To me it's really surprising that it's taking Aegean 2+ years to decide what changes they want to make. Makes you wonder what is the decision making process of the company.

Allow me two comments: 1) From Aug 4, 2024 (OP) till June 7, 2025 is hardly "2+ years" but just two days more than 10 months! 2) If you read the page linked to by the OP, it is such a "bla-bla" kind of a PR piece, that one would hardly call that part of a "decision making process of the company".

Given the Greek market profile this would actually be disastrous.

Beyond the fact that Greek income levels wouldn't be high enough to do so, one of A3's main challenges is to keep the planes as full as possible in the winter seasons where demand is much weaker.
They don't need to rely on spend itself. The planes keep itself full in the summer months; and they are probably happier letting each summer tourist pay 400 quid for a single to Greece and not providing the relevant frequent flyer benefits than otherwise.

And after all, it remains a rumour. I've been a member of M&B for about twenty years now and there's only been one significant change but not a year goes by but there are rumours.

How about waiting for an announcement?

Off the top of my head, I can think of two major changes in the last ~10+ years. The 2014(?) one when legacy Golds got the 23/24 November tier retention dates. And the 2023 one when they dramatically increased the non-A3 requirements from 24k/48k to 70k.

Well, it wouldn't be FT without rumors, conjecture, speculation, and discussion, would it?

I guess for those of us who actually fly with A3, the 2023 change was a non-event because provided you had your four sectors it was a non-event :-)

To give another example: When A3 started charging for the free up-front seats for Goldies (�now with a 50% discount�). When was the last time A3 actually enhanced something for Golds?
Yes, A3 sets high standards and yes I am happy with them. It doesn't mean I'm looking forward to deteriorated services or I/we can't critizise them.

Just because this thread was started 10 months ago does not automatically mean that Aegean has been deliberating for 2+ years on making changes to tiers/requalification....

Now there's a thought! Seasonality of mileage earning.

Perhaps A3 could be the first airline (that I know of) to offer different (tier) mileage earning depending on the time of year....

Some airlines have this for redemption (charging [slightly] more during peak periods); it might be an idea to offer increased mileage earning for off-peak periods on their own (A3/OA) flights...or at least on a subset of their flights

I know some are completely against the change, but I consider this a huge step forward:

Upgrading to Business Class just got easier - FlyerTalk Forums

That would suit me fine because I ONLY fly in winter (I work 7 days a week in the tourist industry here in Greece). BUT... it wouldn't be "increased mileage earning in off-peak periods" of course, it would be 'normal' earning in off-peak periods and REDUCED earning in peak!

Imo the fact you can not upgrade bookings where you're not listed as passenger is a serious downgrade. I mainly used the vouchers to upgrade my parents.

The dedicated bus on arrival is nice indeed, in part because it can help with tight connections.
I think one reason they don't consistently do it on departures is because C passengers may well arrive to the gate at anytime. They could still just do a bus at the beginning for the C passengers accumulated as boarding begins, but I can understand why they don't.

Is it possible they could also segment based on country of residence (or rather address of M&B profile)? Some carriers offer a lower set of requirements for certain domiciles, Some even offer an entirely separate program to sidestep optical issues. I don't want to give them any ideas, but if A3 were to mimic these others carriers it would allow them to raise the requirements in M&B for say, non-Greek residents, while allowing Greek residents to retain their privileges. In a way, the optional segment-requirement is somewhat of a "residency-carve-out" but they could segment further.

I'm not sure this will be seen by everyone as an "enhancement", but it certainly has something to do with both your question and statement above:
When A3 changed the earnings calculator/table/chart/whatever for its own flights, it actually only decreased earnings on light and the very cheapest flex fares, while everything else saw an increase in miles earned, especially business class (which for my favourite route went from a "flat" 2000 to over 3100 miles, or over 55% more!). If it wasn't for that I (and probably many others) wouldn't have made it to gold. This also indirectly means that the "standards" for reaching and maintaining gold were effectively lowered (though the ones always flying in economy "light" can argue about the opposite).

Anyway, I am now reading quite a few speculations about this matter around here.
I do acknowledge the fact, that Aegean usually implements changes on short notice (which can justify the impatience I observe in some comments), but since we actually have zero clues with regards to specific changes I don't think there's any point in speculating any further than we already have and that we should just wait and see.

I actually wouldn't mind! Greece is way better appreciated in the quieter seasons. It baffled me, a tropical islander (Singaporean), when living in the UK, that everyone was milling to go to Southern European in its hottest months. The UK was much nicer during those very same few months, and Greece unbearably warm. Never understood why people didn't go to Greece in the colder months when it was just miserable in Northern Europe.

Correct me if I'm wrong, but don't usually residency carveouts request for lower mileages from non-domiciled residents? BA used to have lower requirements for European residents, for example. I don't see why A3 would be especially kinder to Greek residents when they are pretty much the captive market (Greeks have to fly even in the lower seasons), they just need to ensure that they give enough freebies for them to choose A3/OA over Sky Express at any given moment. I could see an alternative avenue to earning status via just segments alone, though, to placate this market if they had to raise the amount of miles for A3 *S and *G.
