They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

They only had vegetarian food left on the flight which I wasn’t happy about. I didn’t get any food to eat at all.

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Great boarding, great short flight but no entertainment whatsoever. It was supposed to have wifi but that did not work.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

-Swiss airlines online check in app crashed multiple times -Zurich airport does not have very many bathrooms accessible to people with disabilities - closest disability accessible bathroom to departure gate was 1/4 mile away.

The service was flawless. The trip went great. I flew from Venice, Italy to Tampa, Florida. The issue is my bag (that I checked for free when checking into the flight) was ripped along the side when I collected it from baggage claim in Tampa, last night. I thought of talking with the Tampa baggage claim employees about it and see what could be done, but my bag isn’t a very expensive bag and I didn’t want to make a big deal of it. I’m not sure if I’ll be checking a bag anymore in the future.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

Nothing special.. they could have provided something to eat without a charge

Everything was great except food . It as okay not good not bad

This time, I traveled in the economy, and it was surprisingly better than the eco-premium (food, comfort, and crew were noticeably worse in premium!)

Edelweiss is now Nickle&dimming, not even a complimentary wine on the intercontinental flight. Sitting space is the smallest I have ever seen.

I have no complaints. The crew was attentive, pleasant and heloful

This was an upgrade to business class and really enjoyed the experience. Much better than my earlier flight and thank you.

The Lufthansa app needs a whole revamp flight got delayed and it kept showing original time. Communicate better with you customers

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

There is more space in this economy seat. It felt like a better layout, not so cramped.

The staff was not at pleasant as those on the first leg of our trip.

Crew was excellent. Sat us together after the airline changed our seats. This was the smaller plane/shorter flight so no entertainment or food.

Boarding was one hour late. Gate notification was incorrect (notification said gate 17, actual was gate 14). Took shuttle bus to board the plane. Late arrival of plane at Turin impacted travel arrangements to the event.

They canceled our flight right before it was to take off and then we stood in line for four hours to make other arrangements. It completely ruined our trip.

Flight boarding was delayed. Old, low capacity overhead bins requiring many to gate check their carry-on luggage. Beverages other than water were at a charge.

Getting boarding pass for international connected flight was a hassle. Huge libe to get boarding pass after two connected international flight is excessive to put someone on stress. They should provide online checking for all flights

We did not get to experience LH cityline Flight cancelled 15 minutes before takeoff No alternatives offered
