We travel annually to Naxos. Sometimes we take the ferry but lately we have chosen to fly. There are 4 of us travelling. We have managed to book 3 seats on the flight to Athens for our return. This year there appears to be only one flight per day in September. I am trying to find out if there may be more seats released later or another flight added. I don't mind taking the ferry but would prefer to travel with my family. Any suggestions?
