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.

Security was a mess at the Helsinki Airport. But I was delighted by the connecting flight waiting for us for JFK.

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

Everything was quite easy from boarding to landing - the staff was great and service was excellent too!

In-flight entertainment was. It working for the entire 12 hour flight! Unbelievable! At least provide free wi-fi so people could use their phones.

The flight was surprisingly good, especially given initial experience. BA app is horrible as is their customer service. Online check in was a horrendous experience and when I phoned their customer service number, the live agent with whom I spoke was rude and dismissive. She did helpfully inform me that their IT people were working on a known problem related to online checkin. However, once she delivered that information, she curtly ended the call before I could suggest that since BA was aware of this, it should be posted on the app and online. I grudgingly flew BA this time - have avoided them for years because of past similar serial bad experiences. While this flight was fine, I’ll return to avoiding them in the future given the hassle experienced and rude personnel.

Boarding was a shambles, with no proper line or queue and multiple groups joining at the same time. Overhead space was limited. Seat spacing (width) is not generous. My neighbour was invading my space, before he even spilt his drinks over me (twice!) as he struggled to contain his meal on the table. The main meal was very poor. Choice was simply chicken / turkey - the crew didn't know exactly which - or vegetarian. The chicken meal was really poor quality - uninspiring and tasteless; and very little offering of drinks. Half the crew were friendly, half really need to cheer up.

Food was pretty poor - bland, tasteless. Drinks offerings were very limited also.

My flight was on American Airlines, AA, through Finnair.. What I didn't like was that I couldn't get seat assigment until 48 hours in advance. I also was not given my AA Confirmation number. I called Finnair. They were very very helpful!

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 were fantastic friendly nice they came round and check we need anything else to eat or drink

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

Tai-City to Atlanta :Lots of legroom on the flight. No interaction from the staff at all on the plane. They only attended to the First Class passengers. There was no entertainment. Security I was body scanned even though I hadn't set off an alarm, my father-in-law in his 80s, was stopped and subjected to a through body search, told that they would have to place their hands in intimate places. There were several border guards present, and as we walked off we could hear the TWA officer talk about the procedure as if he was training. My father-in-law was a little upset about the whole process. A kind explanation that training was taking place would have been more acceptable, and it felt dehumanizing to him. Atlanta to London: Check in was difficult we had been unable to do this online for 2 of the family members on the same booking both in their mid to late-80s. No seats had been allocated for them and we were all travelling Premium Economy. After several phone calls to the booking agent and conversations with Delta staff at TriCites airport, we were told that seats would be allocated at the gate in Atlanta. When we arrived at Atlanta, and spoke to a member of the boarding staff at the gate, he was curt and repeated back exactly what we had just told him, that only one of us was checked in. I explained that we had been unable to check-in online for the 2 family members (I had tried twice). He again repeated back that we needed to check-in. As we were in transit, I was at a loss at what he wanted us to do, but he kept repeating that we needed to do this. I asked where we should do this. No answer. In fact all he did throughout was look at his screen. He told us that there were no seats in Premium Economy, and that he could offer my parents-in-law 'two seats at the back'. I asked if he meant at the back of Premium Economy, and he replied, 'No, at the back of the plane'. At this point, myself and my father-in-law pointed out that they had paid for Premium Economy tickets and expected seats there. He never took his eyes off the screen once. Then he hit a button and it printed out two boarding passes for my parents-in-law. The seats were directly across from my seat. He had gone from saying there were no seats to somehow finding two together. No explanation, no eye contact, nothing. The flight: As we boarded, our first introduction to the flight was the stewardess at the entrance addressing a passenger with an annoyed and loud voice about a bag that belonged to them. That was not promising. The seats were good, and so were all the accessories. The food, etc.: we had flown with Virgin on our outward journey and I could not fault it. The service and food was excellent, the stewards very helpful, offering additional drinks and snacks. The toilets were more accessible than Delta, which were in the economy area and were told in no uncertain terms that we should not use the First Class toilets, even though they were much closer to our section of the plane. We had a menu for both flights, yet when I asked for the chicken dish on Delta, I was told that there was none left and that there was another chicken dish with mashed potatoes and that 'it was fine'. This was almost pushed on me before I could answer. I was sitting 3 rows from the front of the section, so I was surprised that they had already run out. I repeated that I would like the chicken dish on the menu, and asked whether she would be able to get one from her colleague who was serving in the other aisle. The stewardess replied 'No, that's not how it works!' It always has on previous flights, so I was a bit confused. I accepted that I would have to opt for the pasta option (no choice), but was a little perturbed by her response. Minutes later she returns and hands me the chicken dish I had originally asked for. I had already started eating the other one, but was told curtly that I could have both. This was the same stewardess who was shouting at a passenger as we boarded the plane. The food was very poor in the end, nowhere near as good as Virgin's. Unlike Virgin, there was no starter, no bread roll, just a main and a brownie served in a cardboard container. Virgin had provided real china and glass. Unlike Virgin, they did not return to ask if we wanted more drinks, and there was no tea or coffee served after the meal. The breakfast that was served later was equally poor and inedible, apart from the fruit. At the time, the stewardess, a different one, completely walked past my mother-in-law and did not offer her a hot drink. Both my parents-in-law are in their mid to late 80s, they have been world travellers in their time and had decided that this would be the last flight that they ever take. They have health problems, including memory issues. I feel that overall the journey back to London was pretty unpleasant for them especially, and that they were treated badly, especially by the ground staff. We have lived on two continents and are used to long haul flights, and I have to say that this is up there in the worst flight category. Bearing in mind that we had paid extra money expecting comfort and additional attention, it was extremely disappointing. I would fly Virgin again, but never Delta. The two flights were incomparable.

