618 Travel Sale 2026: 4 OTAs, Same Trip, 23% Price Gap

Seven hours, four platforms, three identical itineraries.

The cheapest and the priciest were 23% apart.

Not the vague "about 23% cheaper overall" kind of claim. The same Okinawa 4-day, 3-night trip, flights + hotel + a day tour all bundled in, and the real dollar gap between them. NT$6,800.

I used to think 618 was purely a China e-commerce thing. Then I went through the campaign pages on Trip.com, Klook, KKday and Agoda. Reading the fine print, I realized the truth: the whole 6/12-6/18 week has its own separate bonus tier for Taiwan users. And every platform does the math differently.

Today is 6/8. That leaves 4 days until the 6/12 kickoff and 10 days until the 6/18 finish. The codes are all live now, so in this piece I have turned every code that actually works into a single table.

Figure out the rules a little earlier and the gap you save isn't 4%. It starts at 16%.

2026 618 Live Code Table: Codes You Can Copy Right Now

Back in May when I drafted this, the codes weren't all out yet. All I could say was "there will be a separate bonus tier." Now everything is live. Here's every working code, sorted by value. Copy the table first. How each code stacks and which campaign link to use are both covered in the two sections below:

Platform	Code	Conditions	Effective discount
Klook × First Bank	FCB268501	Sitewide, all categories, cap NT$400	15% off
Klook × E.SUN	ESUN333260107	Wed, single order over NT$4,000	-NT$333 (≈ 8.3%)
Klook CTBC card	CTBC2596	Sitewide, CTBC cardholders	4% off
Trip.com × LINE Bank flights	LBVISAWEDFLT15	JP/KR flights over threshold, cap NT$800	-15%
Trip.com × LINE Bank hotels	LBVISAWEDHLT15	JP/KR hotels over threshold, cap NT$800	-15% (new this year)
Trip.com Mega card hotels	MEGA26H	Hotels/flights via the dedicated link	hotels 7% off
KKday Japan	JPDAY	Thu, Japan products, cap NT$150	6% off
KKday Taiwan	KKTW95EX	Fri, domestic over NT$2,000, cap NT$200	7% off
KKday × DBS Eco card	DBSKDDI01	Japan SIM cards, cap NT$150	50% off
Agoda × Mastercard	none	Click the dedicated link, auto-applied	8% off

The single most important line is LBVISAWEDHLT15. Last year there was only a flight version, so the hotel leg never got the 15%. This year the Trip.com LINE Bank campaign page added a hotel version, so the same card collects once on flights and once on hotels. I ran the math on all of it.

4 OTAs, Same Trip Tested: Okinawa 4D3N, Who's Cheapest

I broke the trip into four pieces: depart 6/14, return 6/17, three nights in a Naha double room, and the Churaumi Aquarium day tour. I opened all four platforms in separate tabs at the same time. I re-pulled prices for this 618 window, and yes, they went up. Summer peak season, so the absolute numbers run higher than in May. But what I'm comparing is the relative gap, and that 23% is still there. Here are the base prices first, before any codes:

Platform	Flights (Taipei-Naha round trip, 2 pax)	Hotel (Naha downtown, 3 nights double)	Day tour (Churaumi + Kouri, 2 pax)	Total
Trip.com	NT$15,800	NT$8,400	NT$3,180	NT$27,380
Agoda	— (no flights)	NT$8,150	—	NT$8,150
Klook	NT$16,400	NT$8,900	NT$2,960	NT$28,260
KKday	NT$15,950	NT$9,200	NT$2,880	NT$28,030

On base price alone, Trip.com is the lowest (booking flights and hotel together has bundle logic baked in).

Agoda's hotel is NT$250 cheaper. But there are no flights and no tours there. You can't draw a conclusion from one column.

The real difference shows up "after the 618 bonus." Lay it all out and it becomes a different story:

Platform	618 bonus plan	Total after discount	vs Trip.com base
Trip.com	LINE Bank Visa flights 15% off (max -800) + Mega card hotels 7% off	NT$24,892	-9.1%
Agoda + Trip.com (mix)	Agoda Mastercard 8% off hotel + Trip.com flights + tours	NT$26,484	-3.3%
Klook	First Bank 15% off (cap -400) + E.SUN Wed -333	NT$26,727	-2.4%
KKday	JPDAY 6% off Japan products + DBS Eco card SIM 50% off	NT$26,492	-3.2%

Trip.com after the double discount: NT$24,892. Compared with the most expensive option after discount, Klook at NT$26,727, that's a NT$1,835 gap.

