Great if not for the boarding by bus at Heathrow terminal 3. Medieval disappointing time-consuming and very hard on handicapped flyers. It was awful

All reviews good because...flight from BWI to London ,economy seats was miserable. I usually book 1,step up from economy but this would have added 1500 bucks 1 way. Bit the bullet and upgraded for retun flight, otherwise all ratings would have been rock bottom.

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.

This has been the worst experiencia I have had traveling overall. More than 3 delays, no one answering questions, no one at the AA counter. No one at customer service and after having to change transportation to airport and spend the night at a hotel paid by me, we were delayed inside of aircraft for more than 2 hours!!! Bad experience!!!

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

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.

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.

Excellent service and always our preferred choice of airline. Was surprised we had to pay for soft drinks though. Other wise great airline and customer service!

LHR is always kind of a challenge. British Airlines did a fine job. My tickets were the cheapest so I can’t complain.

Plane features were VERY old and outdated. footrest cushion was completely lose, plane felt dirty and a bit grimy. i was in business class. the lead flight attendant, Mary made a few announcements that didn't seem to put the cabin at ease (it didn't necessarily bother me, but could have bothered others). she said "the seat cushions aren't FDA approved, so you have to put them on after we take flight." everyone had already applied the seat cushions, and saying something isn't approved for flight may cause alarm. she also said at one point over the announcement ... "we can't get up because we are too afraid of the jet stream impacts" -- again, not helpful to those who are nervous fliers.

Carryon bag was judged to be too large even though it fit on first leg of flight and would fit on the airbus A320. Crew forced luggage to be checked. Electric battery powered razor was taken out of one luggage presumably by staff and never returned. Other luggage also had battery electric razor and battery electric toothbrush but was left alone. Now I have to buy another electric razor adding to the cost of this flight.

Extremely comfortable airplane, everything looked brand new, how lovely! My seat in Premium Economy was ever so comfortable, I did not suffer the usual backache I suffer when doing the transatlantic flight. It felt like seating in a reclining armchair. I loved the foot rest, did not need to use the portable device I usually carry along with me to replace one. I loved the spaciousness in front of me, and that there were only two seats (Instead of 3 in coach) in the window row, wow what a difference in comfort. Coach seats are always just a little narrow for my hips. The support of the cushions was great, firm and offered good support . It was easy to come out of my aisle seat, although I'm 70. The staff was courteous, both meals were delicious, very carefully prepared, and creative (fruit + cheese for the second meal, instead of the usual bread sandwich)

The plane was up-to-date, and the free wi-fi was very much appreciated! All of the ports functioned well, and the entertainment choices made the flight much more enjoyable. One of the flight attendants was unfriendly, but the flight was enjoyable overall.

3 hour delay before takeoff & another 30 minutes on the plane before taxi to runway

Rudest flight attendants ever, waited over 20 for light to be answered and it never was then tried to flag down an attendant who said someone else would come, just needed water to take some medicine Food bad

My entertainment unit kept locking up and had to be restarted multiple times. Also those commercials for Budapest and Ralph Laureen. Come on those were stuff only those who can afford the outrageous fees of first and business class would be interested in.. And the fact you have no military discount is not good either,

I was a Wheelchair Assist’ passenger on a London Heathrow to PHL flight yesterday. The process of getting me and my carry-on bag from the ticket counter to the gate was not good at all. It was the worst in my 5 years of experience using this service offered by American. The Philadelphia ‘Wheelchair Assist’ service was, and always has been Excellent! Not so at Heathrow. I was handed off to three different wheelchair drivers; had to sit in a very dingy holding area for 30 minutes while waiting for our gate change announcement; got crammed into a overloaded service vehicle to take me from the holding area to the gate ; was dumped at the end of the line of already-boarding passengers with my heavy carryon and no one helped me up the ramp way at the gate to board the plane. Overall it was a miserable experience!

Crew was nice, aircraft dated, entertainment same. Internet is expensive and terribly slow. Food pretty bad

Horrible experience. Food was ridiculous, insufficient, and not appetizing at all. They served sugary granola bar for breakfast. Furthermore, my bags were delayed and delivered damaged and American made it impossible to file for damages. Furthermore, the flights were delayed causing unnecessary stress given the connecting flights. It was awful experience, would never want to fly American.

great flights both ways on time both ways.staff(ladies) where great at check-in.

