Trip.com October discount code 3HAFLT3
Trip.com offers the Three Hours Before creator-exclusive flight discount code 3HAFLT3. There is no minimum spend, and it gives 3% off the airfare portion of a booking, up to KRW 12,000.
The booking period is October 1–30, 2026. Eligible flight departure dates can extend through December 31, 2027.
The discount code itself can be used until 11:59 PM on October 31, with up to 10 uses per account.
The code may not apply to some airlines or routes. It also requires booking after entering Trip.com through the designated affiliate link rather than through a regular Trip.com visit.
After comparing flight prices, you can use the Trip.com affiliate page to check whether the code applies to your booking.
KKday discount codes for October 2026
KKday has two Three Hours Before exclusive discount codes available during October. They can be used across KKday categories worldwide, from overseas hotels to tours and activities.
| Discount code | Minimum spend | Discount |
|---|---|---|
| 3HOURS260812K | KRW 80,000 | KRW 5,000 |
| 3HOURS26085K | KRW 200,000 | KRW 12,000 |
Both coupons are valid from October 1 through October 31, 2026. Check the final price of the product you plan to book, then choose the code whose minimum-spend condition matches your order.
KKday’s October offers can also be checked through the KKday monthly coupon pack.
Compare KKday’s general-use coupons too
There are also general-use coupons in addition to the exclusive codes. KKSUMMER3K gives KRW 3,000 off purchases of KRW 50,000 or more, while KKSUMMER6K gives KRW 6,000 off purchases of KRW 100,000 or more.
For example, if your booking total is KRW 80,000, compare the exclusive KRW 5,000 discount with any general coupon you are eligible to use and check the final discount amount.
Daegu Aquarium October special price and extra coupon
If you are planning an October trip to Daegu, KKday also has a Daegu Aquarium promotion. The promotion runs from October 2 through October 11, 2026.
A ticket normally priced at KRW 29,000 is available for KRW 19,900. Applying the exclusive code DGAQUA1 gives an additional KRW 1,000 discount when purchasing one admission ticket.
The promotion runs from 12:00 AM on October 2 until 11:59 PM on October 11. It has the shortest validity period among the discounts listed here, so check the dates first if you plan to visit.
The Daegu Aquarium offer can also be checked through the KKday monthly coupon pack.
Klook discount codes for October 2026
Klook has three discount codes based on your total purchase amount. The available discount increases as the qualifying purchase amount becomes higher.
| Discount code | Minimum spend | Discount |
|---|---|---|
| 세시간전260001 | KRW 50,000 | KRW 2,000 |
| 세시간전260002 | KRW 100,000 | KRW 3,000 |
| 세시간전260003 | KRW 200,000 | KRW 7,000 |
The codes can be used on Klook products across all countries except for certain excluded items, and they are valid from October 1 through December 31, 2026.
They can be used not only for October trips but also for advance bookings for November or year-end travel. Check your final booking total first, then apply the code that matches the minimum-spend requirement.
When browsing Klook, you can compare booking products and final prices through the Klook attractions and travel products page.
Which travel coupon should you check first?
If you already know what type of travel product you are booking, the coupon to check first will depend on the platform.
- Flight booking → Trip.com 3HAFLT3, 3% off airfare
- KKday tours and activities → Up to KRW 12,000 off depending on purchase amount
- Klook products → Up to KRW 7,000 off depending on purchase amount
- October trip to Daegu → Daegu Aquarium KRW 19,900 special price plus DGAQUA1 extra discount
Rather than deciding based only on the percentage or maximum discount, first confirm that the product you want to book is actually eligible.
What to check before applying a coupon
Some of these discount codes only work after entering the booking site through a designated affiliate link. Instead of saving only the coupon code, check the conditions on the linked affiliate page as well.
Entering a code does not mean every product will automatically receive a discount. Some products, airlines, or routes may be excluded.
Before payment, check that the discount has actually been applied on the final checkout screen. Promotions and coupons may change or end earlier than scheduled depending on the provider’s circumstances or budget.
October 2026 travel discount codes: key points
For flights, you can compare Trip.com’s 3% discount. KKday offers discounts of up to KRW 12,000, while Klook offers up to KRW 7,000 depending on the purchase amount.
Daegu Aquarium has a separate special price and an additional KRW 1,000 coupon from October 2 through 11. It is easier to choose if you decide your travel dates and booking amount first, then match them with each coupon’s requirements and validity period.
Most importantly, verify the actual discount on the final checkout screen. The same code may not apply depending on the product or booking conditions, so check once more before paying.
