Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

Flight ok, but me and other two passengers didn’t have connection with the entertainment in our seats. So, no movies, no games, no music… for 9 hours. The crew just told us that there’s nothing they can do but I noticed during the flight that there were empty seats, so they could have offered to us to change seats. Customer service could be better.

Had a nice flight to London on BA will fly with them again in the future

Finnair cancelled my flight 12 hours prior to leaving for Helsinki. They stated there were mechanical problems. I had to scurry around to find a new flight that would meet my needs for arrival in Helsinki. Luckily I was able to find alternate transportation through Lufthansa/United.

I’m very disappointed, to fly into an airplane for 10 straight hours, and not having a TV even though when I put the ticket I was told that I will have entertainment for the TV. Very disappointed.

Helpful steward. Allowed me to move to some empty seats and I was able to get some sleep. He also had milk for my tea. Americans don’t realise that cream or half and half ruin tea.

Very rude hostess. She embarrassed me in front of others. I went to sit after taking off in a different sit in the same economic cabin. Was the area where doors are. She come to me very laud and said: go back to your sit those sit are more expensive.wow! No diplomacy. Flight was super full except 3 of those sit. The only person in that row later during the flight occupied all sit laying down!. Once more disappointed at American Airlines. Early flight they lost my luggages for 4 days. Never refund money for replacement for some of essential items purchased..when I booked the flight I thought was Finlandair. I

The crew was very good, excellent, they help me with my needs.! Food was not that good.

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

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

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

We were in the last group to be called to the flight - which was 30 minutes late taking off. While we were lucky enough to have been given bulkhead seats (due to a medical condition I’d told them about beforehand) the seats weren’t particularly comfortable. A crying baby for the whole trip made things worse, so the crew managed very well with coping. The final thing I’d say was that there wasn’t enough food served during the flight.

Very good. Glad we had Premium for the flight out.

We flew Upper Class from London to The Turks and Caicos. Check in was amazing. Our ldriver too us directly to a special entrance to terminal 3. It took 10 minutes to check in and clear customs. Amazing! The VA lounge is large and comfortable. Boarding the flight was easy and without a wait. The crew was excellent. But the seats were awful, strange and uncomfortable. Having a comfortable flat bed seat is the reason we pays 1000s extra. The VA 787 uses a reverse herringbone configuration. Look it up. You have your back to the window and are facing the aisle with no privacy. Turning the seat into a bed requires assistance from the crew so not very spontaneous. . The food was ok. A bit tasteless and meager portions. Had to pay for WiFi. I believe VA has other configuration on their dream airbus flights. Lots of stuff about all this on YouTube where you can see what I have been describing. I can not recommend taking VA on a long flight with these seats.

From the start everything was perfectly fine. First meal was fantastic. Breakfast needs a lot of work and food was overcooked and not very nice for breakfast. Staff for a fantastic friendly nice we came round and check we need anything else to eat or drink

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

So so. Terrible aircraft choice for that leg of the flight.

Due to one crew member not showing up to work, our flight was significantly delayed causing us to miss our connecting flight in Houston to Mississippi causing us to be delayed by more than 6 hours and missing our event all together. Very disappointing. All because ONE crew member called in sick. United did grant us a $15 meal voucher, which was a small but appreciated concession that I wasn’t able to use because I ordered my lunch and paid for it before applying the concession, and the staff said it was too late to use it. Ugh! We also had a TWO delay coming back from Mississippi, but that was on American Airlines and it was due to weather, so not their fault. Anyway, not at all impressed with United’s handling of our flight and the HUGE disappointment of missing our important family event for our 90 year old mother. All that money and all that stress and emotions for nothing. Having to wait the hour to bring an employee from LAX seemed like something that should not have happened. Why don’t you have a local back-up? Santa Ana is not a little airport in a rural area.

Terrible. 2 hour delay. Sat on the tarmac. Missed my connecting flight. Had to ARGUE with Customer service to get a hotel and food. Terrible experience with my loyal carrier

Our seat tv didn’t work All the rest was perfect

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I liked the exit row seat. Hated the distance between gates in Houston.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

Paying $75 for my bag is disgusting. Got off ground late so I missed my connections. Kept us waiting for passengers in the cold. Will not use them again.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Pros: "Flight was relatively empty. Professional crew, comfortable seats"
Cons: "I think they skipped me with food service. Checking up on passengers who may have been sleeping would be nice. Headphones need to be purchased. Limited entertainment options."
Cons: "Communication about international COVID requirements before the day of departure."
Pros: "My seat cushion was out of alignment so not great. But I like the two side seat configuration."
Cons: "Boarding is a zoo. Board by row. It’s faster."
Pros: "Icelandair crew were very hospitable and accompodating"
Cons: "I have never sat in such a narrow seat. Literally could not put my hand down the side to pull out my seat belt. Two days later I still have sores from where the side of the seats hit my hips. Did not even provide complimentary peanuts."

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

I was at the airport on time , I checked in my luggage . The plane was delayed and the gate was change. The flight board did not give information . I did not get chance to fly. I am going to make a claim for it

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Trouble keeps changing the time and I was booked different flight without knowing it was bad experience

My concern is with Flight: 441 IAH-FRA I was very cramped in my seat and the person in front of me was reclined. I pulled my wallet out of my purse and when finished I did my best to cram it back into my purse. Our flight was very delayed and we were rebooked twice and lots of airport time. As I got off the flight I noticed that I had dropped my wallet( containing all my credit & debit bank cards + 240 US dollars & 240 Euros. I spoke to customer service & Lost &Found. I was denied access to look on the plane. Therefore I have been without money and given no help. Paula Bjork 503.545.6698

So far so good. I missed my flight because of the Lufthansa diversion. United helped me to figure out how to get accommodations from Lufthansa for my long layover. They help me book appropriate onward flight.

During the flight there was a medical emergency. We were diverted. Of course I'm thankful they cared for the health of that passenger, but they did a poor job of communicating with the rest of us passengers. In the end we arrived at our destination several hours late, with no direction of how to rebook missed connecting flights. It all worked out in the end. Those of us that needed accommodations were put up in a hotel by Lufthansa until we could make it to our final destination. But it was United Airlines Personnel who really helped us navigate the process.
