Why not? A3 doesn't fly BEG-JMK.

Thru offer JMK via ATH

Paris is too close to Athens

Only domestic flights possible to/from Paros unfortunately (for now)

I think Paros airport runway can only handle propeller aircraft but I could be wrong.

Air Serbia has propeller aircraft. But I don't think Paros Airport has border and customs facilities.

Paros airport is being renovated and soon will handle international flights as well. Paros will boom I can see Austrian, BA, Lufthansa start first flights there.

Just a few comments - Paros is at best 3h ferry ride from Athens, and the ferry tickets are very expensive - e.g. 500+EUR for a return ferry trip for 2 adults, 2 minors and a car.
There are local flights from Athens and Thessaloniki which are also very much over-priced - indeed Paros airport needs an overhaul - but this is announced to be ready for next summer.

But all this is relevant in the first place, as Naoussa is developing to an extent that currently it is at "70-80%" of Mykonos old town's offering, the beaches are pretty much at the same level, and consequently that island is reaching the levels of Mykonos in terms of being loaded with high-paying tourists, Americans etc.

So for sure, should Air Serbia tap into this class of travelers, a bit outside our Balkan context - they should closely follow the developments at Paros as well.

P.S. Kudos for Mykonos flights introduction - it goes into almost exactly the same bucket...

Paros ferry tickets are not 500€ stop spending misinformation

Please be mindful of the fact that he wrote that it's €500 for two adults, children and a car. You should read more carefully the next time my friend.

Paros is way too far away for ATR.

@Anon 23:07 Yes they are - as I paid myself ~540 and returned just week ago; as written above - return for 2 adults+2 minors+1 car, by seajets - those vessels that take 3-3.5h one way. I purchased a month in advance, although there it doesn't matter when you purchase...
You can always check on e.g. Ferryhopper or Seajets directly.
It can be cheaper if you choose a slow ferry (this one was 3-3.5h one way), or if you fit into some special schemas for Greek citizens & families or if you are residing on the islands.
But yes - it is very expensive indeed.

Also, airline tickets from Athens & Thessaloniki to Paros are very expensive - when I was checking - more expensive than Belgrade-Tivat...

Anon 14:58 , you are talking like Aegean will lose a ton of money from this route ! The real money A3 is loosing is the suspension of Tel Aviv , a 1.000.000 + market !

"Failed spectacularly"? When did they fly from BEG to the Greek islands in order to fail in the first place?

They flew from RHO and HER to BEG.
Their RHO flights had similar times like the Sky Express ones so I guess they lost the agency contract.

Aegean doesn't seem to care about flights from other destinations except ATH and SKG. these are their main focus

Aegean has some 10-12 airbus 320/321neo inactive dut to engine checks and they have repeatedly said they are not very fond of wet-leasing airplanes. So, for the next 2-3 years, Aegean will focus in solidifying their place in Athens/Thessaloniki, building those hubs and trying some longer destinations (India and Africa) once they get their Airbus 321neoLR. So, don't expect them to be very active in the region for the next few years.

They have 42 weekly flights to Greece without charters.