Needed a 6 hour lay over in Atlanta. How can this be avoided ?

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

Staff was friendly. Food was so-so. The economy seats are probably some of the most uncomfortable I’ve ever sat in. The headrest kept falling down which has happened multiple times before on Virgin.

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

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Excellent as always. Had issues checking-in online. Please fix.

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

It was fine. Everything ran on time, crew was great.

Staff friendly and app worked really well. Modest delays were frustrating

They rerouted flight to LAX. Offered nothing but a 5 hr drive to SBP. No compensation. No regards to our healthy and safety.

Both flights were fine. I wish there was a little more legroom, but we got to where we needed to be on time, the crew did their job, and that’s really all that matters. We’ll fly United again.

I wrote about this leg of my itinerary in a previous part of this review

United flight from Frankfurt to Istanbul is on Lufthanza and United could neither provide a boarding pass or Lufthanza code to get a boarding pass. Very poor connection ability in Frankfurt and much frustration with the connection.

Great flight. Left on time, not very crowded. Quiet and the right temperature.

No eye patches , socks given out for overnight flight! The snack on the short haul was a cube of chocolate! The seat was uncomfortable for a long haul - not enough cushioning!

I paid a lot of money for seat selection and was miserable for flight duration

Lufthansa lost our luggage. After a lot of chasing on our part we got it back. The main problem is that there was no office in Bogota to help us outside of flighttimes. The customer service phone lines had no data on our luggage. I think Lufthansa need to invest in managing communications over lost luggage or this will end with everyone taking more luggage out of hold.

Very good service. One of my journey was by bus. But they advised by plane. Wrong information

No entertainment, no food or beverage included… Price like Lufthansa, “comfort and service” from Eurowings.

Plane was late taking off. Baggage was delayed over 2 hrs.

The flight attendants were just awesome. Friendly, professional, timely, etc.

I sat in the last row of seats. On an 8 hour flight they allowed folks to stand and talk and drink in the back area near the toilets the whole time. They were at times loud and in the way. It was a little annoying. The crew on this trip were pretty mediocre and the plane was littered with trash when we disembarked.

Boarding process needs to be improved. Business class passengers were told to stand in the economy line and vice versa.

I travelled on biz class and f there is no water in the toilette to wash my hands I would expect to have this indicated somehow and not just finding out when I'm there expecting to be able to wash my hands and teeth. Also this is in general that it is always so rushy at the end of these kind of long flights. It is like we are sitting there for 9 hours and the last 1.5 hours just feels like I have time for nothing. Because food comes and at the same time we are close to destination everyone tries to pack their stuff and go to toilette and eat and everything :))) not that like I would know a good solution here I just wanted to raise this :)

Emergency row seat less comfortable than promoted. Restricted by emergency life raft storage.

Better communication to those connecting flights and have a customer care desk at the airports

The entertainment system in our row was not working. That makes for a VERY long flight!!

Pre flight food options were not working and made the flight not enjoyable. Post experiences of British airways have been positive, but this is enough to stop me using British airways again

Flight cancelled and i was rebooked on delta. Delta business class is not the same as British

Boarding could be smoother. But the flight crew was excellence. Very professional, friendly and helpful.

Everything was fine except my screen wasn’t working and I was unable to watch any movies or TV. Staff tried 3 times to reboot it, without success.
