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).

Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.
JudyFlew with Air CanadaYYZ-DUBJun 2025
Seat room is very limited with econo. No need to pack snack…food provided.
Verified travelerFlew with Aer LingusLAX-DUBJul 2024
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.
Verified travelerFlew with Aer LingusEWR-DUBApr 2024
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.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

The person I bought the ticket for didn’t make the flight.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

My husband and I recently had an unfortunate experience with Lufthansa. At the Philadelphia International airport, the ground staff refused to board us because we didn’t have a current visa stamped on our passports for Frankfurt. We completely understand that this was our mistake. we should have double-checked the visa requirements before our trip. However, the issue that upset us most was how the situation was handled by the staff. They told us they would mark it as “boarding denied due to visa issue”, but instead they recorded it as “no show”. Because of that incorrect entry, our return flight was automatically cancelled as well, which caused additional stress and expense. Mistakes can happen, but we expected more transparency and accuracy from a reputed airline like Lufthansa. It would have made a big difference if the staff had been more careful and considerate in documenting the situation correctly.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

My flight was delayed about 1 1/2 hours in Chicago, but other then that it was a good flight.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

Terrible. Delayed 7 hours, and cancelled the flight, leaving me stranded and out of pocket $500 for an alternative last minute flight

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I had a positive experience on American. I'm blind and traveling with a guide dog and the flight attendants were so kind, friendly, and helpful towards us. They checked in on us during the flight and they made us feel comfortable and welcomed. There was an hour delay before depature, but overall the flight was a smooth ride. I appreciate that there were no issues on this long flight back home.

Disliked having to wait a little longer to disembark from the plan when we landed in London

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

Worst flight ever. I was suppose to have a 3 1/2 hour layover in Chicago but got to the gate 4 minutes before boarding.

Our flight was 1.5 hours delayed. There was no weather for the inbound flight, so I don't understand why. This meant a VERY late arrival and only a quick nap before my morning flight.

The flight delay in Dallas created a domino effect that impacted all connecting flights, leading to an increase in the number of connections. As a result, I missed my flight from Casablanca to Marrakech due to the tight turnaround when landing in Casablanca. CMN Airport was understaffed; only one employee was available to assist passengers while others just stood by and watched. It was an extremely frustrating situation. Many passengers were crying and banging their hands on the counter while talking to customer service representative Allabough. Unfortunately, Allabough couldn’t change my flight in the system. At the same time, I was on the phone with an American Airlines customer service representative named Solomon, who said he couldn’t make the change either. So, I decided to take an ONYA Voyages train from Casablanca to Marrakech to reach my destination on Friday, June 26. It turned out to be an unpredictable trip.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

It’s a great flight. Service is good. Staff is awesome.

It was American airlines and it was awful like usual...

More choices on menu. Seemed only thing offered was Scottish, and while that’s good for the Scot’s it doesn’t help the Americans who don’t like that food. And I really hate it when, during sleep time the attendants have a very loud conversation right over you. Lastly, I paid 5000 dollars for business class, and having to pay more to choose my seat early is really an insult. Seems greedy

It all went very well, except for the ramp coordination upon landing in Boston. That, however, was resolved in fairly short order.

NOTE. Aer Lingus does not accept American Express. I was denied boarding because I could not pay the fee for my oversized bag. I did not have another credit or debit card. Moreover, at CDG, I needed to check my bag at one location, go to another location to check my oversized bag and a THIRD location to pay for my oversized bag. Hence, once I was denied boarding, my bags were already en route to the plane. To retrieve them I needed to go to a FOURTH location in another part of the terminal. Last, Aer Lingus will not reimburse me for any portion of my ticket. I lost $1000 bc Aer Lingus doesn’t accept American Express at the CDG counter even though I paid for my ticket through the Kayak link with Amex. Kayak should remedy this situation if they want to continue to partner with Aer Lingus.

