How much will the fuel surcharge for a round-trip Incheon-Sapporo flight increase when booked in September compared to August?

Based on Korean Air's Sapporo route, the round-trip fuel surcharge for tickets booked in August is ~$68. For tickets booked in September, it will be ~$91, meaning the fuel surcharge alone will increase by ~$23.

I've heard that Sapporo flight prices might not drop in October but could actually increase. What's the reason for this?

This is because winter is Sapporo's peak season. With high demand for winter activities like snow, Otaru, ski resorts, the February Snow Festival, Christmas, and year-end holidays, flight prices often tend to rise over time.

What are the specific benefits of using Trip.com when booking Incheon-Sapporo flights?

1. Why You Should Book Your Incheon to Sapporo Flight Now

Let's get straight to the point: winter is peak season for Sapporo.

Typically, people wait, thinking "prices will drop in October," but

Sapporo is different.

With snow, Otaru, ski resorts, and the February Snow Festival,

winter demand surges, and prices often climb as time goes on.

Add Christmas and year-end holidays into the mix, and **flight prices can more than double compared to now.**

That's why for most winter Sapporo flights,

early booking is highly recommended.

With the added factor of the September fuel surcharge increase,

now is truly the best time to snag your winter flights at the most reasonable price.

In fact, as of August, a quick search for Sapporo flight prices shows them **already exceeding ~$483.**

During the Christmas season, they're already in the ~$621 range.

And guess what? Next month, with the fuel surcharge increase, those prices will go up by at least another ~$69.

First things first, I recommend checking the price for your travel dates.

2. How Much Will Fuel Surcharges Increase in September?

This is a crucial detail.

Airline fuel surcharges are based on the date of ticket issuance, not the travel date.

This means even if you travel in winter, if you book your ticket before the end of August, you can get it at the pre-increase price!

For tickets issued in September, international fuel surcharges will be at Level 21,

which is **7 levels higher than August (Level 14)** and the highest level applied in three months.

For example, according to Korean Air's announcement,

for the Sapporo route:

Round-trip fuel surcharge for tickets issued in August: **~$68.**

Round-trip fuel surcharge for tickets issued in September: **~$91.**

Issuance Period	August Issuance	September Issuance
Sapporo Round-Trip Fuel Surcharge	~$68	~$91
Fuel Surcharge Alone Increases by ~$23 🔺

With the fuel surcharge increasing by ~$23 alone,

for a family of four, that's a difference of over ~$90!

Information regarding fuel surcharge increases is typically posted on Korean Air's official website around the middle of each month,

and when Korean Air raises its rates, most other airlines follow suit, so it's a good idea to keep an eye on this.

You can book flights and hotels together

or even book them separately and still get discounts,

but I personally find that searching for them together makes it feel psychologically cheaper, so I tend to look at them all at once.

They're conveniently sorted by flight times and popular hotels, making it easy to choose.

If you don't find the price you want, you can simply set up price alerts and book later, which is why I use this feature so often.

🚨 Here’s a travel hack!

Many of you might also check Skyscanner,

but Skyscanner is a subsidiary of Trip.com,

so going directly to Trip.com can actually be cheaper.

Skyscanner often includes unfamiliar international flight websites in its results,

which is why I often end up checking directly on Trip.com anyway.

Starting with tickets issued in September 2026, international flight fuel surcharges will increase from level 14 to level 21.