We travelled from London to Halifax. Customer service was excellent.fron the day we booked until arriving. The gate was only a short frombthe waiting area and walk Boarding was efficiently handled and plane took off on time. The service on the plane was very good. Fool an acceptable drandard Only downside was that the legroom was tight for anybody just over 6ft tall and am usually able to travel without difficulty. I will definitely fly with Air Canada again but next time pay for extr space.

Was disappointed when landing in Canada was made to wait for over 1 hour with several other parents and babies for our strollers . The expectation was that the gate checked strollers would be there when exiting aircraft. This was not the case we were told to walk to a point and wait for them . After being left there and not being updated we were met with very hostile and rude air canada staff . There where no apologies or understanding even though all the children where very uncomfortable and the parents very frustrated as you can imagine . Instead the air canada staff at the airport where very rude and made an already frustrating situation much worse instead of trying to assure the parents that that were making effort to fix the situation. One gentleman in particular was very rude to some parents telling them to move when they were simply seeking information. He made the other parents including myself feel very uncomfortable. He also told a gentleman he was capturing images of everyones boarding pass when this was untrue as he was only taking a photo of the gentleman pass which was strange.

It was good, seating was a little tight apart from that all was well.

I liked the flight but the check in was horrendous. I have booked with you before but not ever had to pay extra for luggage, it was not clear on booking, I didn't know there was different categories of economy that meant different allowances. So was alarmed when we had to pay a further £120 at the check-in at a point of not changing.

I wish they gave the earphones earlier rather than when we are already in flight.

Very nice staff members are very nice and friendly helpful

We were a little late pushing back ,but arrived a head of time.

The 787 Dreamliner that we flew on was relatively new and a nice aircraft. We flew on a 777 which was noticeably older and the seats were average” but the 787 was very nice, especially for the price. No window blinds anymore, instead high tech adjustable polychromatic glass!! Nice.

an absolute disaster and nightmare on air condition. IT WAS FREEZING!! everyone around us had hats, hoodies, gloves outdoor jackets on. that segment of the aircraft had a fault I assume...no amount of suggestion to turn down the air con helped. otherwise all good.

Horrible - for the first time in my life i was denied boarding an international flight because the name used on my ticket - Josh - was not exactly the same as my passport - Joshua. At no time during ticketing, online check-in, or at the airport flying from Boston to NY was i notified of a problem. It was only at boarding from NY to Costa Rica I was informed of the problem and by then it was too late. After missing the flight I was told by airport Jet Blue staff, including a supervisor, that it was my problem and they could not assist because i bought "the cheapest fare". i was hung up on twice by JetBlue customer service, including once by a supervisor. I blame Kayak and your awful partner ChatDeal for even allowing me to purchase an international ticket without verifying this - you effectively sold me a ticket i could not use. Shame on you and shame on ChatDeal for doing nothing to help me resolve the situation. What a scam.

The flight out was delayed from 3:40pm to 5pm and again to 8pm. We boarded after 5pm, had to disembark because they could not get the Engine started, then we switched gates and got a new plane and did not board until after 8pm.

Jetblue provided a very good service during the flight, the plane in a very good condition, the crew is professional, everything was on time. That's it!

There was a fowl odour coming from the lavatory the entire flight

The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!

Communication with the customer and stay is important. Staff off with a minor inconvenience but it worked out of course. Also this was a very old Mint Class plane. They snuck this one in on us. The updated aircraft are much better.

They put me on a chair in between two men, one overweight who was almost falling on top of me, and the other was even uncomfortable because I was half falling because of what the other was pushing me. I stayed with. my feet were swollen from fluid retention and from being unable to accommodate myself. it was very uncomfortable. I asked for help but they told me that the flight was full and they couldn't help me. I got off the plane almost unable to walk due to the inflammation. and then at FLL airport I asked for help because I couldn't go to my next flight, which was a connection.

Our actual Flight was great & smooth but it was delayed for 4 hours and Jetblue weren't able to accommodate us in the earlier flight. That was Awful. I lost work/clients because of this delay

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

We liked the flight, but not in JFK, not in Gatwick it is no lounge and this was surprising and disappointing. I think by now it is understandable that COVID will not go away and why it should not be business lounge?

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.
