Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

The crew should demonstrate flexibility by moving a screaming infant to its own seat with 1 parent

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

Small plane. Tight seating . What can one say except that it was fast!

The flights are literally always delayed arriving, boarding and taking off so they are always late for the connection. I planned ahead so I was okay but many others aren't. The food was terrible. The staff was very pleasant. I appreciate boarding back to front.

All aspects were excellent - it helped that the flight was only 2/3 full and I had no one sitting in my row. The Pre-check (US Passport Control and Customs) in Dublin made everything so easy when we arrived in Chicago.

Very nice experience. Flight had good entertainment system and good food options. Customer service was very friendly and nice as well.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.

My flight from Dublin was delayed two hours which ment that I missed my connecting flight to Phoenix. American Airlines provided a hotel room and rebooked my flight for 7:30 AM the next day. I didn't get to the room until 11 pm and I had to be at the airport the next day by 5 AM. The airlines did their best but the schedule was challenging for an 81 year old.

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.

I like Aer Lingus so that is why I’m writing this critique so they can become better. The boarding gate was too small to board properly. Our seats were toward the back of the plane knowing we would be boarding after business class, we moved to that area after business class boarded. An Aer Lingus employee told us we couldn’t stand there. We explained we were the next group to board and wouldn’t even be able to hear when our boarding was called. She didn’t care and was not very professional. The cabin was freezing. I wouldn’t feed my dog the food. We were over an hour late coming into chicago because of weather which can’t be avoided. I asked the crew if they could make an annoucement for before whose final destination is chicago to wait and allow the people with connecting to deplane first. He said there are a lot of people with connecting flights. He said, it doesn’t matter. Well, yes it does. He could have been more considerate of his passengers.

The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again

Very pleasant staff, there was some turbulence but the captain was very apologetic and gave notice where possible.

The ticket was reserved in my name but not paid for by underpricer. Alaska airlines was unable to issue my ticket (could not connect the ticket with the PNR) due to an error with underpricer and I spent the better part of 2 hours at the ticket counter trying to rectify.

Terrible way of boarding in Reykjavik. Seats comfortable. Meal was good.

Unlike my prior three connections on this latest journey, this flight was fairly good. Only issue was boarding as it was once again one of those Icelandic issues of bunch up, walk in the rain to a bus that then has you run up three flights of stairs to board the plain. I was in Saga class but the bus scramble eliminates any chance you get on first and have to then find a place to squeeze your carry on into an overhead that the people in economy populate so they can grab it on their way out up front. But unlike other Icelandic flights this journey I did find more the of the business class like accommodations then the other air segments. This one found a pillow and blanket waiting for me and I actually received a small cup of sparkling wine and had a bottle of water in place. Service was attentive and the flight departed and arrived on time. Received a menu and had choices of a hot or cold meal. I choose the hot which was cod and it was good. Decent size portion, salad and a choice of dinner rolls. Beverage menu was a selection of wines, beer and soft drinks. Desert was a small Tiramisu. Overall the six hour flight was a good experience for the price point.

We paid for saga class, which is the business class for international. My seat was broken and did not recline and my monitor for in-flight entertainment was broken.

At least one soda free, felt like I was nickeled to death.

Was a bit surprised that Icelandair flies a domestically configured 757s on long-haul flights to Iceland (no lie-flat seats in business class).

Comfort of seats is not good. Like sitting on a rock for 6 hours. Also no in flight food and limited beverages unless you pay is not nice. Need flight to be dark during the “night” but attendants don’t ask for shades to be lowered..

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

Well! They got me as far as Iceland, let me wait around at the airport since my next flight had either left or canceled, finally gave me my luggage, and sent me to wait quite some time with seven other people for a ride to a hotel. At the hotel we got a chef's salad, a nice room for the night which unfortunately had feather pillows and duvet (allergies), a really great and spectacular buffet for breakfast (small but stunning), taxis back to the airport for the 9:30 Delta flight back to Minneapolis. The Delta flight has free food and liquor included which Icelandair does not. All in all, it falls far short of my worst ever United flight to SGN. Icelandair did change my reservation after my roommate tested positive for COVID and we canceled our plans to travel around Iceland, but the charges were fairly hefty. I had trouble contact Kayak's agents to discuss changing my reservations and finally contacted Icelandair who changed them. (I used their contact form and put in several requests for call backs.) Of course, they called just after I made the change with Icelandair.

We had to be bussed to the plane. And it was raining. Not a pleasant experience.

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

I enjoyed the flight. I did find it strange that when I arrived at my seat although I had paid for a window seat that I was assigned a middle seat. Thankfully I was between a couple and they wanted to sit together. Please do a better job with this BA!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

The lack of organization at the boarding gate was shocking. It was impossible to determine where the line was and it was hard to understand the announcements. It was so confusing that my wife wanted to get on the wrong flight. I am also annoyed that BA is adopting the sleazy policies that the budget airlines invented of charging extra for even the first checked bag or choosing your seat.

My flight was cancelled and I was rebooked onto 2 flights on American Airlines: one from Heathrow to Charlotte and then one from Charlotte to Tampa.

My flight out of Miami was delayed by 2 hours which meant I had to quickly make other arrangements for pick-up in Glasgow. A $9 voucher for food was issued. That’s not much of a gesture in my opinion.

We were never contacted that our flight from Glasgow to London was delayed. Got to airport six hours early to find that we were going to miss our connecting flight to BWI. Our flight is scheduled for two days later and they only gave us a voucher for one night hotel. E we’re delayed on the front end too and had to fly to Edinburgh instead of Glasgow arriving six hours and taking a $200 cab!

The crew were very friendly and helpful. Also, the airline was very strict and not very helpful when I wanted to start by boarding from Heathrow airport instead of Glasgow international airport. I stayed 10 hours in the airport and no hotel or any form of compensation was provided. That sucks.

Flight canceled two hours beforehand, BA reticketed us so that we would have had to leave from Edinburgh instead of Glasgow, where we were already at the airport. We would have arrived in Boston too late to get home to Vermont. Instead with some pressure we were reticketed from Glasgow on Lufthansa, which avoided Heathrow, a great benefit after our horrible experience at Heathrow when we arrived in Britain three weeks earlier. (Kayak assebled an itierary that did not leave adeqate time for the connection at Heathrow, where thousands of people were trying tio get through inadequate and badly staffed security and staff did not know the slightest details about where and which lines we should get in.) The British Airways travel experience is not to be recommended these days.

Sitting in the plane for an extended period of time was very hot and uncomfortable. Very late arrival happened to not affect me but many others probably missed their connection because it also took a long time to get to the terminal.
