Air France removed our luggage from the plane before it took off, seemingly intentionally, didn't notify us until after we reported it missing at SFO, and is giving us no updates on when, or whether, they will deliver it.

Air France removed our luggage from the plane before it took off, seemingly intentionally, didn't notify us until after we reported it missing at SFO, and is giving us no updates on when, or whether, they will deliver it.

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 :)

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

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.

They lost my baggage and I still have not got it back. Disgrace

Generally good. The crew is excellent. The food could be better.

We transited through Chad and what was supposed to be a 1hr 20 minutes transit time lasted over 4hrs. We didn't get regular updates until we complained. After a 10hr flight from Paris no form of refreshment given and finally arrived Abuja over 6hrs later and none of my bags came

Please serve no god if you must serve dog food

Flight was more then 3 hour late and I did not get my luggages

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

The crew and the flight were excellent, the food might be better!

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

I felt the overall quality of the plane and food service was less than that of their partner airlines, United. An example was wine was served in paper cups in premium economy class. There was no real silverware, napkins or a welcome kit other than a pillow and blanket.

my husband's monitor did not work. there was a visibly ill family in my husband's row.

we had to unexpectedly check a bag, the flight was late getting in

They blocked me from checking in online and they charged me lots of money

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Seats had no charging ports. Our plane was rerouted to Boston and we were landed on the tarmac with no food or water for 3 hours (illegal). We then waited in the airport for 3 hours while staff had no information regarding where our bags were or when we were going to get them.

Very poor communications during flight. Our flight was diverted with no communication. We waited for hours in the terminal for word on how we would get to Newark No chargers on the plane Won’t be flying them again

This is a terrible airline. Never again. We got diverted for weather and are sitting on the tarmac now for hours. No updates. No water. No food. This is insane.

Not have my bag forced to be checked when I had a carry on included on my ticket. Staff was very rude to me for asking why they were doing this. I was told there was no more room for carry ons but there was plenty of space in the overhead compartments

There were no delays. I almost lost my connection because of the new EES system

It was a game of hurry up and wait. As advised we arrived at the terminal e hours prior to boarding. We waited about 45 minutes before anyone showed up at the check-in terminal. When someone does arrive she rearranges the line and we think we are going to be checked in. Nope. She leaves and we wait another 15 min. before anyone else shows up. One person got behind her computer and about 15 min later started to check the first person in . Then one more person arrives spends 10-15 behind the desk and then she starts checking in someone. Two more staff arrive and another 10 min or so they are ready to begin checking in people. We have a 11:50 international flight and it is 9:45. And then on of the agents, closes her desk and leaves. And every leg of our flight was delayed; we waited at terminals, we waited to take off, we waited to deplane. After arriving in Porto within 10min of our connection schwduled to take off, we were told to go to the last bus. We waited on the bus (until all the other busses had left) and then we waited another 10 min or so for one of the ground controllers who wanted a ride with us but was busy with a woman who needed the handicap van. He did not help her to the van, but was standing with her and talking with hher. We were rushed through border control and told not to wait for the rest of our party only to get on the plane and then have to wait another 45 min before we were cleared for take off. The waits were not 10 or 20 minutes, they were 35-55 minute waits each time. Miraculously, we made it back only 2 1/2 hours later than we we were originally scheduled. Given the nonchalance and seaming disinterest from many of the staff, I was expecting that we would not get on until much later than that.

Departed late. Flight crew some of the most professional I have ever experienced. First time we’ve flown this airline

they canceled the flight. I was at the airport a total of 8 hours. had to fly out the next day. No compensation so far.

It’s a no frills airline. You have to be careful about booking carryon baggage in advance because they will charge you an exorbitant amount at the airport. Bring your own food onboard. I don’t think the drinks are cheaper in the terminal. Seats are okay. No entertainment, no WiFi and no charging of devices onboard.

Transavia has started an aggressive program to charge for cabin baggage. Particularly at Schiphol the checkin staff behave like money hungry nazis to charge you 43 euros for a laptop bag as carryon. They didn’t realize I can speak Dutch and I could hear them cheering about the incentives they get for charging extra fees. To make things even more ridiculous, you can’t even store the bag in the overhead compartment because it is so full. It’s such a turnoff and makes traveling on this terrible discount airline even more miserable. To add there are no charging points or inflight entertainment on the plane. The flight crew are polite and courteous.

Transavia scams you with baggage charges. I bought an extra bag to carry with me in the plane (27 EUR) via their website. When I came to the counter they told me the bag was not acceptable, even though I have taken this without problems in several other airlines. So they forced me to pay 65 EUR at the last minute to check-in my bag and let me board. When I asked for the money I had originally paid on their website(the 27 EUR), the personnel at the counter just told me it was not going to be returned because this was not the airline's fault. This is flat out stealing.

Horrible service, never flying with this airline again. They have 0 respect for the people flying and don’t respect their own rules.

My experience is very bad. The flight was canceled 2 hours before departure. I lost my hotel reservation and can't get it back.

Schiphol airport needs to get their stuff together. I had to wait one hour at the passport control for EU national ID members, not the international one that they were waiting for 4 hours, and the baggage claim had an other hour on top of delays. That is insane, trying to exit the airport, at this point just let me get my own bag from the luggage compartment.

No water or light snacks, unless you pay a lot of money for it. Zero leg space

Yeah, allow us to bring our carry-on luggage without charging more. I've never seen another airline do this, and decreases your chances of my using you again.

Booked priority boarding but all passengers boarded at the same.

Not Transavia item, but baggie claim took more than 30 min

On time departure; arrived early into Faro. Air Malta operating flight, crew friendly and efficient.

I didn't know that all connecting flights require online check-in two hours in advance, so I was fined 55 euros. This is a lesson learned.

There isn’t any entertainment. The food and drink was available for a price. I didn’t buy any.

It would be nice to have power to charge phone.

They boarded us but somehow did not manage to record us boarding, so rather than check if we were onboard they removed our bags from the aircraft. I got a call from Ryanair staff in Dublin when I landed in Madiera asking me where I was!!! When I said I was in Madiera I was told what had happened. Our bags were to be sent to Madiera the next day via Manchester, they didn’t arrive. They are now due to arrive two days before we leave. I don’t see myself using Ryanair again unless I am forced to and even then I may just refuse.

The flight arrived within 15 minutes of schedule. We hate the cattle-like boarding process seen often in Europe. After your boarding pass is checked by the airline staff, you wait standing up in an area with no seating for several minutes.

Great flight, departed only 10 mins behind schedule off the aircraft and through security in less than 15 minutes. Love flying from Cardiff so easy a quick from entrance to duty free in less than 10 minutes 😀

Well... Our flight departed with more than 3 hours delay from Beauvais.

Great flight very short… no food drink or tv but too quick to matter… I would recommend.

I haven't had a ok flight with Ryanair in so long!
