Square Insights Sea & Air: From Emergency Option to Standing Strategy — Multimodal Freight in the 2026 New Normal

Registration dateMAY 19, 2026

When Route Disruption Becomes the Norm, What Are Your Options?

Key Takeaways
  • Red Sea risk and Suez Canal disruptions that began in 2023–2024 have become entrenched 'New Normal' conditions by 2026 — no longer temporary emergencies but standing operating constraints.
  • Sea & Air is a multimodal solution combining ocean and air freight by segment. Once used as an emergency measure, it is now being integrated as a standing strategic option.
  • The flagship example, Maersk Sea-Air, cuts transit time by 20–40% vs pure ocean and cost by 10–20% vs pure air freight.
  • This is fundamentally different from 'Sea to Air' (full mode conversion). Sea & Air mixes ocean and air across different segments of the same shipment.
  • Liability complexity — the structural risk of multimodal freight — is resolved through integrated platforms with single-contract, single-counterpart models (such as Cello Square).

2026: Red Sea Risk Is Not a Temporary Issue — It Is the New Normal

01

The Red Sea risk that began in late 2023 remains structurally unresolved as of 2026. Major Asia-Europe routes continue to rely heavily on the Cape of Good Hope detour, with 7–14 additional transit days and elevated war-risk insurance premiums now embedded as baseline cost structure. For shippers, 'waiting for things to normalize' is no longer a viable strategy.

This shift has fundamentally repositioned Sea & Air. What was once an emergency card pulled during route blockages has now become a standing component of operating portfolios. Global manufacturers and e-commerce sellers are formally including Sea & Air options in their monthly and quarterly transport plans.

📌 Three Entrenched Conditions as of 2026

Red Sea / Suez risk: Asia-Europe route delays have become constants. Expectations of 'return to normal operations' have largely faded.
Carbon Border Adjustment (CBAM): EU's full enforcement phase is underway. High-carbon ocean routes directly affect export cost structure.
AI logistics visibility now mandatory: Without real-time tracking, incident response lags by days, which cascades into stockouts.

What Is Sea & Air? — The Critical Difference From 'Sea to Air'

Sea & Air is a multimodal approach where cargo moves by ocean from origin to a transshipment hub, then switches to air from the hub to the final destination. Because only part of the route uses air, total cost is lower than pure air — and because part of the route uses air, total transit time is shorter than pure ocean.

Sea to Air vs Sea & Air — Not the Same Thing

Aspect Sea to Air (Full Conversion) Sea & Air (Multimodal)
Concept Full switch from ocean to air Ocean + air combined by segment
Decision timing Mode choice before shipment Designed as standing option from planning stage
Flow A (ocean) → B OR A (air) → B A (ocean) → Hub → B (air)
Trigger Ocean rate surge, lead-time risk Structural route risk + speed-cost balance
Cost Full air freight Blended (above ocean, below pure air)
Transit time Air-level (around 5 days) Between ocean and air (around 15–25 days)
Representative products Custom per forwarder Maersk Sea-Air, DHL Sea-Air

How Transshipment Works — The Customs-Bonded Corridor

At the heart of Sea & Air is the customs-bonded corridor that connects ocean and air at the transshipment hub. Cargo arrives at the port, then moves to the airport in bonded (uncleared) status, and is loaded onto the aircraft after security screening. Keeping this transition within 24 hours is what preserves the time advantage of Sea & Air.

Industry Applications — Where Sea & Air Is Being Used

Sea & Air has taken root across diverse industries. What they share is a 'middle-ground' need — cargo that ocean can't deliver in time, but that can't absorb full air-freight cost.

Industry Representative case Why Sea & Air fits
Automotive parts Sweden → Brisbane (Australia) Prevents production line stoppage. Ocean is too slow; full air is volume-constrained.
Retail & lifestyle Colombo → Cairo Maersk pilot case. Seasonal inventory replenishment.
Pharmaceuticals & perishables Asia → Europe / Middle East Must arrive within expiry window. Ocean is risky; air is costly.
Urgent manufacturing parts Asia → Europe · North America Semiconductor equipment, machine spares. Line stoppage costs run into hundreds of thousands USD.
E-commerce Asia → Europe · Australia Black Friday and Christmas replenishment. B2C peak season response.

Sea & Air Routes by Major Hub

The effectiveness of Sea & Air depends on the hub location and its connected infrastructure. For Asia-origin freight, Salalah and Dubai Jebel Ali are the most heavily used hubs.

