Understanding frequent flyer programs: miles, status tiers and alliance benefits

If you regularly fly to spotting destinations, you are asked at every check-in counter whether you have a frequent flyer number. Behind it is a system that looks confusing at first glance: miles, points, qualifying points, Silver, Gold, Senator, Emerald. This guide sorts out frequent flyer programs for you – how miles are earned, how a status tier comes about, what the three big alliances do with it and where it makes a real difference for spotters.

Frequent flyer program: the short answer

A frequent flyer program is the loyalty program of an airline or airline group. It keeps two separate accounts for you: on one you collect award miles, which you later exchange for flights, upgrades or merchandise rewards. On the other you collect status points, which you cannot spend but which determine which tier you reach. The tier in turn decides benefits such as lounge access, priority check-in or extra free baggage – and through an alliance, those benefits also apply at partner airlines.

At the big programs, basic-tier membership costs nothing. It gets interesting where the rules go into detail: what counts, how long it is valid and how much a mile is ultimately worth.

Where the mile comes from: a brief look back

The idea is older than many of today’s airlines. In 1979, Texas International Airlines introduced a program that tracked and rewarded miles flown. The breakthrough came in 1981 with AAdvantage from American Airlines. That same year, United, Delta and other airlines followed with programs of their own, and British Airways followed in 1982 with the Executive Club.

The name “mile” dates from that era, when credits were actually tied to the distance flown. In Europe, Miles & More launched in 1993 as a joint program around Lufthansa. Today, customers of SWISS, Austrian Airlines, Brussels Airlines, Eurowings and other airlines of the Lufthansa Group earn in this program. At Air France and KLM, the joint program is called Flying Blue.

Account one: award miles

Award miles are the program’s currency. You earn them on flights, but also with partners on the ground: with credit cards, in hotels, on rental cars, train trips or in online shopping. At many programs, a considerable share of the miles awarded now comes not from flights at all but from credit card partnerships.

Distance or price: how miles are calculated

For a long time the rule was: the farther you fly, the more you earn. This logic has largely disappeared at the big programs. The switch to revenue-based rules began in the US: Delta made the start in 2014 for status requirements, United followed in 2015, American in 2016. At Miles & More, mile credit on Lufthansa Group tickets has been based on the ticket price since March 12, 2018 – more precisely on fare and fuel surcharge, multiplied by a factor that rises with status.

Model	What counts	Who benefits	Typical for
Distance-based	distance flown, weighted by booking class	long-haul flights on cheap fares	older programs, partner flights at some programs
Revenue-based	ticket price excluding taxes and fees	expensive tickets, business and flex fares	Lufthansa Group, big US airlines
Segment-based	number of flights, regardless of length	many short flights	rather rare today, mainly smaller programs

For spotters, this means: a cheap weekend trip to a spotting destination earns only a few miles under the revenue-based model, even if the route is long. If you fly with an alliance partner, however, distance may count again for the same ticket – the programs’ partner tables are worth a look.

What a mile is worth

A mile has no fixed value. Its worth depends on what you redeem it for. Long-haul award flights in premium cabins usually yield significantly more per mile than merchandise rewards from the shop. On top of that, many award flights come with taxes, fees and surcharges that you pay in cash. And programs change their award charts. If prices rise, your balance loses value without you having done anything. The industry calls this devaluation.

When miles expire

Here too, programs differ. At Miles & More, award miles generally expire after 36 months. Customers with status and holders of certain program credit cards are exempt. Other programs tie validity to activity: as long as you regularly earn or redeem, the account stays alive. Note down the expiration date if you only fly occasionally.

Account two: status and status tiers

Status is what visibly sets you apart from other passengers at the airport. Status points go by different names depending on the program – qualifying points, tier points, XP – but work similarly everywhere: within a fixed period, usually a calendar or membership year, you have to reach a threshold. After that the status holds for a certain time and then has to be earned again by flying.

Example: Miles & More

Since 2024, Miles & More has worked with Points, Qualifying Points and HON Circle Points instead of the former status miles and HON Circle miles. Above regular membership there are three tiers:

• Frequent Traveller: according to the program description, 650 points within one calendar year, at least 325 of them qualifying points. The qualifying points ensure that part of the performance is earned on flights.
• Senator: the second-highest tier with a significantly higher threshold. Senators use Lufthansa Senator Lounges and Star Alliance Gold lounges, among others, and receive extra free baggage.
• HON Circle Member: the top tier, reached with 6,000 HON Circle Points in a calendar year. These are only available for flights in business and first class.

Other programs set their own accents. British Airways renamed the Executive Club to British Airways Club in April 2025 and switched Tier Points to spend-based awarding, while Flying Blue works with Experience Points (XP) and the tiers Explorer, Silver, Gold and Platinum. The exact thresholds change from time to time – the official program page is always what counts.

