much have jet fuel costs risen and what does it mean for airfreight rates?

Jet fuel costs rose 116.5% year on year to 18 September 2026, according to the IATA Jet Fuel Price Monitor. Higher fuel costs increase carrier operating expenses, which feeds into fuel surcharges and sets higher rate floors across many lanes.

What caused China-Europe airfreight rates to strengthen in September?

The EU de minimis exemption ended in July 2026, which reduced small parcel volumes from China to Europe. As volumes stabilised following that initial shock, rates on the China-Europe corridor firmed week on week in September.

Which outbound routes showed the strongest rate growth in the week to 21 September?

London Heathrow outbound jumped 10.0% week on week. Chicago outbound gained 1% week on week and stood 45.7% above year-earlier levels. MESA spot rates remained 52% above year-earlier levels overall, reflecting persistent regional capacity pressure.
