Reviews of the top 4 airlines serving from Ireland to Las Vegas
It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.
It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.
Very disappointed in the crew as they did not pick up my trash nor offer headsets
First The flight got delayed because one of the crew members was late and we couldn’t board until she arrived. Then we all boarded and got held in the tarmac for another 30 min.
My service light was on 15 minutes before I had to get up and find a glass of ice. And I was in business class. The meals were not for either my wife and I. She did not eat the entire 10 hour flight and I managed a bowl of soup. I was expecting much more from business with what we paid.
The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..
It was delayed but other than that it was great.
Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.
There was supposed to be a meal served, but there wasn’t and the major toilet was out of order
At first, we were on the runway for about an hour, literally. The Captain did explain that the Control Tower just had a change shift (sounds like an unrealistic excuse) and then that we had to change a runway. A regular economy seat is made for 12 yo twiggy. I understand Delta wants to push for an upgrade, but after sitting in a Comfort seat and in First class. I would say First class is not worthy of my money. The landing was delayed because of the weather in NYC, I don't hold that against Delta, of course. The Captain did alert us to that upon takeoff in Vegas and again as we reached NY.
The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.
Didn’t have requested food and seats could be more comfortable.
Flight attendants on this flight were very lovely. Hot food was terrible. Canned wine felt elevated and was GOOD. The aircraft was overall not very clean. Although this one was much more cleanly than the flight from Pisa. Pilots were great & landings felt smooth and safe. As I mentioned in my last review, this was my first time flying aer Lingus in many years and I cannot say I will be rushing to book again. This airline needs a real facelift.
Everything went extremely smoothly! They boarded by groupings of seat numbers starting from back to front. All staff very helpful and accommodating. Food and beverage plentiful and good.
The plane from Venice to Dublin ran out of food. They did not restock the plane in Venice.
It was very refreshing being in a nice and clean plain, with pillows and earphones that you don’t have to pay for, with warm food and beverages and a very nice crew
The thing thy call a pizza was atrocious. Do not eat it. The seating is as usual for economy an experiment in cruel and unusual punishment that they aren't allowed to do to prisoners but you get to pay for it.
Didn't make it to this flight as we sat on the tarmac for 1.5 hours.
The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.
Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly
Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.
The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.
Mostly great. Only issue was with the WiFi. Halfway through the flight it was spotty and I was unable to work as I planned. This impacted my work products as I am traveling for business and it was an unexpected hindrance which was inconvenient. Flight here was amazing. For a 5 hour flight something more than a Biscoff would be nice but I’m just swinging at windmills I guess…
Better service. No food options, but we did get drinks and a cookie.
We were 4+ hours delayed. AA is absolutely obnoxious. They just kept pushing back the time to the point where we did not get into Vegas until after midnight when we were supposed to arrive like 845pm.
We will be writing a long, detailed letter to corporate about our awful experience with American airlines.
Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.
I was a little disappointed of not having an android charger. Only one it was for an iPhone. I've flown American in the past and had access to one.
Almost everything was outstanding. First, we boarded on time and the flight crew did a great job getting everyone seated. Then the pilots took their time and care to make sure the plane was full de-iced three times as there was a bad ice storm a few hours earlier. The plane ride was smooth and comfortable and even the economy seats had decent room and comfort. Flight Attendant Lisa went above and beyond to make sure I was comfortable - she is outstanding. The only thing wrong with the flight, and it is something which needs to be addressed, is that the gate to gate time was over 6.5 hours and not one meal was served. The only thing offered to eat were two small cookies for a transcontinental flight - unacceptable. Charge me more but give me a meal for a long flight. Thankfully Lisa found something for me.
I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.
First class flight attendant was rude and lacked any customer service skills.
Very good baggage check and boarding pass service at Heathrow. Boarding was well organized, given the number of passengers. Food was very good. Cabin temperature was lower than expected and we were not prepared. Overall good experience.
one meal and one breakfast or sandwich instead of two meals.
Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.
You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.
Premium economy was not what was shown, no leg riser, seats were broken and do not recline more than economy, food, we couldn't eat it was so bad, no menu 1 item and it sucked.
Online check-in not available from Istanbul to Las Vegas. The check-in process at the airport was extremely and inefficient period. Took us over an hour to check in. Besides that, everything else about British Airways was good
Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.
My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.
My luggage did not make it. Will avoid Heathrow and British air
Overall flight experience was good. Unfortunately our process getting to our flight was a hit or miss. Our flight was delayed perhaps for the best as getting from terminal to terminal is very long and security had problems with the machines that delayed us getting to our flight. Heathrow security could care-less that you have a flight you are about to miss!