Hub Covered routes Key destinations Notes
Salalah (Oman) Asia → Middle East, Africa, Europe Cairo, Nairobi, Frankfurt Maersk's first multimodal pilot hub
Dubai Jebel Ali Asia → Europe, Africa, North America Amsterdam, Johannesburg, New York World's largest transshipment hub
Singapore Intra-Asia → Europe Frankfurt, London Largest transshipment base in Asia
Incheon Asia → North America, Europe LA, Frankfurt Korean export hub; multimodal trials

Five Scenarios for Including Sea & Air in Standing Strategy

  • When Route Risks Are Structural, Not Temporary
    Routes like Red Sea / Suez, where segment risk has become entrenched, can re-intensify at any time. Having Sea & Air pre-designed in your operating portfolio enables instant response when risk escalates.
  • Peak Season Capacity Shortages
    Year-end and volume-peak seasons consistently produce ocean capacity shortages on specific routes. Including Sea & Air in your contract structure automatically diversifies peak-season capacity risk.
  • When Production-Line Continuity Is Critical
    For automotive parts and semiconductor equipment, where delay means massive line-stop costs, Sea & Air brings lead times close to air-freight levels while keeping total cost below full air.
  • E-Commerce Peak Season Replenishment
    Sellers racing to restock for Black Friday or Christmas can receive inventory in less than half the time of ocean freight with Sea & Air.
  • Time-Sensitive Cargo (Pharmaceuticals, Perishables)
    For cargo with expiration dates or freshness requirements — too urgent for ocean but not strictly requiring air-level speed — Sea & Air is optimal.

The Hidden Risk in Multimodal Freight — Liability, and How to Solve It

The biggest operational risk in Sea & Air is not cost or speed — it is liability complexity. When different contracting parties handle the ocean leg, the transshipment hub, and the air leg, it becomes unclear whom to claim against when cargo is damaged or delayed.

⚠️ Three Liability Risks Shippers Face in Multimodal

Contract fragmentation: Ocean forwarder, hub operator, and air forwarder each have separate contracts. Proving 'where did the damage occur' is difficult.
Visibility gaps: Different tracking systems per segment create blind spots at the transshipment point.
Claim delays: Inter-party liability disputes can take weeks or months, delaying insurance payouts.

Five Checkpoints Before Choosing Sea & Air

  • Hub selection: Connectivity to origin and destination; transit time between ocean and air (under 24 hours recommended)
  • Bonded corridor availability: Can cargo move port → airport without clearance delays?
  • Cargo characteristics: Volumetric and weight limits for air segments; special cargo handling (hazardous, refrigerated)
  • Total cost simulation: Ocean freight + transshipment + air freight + ancillary costs, compared side-by-side
  • Contract structure & liability: Does the provider offer single contract, unified visibility, and a dedicated counterpart?

Sea & Air Decision Checklist

Check Key question Judgment
Route status Does our route carry structural risk (Red Sea, Suez, etc.)? If yes → include as standing Sea & Air portfolio option
Time sensitivity Must cargo arrive faster than pure ocean, even if not as fast as air? If yes → good fit
Cost headroom Can we absorb full air freight cost? If not → Sea & Air is advantageous
Cargo profile Are volume and weight within air-freight parameters? If no → keep pure ocean
Contract structure Is single contract, integrated visibility, and dedicated counterpart provided? If not → liability risk increases

Frequently Asked Questions

Q. Are Sea & Air and Sea to Air the same thing?
A. No, they are fundamentally different. Sea to Air means a full conversion from ocean to air freight. Sea & Air is a multimodal combination — ocean for part of the route, air for another part. For example: an Asia-to-Europe shipment under Sea to Air moves entirely by air, but under Sea & Air it might move by ocean to a Middle East hub, then by air from the hub to Europe.
Q. How much cheaper is Sea & Air compared to pure air freight?
A. Per Maersk's official announcement, Sea & Air is 10–20% cheaper than pure air freight. The exact savings vary by origin-hub-destination combination, cargo characteristics, seasonality, and transshipment cost — so actual quote comparisons are the most reliable way to evaluate.
Q. How much faster does Sea & Air arrive?
A. Transit time is 20–40% shorter than pure ocean. If pure ocean from Asia to Europe takes 30–35 days, Sea & Air typically delivers in about 18–25 days. Slower than full air (5–7 days) but significantly faster than pure ocean.
Q. Why include Sea & Air as a standing option in 2026?
A. Because route risks like Red Sea and Suez disruptions have become entrenched structural conditions rather than one-off events. The 'wait until normal operations resume' strategy is no longer viable — and global manufacturers and e-commerce sellers are already formally including Sea & Air options in their monthly and quarterly transport plans.
Q. How is the liability problem in multimodal resolved?
A. The key is choosing an integrated platform that provides single-contract, single-liability structure. Services like Cello Square — which handle the entire ocean-transshipment-air flow under one contract, assign a dedicated counterpart, and provide real-time tracking through a unified dashboard — eliminate the fragmentation problem at its root.
Q. What types of cargo are best suited for Sea & Air?
A. Automotive parts, pharmaceuticals, e-commerce inventory replenishment, perishables, and machine spare parts — cargo that is urgent but can't justify full air cost. Low-value bulk cargo or cargo with ample lead time is still better served by pure ocean.
