Bring snacks. Double check with the airline that everything is in order. Never go through large airports like Heathrow with any layover that’s less than 3 hours. Small airports are preferred for layover like Dublin or Brussels.

Fine, the process or boarding was a bit slow but the flight itself was quick and smooth. Not over booked and pleasant overall

More check-in counters or faster processing. I arrived early but got to the gate just in time to board the flight, I didn't even have time to use the bathroom. The plane was really dirty, encrusted dirt is everywhere and the plane smelled bad when I entered.

I couldnot board the flight since my previous flight from Lisbon to Madrid arrived too late.

The flight was on the time and everything was very smoothi

Asientos y tener espacio para maleta de mano y no tener que facturar

The first flight was delayed and left us with a tight connection from Dublin to LAX. We would have made it and only had carry on luggage, however we were turned away and not allowed to go to the gate because they gave our seats away!

Boarding was messy and the flight was delayed an hour

Flight was delayed no information given really . No food whatsoever on the plane . I think you should be able to put that on the app so people have a chance to buy food bring it with them . They said plane was very busy on way over but there should be enough for both flights as we pay full price for the service. No information or very slow on the app about the delays . Staff were lovely it’s not their fault so company not fare to passengers or staff .

Everything was great. I liked that one of the crew noticed my son's sunflower lanyard and asked them to let them know if we needed anything. That was lovely.

The check in process at the front desk felt slow and it was frustrating that we could not check in online. Everything about the actual flight was great, including very kind flight attendants and a nice larger bathroom. Only thing is that it was very cold in the plane!

The folks and flights were fantastic. I unfortunately wasn’t able to order a meal that I could eat (I’m gluten free) because I got my ticket through kayak, but they tried their best to find something to help me get through the long flight and I’ll forever remember their kindness.

We left 2 1/2 hours late. It wasn't the airlines fault but they did nothing to help the situation. Even water had a price tag. The next flight was better.

The flight was okay however, for whatever reason they were not able to check me in for all 3 flights that I had booked through them creating a big problem when I landed in Toronto, in addition my luggage never made it to Toronto as well. So overall experience was not good

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Was a really good flight and so fast always try to get the first 5 road if you can

Almost as usual, half an hour take off dilay, on the other hand - the checked in baggage arrived as magic super quickly. By the way - why do you ask to rate the food and entertainment on flights without them? at least offer the option of "Not Relevant" or similar...

Not constantly changing the price DURING a booking. Felt like bait and switch.

All very smooth airside. Check-in counters were understaffed. The wait is too long. Only two, then three counters were open. Waiting time of 35 minutes is too long. Pls review your rota.

Very fast boarding. Crew members were super nice. I loved it!

My luggage got lost and until today there is no solution to the problem. It's still missing

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

The whole checkin process was a diseaster! We were flying with Vueling! We had checked in on the app but still had to checkin at the desks with our 10kg hand luggage! The queue for this was 2.5 hours long, with no social distancing in the pandemic (Covid19). When we finally got to the top of the queue, our flight was closing also another queue was opened up! But if we left the queue we were in we would have ended up at the back of a different queue! This seemed pointless to be honest! What could have been done is a bag drop section of the checkin process (Like Ryanair has) it’s much more streamlined and quicker! After all this drama, we only had 15mins to make it through security snd passport control to make the flight on time! It was very stressful and very hot! I was so thirsty that I needed to buy a bottle of water at the boarding gate (to my surprise this small bottle of water was €5- a total rip off! After boarding (which was ok) we were looking forward to a nice cup of coffee on the flight as we usually do! It took the crew nearly 1.5 hours into the flight to get to our seats to serve us! The coffee was dreadful (a hotel type sachet of instant coffee costing €2.60) and a heart burn inducing Turkey, ham and cheese toastie (costing €5.50)! The horrified by the quality! Ryanair is definitely better on food quality, check-in and boarding experience and service, that’s saying something! The flight itself was grand (although lacking interaction from the pilot- which is always nice) it was a smooth flight! When it came to landing it was good but our baggage took nearly 45mins to come out onto the carousel in the terminal! And other delay! Overall I would be giving Vueling perhaps a 2 out of 5 overall! Not impressed!

Boarded in group three at Barcelona, which meant going from a gate outside onto a bus to ride across the airport to a plane waiting on the tarmac. When we arrived at the plane, crew behavior told us something was wrong. Bus driver would not let us off for almost twenty minutes, despite being crammed shoulder to shoulder. Eventually, we got onto the plane, but were then told that someone “forgot” to refuel the plane and the truck to do so had not arrived. We departed late enough that we missed our connecting train in NYC, which was the last train of the evening, so we had to stay awake all night in the passenger waiting area of Amtrak’s Penn Station, which was almost impossible to get to because the station was now closing, as it was after midnight. We had to haul four suitcases a few blocks on city streets in the rain to get to the one remaining open entrance to Penn Station. We ended up being up for 36 hours straight because someone couldn’t do their job. Never, ever again would I fly this airline.

All four segments of my trip on Iberia were late for various reasons. No apparent effort to stay on schedule. Never flying Iberia again.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Without any prior warning, I was seated in a row just in front of an exit row (27F), and I had no idea that my seat would not recline. However, the person in front of me did recline her seat, reducing my space. And because I could't recline to regain some space, it was my WORST flight ever.

Overall it was okay. Just the lost baggage and how they are handling it

Puddle-hopper. Quick-ish flight. Don’t expect to have much/any in-flight entertainment (movies/TV, etc).

Worst flight I ever experienced, what was supposed to a 7 hour flight ended being 13 hours on a plane with no ac and the worst cabin I have ever seen. Never again.

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

Boarding was 2 1/2 late no explanation Captain said he did not know why, but he rested at home for an extra couple of hours. Food was edible, Nothing more.

It was a wonderful experience with great food, great staff, and no difficulties boarding!

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

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

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

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

all fine - did not have food - there was no entertainment

Delayed flight. Received notice from ryanair by email and via app but no such timely information available at airport from monitors or staff

This was yet another excellent experience thanks to Ryanair, it's ground crew, cabin crew and air crew. Although our flight was delayed by about 15 minutes due to the late arrival of the inbound flight, the crew did their best to successfully minimise the delay with courtesy and efficiency. I also commend Ryanair for its choice of destination airport in this instance: Seve Ballesteros Airport in Santander is a modern, compact, well-kep and well-organised airport, where passing through security and passport control was a doodle thanks to its friendly and efficient staff. So take a bow, Ryanair - and keep it up!

Everything went according to plan. Check in, boarding etc all were very efficient.

Boarding at Arrecife was commended way too early. Far too long for elderly to be kept standing on their feet. Otherwise we’ll done to all staff.
