Air freight or sea freight? How to actually decide.
A practical way to make the call, without guessing.

The short version: air freight costs more per kilo but moves in days. Sea freight costs less per unit of volume but takes weeks. Almost every other consideration in this guide is really just a variation on that one trade-off.
Start with one question
Would a two to four week delay cost you more than the difference in freight charges? If yes, air freight usually pays for itself: a missed sales window, a stalled production line waiting on a part, or a contractual deadline can easily be worth more than the extra you'd pay to fly the cargo instead of shipping it by sea. If a delay is merely inconvenient rather than costly, sea freight is very often the more economical choice, especially at larger volumes.
The real question is rarely "which is cheaper." It's "what does a delay actually cost me?"
When air freight is the right call
Time-sensitive orders, urgent replacement parts, perishable or seasonal goods, and anything where the value of the cargo is high relative to its weight all tend to favor air. Air freight is also worth it when your supply chain has already absorbed a delay elsewhere and you need to recover lost time somewhere else in the process.
When sea freight is the right call
Large or heavy shipments, restocking on a predictable schedule, and goods where per-unit shipping cost matters more than speed all tend to favor sea. If you can plan two to six weeks ahead (typical for the lanes covered on our Routes page), sea freight usually offers meaningfully better economics per unit shipped.
You don't have to choose only one
Mixed shipments are common and often the smartest option: send the portion of an order that's genuinely urgent by air, and let the bulk of the volume follow by sea. This is particularly useful for a product launch, where an initial small batch needs to arrive fast and the main stock can follow at a lower cost.
A simple way to decide
Ask three questions: How soon do I actually need this? What does a delay cost me in real terms? And is the volume large enough that sea freight's per-unit savings are worth the wait?
