Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.

Issues with plane led to multiple gate changes and chaos. Very little communication from the ground crew led to cranky passengers.

I flew business class, at breakfast I asked for a small bottle of olive oil instead of butter and the flight attendant responded with a negative gesture.

They didn't even give us water, everything was sold

They should at least offer water like other airlines, which seems like a humanitarian gesture to me

They gave me an upgrade but charged me for my bag. I felt abused because this had never happened to me before with an upgrade with another airline.

Well. It is a no frills airline. Annoying is that even for the long-haul everything has to be paid for separately. Once you add up the extras the flight is getting to expensive. Then one might as well fly with a legacy carrier which provides far better comfort. Changing flight at MAD airport is a nightmare. The worst airport in the world. Poor signposting, poor passport control, poor security check and long queues. I had 2h transfer time and spend in queues almost 1.5h

All flights with Air Europa you arrive late to the connections of other flights, I missed my train, I had to pay for my train again, the crew are antisocial, you are paying for a service, it is not free, thanks to the travelers they are there, it is the last time I fly with them,

Terrible experience - we won’t be flying with Air Europa again

The crew was not kind , just doing their job but very cold people

Chairs do not recline. Finished the trip with an aching back.

Iberia lost my bag, said they found it in another country, said they sent it to me, but never did. Went my whole trip without my stuff, but expecting it to show up because that’s what they said would happen. Their communication sucks, their website sucks, and to top it all off, their seats are small and uncomfortable. They’re bad at their jobs and they should feel bad about themselves. Do not even get me started on the flight home. AVOID!

The flight was delayed over 4 hours. Business class is just slightly upgraded economy.

One of the crew members hit me with the car and not even says anything

It was a wonderful experience with great food, great staff, and no difficulties boarding!

There's not enough leg room in economy class. The seats are very narrow as well.

Well my luggage was damaged and they lost the plastic cover. I need to file a claim and I would like for someone to follow up with me on this. Thanks.

Provided a good service and I will use it again. Thanks,

Boarding was not well coordinated. I asked twice at the Level check-in area about the MIA flight. At no point did they say the check-in would be at another counter. Fortunately, another passenger was equally confused and got the REAL story from the airport’s info center. Further, my minor child was tagged “SSSS” on their boarding pass. Level should have notified TSA about him being a minor. Instead, the entire family went through the SSSS process, not just our son. When his name was called out at the gate, it was announced in Spanish. No English announcement was made. The food on board was bearable. The crew was adequate, despite not being Level/Iberia crew (Level contracted out our flight to “World2Fly Airlines” - a company I have never heard of!). The onboard entertainment was very limited. They did not even offer a flight tracker option. Nor were music selections offered. Like TAP and Aer Lingus, I will think twice before booking Level ever again.

You get what you pay for. In general I like the service and flight attendants.

Comment for Lufthansa is just perfect, similar to my first flight comment.

Flight delays made me miss my connections. I almost missed my connecting flight because I had to get my luggage and go through immigration and then back into the airport. Connecting flight said it would be my problem if I missed it. I had to be rerouted through another city and came in 3 hours later than expected and had to hire an uber to get me home when I had everything planned out

The food not that great. Did not like the fact that we could not purchase upgrade at the airport

Overall excellent service and Frankfurt Airport was very efficient and clean

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update

They are professional. Nice crew. Still flying Boeing 747. Thank you for that. I love this airplane. Traditional.

I flew from Brussels to Munich, then from Munich to Denver. The flight from Brussels was only about 2.5 hours and it was okay. But the flight from Munich was about 12 hours and we sat on the plane for a very long time after everyone boarded. I paid something like $75 for a “preferred” seat in economy and it was so cramped my knees rubbed against the hard shell pocket. You couldn’t turn your legs to the side because the passenger next to you was too close. I was on the aisle but couldn’t put my leg out because there was often traffic or carts. Maybe I’m expecting too much but on such a long flight I’d like to see more comfortable seats. I think it was a United A380 plane. I won’t be flying anywhere that far away again. My legs and feet are still swollen 4 days later.

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

Connection time and departure time were both changed to cause undue stree on older people who cant run through an airport

Problems checking in. Charged for bag which was to be included. Repeated trials with in line check in process

The crew were great and constantly cleaning bathrooms and taking care of passengers. Flight was on time and arrived on time. Boarding was easy and hassle free. Food could have been better but decent selection. Overall recommend and will fly again.

Everything was good except the bathrooms were usually dirty and the trash bins in the bathrooms were full.

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Two of my four flights had issues with toilets either NOT fully operational or completely out of order. Boarding was a joke because they have NOT established who is running the show. In the end, she did a terrible job. The seats 💺 were loose goose and the drinks and snacks were limiting in choices. Also, following Alitalia as an inspiration was strange since they went out of business.

Boarding was chaotic. Service was poor. Attendant was slow and rude. In business class, I was not offered a drink until 1.5 hrs,after takeoff. Food was inedible.

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

The flight was great. I don’t know about the food because I was asleep and they didn’t leave me any.

Seats weren’t comfortable. Both of our seat backs were either almost straight vertical or laying back into the laps of the people behind us, which is a weird angle to try to get some sleep even on a plane. No in between. Also, neither seat would spring forward like they should.

The flight was great, smooth and even a little ahead of time.
