Be on time. No issues with weather etc. entirely on airline.

Two of the flight attendants were cranky and seemed like they didn’t want to be there. Not up to normal Delta standards. And our bags didn’t make flight to Italy from Amsterdam resulting in having to make a trip back to airport which cost me 75 euros.

Delta staff was exceptionally helpful and considerate. However, the first two of three flight legs were delayed making connections tentative and stressful.

This wasn't my experience with Delta. It was just the Pegasus flight. Seats were very hard. Staff was kinda rough. Not very nice. Charged me for snacks. For a 4 hour flight I would've expected more.

I had a flight cancel and had it rerouted. When the rerouted they put me at a window seat instead of an isle. It was hard sitting by the window because the couple with masks on were making out. I get motion sickness which is why I need to have the isle seat.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

I just can’t understand why are you sell to many tickets ???? We had to wait 2 hours before 13 people from our flight take money and go to next day flight!

The only real hiccups in the flight were things beyond Delta’s control - turbulence which delayed food service and a departure delay caused by some VIP plane which stopped all departures and landings for 30 minutes - and was never explained to us by the crew. Otherwise good flight. I would fly Delta again.

The plane was frigid, and leaked water from the ceiling all over me and my seat.

Connection times always good online, but not in reality when first leg is delayed (2 out of 2 times this trip).

When booking, the connection times seem fine. But in reality, my two connections were cut short by the first leg being delayed due to issues at the destination (too much traffic going into SFO, ORD) and it became extremely stressful.

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

Even through the flight was delayed due to storms near IAH The flight was great! The crew was so hospitable and professional

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

The attendant were friendly. I suggest you have a medical attendant on board every flight so that in case someone is sick , he/she will help them.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

When our flight was canceled and rebooked, my husband's meal request was not transfered. As a result, there was nothing he could eat for dinner and breakfast on the new flight, save a side salad and roll.

Very bad 3 times change the gate and too much delay...

Everything could have been better. What needed to be wrong with United went wrong

The flight from Dulles to Munich was just okay. The seats were comfortable and extra foot room was noticeable in comfort plus. Disappointed in the booking in so much I requested an aisle seat and then was assigned a middle seat. The food was inedible. Movie choices were moderate. I usually fly Delta, but this WA flight was cheaper. Next time, I'll happily pay the extra to fly Delta.

Connection time and departure time were both changed to cause undue stree on older people who cant run through an airport

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Terrible. Missed our flight to Newark as well as our flight to London. Complete disaster

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

Plane was very delayed. US agents unhelpful in connection flt and in seating. No real info given on delay.

Good flight, no turbulence. I felt safe and comfortable which is really important when I am just a passenger.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

I paid for a very expensive Business Class seat to and from Cairo Egypt from Charleston SC. There was partnership from states to London using American Airlines. That leg was amazing. The British Airlines leg was a joke. They used the standard no leg room 3 by 3 seats. A tray was put on the middle seat. The trip was 5 hours, from London to Cairo, thus my BC purchase. There was no screen proving tv/movie options, only a small device plug. The fold down tray and the bag of peanuts were typical of normal short run flying. The one toilet was located in the galley. We all got to know each other well. This was my first and last trip with British Airlines. I now understand why they would NEVER give me a seat chart so that I could make a selection.prior to departure. It honestly would not have made a difference, there were less than 50% of occupied seats. Apparently everyone got the memo but me. I have never felt so cheated as with that trip, got to so another going back to London, yeah. I will be sending a letter to customer service and asking for a refund. I will be photos comparing the two BC legs. OH, one more thing. The FC ticket holders got bulkhead and exit row seats. I know they had to be thrilled

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

The on flight entertainment system touch screen system and the USB charger did not work on multiple seats on least 4 seats an in different rows. The attendant tried to reset the system but was un successful. I couldn't change my phone to get my ticket for my next flight. This was an international flight I changed seats and the problem was the same. the flight attendant offered his power bank

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

Once again I purchase a business class ticket and the seat is exactly the same as cattle class, the only difference being is that BA install a janky table over the middle seat so there is somewhere to place your complimentary drink, the tray table is just big enough for the small tray, so if you are not concerned about getting fed and watered on the plane or getting access to the BA lounge I would save your money and fly cattle, PS the cabin crew were exceptional in every way, shame about the equipment

Flight was delayed hours which caused us to miss our connection and lose a day of vacation. CHS staff was great.

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

A Perfect 2.5 hr flight. No amenities, but we did not expect any.
