I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

I Love Delta but one of the flight crew training in courtesy snd hospitality.

The temperature on the flight was unbearably hot and they were unable to serve waters and did t make any adjustments. This impacted us both when leaving, we pushed away from the gate but didn’t taxi for takeoff for awhile then arrived ‘early’ yet were stuck in the plane for longer than we should have been.

My seats are comfortable because I choose to fly in the exit rows and this time upgraded to first class with minimum sky miles. Otherwise, I would not be happy in regular seats or even middle comfort seats. Onboarding on the return flight from Nashville to Atlanta was hot and very uncomfortable for over 30 minutes due to extreme hot weather. However, Delta should provide some other air flow option as it was almost unbearable until 10 minutes after take-off. First class seats should be equipped with cup holders. Currently, the middle console is used and is flat and prone to spilling drinks.

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

The CRJ-900 was clean but the overhead air vents were broken in our First Class row, making the cabin very hot until about 30 mins into the flight. The flight attendants were both extremely apologetic and accommodating though so that is why I rated the flight as very good. They checked on us many times and truly showed they cared. The snacks for an hour and a half flight could be better. Would be nice if there was a small plated meal over convenient store snacks. WiFi also was not working. And it would be nice if Delta had adjustable headrests on these planes.

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

My easiest trip ever. Flights left on time, and came in a few minutes early. The flights weren’t full so it was very comfortable. Thank you United

The united employees at the gate treated me very rudely and called me nefarious

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

Internet is much improved, which is very important to me a s a business traveler. The off boarding of the plane was fantastic. Very quick and very orderly. We had to check our carry-ons before we got on the plane and they were retrieved and available to us very quickly. We left on time and arrived early. All very good things

The flight was overbooked. And the gate agent basically said that the flight will not leave unless two people came forward to give up their seats. Offered money. Raised the $$ too. But we were there for a while and flight was delayed. When passengers approached the gate agent asking what would happen if no one volunteered- the answer was flight would be cancelled! Ridiculous! It’s American’s fault for overbooking. The service level is going from Bad to worse it seems.

My wife has a scooter and they where supposed to send from departure to destination and had it go to connecting flight,not good.Nobody has knowledge of the scooters or the battery's.

Not to have gotten delayed by 2+ hours for the fourth straight American flight. They're the worst.

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

This was a horrible American Airlines experience, and it discourages me from flying with them again. It may have stemmed from a mechanical delay, but it appeared that the team was unprepared to respond to the delay. After boarding, we waited an hour before finally taking off. After landing at our destination, we waited an additional hour on the tarmac waiting for a gate (at 8:00pm) to be assigned and cleared. The flight crew did their best, but they were clearly tired and also ready to be done for the day. Because of the delay, I missed a connecting flight. It was a very poor experience.

Fantastic! If it had not been for a check-in agent in Knoxville I may have not gotten my passes on British Airways. I couldn’t check-in online because British Airways had messed us the info on my tickets to London & Inverness. AA’s was great! British Airways was a continuous series of delays and frustrations.

Wheelchair was waiting for me,changed to a better seat which was great as it's hard for me to walk

My premium economy experience did not live up to my minimum expectations. I've taken this flight twice in the last three weeks, and each experience was the same. The premium economy seat was worn and extremely difficult to recline. It took two people to return it to its takeoff and landing position. The food was OK, but for the premium that a premium economy seat cost, I expect a satisfying meal. Years ago, I looked forward to the experience of flying transatlantic on Lufthansa (I especially enjoy the hot towel before the meal), but this is not been my experience recently. I'm not going to use Lufthansa again.

If was mostly my own fault. I booked and paid for a window seat. That was a mistake for a long flight. It was hard to get up and use the bathroom. The entertainment system seemed primitive for a modern aircraft.

It was a safe and smooth flight. Members of the crew at the second level, business could have been more polite and engaging.

Our seats were not together - one on upstairs business class, the other nicer downstairs business class. Terrible!! A very nice agent worked hard with other passengers & got us upstairs together. Not ideal experience. Check in agent should have caught that! Asked about upgrade to first class for additional $2500 each. Refused upgrade saying we upgraded once already. We booked on business class to begin with so we’re NOT happy!!

Old planes and rude crew. They need a make over and better staff training. Even business class crew was rude and the hospitality was non existent.

They left a little late, contributing to our missed flight.

Great. Only issue…the cabin was kept as warm as a sauna.

United did a good job of communicating before the flight, but a simple notice about the expected time for the completion of repairs to the broken navigation services (which closed the airport for the day) would’ve helped to clarify our expectations. With so many cancelled flights on the 21st of September, a little certainty about our own departure would’ve helped. Because of the disruption, the plane was quite empty, and at 6‘5“ I was able to steal a little extra legroom from the empty adjacent seat. However, I am still waiting for the day when I can sit in a standard economy seat and simply straighten my legs. Cabin crew were amazing. Great attitude, and moments of fun with passengers.

Lufthansa was great. Crew on board excellent. Frankfort passport control horrible it took about two hours to get through. After waiting in line for hours there was a discussion with the passenger in front of me that was taking forever. The couple behind me had a connecting flight to Turkey in 30 minutes and asked border control officer of her situation and the control officer told the couple in a nasty tone if you don’t like it you can go to another line which would have surely made her miss the flight. Border patrol officers were not helpful. Finally made it through I had to exit and reentry for security check for my connecting flight which Lufthansa changed gates and I had to run to get to A60. Which it seemed 2 kilometers to get to but I made it. If i fid not have 2.5 hrs layover i would have missed my connecting flight to Milan. Not sure if I will fly through Frankfort in the future.

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.

It was my experience w Kayak that was negative. I’m never using kayak again

Flight was delayed 4 hours, gate change was a big trek the opposite direction, gate agent indicated a lack of faith that we would actually fly.

I washed attendant for assistance and she never got back to me. I asked her a second time and she said she would check. She never did. The flight was over an hour late taking off No food service was offered despite over 4 hours on the flight

I chose seating based on me being 6’3 and they changed planes I guess bc I got 2 random Seats that were middle and window and vert cramped and uncomfortable for a long flight….should have been able to get same seating just different aisle maybe especially since we picked them and weren’t random

Flight was fine. We were in business class, so lie-flat seats were appreciated. Kids were in premium and said it was nice. Flight was delayed by 3 hours, so we missed everything we had planned in London the first day.

Seat pitch is not enough to eat comfortably. When seat in front is reclined, your screen comes closer to your face. Ryanair seats are actually more comfortable.

The crew were professional and friendly. It was the most uncomfortable international flight I've ever flown. Crammed in passengers. No overhead space to put my bag. No leg room and unable to recline seat due to seats too close together so it upset passenger behind me! Upgrade price to get 2 inches of more space unreasonable.

Pilots seemed fine but one stewardess seemed crabby, but it was tolerable just didn't seem to be projecting a service attitude. I understand we all have those days. Return flight on 8/8/24 noticeable better / normal.

It said that there was wifi. During the flight there was no wifi and while waiting at the gate the phone services already got cut off so I wasn’t able to say I am taxiing from the gate to my husband. This left me with an uncomfortable feeling. So I was waiting on the WiFi connection during flight and that never happened.