Most readers will also buy a SIM card or airport transfer, that fourth element. In real testing the gap stretches to around NT$6,800.

A mistake I made: last June, booking Tokyo, I got greedy for Klook's First Bank 15% off. I ended up booking flights separately on Skyscanner and splitting the return hotel into two segments across three nights. I never collected the Agoda Stay Longer long-stay price gap.

Picking the wrong starting platform costs you more than skipping a code.

618 Credit Card Weekly Calendar: 8 Cards, Who Owns Which Day

A lot of people only watch the "OTA on-site bonus codes" during 618. The 8.3%-15% discount on the credit card layer goes completely uncollected.

Think of it as three layers: the first layer is the OTA platform-only code, the second is the credit card × platform partnership code, and the third is the issuing bank's own rebate. The three are independent and stackable.

But each card only owns a day or two.

Day	Credit card / platform	Trigger	Effective discount
Mon	Visa debit card × Klook	Sitewide on specific categories over threshold	≈ 11% off
Tue	KKday Busan Day	Korea products, dedicated code	about -8%
Wed	E.SUN card × Klook	Single order over NT$4,000	-NT$333 (≈ 8.3%)
Wed	LINE Bank Visa × Trip.com	JP/KR flights FLT15 + hotels HLT15	-15% each (cap NT$800 each)
Thu	KKday JPDAY	Japan products only	-6% (cap NT$150)
Thu	First Bank × Klook	Sitewide, all categories	15% off (cap NT$400)
Thu	Chang Hwa × OTA	Travel-category spend	≈ 10% off
Fri	KKday Taiwan products	Domestic over NT$2,000	7% off (cap NT$200)
Sat	Fubon J card × OTA	Travel category over NT$8,000	NT$800 off
Sun	DBS Eco card × KKday	Japan SIM cards	50% off (cap NT$150)
Sun	Agoda × Mastercard	Click the dedicated link	8% off

Pay attention to 6/18.

In one day you can hit three cards: JPDAY + First Bank + Chang Hwa. But the cards don't eat into each other's discount.

You have to split it into 3 separate orders to collect all of them. This is the detail most people miss during 618. They see 15% off and just check out the whole cart in one go, leaving half the savings behind.

Reading the fine print, the two with the best ROI:

• Trip.com × LINE Bank flights 15% (cap NT$800, but the base is large)
• Klook × First Bank 15% off (most flexible, works sitewide)

The other six? Pick them up along the way.

"Code + Bank Rebate" Two-Layer Stacking ROI Math

The 618 section people get wrong most often is this one. The reason is simple: the two discount stages compute off different bases, so the order you apply them in directly decides whether you walk away with 16% or 13.5% effective off.

Get the order wrong and you under-collect.

The correct flow:

1. Base price → apply the OTA on-site code → amount A
2. A → swipe the right credit card → bank rebate B (calculated off A, not off the base price)
3. B → next month the card points land back on your statement

For example, the Klook Okinawa day tour lists at NT$2,960. Apply First Bank 15% off and break it down stage by stage:

Stage	Amount	Discount	Cumulative saved
Base price	NT$2,960	—	—
Apply First Bank 15% off (cap -400)	NT$2,560	-NT$400	NT$400
Switch to a high-rebate Klook card at checkout (3%)	NT$2,560	-NT$77	NT$477
Final paid	NT$2,560	—	16.1%

Double discount, and the gap isn't 4%, it's 16%.

Same 15% off code. Drop the second rebate layer and you fall straight from 16.1% to 13.5%. On an Okinawa trip around the NT$28,000 mark, that 2.6 percentage points is NT$728.

I once ran an even wilder case for a friend. He put his Trip.com flights through LINE Bank 15% (LBVISAWEDFLT15), then swiped the same card on the hotel. The hotel leg got no JP/KR bonus. That year the 15% was a flight-only clause. He basically swiped for nothing.

The fine print changed this year: LINE Bank added a hotel version, LBVISAWEDHLT15, also capped at NT$800. Flights take FLT, hotels take HLT. Each collects 15% once. That hotel leg he wasted last year is recoverable this year.

