Flying from Athens to Mykonos

I would like to fly from Athens airport to Mykanos.

The cheapest flight is Volotea. Is this airline reliable or should I just take a ferry. The cost to fly with Volotea is almost the same cost as taking a ferry.

Volotea is a budget airline but it is reliable indeed.
You shouldn’t have any issues at all and the flight is very short bout 30 mins , so nothing to worry too much about to be honest…

Have you ever used the airline yourself

Have you ever used the volvateo airline yourself. Do they get you on carry on and baggage charges

Yes ideed.
You are going to have extra charges for baggage but it’s always better to check the airline company as each one has a different policy on that in Europe.
