Seat spacing good ( I am tall), very friendly and competent cabin crew. Good updates from flight deck. Excellent boarding and disembarcation

Generally excellent but a couple of areas could be improved. After boarding we were delayed a full 20 mins whilst various ground crew, flight crew, captain faffed around counting and recounting passengers. Said discrepancy between computer and manual. All OK in the end. So why o why did it take 20 mins to find all OK? No sense of urgency shown Secondly the seat base is just not supportive/resilienfor a 4½ hour journey - backside really aching by journey end.

Waiting for 2 people to come through security that delayed the flight. Everyone else made it on time, should have left without them. Flight was cold.

The staff are just so friendly travelling alone was a bit scary but they made me feel comfortable and nothing was to much bother I loved how one of the girls was talking to the old ladies she really took time thank you jet2 shame I can’t get home with u guys 🥲

Crew was nice. Plane was crowded, Seats wouldn’t lean back. No free treats or drinks (not even water).

The flight was over an hour late taking off. Air traffic control on the outward flight caused the delay. Horrendous passport queue at Malaga. Families with children must dread it. Another Brexit negative

On time flight. Reasonable comfortable but a bit cramped. Excellent jet 2 staff as usual.

This is my second flight with jet 2. Both been great - lovely helpful staff. Will fly with you again

Felt very cramped, seat quality poor and temp way too warm with little ventilation. Persistent ramming of duty free ‘bargains’ donut throats. Food & drink service glacially slow.

A good flight with friendly crew and check-in but disembarking was chaotic and badly managed

Aegan Airlines compensates for its outdated business-class seats with excellent food and onboard crew service. Launge was also excellent.

For a business class, it barely met the standards of a basic economy on most carriers. The seat would barely recline; no pillow or blanket unless you ask a crew member; no leg rest (at least in the 1st row). The crew was friendly and attentive, except for one male crew member who was very inconsiderate toward many business passengers who were already sleeping or trying to sleep, slamming the doors of the kitchen compartments. He did so twice till another passenger complained to him. Overall, business class is an economy experience except for the food.

Seats that recline. Ice for soft drinks. No charge for did drinks. Wifi.

Internet not working during the flight - what a big miss!

Aegean Airlines was great! Great spirit, very helpful and efficient. Overall Aegean Airlines was a great experience.

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.

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 .

Enough seat availability for us to move a little and so sit together - but the flight was half an hour late

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't eat any food so can't comment on that. The prices on the plane are extortionate (as are all prices on planes). Everything else was seemless and a great experience

I need assistance and I could not fault it at all. I suffer anxiety and I was always put at ease by assistance staff, and the banter was good. On board the staff was so very nice and kind and showed empathy. Thank you to them. It was my first time travelling since I lost my husband and was so grateful to them.

Great flight just took some time to board even when lining up early for the flight, even taking off took longer then expected.

Take off was great but landing is always with a bump.

Flight was delayed by 1 hour 45 minutes. Aircraft was cramped, dirty and uncomfortable. Boarding staff more interested in charging you for oversize baggage than getting you on board. Overall not a pleasant experience.

A delay of almost 3 hours. It was evident that the staff wanted us to board urgently, to the point of rudeness, to avoid paying compensation

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

On time arrival but the aircraft had seen better days and needed a deep clean.

Whole way through - far more professional and slick than I expected

Good news was that Bag Check was open two and a half hours before the flight, which is essential with the chaotic immigration process. Flight was okay, but sitting at the back of the aircraft, 3 overhead bins on both sides were filled with crew bags and other misc items, so we couldn't put our cabin bags anywhere near us. To add insult, twice the crew managed to drop items that they were taking out of the overhead bins onto my wife's head, who was sitting in an aisle seat.

It was good; the only down side is that once you get to the airport everything is self service, there is no one assisting. I felt like I was working while I was on vacation during the check in process and dropping off the luggage. Really uncertain on what the airlines use payroll nowadays.

It was good except they could offer free water and tea/coffe

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Boarding and disembarking were smooth. Not offering free water was cheap ... I've never encountered that before on a flight.

Boarding could be better. To get through your gate but to be stood in a corridor for 20 minutes is not great.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Cheap Flight Fares would not provide booking info. I canceled the reservation and we arbitrated with American Express. They provided erroneous info to Amex and it was determined that C.F.F. deserved the price of the ticket. Worse experience I've ever had.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Waiting area not big enough for all the passengers, no airport lounge.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

I liked that we got there safely. I disliked long delays, gate and ticket agents incompetence and apathy and having my luggage lost. Five days later I've yet to get anything more than a generic apology from British Air. Luggage yet to be located, much less returned.
