Every loyalty programme runs a clock that determines whether you keep, earn, or lose elite status, and the clocks do not all reset at the same moment. Knowing when each major programme’s qualification year ends is the difference between a well-timed trip closing a gap and the same trip landing in the wrong window entirely.
The five types of qualification clock
Major airline and hotel loyalty programmes group into five distinct clock types. Most US carriers and large hotel chains share the simplest model: a fixed calendar year that resets on 1 January. But American AAdvantage (a March-to-February year), British Airways, Air France-KLM, and several Asia-Pacific and European programmes each run a different structure that catches members off guard when they plan using calendar-year instincts.
Calendar year (resets 1 January)
The most widely used structure. Qualifying activity from 1 January through 31 December counts toward status, and the counter starts from zero on New Year’s Day. This is the model used by United MileagePlus (Premier Qualifying Points), Delta SkyMiles (Medallion Qualification Dollars), and Lufthansa Miles & More (Points and Qualifying Points on a calendar year per the programme’s current terms). American AAdvantage is the notable exception among large US carriers: it runs a March-to-February year instead, covered in its own section below.
On the hotel side, the same calendar-year structure applies to Marriott Bonvoy, Hilton Honors, World of Hyatt, IHG One Rewards and Accor ALL. For these programmes, a qualifying night on 31 December belongs to this year’s counter; the same night on 1 January begins a fresh count toward next year’s tier.
Accor ALL belongs with the calendar-year programmes rather than the personal-year ones: Accor’s help centre sets status by the Status points and nights earned from 1 January to 31 December, re-evaluates it on 1 January and carries nothing over, counting each stay in the year it ends. Per Accor’s status page, Silver needs 10 nights or 2,000 Status points, Gold 30 nights or 7,000, Platinum 60 nights or 14,000, and Diamond 26,000 Status points, with no nights route.
The practical consequence is that the final quarter of the year is decision time. If you are within striking distance of a threshold in October, November, or December, you have a genuine window to act. If you are not, there is no carryover: the qualifying total resets regardless of how close you came.
March-to-February year (resets 1 March)
American AAdvantage is the major exception to the calendar-year norm among US carriers. Per American’s AAdvantage member statuses page, the qualification year runs from 1 March to the end of February, and the Loyalty Points counter resets on 1 March. Status earned in a qualification year is then valid through 31 March of the following year, the familiar 14-month AAdvantage status runway. The planning consequence is that AAdvantage members run their year-end push in January and February, not in December. We track the exact thresholds in the dedicated tier guides linked below.
April-to-March year (resets 1 April)
The British Airways Club (the programme formerly known as Executive Club) uses a qualification year that runs from 1 April through 31 March. British Airways’ own tier pages set the current thresholds at 3,500 Tier Points for Bronze, 7,500 for Silver, 20,000 for Gold, and 65,000 for Gold Guest List, all earned within that April-to-March window.
For members who also chase a calendar-year US programme, the misalignment is easy to underestimate. A January transatlantic trip earns Tier Points in the current British Airways year (which does not close until 31 March) while simultaneously earning Loyalty Points in the next US programme year. The same flight lives in two different qualification windows at once. Tracking both against their respective deadlines rather than one shared calendar date is the only way to stay ahead of it.
Activity expiry in the British Airways Club runs roughly 36 months on Avios from the date of last earning activity, per the programme’s current terms, though the qualification Tier Points clock resets each April regardless of whether Avios expire.
Personal qualification period (restarts on every upgrade)
Air France-KLM Flying Blue takes a structurally different approach, and it is often mislabelled as a rolling window. Rather than a shared start and end date, Flying Blue’s Status & XP page gives each member a personal qualification period of up to 12 months, starting when they first earn Miles or XP. Reaching the next level upgrades the member at once, deducts that level’s XP from the counter and starts a new period; at the end of a period, a member with enough XP keeps the level and one without moves down one level. Nothing ages out month by month, and there is no shared year end. Silver requires 100 XP, Gold 180 and Platinum 300, each counted from the level below, and Ultimate requires 900 UXP, a separate counter earned on flights marketed by Air France or KLM.
A personal period demands a different planning posture: the question is not “what do I need before 31 December?” but “when does my own period end, and how far is my counter from the threshold?”
