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.

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.

This was an older airplane. The cabin was constantly warm to hot throughout the 10 hour flight and there were no vents to personalize air flow. Also since it was an older plane, the material and comfort of the chairs were very uncomfortable. I left my flight with major soreness on my tailbone.

I dread trans-Pacific flights. They are very long. This was my first time on Universal, and it was my best crossing ever. The staff were professional, the hospitality was great, and the food was delicious. The entertainment system filled the long flight hours. I will seek out Universal flights from now onwards. 🙂

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.

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.

IAD with the archaic people movers is just a place to be avoided.

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

The trip was mostly nice, till the last moment when they had some issue with opening the flight door. The flight arrived late by 10 minutes, which was ok-ish, but then we got stuck on the plane for 35 minutes at the bridge and that costed our connection flight to LAX which left with 12+ passengers still on our flight. It added 2 days to our trip home, and we had to make lots of rearrangements to deal with the ripple effects. Don't book a 1+ stop trip with a layover time less than 2 hours.

My seat was broken. No sound available and the armrest between my wife and I was broken so it could only fold halfway up. Seats were a big close together so they felt a bit claustrophobic. Boarding was a little frustrating in Dublin as there is not sufficient room to actually queue up. Boarding was also frustrating for people behind me who were unable to use the overhead due to people abusing the privilege and putting more than one item each up there. Staff was friendly and helpful to those people.

The staff was amazing, so friendly and responsive. Check in was tedious as the online service was not available and the desk understaffed. It took a full hour in line to check in. The seats, in economy, where quite spacious until the people in front of us reclined their seats which then meant the seat was touching our knees. The inconsiderate people who were seated in a bulkhead kept their seats reclined for 80% of the flight and then got annoyed when we bumped their seats while shifting positions. It was highly unpleasant..

The connection time between the regional flight (from Newcastle) to an international flight (to The States) was too short. To require as second security scan and customs clearance within an hour and 20 mins is not enough time to make the actual connection. We had a final boarding call the minute we walked out of US customs and had to sprint (with two small children) through 20 gates to make it in time before the door closed. The concept is great in theory to clear customs before leaving Europe, but the timing needs to be adjusted. We travel abroad frequently and won’t be using this route again. Thanks.

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB flight

I was not admitted to the flight!!! I need a refund for this

Well, I think we left close to on time. Crew was “eh”.

This is a bit of a rant, but I'll try to keep it civil. The flight was delayed for 2 hours with almost ZERO updates from agents. Just "there's technical issues, we don't know if or when it'll be resolved" once an hour maybe? And the gate signs, and app never updated to show the delay until it was finally resolved. So when I called Aer Lingus to see if I could rebook, I had literally the dumbest conversation with the person on the phone there where he says "It's showing your flight departed at 11:10. So it's already departed!", where I responded, "Well, it's 12:45 and I'm on the phone with you, standing in the airport, staring at the plane. So...I'm not sure what your system is saying, but we aren't in the air right now.". He said "Nothing I can do. Since it doesn't show delayed in my system, you would be charged to reschedule." Once we finally departed 2 hours late, things were going smoothly as I would expect, except in another very strange way. The stewardesses were rolling the cart down the aisle offering drinks and I asked for a water, to which they said "Sure, you can buy a bottle". I'm not sure if this is an Aer Lingus thing. Maybe something I'd expect from Ryan Air, but for a 3 hour international flight, to not have complimentary water available for customers is an absolute first, in 15 years of flying for me. I'm not upset with the plane staff at all. They were very friendly, but Aer Lingus' policies, how they handled the delay, and the unbelievable conversation with the customer service representative, leaves a lot to be desired in those areas. Also, I'm not upset about the delay. Things happen. Technical issues. But this is a place where airlines really need to clearly communicate with their customers. They also changed gates from 12N to 13N and there was no notification on any app, or announcement over the PA. End of rant. I hope they get some feedback on how to improve communication, because otherwise, they were great. And the second leg of my trip was incredibly smooth - no nickle and diming water, no communication issues. Very professional and efficient and even landed early

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.

Horrible! I spend in airport from 9:30 and till 2 am. My flights and connections was delayed, rebooked and after was delayed, I couldn’t get home! I was stuck! The money I paid it’s to much for what I got! 💩 never again flying with your company! Second time booked with you and second time lots of issues. I rather pay 100$ more but be on schedule and time!

Friendly, professional. Everything went smoothly and pretty much on schedule.

Leaving the same day as planned would've been better

No internet, not even westjet connect makes for a boring flight

Our first flight from LAX to Winnipeg was changed but you never informed us at all. It went from a nonstop flight to a stay at Calgary. This impacted our trip negatively as we arrived much later than we planned to. Our returning flight was horrible. The flight was delayed 6 hours!! And we were NOT going to wait that long. The only way we got on our original flight was running there. However all of our suitcases were now coming on the delayed flight. It was the worst experience we ever had flying. I want my money back.

Be on time late arrival missed connection arrived five hours late to destination

Missed the connection due to previous flight delay. Can't rate a flight I was not on

Everything was good except I was a bit disappointed that I had to pay US $150 for bags.

They cancelled and moved my flight with no email or text or any other notice. I discovered this only when I attempted to check in for my flight. Actual flying experience was above average.

Flight was from Detroit to Richmond, not from Atlanta. Only coffee, tea and water were served since it was a short flight. But I really could have used a coke!

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

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

The flight crew was kind, flexible, and accommodating. The seats on the plane were extremely uncomfortable.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

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

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?
