Airline reviews

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

The flight was excellent, I recommend people to fly with Delta

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

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 !

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

T hey did a great job. Flight was on time .

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

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.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

Touchscreens do not work. WiFi did not work. Food is possibly the worst on any European airline. Drinks came by only four times on a cross-Atlantic. The plane was two hours late because—it was announced—Lufthansa didn't have enough large aircraft in their fleet to accommodate an on-time flight.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Coach seats are too tight. Seem designed for small people. Food different but OK. Staff helpful.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.
