Can fuel surcharges go down as well as up?

Yes — since they typically track underlying jet fuel cost, a surcharge reviewed periodically can decrease if fuel prices fall, not just increase. It isn't a one-directional ratchet.

Does booking further in advance guarantee a lower price?

It generally improves the odds of securing capacity before a peak crunch tightens pricing, but it doesn't guarantee the lowest possible price — market conditions can shift in either direction between booking and fly date on the components not locked into the original quote.

Are minimum booking lead times affected by peak season?

Yes — carriers often need more lead time during peak periods given tighter capacity. See our minimum booking lead times guide for how that shifts specifically.

Peak Season and Fuel Surcharges, Explained

The quoted base rate is rarely the full cost — fuel, security, and peak season capacity surcharges layer on top, and they move independently of the base rate itself.

What actually moves peak season pricing

Three separate variables, not one price

Air freight pricing typically breaks into a base rate plus separate surcharges: a fuel surcharge (FSC) that tracks jet fuel cost and is usually adjusted periodically rather than fixed for the life of a contract, and a security surcharge (SSC) covering security screening costs. Both move independently of the base rate and of each other.

Peak season pricing is a distinct, capacity-driven phenomenon rather than a formal surcharge line item on most lanes — when available cargo capacity tightens relative to demand (commonly around Q4 in many global markets, tied to holiday retail restocking and manufacturing cycles specific to the origin), carriers and forwarders adjust pricing upward to reflect scarce space, sometimes on short notice.

Toy, garment, and footwear shippers on this corridor are especially exposed to peak season timing, since their retail deadlines are fixed and non-negotiable — see our toys & games and garments commodity pages for how that plays out on those specific categories.

Planning Note

Fuel and security surcharges are usually reviewed periodically, not fixed for the life of a quote

Confirm whether a quoted rate is all-in or base-plus-surcharges, and how frequently the surcharge components are reviewed, before treating an earlier quote as still valid for a later booking date.

General industry practice regarding fuel and security surcharge structures. Confirm current specific surcharge levels directly with your carrier or forwarder at time of booking.

Worked example

A worked example: booking ahead of a peak window

Take a garments shipment intended for a fall retail launch, where the shipper is deciding between booking early or waiting closer to the ship date.

Booking well ahead of the peak capacity crunch locks in space before carriers reduce allotments to forwarders and raise pricing in response to scarce capacity — this is a real, practical advantage distinct from simply hoping for a lower quoted rate later.

Even with space booked ahead of time, the fuel surcharge component can still move between booking and flight date if the carrier's surcharge is reviewed on a periodic cycle — UAL confirms which components of a quote are locked and which are subject to later adjustment before a client commits to a ship date.

What UAL confirms in a quote

We break out base rate, fuel surcharge, and security surcharge separately rather than bundling them into one number, and flag which components are subject to change before a shipment's actual fly date.

Frequently asked questions

No — timing and severity vary by origin, destination, and the specific retail/manufacturing cycles driving demand on that route. Confirm the expected peak window for your specific corridor and commodity rather than assuming a generic global calendar applies uniformly.