Personal membership year (tied to enrolment or to your last tier change)
Several programmes run the qualification period on a clock personal to each member, so the year end may fall in any month of the calendar and differs from every other member. What starts that clock varies: Qantas counts from when you joined, while KrisFlyer and Emirates start a new year whenever you move up a tier. Three significant programmes use this structure:
Singapore KrisFlyer: per KrisFlyer’s Elite qualification page, Elite Silver needs 25,000 Elite miles and Elite Gold 50,000, earned within 12 consecutive months. Membership then lasts 12 months from the upgrade, and renewal needs the same Elite miles again within that membership year, since the counter resets to zero when it ends. PPS Club and Solitaire PPS Club are a separate ladder built on PPS Value. KrisFlyer miles held by Basic and Elite members expire three years after the month they were earned, however active the account is.
Qantas Frequent Flyer: per Qantas’ status tiers page, every member has a Membership Year based on when they joined, and Status Credits reset to zero at the start of each one. Bronze is the entry tier; Silver requires 300 Status Credits, Gold 700, Platinum 1,400 and Platinum One 3,600 within the Membership Year. Silver to Platinum also need four flights with a Qantas or Jetstar flight number, and Platinum One needs at least 2,700 of its Status Credits on flights with a Qantas (QF) flight number. A tier reached part-way through a Membership Year lasts for the rest of it and the whole of the next.
Emirates Skywards: per Emirates Skywards’ membership tiers page, you move up as soon as the tier miles earned in the last 12 months reach the next threshold. The tier then runs from the day you qualify to the end of the same calendar month a year later, and keeping it takes the same tier miles again within that period, so the review date follows your last upgrade or renewal rather than a shared calendar date.
Activity and points expiry: a separate clock
Qualification-year resets and points expiry windows are two distinct clocks. Status requalification determines whether you hold a tier; expiry determines whether the miles or points you have earned retain any value. AAdvantage miles carry a 24-month inactivity window per American’s programme FAQs; IHG One Rewards and Accor ALL use 12-month windows, and British Airways runs a window of roughly 36 months tied to activity. KrisFlyer works differently: its miles expire three years after the month they were earned, however active you are. For a programme-by-programme breakdown of what each currency is and how qualifying units differ from redeemable points, see the companion piece on status currencies explained.
Timing strategy by clock type
Knowing the clock type immediately suggests the right planning posture for each programme.
Calendar-year programmes: the Q4 calculation
From mid-October onward, every member of a calendar-year programme should run a straightforward calculation: current qualifying total versus threshold, against the trips already booked before 31 December. If the gap is closeable with a booked flight or a stay already on the calendar, there may be nothing to do. If the gap requires deliberate additional activity, the Q4 window is the last practical point to act.
April-to-March programmes: the January check-in
For British Airways Club members, the equivalent of the Q4 calculation falls in January and February. With the qualification year closing on 31 March, any trip taken in the first quarter of the calendar year carries outsized importance for the BA programme. A long-haul January flight that yields Tier Points may be the difference between retaining Gold and dropping to Silver; the same trip credited to a calendar-year airline programme counts toward a year-end target still nine months away.
Personal-period programmes: the Flying Blue view
For Flying Blue, the planning question is different again. Rather than a shared deadline, the relevant date is the end of your own qualification period, which moves forward every time you reach a new level. Nothing from 12 months ago drops out along the way: what counts is whether the counter holds your level’s threshold when the period closes. A burst of XP-earning activity that reaches the next level upgrades you immediately rather than waiting for an annual reset, and starts a fresh period at the new level.
Personal membership year programmes: record the date
For KrisFlyer, Qantas and Emirates Skywards, the single most important planning step is recording the date your current membership year ends and treating it as a hard deadline in the same way a calendar-year member treats 31 December. For KrisFlyer and Emirates, update it every time you move up a tier, because an upgrade starts a new year. Because the date is personal, there is no shared community moment to serve as a reminder. You may have earned your tier in February four years ago and have little reason to remember it unless you have written it down.
Miles Mosaic, for example, is built so a cross-programme tracker can record each programme’s renewal date next to its qualifying total, giving you a single view that surfaces when your personal year closes regardless of the programme type. It never asks for a loyalty password; the dates and balances are entered or uploaded by you. For membership-year programmes in particular, that kind of explicit record makes the difference between acting in time and discovering the window closed last month.

Elite tier thresholds by programme
The qualification clock tells you when to act; the tier thresholds tell you how much. This is the hub for the two programmes whose tier ladders we track in depth, with a link to each dedicated tracker. Verify the current numbers with each programme before booking, as thresholds can change.
