Loyal Delta traveler, but last nights flight was a train wreck. Seated in 1B after multiple delays. Then we couldn’t takeoff because of an issue with the passenger that was ‘not in compliance’ and had to deplane along with the threat if they did not deplane, all the passengers would be required to do so. Finally they were escorted off, but the experience threw off the crew. Disruptive for everyone. Service was a mess, televisions didn’t work, bathroom door kept swinging open during the entire flight whenever empty …

Late flight caused a missed connection, had to be put on a later international flight without my requested vegan meal.

Older plane and it came with Fleas and flea bites!

Flight was canceled so it was not a great experience. Boarded, then deboarded. Delayed, boarded a new plane then deboarded the 2nd plane and flight was canceled. Then booked a fight to Rome and took a train to Venice the next day. Lost an entire day +

All good on Delta's part. Passengers could be a little more courteous to each other.

Half the bathrooms assigned to economy were out of action

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

Everything went well with the flight. But one of the flight attendants had on inappropriate pants. She had on an old worn out pair of sweat pants. The back seam was unrivaled and should not have been worn for work. If I had not seen her in the airport with the standard type of luggage, I certainly would not have thought she was working for Delta. Not a good look at all for representation.

Great!! I haven’t had a bad experience with them.

Pot and crew did a tremendous job landing in Savannah in the middle of the tropical storm. !!

It’s a service to take you from one point to another. No frills. You want it, you take it. It’s upon you to bring food, reading material, games to play, movies to watch, etc. The wifi onboard never works - so you cannot even listen to any podcasts, music, or get updated news feeds. The toilet is a mess, and a four flight does not need any hygienic interventions when people either splatter their pee all over the seats or on the floor. It’s a monopolized service and so smile and bear it.

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

Horrible! I paid for a straight flight from Chicago to London. A week before trip it changed and now I had a connecting flight. Our flight was delayed an hour and a half because our flight crew was still flying in from CA. Forty passengers ran from one plane to the next. The next United Airlines flight was delayed two to three hours because of mechanical difficulties. They had to ready another plane which took time. I missed my scheduled excursion in London. 😢

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

Lufthansa placed a 300 lb passenger in the aisle seat and I was stuck in the middle leaning sideways with no arm rest or ability to sit up straight and fully use my seat (due to encroachment-the seats are very narrow) the entire flight.

Everything could’ve been better. The boarding process was a little tedious, and then they put me in a seat with the window did not open, which gave me a very uncomfortable feeling considering I had told them that. The entertainment system didn’t work for quite some time and because I had to heavily medicate myself to not have a panic attack I missed dinner and barely ate anything on the flight. Not to mention the religious man next to me, praying mostly and humming the whole flight.

UK Based crew was great. Very friendly and quick. The seats are just too tight and not comfortable. The plane appeared quite old. Food is better on other non-USA based airlines.

Terrible! After boarding we were stuck on the plane for 3 hours with no air circulation during a heat wave.

They crew was very lovely, took off on time, arrived according to schedule. Was able to make my connection.

Extreme weather delays. Missed my flight to France and I ended up leaving the plane.

I arrived to LaGuardia Airport 50 minutes prior to my 6am flight but was told that I was too late and would have to flight standby to Dallas in order reach my final destination of Jackson, MS. Hundreds of people were in my situation but the agents chalked this up to being normal for any day. Had my been able to board my original flight I would have arrived at my destination by 10:30am. I didn’t arrive until 7:30pm which included a 30 minute wait on the tarmac. Strangely my luggage arrived at my final destination at 12:30pm of the same travel day. This was by far the worst travel experience I’ve ever had.

They were not helpful in letting my baby and I rebook a flight early in the day when it was clear we were going to miss my connection (we did). The seats are much smaller than I remember. I did not get the option to board early with my toddler. I was flying solo with her and that would have been a big help.

not enough crew for business class and not great service as a result. underwhelmed overall

The offered WiFi on AA isn't worth wasting time or effort on. If you manage to connect it's incredibly slow.

