I love Air France. This was another great experience despite a slight delay in the departure. The time was made up on flight. I would take AirFrance again when traveling to the far East. Merci beaucoup.

I love Air France. This was another great experience despite a slight delay in the departure. The time was made up on flight. I would take AirFrance again when traveling to the far East. Merci beaucoup.

Everything is good except the seats are tightened no rooms for the legs,

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

They lost my bag and I still have not received it

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Not consistent with the food quality (I mean taste not freshness)

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Entertainment system is okay, flight attendants were ok. Leg space very narrow, I couldn’t get what I wanted to eat, dinner nor breakfast.

Excellent experience with business class area. Staff was attentive and food was amazing. Only one bathroom for business class which was logistically difficult for the staff while preparing meals. Need to offer fluids with meals. I did not get enough water to drink. But overall I rate it 5 star.

On time, great food, good drink selection! Only down was alcohol-free lounge. Lufthansa had a much better offering!

Be honest of what you sell: This was sold as Business Class on all three legs, while the JetBlue plane didn't even have business class seats, and wanted $164 for extra legroom seats.

Seat assignments for family traveling with 2 children. Loud crowd during sleep time

It was crowded… the bathrooms dirty and smelly. The seats have been made even smaller.

delayed to take off from detroit by 3 hours lost baggage in istanbul and now in venice without baggage

Seats were very tight with poor legroom - and I am average height. During the 12 hour flight, tiny paper cups of drinks we're only offered during the super and breakfast services, with the crew nowhere to be seen in between. One of the bathrooms was out of order, leading to long lines waiting to use the remaining two available to the economy class passengers.

short flight but we still got a very nice lunch and the crew did an excellent job in taking care of us

For that price on Business class, I expected to have the pod seats. These were configured as 2/3/2 and my seat mate talked half the flight with a friend across the isle, loudly. Very uncouth.

Very good in business class but not so good in economy.

I need an upgrade to business class but they ask for bidding. Never mind...

Business class website is horrible I couldn’t even check in online never happened me before any other website

Long wait transit service wasn’t good also I couldn’t check in online never happened me before other websites

Very poor service, will never travel through saudia airline also worst experience at jeddah airport, all the people act like very racist even we belong from a same religion but they don't have any humanity. Very big language barrier no one speak proper English so they don't understand us very poor service. I was traveling with family and with infant they give us very hard time. No one like to answer a question and there attitude is extremely no welcoming. Not recommended specifically jeddah airport and their services and staff. Will never take layover or any flight through jeddah. Thank you

Horrible, by all accounts. Delays, lack of communication, just horrible.

They destroyed my baby’s stroller and the seats was broken

I had the worst experience I’ve ever had with any type of airline,they destroyed my baby’s baby stroller,that cost more than 2000$,the seats in a 13 hour flight was broken,so I definitely not recommend that airline for other people

The flight was delayed which cost me to missed my connection flight.

The planes are very cold. The AC is too much.

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

I payed for extra leg room but in last moment my seating place was changed and i got standard one seat. Staff was not able to do anything , so was very disappointed because of this.

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

Very disappointed to not have lounge access The shorter flight seats were uncomfortable

1 hour delay meant missed my connecting flight and 1st day of holiday

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Good one but just notice that you have to ask several time to get water or coffee .

Early arrival. Good boarding. Deplaning this flight is very slow both coming and going. Baggage arrived quickly for Pearson

Dirty and smelly lavatory and toilets in Wamos Air operated flights

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

This is my second time within two weeks using them. I have bad experience with their Internet. They charge me $35 for Internet worked only for 15 minutes and then disconnected and they don’t even give me a credit or refund my money or give me a voucher about the food. It’s very bad test. There is no test actually and barely cooked still raw.

I love everything but the hotel the hotel was very smelly and the people were so rude the food was so cold and very disgusting. The manager was also so rude

They cancelled the flight while we were at the gate. Then they rebooked me for the next day but then that was missed because I now have a connection and the first flight took too long to get to the airport. Right now sitting in the hotel until the next flight. Worst trip

We traveled on Business Class called Crown class, and the experience was outstanding. Separate check-in area. Private separate entrance to Passport Control and Security. Excellent lounge not too far from gate. Fast seamless boarding. Very attentive flight attendance. Excellent service in board.

Excellent There was no hot beverages in the last hour

POOR. The gate changed 5 times. The plane was late. The waiting crew and the desk staff were gossiping and chatting amongst themselves about the maintenance and plane issues. No water service on the plane after the long delay. Even after I asked for a water. I was in seat 1A. Single crew member we saw sat in the seat the whole flight on his phone. After a stressful boarding process and delay- it was REALLY disappointing.

I was most disappointed with the flight crew in business class. They were not attentive at all. Everything I needed, I had to ask for. They did not offer refills, did not ask how the meal was, did not offer anything else when I didnt like the drink that was poorly made. When I asked for snacks, they told me to go to the front and look at what was set out. This was the worst RJ business class crew I have ever encountered. They made me feel like I was a bother - even for a simple water. No smiles. No thank you. No my pleasure. These are the reasons you fly business class. At least the crew can smile and act like they are happy to be there. For 14+ hours, I felt like an inconvenience. Poor review.

Crew was apathetic, in seat hardware was old and barely functional, WiFi (which I paid for) didn’t work for half the flight (I was refunded). They gave 2 meals on a 13 hr flight, whereas Etihad gave 3.

Awful, they made us rebook a ticket (out of our own pocket) because of a missed connection.

We were waiting at the counter for over an hour. Then they moved all employees to the inside. At that time it was about one hour and 15 minutes to the flight. They left us without help. Flight departed 20 minutes earlier than published. I guess they sold our 3 seats to other customers and bumped us. We did not fly. No customer service no help no answer.....
