Cramped seats. FAA should make airlines have more legroom, for even short people complain

Cramped seats. FAA should make airlines have more legroom, for even short people complain

5.5 hour delay with no explanation on why, along with no proactive effort to reaccomodate me.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious. this return flight not as tasty, but filling.

The flight was 2 hour delayed, otherwise everything was excellent. The delay was due to the hourly limit requirement so given that as a reason, I'm happy with the flight!

Weather delay for 2.5 hours followed by half hour crew delay, did not have ginger ale, uncomfortable seats

My luggage got lost and until today there is no solution to the problem. It's still missing

I am writing to demand an immediate refund and compensation for the absolutely unacceptable experience I endured with VUELING this week. On Monday, my flight was canceled, and despite this, I have yet to receive any refund. I was then taken to a hotel in a terrible location, where no food or even water was provided. The next day, I was rebooked on another flight, for which I had to personally cover an additional €50 in transportation costs—only to have that flight canceled as well. After waiting 10 hours, only 10 of us were offered alternative accommodations, while the rest were left stranded. We were forced to remain in this situation until Thursday without a single explanation or proper assistance. During this entire ordeal, we were only provided with breakfast and dinner, while being charged extra for drinks. This level of treatment is completely unacceptable. I expect an immediate refund for the cancelled flights and full compensation for the inconvenience, additional expenses, and the significant distress caused.

Only food for sale. Did not even offer water. No entertainment

Checking was efficient and quick. Adequate luggage space. Food for purchase only at high prices

Nothing. There was no flight. They cancelled the flight with no replacement about 9 hours before takeoff.

The flight was canceled at the last minute. Alternative flight was booked after 6 hours wait in Malaga airport.

Boarding with some sense and communication. It was a total free-for-all everyone coming all at once, no organisation of row numbers or priority.

Horrible, flight cancelled and had to come back the next day

Terrible. For clarity - this was the Level flight to Boston. Not Vueling. Would urge customers to avoid this airline. Gate agent was singularly unhelpful. He was argumentative, rude and went out of his way to ensure that every penny was collected for the baggage (which we realized given how early we were for flight we could have saved hundreds of dollars if we checked in on app). No onboard entertainment or WiFi. Half of the front section was empty because the seats did not work! Plane was falling apart.

No complimentary snacks, but I think that’s a standard in the USA. There were loud drunk Germans sitting in front of us.

Food was edible, not great, and served by attendants who looked like they really were not happy working the flight. The section I was in was too warm making the 11 hour flight uncomfortable. Other areas on the plane were fine.

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Very pleasant flight, crew was very nice. The flight was really smooth, big plane. The seats are kind of close together, so comfort was just OK. The boarding process on the way back to New York was a little chaotic. It took a long time.There were no announcements, no loudspeaker just one staff yelling out of instructions and a lot of people crowding in before their term to board. So that could really be improved a lot.

Little leg room in business. I am tall and could use more.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

I’m still missing my bags. I’m soo frustrated

Not having to check carry on bags when plane wasn’t full. (The told us it was)

Service and food were excellent, could have been more info in English.

I was in business class for the 8 hour flight where: 1. The WiFi did not work 2. The entertainment system did not work 3. We were told there were no hot drinks for the entire flight

I had an issue with the name on my ticket vs my passport name. I was very upset that the Iberia ticket clerk had no authorization to help me and I was left to fix it. It took 19 calls of persons promising to accomplish and not doing anything before I reached someone who helped me in 10 minutes. Two of them even hung up on me. I missed my original flight because of this. Terrible customer service.

Flight boarded three hours late for no reason other than someone made a huge error in crew scheduling. We missed our connecting flight in Madrid and got zero help from American or Iberian airlines on rebooking. We had to pay for a car to take us to the Madrid train station and pay for train tickets to Santiago. We never used our booked flight to Santiago. American claims I can submit the expenses but they are not obligated to cover them. Very frustrating.

Flight delayed Service could be better Iberia staff are not really friendly

They cancelled the flight)(they said bad weather but many other flights took off) and made us wait 5 hours in line to figure out what to do. We ended up making a new flight the next day on another airlines...I hope they honor giving us our money back

Flight from Costa Rica to Madrid was excellent. Good food and service. The flight from Madrid to Brussels was very poor . No food , no entertainment, no usb … Total package was quite expensive so you should give same service on the second flight

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

business class food was pretty average otherwise it was a good experience
