Flying direct to Dublin and using it as a hub to other European cities is fantastic; far better than going thru Heathrow, DeGaulle or Frankfurt.

Don’t sit on the inside seat during a lay flat flight. Don’t order the beef short ribs, they’re kinda fatty, and chewy.. Try all the whiskey.

Avoid Toronto airport if possible. One had to leave the airport to go to the next terminal. No directions.

If flying to Ireland, the direct flight from SFO to DUB on Aer Lingus is the way to go to avoid the hassles and uncertainty of mid journey stop-overs.

Look at Jet Blue and Delta. May be a bit more expensive but keep an eye out for fare reductions and book early.

Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.

Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).

Go to the airport early, LAX is the worst airport to fly out from. There is just so much traffic on the way to get there. We used the flyaway option in van nuys, ( buy your parking ticket in advance) costing us only 115 dollars for parking for over two weeks and it’s very secure. The buses go every 15 minutes from there directly to LAX. Best way to get to and from LAX. Check in was easy.

JFK is an amazing airport, they have TSA precheck which was not offered when I flew Aer Lingus/Newark. The TSA precheck line took a long time, they only had 2 machines and a few agents working. Other than that Newark was as any other airport, easy bag check in process and gate seating area was clean and comfortable.

Pack what you need in a carryon since it is likely you'll arrive without luggage.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

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

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

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

I travel frequently. The flight was late again... KLM should really try and be on time

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

One of their staff was so rude with discriminative. Such a reputed airline shouldn't hire such kind of arrogant attendants.

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

Better seating for sure. The seats were so close together for such long flights.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Wonderful and fast TSA checkpoint. The line was fast and our gate was close by

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

How they treated my luggage was horrible. And foods are not edible… Flight attendants were not listening my request. Etc

We were already two hours delayed before take off and then had to be diverted. Terrible experience.

Baggage handling was poor. Baggage was delayed. Communicating updates on finding and delivering the baggage was poor.

I love flying with them, the long-haul was fantastic. The short flight from Dublin --> Switzerland was horrible though. Most narrow seats I ever had, first and only time in my life I couldn't even close the seatbelt in seat 1A which was very embarrassing so I had to sit in the middle, because that seatbeld was 20cm longer. No idea why seat 1A would have a much shorter belt, it's just ridicilous. Also I hate the fixed seats, way too narrow.

Despite me ordering a gluten-free meal, they had nothing on board. If you have health restrictions, be careful! Otherwise just fine.

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!

I was not permitted to check in online and there was no one at the check in desk at FCO when I arrived, so I could not get to my flight. Did not receive compensation of any kind.

Boarding was messy and the flight was delayed an hour

Food was mediocre, but as expected in economy class on an airline. Wrap was ice cold , my son’s served by a steward on the next aisle was warm . As expected, but at least heat the food up a bit. No frills, but it’s economy. Excellent free WiFi was a bonus

The overall sports experience wasn’t even OK. The fact I canceled when I was on my way to get food at the airport again this was a international flight. I was out of the country and I did have work the next day. It was very inconvenience and very last minute and it was very poorly communicated.

Informed of delay the day of flight resulted in us getting to our destination hours later. Had we been notified earlier plans could have been rearranged. No airline employee could tell us why there was such a delay. Smells of trying to hide the real reason Food was not offered to us. Stewardess walked right passed us offering others drinks and food. I thought on a short flight maybe they paid for it so I didn’t ask. Turns out they should have offered us something Seats were very hard and uncomfortable

Terrible. The flight from Athens was delayed and we missed the connected flight to USA. They will put service was unacceptable, we had insufficient information, and the whole experience was awful.

not able to change flight, no customer service from KAYAK

Food abd wine was good and for the price this was a true bargain, relative to other transatlantic options. But it is still significantly behind my experiences with Air France long haul in both hard and soft product. But for the price air Canada to Europe from Vancouver is currently the best value of quality for the dollar cost.

Very good except paying twice for seat selection. Once when I booked and again when I checked in.

I think it went very well. We flew international and felt safe and well cared for. We were on time both leaving and returning.

No issues with the flight and flight crew. cleaner seats in economy section would have been better

We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

I didn’t get to go on my flight. I cracked a rib and tried to contact kayak Air Canada and United Airlines and everyone gave me the runaround. No one reached back out to me and I couldn’t go on my trip. I have used kayak in the past to book flights, but I will never do it again because that experience of trying to get a hold of someone to explain my situation was awful. Everyone gave me the runaround that I did speak to and no one was helpful and kayak was unreachable.

In flight entertainment is complex but extensive. The flight was 2 1/2 hours late-initially announced with 20 min delay-. Appears to have been weather related. Check-in staff very helpful. Needed wheelchair assistance-efficient in Boston, slow but very helpful in YUL. Given the delay would have appreciated refreshments on plane (more than a tiny packet of pretzels). Plane was clean and apparently in good condition.

We were an hour late on the flight back, quite inconvenient !

Flight was cancelled on the departure day. We had to drive an extra 250 km to make it to another flight that was also cancelled. Finally booked on another flight that was also delayed 1h30...weather was fine on all flight. Every delay because of technical issues. Horrible experience.

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

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Dreadfully long wait for bags at Dublin coming off an already late flight.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

Aer Lingus was the actual airline so they handled everything professionally.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

Excellent service smooth flight f or the most part food was right now.I'm expectedly good.

The flight was delayed, and delayed some more. But there was more room on this plane than the one that flew oversees! There was no food or entertainment, but that’s ok, it’s a short flight

Was delayed for checks after evidence of bird strike, good call
