Lovely experience with Aegean. The crew felt with some extremely rude customers with professionalism and poise. The flight went off without a hitch and even landed early!

Lovely experience with Aegean. The crew felt with some extremely rude customers with professionalism and poise. The flight went off without a hitch and even landed early!

When a flight has a delay of about an hour it is customary to announce the passengers

Nice business class service for shot flight. Especially when the free WiFi works

I liked bumping up to Business for less than full price. Also the option to choose your own meal online. In retrospect I would have gone with the standard meal option, but c'st la vie. Overall pretty standard flight, got good views of Greece as the sun rose. That's about it.

It was a short flight (2hours) so the tiny, tiny seats were somewhat tolerable. People with long legs had their knees up to the chair in front of them, quite uncomfortable. I was pleasantly surprised they served a small meal which was quite good. Staff were all great.

Boarding in BCN was really poorly managed. No communication from airline staff and no signs as to what groups line up where. It was just guessing. There were delays that were also not communicated so everybody was standing in line for almost an hour.

they were good. they coordinated pick up of luaggage at final destination. The had text updates on phone with gate/dep.time etc.

I love flying with Aegean. Crew is always polite and empathetic. Boardi

The flight was good. There was free WiFi which was fantastic. The crew was a bit rude and short tempered. The landing was super smooth

Flight was late leaving which made connecting in Athen very hard. Baggage took an hour to come out. Come on… for such a small plane. Need to step up your game Aegean!

Apart from an email about re configuring passenger seating less than 24hrs before flying it was all good.

There were a lot (4 I think) of EasyJet flights leaving Agadir, we arrived two and a half ours before our flight. Very slow to get through the booking in, passport control and security!! We had booked in on line but had to Queue with others who had not to drop our bags off!,

We boarded and then sat on the tarmac for an hour….probably not E Jets fault. But the gentleman that checked us in and took our luggage was exceptionally friendly and calming for early morning/ confused passengers. As always, it’s the people that make or break an experience, right?

I was hesitant to book with a low cost airline due to previous experience but Easy Jet surpassed my expectations. I would definitely book a flight with them again! Seemless booking, upfront about baggage fees, professional, and helpful staff.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Usual issues with flight delay. Perennial problem of travel by plane.

i didnt go this was a hacker booked this flight on my debit card !

Delayed almost 2 hours sitting on plane. No updates at all from flight deck and virtually no updates from cabin crew

Long delay resulted in my being unable to catch a train home and resulted in an additional £76 cost for an Uber

I was charged at the gate for bags I had already paid for. There was no other option. I am trying diligently thought easyJet website but making no progress HELP!

My flight from Krakow was delayed over 2hrs. Since i had connecting flight i was worrying that I will not be able to catch flight from Frankfurt to New York. NO information NO help, no one was able to help and let us know if passengers will be able to catch the next flight. Had to run through entire airport and (2) passports control hoping that maybe still be able to board the plane. When i got to the gate i was informed that plane was waiting for passengers that came from delayed planes. Flight departure an hr late. So i run throu airport almost having a heart attach just to fin out that they knew and they were waiting for us. I was just 5 minutes later after "official" boarding ended and they were still letting passengers in, and flight departure an hr. later.

The real bathroom smelled horrible and it smelled in the real of the plane..

No Wi-Fi or food unless you pay an expensive fee.

Did not fly HOU to SAT as flight was cancelled.

Not good. They charged an additional $70 to check a bag we had already paid for on line with Lufstansa

The seats were extremely uncomfortable. I spent €25 on internet and never gained access to it. A flight attendant told me she would file a complaint/report on my behalf but it put me in a very difficult situation.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Flight took off late. Flew business class. Lunch choice was chicken or vegetarian gruel. Chicken was gone by the time the flight attendant got to me. Got the salad, rolls, and desert. Skipped the vegetarian gruel. Almost broke a tooth on the roll. Suspect at it was least three days old...bird food. Wheelchair service (for spouse) at ATH was outstanding. Wheelchair service at FRA was mediocre as usual/expected.

Leg room was ok 1 flight attendant threw headphones at us. Very rude Overbooked flight thank goodness I got a seat Bathrooms smelled and urine all over the floor

No assistance as requested. Very late take off. Very hard landing And again , no assistance after landing