The biking process was confusing and I was called for a seat assignment from I number I repeatedly though was spam, but the flight itself was great

It was poor overall. They cancelled our flight and changed it without notifying us. So we incurred extra costs by having to book a hotel for our layover. They say it's Kayak/Underpricer's responsibility to reimburse us. But Kayak/Underpricer have said it's Aer Lingus' responsibility because they are the ones with our 'booking information.' I find this situation confusing and unacceptable.

My experience with Aer Lingus was not too good. First, because of the last minute delayed flight from Amsterdam to Dublin we almost missed our flight from Dublin to Philadelphia. Secondly, the flight from Dublin to Philadelphia had very uncomfortable seats especially it was a very long flight. My buttocks were constantly in pain for sitting on these seats for this long. Lastly, the service in the plane was also slow. I asked for a second cup of water and the hostess told me he'll be right back with that where it took him over an hour to come back with water. It was warm in the plane and I was very thirsty. Overall this airline needs much improvement in their services.

Staff was generally friendly and helpful. Attendants collecting trash were somewhat inattentive though.

This flight left about 45 minutes late, and arrived about 45 minutes late, which was enough to make us miss our next flight and trap us in Dublin for 24 hours!!

I think the extra charges for seating with no added advantage and the added charges for baggage are excessive compared to other airlines.

I had zero issues with the flight. I did have issues with the staff at the airport. We missed out flight due to a delay with another airline. Talking to the staff and trying to get a new flight arranged was challenging. One guy was able to try to help us and got us on a new flight, but other staff was dismissive and clearly let us know it wasn’t their problem. All I kept thinking was… this is why air lingus has such a poor customer service reputation. I will be avoiding this airline in the future.

Food was just okay. Was surprised initially when was charged for a cup of tea when they first came through cabin for beverages. I’ve had far better long distance flights ( take some tips from Swiss airlines)

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

Real smooth and easy, Real good leg room in coach!

Late departing. Late arriving. More worried about limiting bags on board. Free beer and wine a nice surprise.

The flight was delayed for 2 hrs. We were changed to a smaller plane, which was shaking a lot.

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

No TV's. Seats are super uncomfortable. Crew was great!

Terrible confusion btw air Canada and United. Wasn’t able to change ticket because I had purchased on kayak. Rethinking booking tickets on this site, and will try to avoid United and aircanada going forward.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

The AC check-in counter closed early and caused us to miss our flight. Our connecting flight arrived late, at 1300, so we picked up our bags and ran to the AC check-in counter, only to find it closed already, although our flight to Montreal was at 1435. We had already checked in online, so the AC staff knew we were coming.

The flight was delayed to 1:50 am from 12:05am which caused confusion for us on the connecting flight.

main meals are horrible but then you dont fly for the food

One of the worst experience given the middle seat even asked for the change no one honored,boarded at the end and overall one of the worst experience

I like the crew, very welcoming. Food can be better. The seat arms don’t go up so. I could use the empty seat next to mine to relax better. 3hrs delay 😠

They issued seat assignments and sat my 2 year-old in the row behind me, separate from me and my daughter. Communication/ customer service was terrible. They told me to change it in London, then in London, they told me to talk to the cabin crew, then a supervisor came and stuck us in the back of the plane when we were supposed to be in row 25. Overall, they need to really work on their customer service. Additionally the food was terrible and they ran out of meals and didn’t have any kid options. To top it off there was no in-flight entertainment for the first hour of the trip.

I was put into business class. Wow! My flight attendant was great! The food amazing’

Bag drop in Jersey was very long. British Airways could have had more people available to check bags.

Flight was cancelled at the last minute with no explanation. No viable alternative offered and zero customer service support. Totally useless.

The check-in of my luggage was terrible. When purchased my tickets, one luggage and one carry-on was part of the fight. My flight was switched from British to American Airline. During check-in of luggage at the airport, I was denied and had to pay extra $75. How do I get reimbursed for this extra luggage payment?

everything to do with KAYAK was terrible. Your customer facing departments are utterly useless, timewasting and unhelpful.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful
