I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

My experience was good overall, the quality of the food really decreased! There used to be a choice between meat and fish now it’s between chicken and pasta! In the choices of entertainment meditation has been added which is very good. Soft chair workout to improve blood circulation and avoid phlebitis should be added.

I wish that the meal included a vegetable or even a salad instead of couscous! Why serve chicken with rice AND couscous? Service was good overall though a bit lacking in friendliness. Usually on air france I've been offered a glass of champagne before dinner, wine with dinner, and a digestif after dinner. We were only offered wine this time!

My wife and I had a row to ourselves after moving seats. There were no TVs and you had to buy food. So we did nothing but had a quick nap. Flight was fine.

The male attended that served are section was a snob. He did not answer my call light when my wine spilled all over the floor. I did not push it again or drew his attention to it. He just ignored the call light when he came to give us our meal, serving the people behind us first. I did not push it again or drew his attention to it to see his reaction. It was so obvious that he was ignoring us. We were in premium economy!

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.

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

The flight was ok but chargers did not work and the speakers in the back of the cabin did not either. But I am writing because the crew was really, really rude and not only rude but had the curtains always closed, forgot to clear our trays, the bathrooms were filthy and trash was building out, and one of the attendants even had her EARBUDS on while in the cabin. From movement it seemed like she was listening to music, so not even the safety aspect was there. My neighbor s English is not good and they were very dismissive of her. when we deplaned the crew in the back was just chatting with one another and the first class attendant was briefly and said goodnight. It is nice that a crew gets along so well, but they did not take care of passengers at all. They rushed through all the services and otherwise did not go through the cabin to offer water or anything else. i had the feeling of being unwelcome at a party. I am not a grumpy traveller but I thought you really needed to know. Thank you, Carin

Food was terrible. They ran out of options and gave me a bland undercooked pasta and veggies. Only middle seat was available to select although I paid extra. Baggage delayed at destination. Flight attendants not really helpful.

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

Crew was great. But my flight was late arriving and as a result, I missed my connecting flight to Richmond. I had to catch a later flight. On a positive note, the attendants at the counter were extremely helpful in booking my later flight. They book my on the next flight to Richmond.

If the plain wait for the passenger it should wait for the baggage!!

The plane (Mitsubishi CRJ) felt old, creaking and not very new. The crew was okay. Hot water provision was broken so hot beverages could't be served.

One one boarding scanner was working to scan 400+ passengers to an Airbus 380. Food in premium economy was mediocre.

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

There was a slight delay. Otherwise, everything else was satisfactory.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The plane was known to be late in advance of takeoff. My guess is that it was known to be late at 11am or 5 hours before scheduled takeoff time. We were late to leave and with a wheelchair and the a cart, we only made it to gate. We raced! Inside plane, all was great

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.

I liked the comfort of the seats, very attentive crew, and the meals were excellent.