American AAdvantage (Loyalty Points, March-to-February year)
The 2026 thresholds are frozen for a third straight year. The headline mapping change is that American upgraded Platinum Pro from oneworld Sapphire to oneworld Emerald, so both Platinum Pro and Executive Platinum now carry the alliance's top tier. The dedicated Platinum vs Platinum Pro comparison sets out exactly what the extra 50,000 Loyalty Points buy.
Air Canada Aeroplan (Star Alliance, calendar year)
Aeroplan moved to a single Status Qualifying Credits (SQC) metric from 2026, replacing the older Status Qualifying Miles, Segments, and Dollars. Confirm the live SQC thresholds on Air Canada’s Aeroplan status qualification page; the five tiers and where each sits in Star Alliance are tracked in the dedicated guides below.
Running this across five clock types sounds complicated, but it reduces to three habits.
Record every reset date explicitly. For calendar-year programmes, that is 31 December, shared universally. For BA it is 31 March. For personal-year programmes, look up and write down your specific anniversary date. For Flying Blue, record the end of your current qualification period and update it each time you move up a level, because an upgrade starts a new period.
Run a status check six weeks before each deadline. Six weeks is enough time to make a deliberate booking if you find a closeable gap. Two weeks is often too late for the calendar-year programmes because December travel books out quickly. For the April-to-March BA year, mid-February is the equivalent window. For Flying Blue, “six weeks before” means six weeks before your own qualification period ends.
Use booked trips, not hoped-for travel. A projection built on flights you might take is not a projection; it is wishful thinking. A useful status forecast counts only confirmed bookings in the correct cabin class on fare types that earn qualifying currency. For a practical walk-through of applying this across multiple programmes, see how to track elite status across every programme.
Soft landings and status rollover
Several programmes offer protection against a single bad year through status extension or rollover mechanics. Calendar-year programmes that offer a form of rollover typically extend the current tier or reduce the requalification threshold if you meet a partial target by year end. Exact conditions vary, so the right question is not only “can I requalify?” but “which programmes offer a soft landing if I fall short, and which will simply drop me?”. We cover the mechanics in detail in the guide to soft landings and status rollover.
The bottom line
Qualification clocks are not an administrative detail. They are the architecture that determines whether a trip earns you the status you are planning around. Calendar-year programmes make Q4 the critical window. The British Airways Club makes January and February equally important for a different reason entirely. Flying Blue makes it personal rather than seasonal. And personal membership year programmes make your specific anniversary date the single most important date to record.
None of this is particularly complicated, but all of it requires knowing which clock you are looking at. If you hold status across more than two or three programmes, keeping that picture in one place is the only way to act on the right deadline at the right time. You can track all your programmes in Miles Mosaic, or create a free account to record your qualifying totals and renewal dates alongside each other.

When does American AAdvantage’s qualification year reset?
American AAdvantage does not use a calendar year. Its qualification year runs from 1 March to the end of February, and the Loyalty Points counter resets on 1 March each year. Loyalty Points earned between 1 March and the end of the following February count toward that status year, so the AAdvantage deadline is late February, not 31 December.
How does the British Airways Club qualification year work?
The British Airways Club runs an April-to-March qualification year. Tier Points earned between 1 April and 31 March determine whether you earn or retain Bronze, Silver, Gold, or Gold Guest List status for the following year.
Does Air France-KLM Flying Blue use a rolling 12-month qualification window?
No, although it is often described that way. A rolling window would look back over the most recent 12 months every day. Flying Blue instead gives each member a personal qualification period of up to 12 months, which starts when they first earn Miles or XP and starts again whenever they move up a level. At the end of the period, a member with enough XP keeps the level and one without moves down one level, and a new period begins.
What is a personal membership year in loyalty programmes?
It is a qualification year personal to each member rather than a shared calendar date, but programmes start the clock differently. Qantas Frequent Flyer bases the Membership Year on when you joined and resets Status Credits at its start. KrisFlyer Elite and Emirates Skywards start it when you move up a tier: KrisFlyer Elite status lasts 12 months from the upgrade, and an Emirates tier runs to the end of the same calendar month a year after you qualify. Accor ALL is not one of them, because its status is set by the Status points or nights earned between 1 January and 31 December.
Why does it matter which type of qualification clock a programme uses?
The clock type determines when you need to act. Calendar-year programmes reward a Q4 push, so a well-timed late-year trip can close a gap before the 31 December deadline. Flying Blue's personal qualification period restarts every time you move up a level, so the deadline moves with your progress. And personal membership years mean your deadline may fall in any month, unrelated to the calendar, so missing it by a few weeks is easy if you are not tracking the date explicitly.
