The flight was excellent but the onboard WiFi wasn’t working.

The flight was full. The young man in the seat in front of me had reclined and I asked him to put the seat up just a bit because it was encroaching my space quite a lot. Turned out he couldn't because the mechanism was broken. The choice was all the way up or all the way down, no in-between.

The seat was hard as a rock. Business class seats were coach seats with no one in the middle. Service and food were excellent.

The crew was awesome. There was a school group of about 60 14 year-olds. The food is standard greek fare, Baklava was pre-packaged like it would normally be sold in a vending machine, and it was the highlight of the meal. Plane was in great shape, and seating was like a any A319 you would experience at a national-level carrier (i.e. not like Ryan Air). Like many European airports, they bused us to the plane, so the process of boarding groups is useless, and not well understood by infrequent travelers.

Departing from the Parikia apport on Paros was chaos. It is a 3rd world airport, and my home has more square footage. Olympic Air has several instances where there are less than two hours between flights leaving Paros. Further, there are two airlines at the airport, so airport resources are limited. With only one check in desk for each airline, the folks who are getting on the earlier flight are the only people who are able to check in. So, don't get there too early to check in. Also, the airport waiting area, after you go through security only holds about 1/2 of a plane's worth of people. So, the security line also has the same restrictions as the check in desks. Depending upon what time you get there, two queues will extend into the entry road. If your plan departs within the hour, go up to the front of the building and check to see which flight they are checking in or running through security.

Every one was attentive, the food was really very good . All and all was an excellent experience .

There was no enterteinment onboard. Food was good, and service too.

It was a short flight. It did leave about 15 minutes late but other than that everything went well!! There was no food service or entertainment so can’t comment on any of that.

Not good, the seat was broken and the middle seat table was not lowering, no option on the food, despite the business class wasn’t full. In the menu offered they had fish or chicken, no chicken available when was my turn (seating in raw 2!)

For a quick trip to athens they did a great job plane was spacious, and we boarded quickly.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Big queues on arrival at airport despite having already checked in and only needed to drop bags off. Flight delayed which impacted on connecting flight.

The update about flights and the terminal changes information was great.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre

The flight was excellent in World Travellor plus. Well worth the extra money. Boarding at Phoenix was the usual poorly organized event. Very stressful.

Although business class, the seating was really cramped. The food was so so.

Not only were the aircrafts spacious, but the crew was friendly and efficient. I was so gracious for the included meals on the longer flight (8+ hours).

Smooth trip no turbulence which is always a bonus for me lol! In cattle class so an element of being a bit squished (but not as bad as other shorter haul airlines) smaller plane than the one we flew out on and entertainment system wasn’t as modern but still definitely passed the time. Lovely crew x

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

Decrepit planes, poor business class layout designed to maximize revenue, no decent movie selection.