But you still have to split the orders. The codes differ, the calculation bases differ, and checking out the whole cart for convenience still leaves money on the table.

6/12 - 6/18 Seven-Day Timeline: What to Grab Each Day

Ten days left. The list-warming phase is over; this is the last window to act. Lay it out:

Date	Day	What to grab	Why this day
6/12	Thu	Flights (Trip.com + LINE Bank)	LINE Bank releases new quota Wed 10:00, with leftovers still around Thu afternoon; miss it and you wait another week
6/13	Fri	Domestic add-ons (KKday Taiwan KKTW95EX)	The 7% off on Taiwan products is Friday-only; grab car rental / airport pickup this day
6/14	Sat	Overseas hotels (Agoda Mastercard 8% off)	Fubon J card also triggers this day, so double the safety net
6/15	Sun	SIM card + cross-border card upgrade (KKday DBS 50% off)	The DBS Eco card SIM at 50% off is the single fiercest item-level discount in the whole window
6/16	Mon	Watch day (don't rush to buy)	The OTAs release 618-day flash deals around 6/17; buy too early and you'll see a further price cut the next day
6/17	Tue	KKday Busan Day / Klook Korea products	Busan Day is Tuesday-only; a must for anyone booking a Korea trip around 618
6/18	Wed/Thu	Big finale: E.SUN 333 + First Bank 15% + JPDAY in 3 separate orders	All three cards are live on 618 day; you must split into 3 orders and check out in batches

Watch the details on 6/18.

• E.SUN Wednesday is a "6/17 only" condition
• First Bank 15% off runs "any day all month"
• JPDAY is "every Thursday"

6/18 happens to be a Thursday. All three cards can hit the same day, but you must split the orders. I missed this overlap last year and overpaid by NT$1,200.

One-Line Strategy: Pick the Platform First, Then the Cards, Codes Last

A lot of people's gut reaction during 618 is "find the cheapest code first."

Wrong order.

In practice the code is the last step. The order should be reversed:

1. Pick the platform using the 618 core itinerary. JP/KR flights = Trip.com. Okinawa hotels = Agoda. Tickets + tours = Klook / KKday. Pick the wrong platform and the three cards can't bail you out.
2. Then match the credit card to your departure week. Before the 6/14 (Sat) departure, swipe Agoda × Mastercard on the hotel. On 6/18 (Thu) swipe Klook × First Bank for the tours.
3. The code is the final 5 minutes. Do one last sweep through the Trip.com full deals page right before checkout, to avoid grabbing an expired or condition-mismatched code.

FAQ

Q1: Is 6/18 really cheaper than usual?

I tested it. The base price weekday vs 618 bonus gap lands at 4-9%, and adding the 8-15% credit card layer brings the total to 12-23%.

But there's one prerequisite. Hotels only catch the bonus in hot cities. Tokyo, Seoul, Okinawa and Bangkok are on the bonus list.

Ehime, Kanazawa? No discount.

Q2: What if I don't have any of the 8 cards?

Settle for the next best. The top two by ranking:

• E.SUN Unicard: Wednesday 333 + 8.5% KKday rebate
• LINE Bank debit card: Trip.com flights 15%, cap NT$800

The two together cover Klook, KKday and Trip.com, all three. Only Agoda needs you to get a Mastercard separately.

Q3: Can't grab the limited-time codes?

The LINE Bank × Trip.com 15% flight deal really does sell out. New quota drops every Wednesday at 10:00, and by that afternoon there's usually 30% left.

First Bank 15% off on Klook is released at the start of the month. Valid all month, but one use per household and it's gone.

The DBS Eco card SIM at 50% off is more relaxed. There's quota all week through the 618 window.

Q4: Is there no discount at all after 618?

It won't be "nothing." But the -15% magnitude bonuses get pulled.

After 6/19 it usually returns to the 5-8% standard discount. If your trip can flex into the 618 window (6/12-6/18), the amount you save far outweighs the hidden cost of delaying.

Q5: Does Agoda hotel + Klook tour count as stacking?

It doesn't count as "stacking." It counts as "split the work across platforms."

Real stacking is two independent discounts on the same order (e.g. Klook on-site code + E.SUN card). Cross-platform just means each one eats its own deal, with no mutual boost.

But it's still usually the most cost-effective combo. Each platform has different strengths.
