Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

Very unprofessional treatment of customers - boardring on being unethical. Only cares about money and not the customer. If you use the swiss brand, you should deserve it - now swiss air doesn't deserve the swiss brand.

The flight itself was fine, but due to a snow delay my connection to Lisbon was delayed by six hours. Despite this, Swiss Air still managed to lose my luggage. Not acceptable. Someone else on the flight also lost their luggage.

Best international flight I have had in a while! Far superior accommodation, services, food and general experience compared to U.S. airline companies.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

The meal was wonderful and strawberry ice cream was a plus.

The flight was generally good but was delayed departure meant a very late arrival for a connecting flight.

Delayed 30 mins Forced to check in my carry on luggage

No fault of the crew, but the the rear lavatories were closed the entire flight. The front lavatories were blocked off for the first part of the flight by the food cart. Then some minor turbulence occurred so the fasten seatbelt sign came on for the second part of the flight. Heroic containment engaged! It was not fun.

Thank you for waiting for us after our first flight was delayed

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

The flight went well, only during the flight from Brussels to Vilnius I would have liked if they had at least given us plain water to drink.

The boarding process would have been better. When people are flying internationally and the airline is a member of Star Alliance they cannot have different rules for carryon baggage. Brussels Airlines made us adjust the weight of our carryons based on their rules even though we were flying international and our next flight was with United which does not have weight restrictions for carryons. That was just ridiculous.

We waited in line for more than 30 minutes to go through the check in (after the staff summoned us). Once on the plane we had to wait almost two hours before takeoff. The copilot said that it was not their fault but that the plane had arrived late in the first place and lost the slot to leave again because of the heavy traffic, This is completely understandable in our times, but I would have expected a little bit of pampering from the staff. We received a tiny little cup of water because we complained. Not a coffee, not a cookie, no music on the plane, no plugs to recharge your cellphone. It was very cold inside the plane and someone asked for a blanket for a baby - very harsh answer from the staff, no blankets on this plane. I think they should review their instructions and team spirit as traveling is also the experience, not only getting from A to B. And it’s not fun to interact with staff that doesn’t seem like they are enjoying their job. And as far as I know and judging from the cost of the ticket Brussels Airlines it’s not even a low cost!

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

This was absolutely one of the worst experiences of my life. I came to Europe for a 2 week trip and the airline was probably the most disorganized airline I’ve ever seen in my life. They lost my luggage. I had tracking on it for just such an occasion and told them EXACTLY where it was in the terminal and they somehow failed to get it out on the flight that night, since we were leaving for Switzerland the next day there was no way they would get it to our hotel in time. Seriously, take another airline at any cost. It’s not worth whatever you pay…you’ll end up paying a lot more in the end. My medication is in the bag and I can’t get to it and don’t know how I will get it.

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

There was no useful information given regarding the flight back to the UK from Tenerife. This despite the week publicised problems around the EES system and the delays caused to boarding. This aspect of the customer experience could have been much better.

Fast boarding, smooth takeoff and landing. plenty of space in seats. Excellent air-conditioning on a hot day. Perfect experience

Sitting on the last row in between the aisle and a massive person, all people going to the bathroom bumped into me including the flight attendants.

The best budget airline in Europe. Flight was on time, crew friendly and worked hard during flight and were able to meet our needs. Only downside (not the airline's fault), there were no rear steps.

It was transportation nothing more. I will give a positive rating over Ryanair. We missed our Ryanair flight the night before and received rude and unconcerned treatment from the Ryanair customer service. It was late. We were very tired and stressed after doing our best to get to the airport. The so called customer service ladies were completely unconcerned from the start. Aside from that, the flight to London seemed to be their opportunity for advertising. No time to relax as attendants were constantly in the aisle selling. I will never fly Ryanair again!!

Would not advise EasyJet for a 5 hour flight…small plane and hence a lot of turbulence. No inflight entertainment so struggle to pass time in cramped seats. We also fell victim to extra charge for our cabin bags, although bag dimensions were ok, but the handle was rigid and slightly fell outside their testing cage!!….never again will we fly with this airline and be party to their scams for making money!

The food and so are to expensive and old . Crew whas not very friendly . Apparently some other passenger can just Push through the waiting people to board while almost punching me and a father with a child down the stairs. Its always something with easy jet . The seats of row 26 where lose . And for a guy of my size there is absolutely no leg room at all .

Seats, WC,sizes for today's generation adults, and if technical problems arise a complimentary coffee, water nice for waiting one hours, the rest is perfect (pilot and cabin crew)

We accidentally purchased twice the bags we needed. Our fault, but the ticket was not clear to us, and it asked us to purchase bags at checkin. When we notified them to get credit back at the airport, they said to contact customer service. We flew the flight and then contracted customer service. They said no credits after the flight has flown. Not customer service oriented at all. They know we didn’t check that many bags and kept our money for a service they did not provide. Be aware and very careful of what you are purchasing from them because they will not make it right if there is an error.

Kayak sent several notifications that the flight was late. This contradicted the information on the airport boards. This was extremely confusing and we very nearly missed the flight purely because we double checked with the info desk when the flight stays said’closed’. Kayak notifications are therefore unreliable and pointlesa

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

The flight was delayed by an hour. Made the connection uncomfortably tight.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

No internet, very narrow seats insufficient room for three passengers with encroachment.

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

Give at least coffee or juice as it is an international flight.

Not enough food for a 4 hour trip…Lack of entertainment and with no WIfi accessibility I didn’t figure it out how to access free WiFi

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).
