  • If you are planning on doing the famous Ring Of Kerry circular route, which is a scenic loop drive on the Iveragh Peninsula, then you should fly into Kerry Farranfore Airport (KIR) or Shannon Airport (SNN); these are airports that are close to the start of the circuit.

Cons: "Ran out of business class meal. Substituted a Econ class."
Pros: "Reasonable space in economy class seats"
Cons: "Staff hurrying us up 40 minutes before departing and threatening to take our bags out of the plane in case we didn’t board then. I had to leave my coffee and run."
Pros: "Crew was helpful and food was very good"
Cons: "There was no entertainment on the flight from Vancouver to Amsterdam and this on top of a two hour delay in taking off which led us to have to literally run to our gate in Amsterdam to make the connection to Mumbai"
Pros: "Crew was amazing. They adjusted the seating arrangements so there was an empty seat in every row to give passengers more space. Very thoughtful and much appreciated. They served delicious meals, snacks, and water. They provided headphones, blankets and pillows. They took very good care of us."
Pros: "the trip was excellent and comfortable. LOved the windows that shaded out rather than the having to pull down the plastic blind. entertainment on board top notch screen huge One hostess , Helen was absolutely fantastic and the best I ve had on my many trips. I will recommend KLM whenever I can"
Cons: "the headrest is hard. Apart from that- all was fine"
Pros: "The crew was great but the seat wasn't as comfortable and didn't have much leg room."
Pros: "Nice aircraft"
Cons: "Unexpected refueling stop. 2 hr delay Lost connection Reached destination after 18 hr delay"
Pros: "Crew was nice and friendly"
Cons: "Airplane so uncomfortable. Food horrible. Not even available for one of us what we ask for on what was offered. Bad taste and not what can be on a that length of time flight."
Pros: "Being fed was amazing and watching free TV was great!"
Cons: "I wish there were personal fans because it got uncomfortably hot sandwiched between people"

Flight was ontime, clean, staff was friendly - there was turbulence but can’t avoid that (it’s a flight 😉)! The staff were attentive but would be nice if Aerlingus didn’t charge for coffee ☺️ but overall I enjoyed my flight experience and will travel with them again (Ireland’s Four star airline

Cons: "The flight attendants were just awesome. First time flying with Aer Lingus and I must say they are my favorite airline henceforth"
Pros: "The entertainment was great and the crew, for the most part, was pleasant."
Cons: "Leaving on time and the consideration of connection flights and how it inconveniences your customers when this happens."
Pros: "Nothing since I’m still in dublin"
Cons: "There was minimum help. Wait actually, in Manchester there was none. No one at the gate until 2:15pm when the flight was already 20mins late! No one updated an incoming flight with passengers needed to make connections."
Pros: "This was my first flight on Aer Lingus and it was excellent. Prompt take off and Dublin Airport is modern and extremely comfortable. I plan on using this airline again. Flight attendants were polite and helpful, as well as check-in personel."
Pros: "We were at front"
Cons: "Tight seats, boarding line held in confined area on stairs before boarding"
Pros: "Overall, a perfectly serviceable "domestic" (i.e. intra-EU) flight."
Cons: "Long check-in line at Aer Lingus desk at Munich Franz Josef Strauss due to one of two check-in agents apparently being late to work. This agent was also brusque to the point of rudeness when checking me in -- and was checking personal messages on her phone during the process."
Cons: "My granddaughter and I were seated with a guy who reeked of really bad body odor that I was retching in my seat for the whole flight. The flight was full."
Cons: "I booked this in March and was seated 20 rows away from my wife who was on the same itenerary. Seats were cramped and uncomfortable and the food was terrible"
Pros: "Nothing really. The price was good, but only a little cheaper than others. I will pay more next time for sure."
Cons: "Hot plane (no air vents). Rude attendants. VERY small, narrow seats. They removed a few bathrooms for more seats (rows without windows now). There was nothing to like. Nothing. I was on the IAD to Dublin flight (and back). Delayed flights both ways."

British Airways is consistently fine, in terms of the on-flight service. Heathrow Terminal 5 can be difficult, though that is probably not BA's fault. On the other hand, British Airways' service has routinely been difficult for me the past few years. Indeed, it is a reason why I am considering changing carriers.