The crew was very helpful and the aircraft was clean. More attentiveness to us in business class.

It was a tiny plane. There was a very heavy, very sweaty man in my seat. When he got up, sweat was dripping down the back of f the seat from the headrest. I couldn’t lean back the whole flight. It was very hot in the plane until we took off. Then as we flew low hoping to land, but were delayed for over 30 minutes, the plane got very hot again. On takeoff, the pilot started accelerating hard around the corner, something I’ve never experienced in a plane. Landing was fairly rough as well and we had to brake hard.

Crew never smiled, never helped , told me to make my own bed ( in Upper class), never offered a drink

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Missed this flight due to the first AA flight delay

The seats were very uncomfortable. The food was terrible. They only came around with the drink cart for dinner and breakfast. What if we needed water or something? I had to take my pills in the morning with a pop I bought from the airport. Absolutely ridiculous! Will never be flying Air Canada again after this trip!

Could not switch flights. No help from check in Four people doing nothing. Two hour wait on telephone but no other flights available. Overall experience sucked.

First leg on journey was great, plane amenities, crew and arrival time

The economy seats did not have sufficient leg room, but it is what it is. I normally do premium economy, but my ticket was a present.

They changed the seats that we paid for 3 times after we booked and paid for them causing me to have to call them. We had a connecting flight from my through Montreal and on to Calgary. It was raining in Montreal and they left our luggage outside in the rain. Water seeped into the luggage soaking our clothes. This was our first and last time traveling on air Canada. Use another reputable carrier, not them

Internet wouldn’t work even after I paid for the package. That was my only real complaint, otherwise excellent.

My flight ✈️ was delayed by 12 hours causing a disruption to my day

Flight canceled last minute. Chaos. People got told different stories. They would not rebook me at the counter, then we had to walk to the other end of the concourse to use the phones. Meanwhile, a family 10min later was able to rebook at the counter while at the same time, customer service told me there were no flights left. Took over 2 hours to get a rebooking on Scandinavian air the next day. Ended up getting charged $300 for 4 checked bags by air Canada and then getting charged for checked bags the next day. Worst of all. At 11pm,the night of the canceled flight, all but 2 customer service agents at the check I'm counters left, leaving more than 50 people still in line trying to figure out what to do.

The flight attendant when departing JFK was mean and rude to passengers boarding

First time flying Air Canada staff was helpful from entering Newark Airport thru boarding and baggage and on flight. Entertainment was good on flight Helpful on landing as well

Wow I fly a lot and BA are probably the best major airline to fly with

First leg delay, rescheduled second leg without our approval, cancelled rescheduled second leg, rescheduled cancelled leg to three days later...

Flight was 2.5 hours late. Could not have made the connection in London, but later found out it had been cancelled. Getting reticketed in London for the flight to Geneva went well after I figured out what to do.

So very uncomfortable! The seats were dreadful and the space in a middle seat was too small. I don’t know what I would have done if I were 6 ft. Tall. I feel like the airline deliberately made the seats so close together for the purpose of selling the more expensive seats. Economy is on thing, but there should be a minimum standard of care. The meals were taste free and soggy. I can choose not to eat the meal, but I was trapped in the seat- so overall the lack of seat comfort is the biggest issue on such a long flight. I have flown overseas British airways, although about 10 years ago, and it was a fine experience quite unlike this flight.

Nothing. BA flight was late. Missed connection and lost luggage. A disaster.

My long haul flight had all the room and comfort of a budget short haul Is this BA’s standard now? Like every non descript budget airline

The crew was attentive. The food was tasty for the most part. However, some ingredients indicate heavily processed ingredients. Also, lots of disposable plastic items, plus packaging doesn't seem to be recycled.

It was good but my seat was terrible for a long trip, too small

Baggage arrived 3 days later. Will not fly with BA again.

It took an hour and a half for luggage to be dlivered in London
