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 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.

it was hard to find the check in at the airport no signs food was average

Short flight. Was not told if there was a kosher option for the snack.

It is a wonderful airline. The cabin crews were friendly and the food as well as the service the were excellent.

Good but could be better for comfort and entertainment aspect

Overall it was not a pleasant experience, I was given the middle seat even though I asked for a change they didn’t honor

No WiFi working on either flight. No leg room at all, the seat in front of me left dents in my knees. If I put the tray down, it was so low it was propped up by my knees. (I’m only 182.9 cm) I’m usually cool on planes, but the planes were both hot during taxi and take-off.

Very bad.i will never book British flights for future

Moved me away from my family and refused to fix it.

I noticed the crew was so much nicer and friendlier. It would be nice if British Airways would serve soft drinks during the flight

Must have had an elderly tour on the trip. Plane boarded via tarmac and had both front and tail stairway access. We waited about ten minutes at the rear entrance while elderly folks entered the forward access and walked all the way back to last rows of the aircraft! We could not access the row until every one of them finally reached the final rows. There should have been an agent directing folks Forward and Aft based on seat row. It was comical.

The airport experience at check-in, just to drop a bag, was horrible. The were two agents working, two watching. We stood in line for just short of one hour. I asked the agent if this were normal and he said, "Well, yes. Just two computer terminals." No apologies. BA needs to fix this ASAP. Meanwhile, I've moved BA to the very bottom of my booking list.

Good shuttle to Europe. Face check boarding needs overhaul. 2 stations for 200 people and still with passport check. Why have both? Why is this now slower than 5 years ago?
