11.11 sale terms: what decides the price you actually pay

A December trip is on your calendar and you are weighing whether to book now or hold until 11.11 or 12.12. The decision turns less on the headline percentage than on four lines in the campaign's own published terms: the travel period it covers, the hours its codes and inventory stay open, what it excludes from the discounted price, and how many bookings each member may make. Read those four lines and the choice usually makes itself.

This is a reading guide to Klook's and Trip.com's own terms pages, not a deal round-up. One limitation shapes everything below: no first-party page reviewed here sets out what the 2026 11.11 or 12.12 campaigns will offer or when they run, so nothing here forecasts those dates. What can be compared is the structure of the rules a reader has to clear.

Why the wait became the default

Waiting has become a habit rather than a gamble, and The Straits Times reported in September 2026 on why. Klook ran only two double-digit sales in 2024, on 11.11 and 12.12, ran sales monthly from the 6.6 campaign in 2025, and is looking to run them monthly from 5.5 in 2026. Jeanette Ong, Klook's associate director of marketing, attributes part of that increase to Singapore travellers' longer booking windows, with more planning and booking trips months ahead. ^[1]

Ong also describes why the headline deals sell out: a deal's popularity shows in how fast it runs out, and among Singapore travellers the one-for-one deals are typically the most value-for-money but come in limited quantity. Scarcity is the point. A campaign whose inventory is released on a first-come, first-served basis is precisely the campaign where the small print decides whether you pay the discounted price or the full one. ^[1]

What a campaign window actually says

Start with the window. Trip.com's Singapore promo page, published 6 October 2026, lists a 10.10 promotion period running from 12:00am on 7 October 2026 to 11:59pm on 10 October 2026, Singapore time. Its published terms for a 'Buy 1 Get 1 Free from SIN to SHA' China Eastern promotion were narrower still: the promotion ran from 13:00 on 11 November 2025 to 23:59:59 the same day, and was open only to registered users over 18 using version 8.5.0 or above of the Singapore Trip app. That is about eleven hours. ^{[2] [3]}

The Klook side is similar in shape. A Klook 11.11 listing states that promo code 'MARKLEE' is effective from 12:00pm on 11 November to 11:59pm on 15 November, that each Klook user may use it once, and that the offer is limited to the first 100 checkouts. Trip.com's own 11.11 Mega Sale terms from November 2021 show how narrow these instruments get: the code was valid for one day only, payment had to be completed within 15 minutes, hotel inventory and one-for-one deals opened at 11:11am and 11:11pm on 11 November in limited quantities on a first-come, first-served basis, and the attraction one-for-ones were valid only on stated dates, limited to one booking per user ID. Those are that campaign's terms of that period. ^{[4] [5]}

Travel period, discount scope and what stacks

A campaign price is narrower still than its window. In those China Eastern terms, the travel period covered flights departing from 11 November 2025 to 30 June 2026, the two eligible round-trip economy tickets had to be purchased at the same time with the same departure and arrival time, and the 50% discount applied only to base fare and taxes. The same terms state that prices are dynamic according to availability and may change, and that if a booking is changed after the purchase is confirmed, the applicable discount may not be available or applied. ^[3]

To take a hypothetical case: a traveller with dates set for December 2025 would find them inside that published travel period, while someone planning a later departure would need to read the travel period of whichever promotion they hold for. ^[3]

The combining rules are where the two platforms' published pages diverge most. Trip.com's promo-code guide states that only one promo code can be applied per booking, while Trip Coins earned on bookings can be applied at checkout alongside a code; its October 2026 page adds that in most cases codes cannot be combined with other codes. The China Eastern terms go further, barring use alongside other discounts, cashback sites, loyalty programs, rewards, promotions, discounted and fixed-price items unless otherwise stated. Klook's Singapore terms for a 2024 PayNow campaign say privileges cannot be used in conjunction with other promotional programmes, offers, discount cards, vouchers or VIP privileges unless otherwise stated. ^{[6] [2] [3] [7] [8]}

Yet Klook's promo page, last updated 30 September 2026, states that its bank and card promo codes are stackable on top of Klook platform deals, with codes limited and refreshed monthly. The card you hold decides which rule applies. ^{[6] [2] [3] [7] [8]}

The route that needs no campaign date

Not every saving needs a sale date. Trip.com's October 2026 page publishes a 'Stay Trip Smart' promotion running from 3 September to 15 October with coupons dropping every Monday to Thursday at 2pm, and Klook's Singapore promo page lists codes refreshing on fixed weekdays. For a reader who can shop on a Wednesday, a dated weekly drop can be easier to catch than a sale that opens at midnight. The exposure sits on the other side of the ledger: Trip.com's terms, updated 25 August 2026, state that all bookings for travel products are subject to availability at the time of booking and that the platform does not guarantee a product will still be available when you book. ^{[2] [9]}

Tier credit also arrives late. Trip.com's loyalty terms count only completed bookings from certain product lines: flights after departure of the last flight segment, hotels after check-out is confirmed. So a price held today is not a locked price, and the reward attached to it may land well after you fly. Hold a booking only if the campaign's own published travel period covers your dates, its code and inventory windows fall on a day you can shop, and its discount survives the card or tier you already use. Otherwise, book on terms you can verify today. ^[10]