Pros: "Crew good, food okish."
Cons: "Entertainment system below average. Disembarkment was poorly handled and resulted in big delays."
Pros: "I enjoyed the entertainment meaning movie selection and staff was real friendly. Plus flights were on time."
Cons: "The seat need more cushion especially for long flights and more leg room. Very uncomfortable after awhile of prolonged sitting."
Pros: "The customer agents were helpful and just great"
Cons: "That out of 4 agents and the manager one simple agent wasn’t as nice"
Pros: "Excellent service from all British Airways crew that we dealt with"
Cons: "Lost luggage. One of our suitcases never arrived at JFK. A lot of food was served which was nice but quality of food was mediocre. Very high salt content. Not many options for diet restricted travelers."
Pros: "For a short flight it was very good. The crew were very accommodating. On time. No delays"
Pros: "I loved the new modern plane. It was a bit more comfortable and conveniently designed. Less like a cattle truck and more like a luxury bus."
Pros: "Hospitality from Crew members. Food."
Cons: "24 hrs delay for boarding this flight. No wheel chair provided though I booked."
Pros: "I recently had a difficult time returning to Italy and the part of the journey handled by BA was excellent. They were kind and helpful."
Pros: "Only good thing was that British Air didn’t crash us"
Cons: "British Air overbooked the flight; I checked in on time but there were no seat assignments left. I went to the gate anyway to try; the gate attendant kept me waiting for a seat so long that the gate closed. He was not nice. His colleague booked me on a different flight to LCY airport (instead of Heathrow). But that different flight got diverted to Manchester. So the fast that BA overbooked cost me an extra 6 hours and $140 to buy a train & tube ticket to get back to Heathrow. The fact that there was not a single smile among the staff, and I had to argue to even get on the second flight, is inexcusable."
Cons: "First of all, we've had to pay registration fee 55 Euros each, just because we didn't check in online! What the hell is that? Secondly, the seats that I paid for were not available! Lousy service..."
Cons: "Everything, basically... The flight was delayed almost an hour, boarding was uncomfortable, there was no food service on board, flight attendants were less than friendly, and takeoff was shaky and turbulent."
Pros: "Price of flight was good."
Cons: "Price of snacks is a rip-off. Seating is cramped."
Pros: "All but one crew member where excellent. But the one girl. Made it perfectly clear that the passengers where an annoying part of her job not a pleasure. She had a sour face on her all flight. Everyone was talking about her."
Cons: "Seating is always uncomfortable on these short haul flights."
Pros: "flight on time"
Cons: "priority passangers can board first, but must wait half an our standing up in the corridor. I do not understand this and what the advantage is. next time, I will wait in the chairs until the last ine, because you already have your seat number."
Cons: "The seats are uncomfortable and the baggage policy is a rip off and not consistently applied. Those only permitted a small bag in cabin not policed with much larger bags than allowed permitted. Some wheelie bags tagged and charged for as too big. I wanted a hold bag of 20 kgs but was charged for two"
Cons: "The app wasn’t working to check in. We arrived to the airport 1.5 hrs early only for them to tell us that there would be a $56 charge for not checking in 2 hours ahead of time. This is absurd. Almost as much as our ticket to Mallorca. Not okay. They were so rude to us and I dont trust that they will do this again to us. It’s a scam in my opinion. Definitely read all of the fine print or they will rip you off. Oh! And we paid for PRIORITY boarding. Psh"
Pros: "Price - That is All"
Cons: "Delay, Checking, Plane is Old and Seats do not Recline, Children Screamming, etc"
Pros: "Nothing"
Cons: "You have to pay to check-in at the airport. And they make you go to another line to check in again. Also when I weighed my luggage it was 13-kilos which means I could have it as a carryon. But at the gate they made me pay another 50 euros for my luggage"
Pros: "Nothing, even the €5 voucher barely got a cup of coffee at a Starbucks that had us waiting 45 minutes in a line to order"
Cons: "The flight was listed as delayed with about an hour before it was due to arrive. It landed 3 hours and 45 minutes late. Up until 2 hours, in other words when it left Stansted for Nice, there was no explanation as to why. The Stansted Express tickets we paid for an hour before the scheduled take off had to be forfeited Upon arrival at Stansted Airport, we were made wait for our plan to taxi to its gate, wait to get off and then wait for our bags to arrive which took well over an hour. Between Stansted Airport, hailed as one of the worst airports and Ryanair, who’s cabin manager was a clown, the whole experience start to finish as a fiasco!"

We bought tickets for £30 from kayak but we paid £55 for check in to rayan , they slaught us

Flight was delayed so long we missed our second flight. Entire trip had to be cancelled. Ryanair refused to help us.

Stanton airport is outdated, pure equiped, airport. Fire alarms, power outages is a common routine, wich result ir flights delay , additional money spending and huge gathering of people in airport wich is unsafe.

After you made us check-in I tried to add a suitcase in the internet and also to get help by chet. Nothing work and we pay 60 pounds at Airport. Comper to Easyjet to do the same, was easy and customer friendly.

Boarding was like being hoarded like cattle, all penned in in an area way to small

I missed the flight from Manchester to Dublin because of poor informations from Aer Lingus and the airport, no possibility to check in online, they don't respond to phone calls, I had to buy another tickets to enable me travel to Dublin from Manchester. I want my money to refund.

I were there 20min before departure and they didn’t let me on the board with 5 other people, after all they admitted it was their(Ryanair) fault.