Alliances: your status at the partners

An alliance is not a frequent flyer program of its own. You always earn with one member – but the alliance makes sure you can earn and redeem miles at all members and that your status is recognized there. To do this, it translates the tiers of the individual programs into a few alliance-wide tiers.

Alliance	Founded	Lower tier(s)	Upper tier	Example programs
Star Alliance	1997	Silver	Gold	Miles & More, United MileagePlus
oneworld	1999	Ruby, Sapphire	Emerald	British Airways Club, AAdvantage
SkyTeam	2000	Elite	Elite Plus	Flying Blue, Delta SkyMiles

Star Alliance is considered the first global airline alliance. It was founded in 1997 by Air Canada, Lufthansa, SAS, Thai Airways and United. oneworld started in 1999 with American Airlines, British Airways, Canadian Airlines, Cathay Pacific and Qantas. SkyTeam followed in 2000 with Delta, Aeroméxico, Air France and Korean Air.

What the tiers bring

In Star Alliance, Silver mainly gets you preferential treatment with reservations and waitlists. Gold adds priority check-in, priority baggage handling, extra free baggage and access to the members’ lounges. At Miles & More, Frequent Traveller corresponds to Silver status, Senator and HON Circle to Gold.

At oneworld and SkyTeam the logic is similar: the lower tiers bring priority on booking and waitlists, and partner lounges generally open from oneworld Sapphire or with SkyTeam Elite Plus. At SkyTeam you recognize the preferential treatment by the SkyPriority signs at check-in, gate and baggage claim. Details such as guest rules are set by each program itself.

Incidentally, alliances are interesting for the camera too. Many members carry an alliance livery on selected aircraft – which patterns exist is shown in the article Star Alliance, oneworld and SkyTeam liveries. And how partners market each other’s flights is explained in the guides to codeshare flights and transatlantic joint ventures.

What a frequent flyer program brings spotters

Hardly anyone flies their way to lounge status just for the hobby. But if you travel a lot anyway, you can use the benefits specifically for spotting.

• Lounges with apron views: At big hubs, many lounges sit right at the glass front facing the apron. During a layover in Frankfurt or Munich, you often see long-haul jets up close there. Reflections in the glass are the main problem – holding a lens hood right against the glass helps.
• More baggage for gear: Extra free baggage and higher weight limits make it easier to bring a tripod, ladder or a second lens.
• Award flights to spotting destinations: Miles are well suited to routes that would be expensive in cash. Especially for trips to faraway destinations, an award flight can ease the budget; tips for the rest of the budget are in the guide Planning spotting trips on a budget.
• Better seat selection: Many programs give status customers free or earlier seat reservations. That secures you the window seat ahead of the wing – how to pick the right one is explained in Choosing the best window seat for photos.
• Rebooking during disruptions: Status customers rank higher on waitlists. That helps when a spotting day at the destination airport is about to fall through because of a delay.

Choosing the right program

The most important rule: earn where you actually fly. Spreading miles across five accounts ends up getting you a reward nowhere. If you mostly travel from a Lufthansa Group hub, Miles & More is the obvious choice. If you often fly via Amsterdam or Paris, Flying Blue is the logical choice. For trips with British Airways or Iberia, a program of the International Airlines Group is a good fit.

Also important: you do not have to earn in the program of the airline you fly with. Within an alliance, you can, for example, have a SWISS flight credited to another Star Alliance program. That is worthwhile if a partner program gives more points for your fare or you are already close to a status threshold there.

And the low-cost carriers?

Classic low-cost airlines like Ryanair do not rely on mileage-based loyalty programs with lounges and status tiers. Their business model lives on low base fares and paid extras – more in the guide How low-cost carriers work. It looks different for group subsidiaries: Eurowings flights can be credited to Miles & More. How airline groups divide up their brands is shown in the article Multi-brand strategies.

What to watch out for

• Name exactly as on your passport. If the name in your frequent flyer account differs from the booking, automatic crediting fails.
• Keep boarding passes and ticket numbers. You can usually only claim missing miles within a deadline, and you need the documents for that.
• Not every fare earns. Some saver or basic fares bring few or no status points. Check the conditions before booking.
• Do the credit card math soberly. Co-branded cards bring miles but usually cost an annual fee. They only pay off if you actually redeem the miles.
• A lounge is not just a lounge. Which lounge your status opens depends on tier, alliance, departure terminal and sometimes the travel class.
• Be discreet with apron photos from the lounge. The operator’s house rules apply in lounges. Photograph aircraft, not other guests, and ask if in doubt.

Conclusion

Frequent flyer programs seem complicated but follow a clear logic: award miles are the currency, status points the ticket to tiers and benefits, and the alliances translate those tiers for all partners. Because more and more programs credit by ticket price rather than distance, cheap spotting trips earn few miles. But if you travel with an airline family anyway, you benefit from award flights, more baggage for your gear and lounges that at big hubs sometimes offer the best apron view of the day.
