Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

You should not have to pay for WiFi in business class

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

The flights were in time and the bags arrived. well done

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Overall good. I was surprised how easy it was to get from plain to plain in such a short time. Food choices were not so great and quite expensive. Entertainment was ok. Flights were smooth.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

Bad. Flights were late, by hours. No clear information was provided even until the delayed boarding time.

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

take snacks and food. purchase options in flight are not great

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

There was no flight. I booked a flight from Toronto to Bordeaux with a stopover in Dublin. I arrived in Dublin and the flight number I had didn't exist and the flight going to Bordeaux I wasn't on. I had to book a new flight with a different airline for later in the day and pay out of pocket.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Really lovely trip and flight. The flight staff were so accommodating and warm throughout!

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

The seats in row 31 are terrible and small and uncomfortable. Don't ever sit there. The window seat is so close to the curve of the plane is so annoying. I paid extra for this seat and I hated all 10 hours in it.

Food was terrible , crew were excellent , IFE was dire . Overall comfortable seat and cabin. Nothing special .

If my tv wasn’t broken and I wasn’t in a seat that didn’t allow for sleeping

Delayed flight due to lack of crew caused me to miss my connection

Please make sure the number of seats matches the number of overhead bins and passengers don't carry on more than one bag.

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

Boarding was chaotic. Glad we were group 5 and still had cabin storage available when we boarded. I was expecting crew would get our carryons at the gate since theyclaimed it was a full flight.

Boarding crew is unfriendly as i was asked to handover carryon luggage too upto final destination Bangalore I was not prepared for that and i had to travel without my diabetic and hypertension medicines

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.
