Get there early. Nice airport options while you wait.

Anticipate delays, prepare for long walks through Heathrow to baggage claim or for connections.
Verified travelerFlew with United AirlinesORD-LHRJul 2024
Even though you may have a delay or two the important part is that you arrive safely from one point to the next. I wish I could get some credit back since I paid for a nonstop flight and ended up having a connecting flight.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Boarding uncomfortable. Stewardess said I would have to check my carry on as there was no room in the overhead bins. Another passenger helped me find a spot.

Any flight that lands safely is a good flight. However our leg from Helsinki was delayed 1 hour with no explanation. The delay would not allow us to make our connection to Cincinnati. I was informed by American Airlines that our Cincinnati flight was rescheduled for the following day. I immediately made a non refundable hotel reservation in Dallas. Upon exiting the plane at Dallas I was given a hotel voucher. Nice, but I can't get a refund on the hotel I booked. A little communication would have been helpful. Food on Finnair is below quality of Korean Air.

The cabin crew really looked like they wanted to be somewhere else. They weren't really interested in providing an attentive service to full fare paying passengers at all. However the Captiain's in flight announcements were relaxed and very entertaining.

Crew were professional and responsive. Food was mediocre and breakfast could do with revampinmg

Food was very ordinary for premium economy, very small portions.

i dont know WHY they call it business class. the seats are NOT significantly wider than economy seats, they just do not let the middle seats be beepked to give the illusion of more space between passengers. the seats do NOT recline any more than economy seats either. the only real difference is the full meal served to business (vs none for economy). I would rather have a wider, lie flat ACTUAL business class seat with no food for a 3 hr flight. this was pretty disappointing to say the least.

There wore nice leather like sits, in my opinion seats lay out bit tight . Crew was great they did averything possible to make averywone comfortable as possible, food was, think worst I ever head on flight, head chicken and yellow rice. Ice cream was a nic treat.

Our previous flight was delayed but they waited for us to board.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

My American Airlines flight was deleted and you guys never let me know

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

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

The flights were in time and the bags arrived. well done

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

Overall good. I was surprised how easy it was to get from plain to plain in such a short time. Food choices were not so great and quite expensive. Entertainment was ok. Flights were smooth.

Our three ski bags did not arrive and are still not delivered, one full day later. With one ski bag not traceable at all. I would not fly Iceland Air again.

Horrible. The flight was delayed by over 3 hours but updates were barely provided. Boarding started 3 hours late then stopped because their system crashed. So now, passengers were standing for 15 minutes in the open waiting to get boarding passes scanned and get on a bus. Duty-free closed around 4-4:30. Only 1 food outlet was open and it was super slow and busy since it was serving passengers from multiple flights. So a number of passengers couldn't buy meals at the terminal. Since the flight was delayed by over 3 hours, we could have been offered snacks on-board. Nothing. The seats barely reclined. In-flight entertainment options were pitiful. Overall, a miserable experience. Never flying on Icelandair ever again. :(

Again, lines for boarding are a problem in iceland. The flight itself was fine and very smooth. No complaints. We would definitely fly icelandair again.

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

Noted in last review. Good to know, though air Lingus on European flights does not offer any food or drink, even though we were on the plane for 3 1/2 hours from Naples to Dublin everything you had to purchase even water.

Seats were alarming close to the row in front of you. I didn’t do the measurements online, which I’m sure they’re available, but it seemed much tighter than other planes, but the airplane itself was well maintained and looked fairly new. My only complaint on the staff was that we’re on an international flight. Normally they give you wine with dinner and the flight attendant decided to pull some strict restrictions and wouldn’t give more than one glass of wine per person, and you could not share with your spouse, which seemed ridiculous when we have four people on the plane with us and only one person ordered wine asked for a second one and she said oh absolutely not. It’s only one per person Which on a transcontinental usually is not the case. They’re very attentive on making sure everyone is as comfortable as possible.

Boarding seemed a bit chaotic and we had to walk outside across the tarmac. Passengers of all ages had to drag carry on luggage up the outside stairway into the aircraft. There was no WiFi. Very uncomfortable crammed seats. Glad in-air time was only an hour!

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

There was no flight. I booked a flight from Toronto to Bordeaux with a stopover in Dublin. I arrived in Dublin and the flight number I had didn't exist and the flight going to Bordeaux I wasn't on. I had to book a new flight with a different airline for later in the day and pay out of pocket.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.

Everything OK , except the plane left more than an hour late so I couldn’t participate in an excursion I had that morning in Brcelona

Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.

very good all round. staff, food, entertainment, punctuality all very good

The cabin crew were great very helpful and accommodating. We had a fellow passenger throw up next to us. The flight crew did an amazing job cleaning up and reseating us. We did question as to if he should have been let on the flight as his condition was likely self imposed.

online check-in was horrible and didn't work either way

Horrible. Paid for seats for my family. Iberia changed planes and never notified us that the seats we paid extra for did not even exist on the plane. We were randomly placed on the plane. Thankfully, we were seated together. Upon boarding, my youngest daughter was pulled from the line and they just arbitrarily changed her seat 7 rows back from the rest of the family. I had to wait at the gate while they tried to see us back together. One of the most uncomfortable small spaces on a plane I’ve ever experienced. When I called Iberia, they first told me that no mistake was made that the plane was never changed. Yet my receipt for my paid seats were for rows that did not even exist on this type of plane we were getting on. They said that they would reimburse my money and I would get an email, but I’ve never received any information or emails regarding a refund for the seats that I had paid extra for. Then when we arrived in Madrid, one of the pieces of luggage that we had checked in was damaged to the point that the handle that was stowed in to the luggage was broken off by the crew members handling the luggage. The crew on the plane was very nice, but as far as the rest of the experience, I would be very hesitant to ever use Iberia again.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?

Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier
