The best airline I have ever travel , really good customer service, attention and service !!

Awful. There was a minor problem with a fridge and they had us 2 hours in the runway before take off. The paper work alone took them half hour. There was no attemp to make up time up while in teansit and when we arrived, they had us another half hour in the plane because of traffic. I, and a bunch of people, lost their onnection flights for 5 to 10 minutes. Not even the attemp to wait given thar all delays, but the taxing, were United's fault. Then another 45 mins to get an agent and no flight alternatives for 2 days. Im am very disapointed with this "premium carrier".

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

Check-in was a little confusing. I paid for extra luggage, but when i checked in the system didnt seem to know. Arrived in Paris early after a late departure. Luggage arrived on the same flight with no apparent damage.

IT WAS A LONG TIME SINCE THE LAST TIME I TRAVELED. I THOUGHT I WAS TO BE LOST BUT EVERYONE WAS PRETTY NICE WITH ME AND MADE MY EXPERIENCE NICE. THANKS

I flew Delta last week and United Airlines is a poor substitute mechanical problems with the plane and shitty food among other things made my travel experience what’s become to be expected from United no way is it ever worth the money they make us pay

No in flight entertainment, gate employees were very quick and impatient, plane was uncomfortable

There was a delay that was unexpected. The seats were uncomfortable for the length of the flight.

One the best cabin crew team we have ever had (I have flown globally for more than 2 million miles), food was good and wines choices were great.⁰

I will NEVER fly with this clown show airline again. Idiots. All of them. Unprepared. Unfriendly. Miserable employees. NEVER. EVER. AGAIN

Easy experience even with the outbound flight being delayed. The seating and space was comfortable and the crew seemed very nice and helpful.

Flight was smooth, amenities (entertainment options and power outlets) were good, sears decent)

Disaster This is why I stick to delta You get what you pay for

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.

It was a pretty smooth flight, I tend to get mini anxiety attacks during flights, however, this time was pretty smooth and I was able to relax. The only thing, I was having issues to connect to the Flyfi internet. I was not able to connect at all, I turned off my phone a couple times and didnt work.

we were delayed because of some safety check that wasn't done or available

The flights are back on time and everything else runs perfectly.

They announced at the last minute that international travelers had to checkin at counter. This created a long line and unnecessary stress.

I cannot say this enough, I NEVER BOARDED OR HAVE HAD ANY TRAVEL IN THE PAST YEAR. However your app says ive been traveling a lot lately. GET REAL HUMANS TO GIVE CUSTOMER SUPPORT.

Not much space for someone 6 feet high in normal economy seat. My knee hurt

AA was a very good experience. The employees are wonderful

I couldn't use their app to select seats or check in because they made a business partnership with UnderPricer to control and sell those options when you purchase your tickets through that agency. And yiu can't get any assistance from UnderPricer. Vueling has made a terrible business decision to partner with them.

We had a very pleasant flight with very comfortable seats and nice staff.

Seriously, not displaying departure gate until very last minute is awful. Specially when you have to take an elevator and then transport to go to the sub-terminal. That’s awful in such a busy airport as Heathrow. And I cannot choose seat on this flight because it’s run by British Airways, even entering locator code.

Seats in coach aren't padded enough for a 6 hour flight

My trip was delayed for more than 3 hours without any explanation. Also I have a business meeting that I lost.

the handling of my luggage. It was Lost or stolen At my destination.

If we travel with carry on expected to being able to carry the luggage. Could be good if take in consideration the date of reservation to do that

Uncomfortable seats at row 40 A and 40 C, they didn’t recline. Also, my prior seat selection was not honored.

We were bumped out of bulkhead seats we purchased a year ago. We were moved to row 5 and the folks in row 4 fully reclined making it difficult to get out to use the restroom. The seat have too little padding making them uncomfortable 3 hours into the flight. The movies did not offer closed captioning and the earbuds were poor so the entertainment was mostly unusable. The food was just passable. I would not fly Iberia/level again. Iberia also bumped us off our direct return flight so I would say the whole experience with this airline is poor.

The flight was operated by level, who had a sister’s check in procedure (2 hours) due to understaffing and a computer malfunction. While 3 agents stood at the business check in, with a total of maybe one actual customer there at a time, a huge line formed at economy check in with only 1 agent staffing the check in. Then, my luggage was lost - a guitar case with contents inside valued at 3,000 USD. The computer system of LEVEL could not locate my bag and had no record of it, and IBERIA (with whom I purchased my ticket and the checked bag) refused to help. It was a disastrous experience and I will never book Iberia again

The flight was canceled on a Thursday last minute. I lost thousands of dollars in hotels and car rental

Excellent lie flat seat for premium economy! Great staff. Bad food . Not so great entertainment. My bag didn’t make it either.

It wasn’t great because the third-party from Kayak there was just no information about how to check in with Vueling. And the purchase of the ticket from under pricer just made everything really difficult. I’m unlikely to use Kayak again for these reasons.

It was budget airline Veuling, even though we booked Iberia.

Suddenly, I don't find my flight back on the app Help Ticket 0757345716866 Hoeflich Flight back Sunday ib5333 Ib2629 Ib4268

This is where i leave an airline review. Test test test!

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

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

After boarding, there was a small issue with the aircraft which caused a delay of about 45 minutes. During boarding and while passengers were being seated, the plane was being refueled. There were also a lot of unusual noises during the flight, which was not very reassuring. In addition, there was no WiFi or entertainment available.

Boarding, crew were excellent, food was ok and entertainment need to improve

There isn't much space in-between seats and even water needs to be paid for during the flight.

They charged for WATER on a SIX hour flight!! never again!

$120 for a carry on bag !!!!!! Insane. Back-breaking seats. Do not recline. Food service is a disgrace. They give only water and a salty snack. Everything else has a price.

I was shocked flying to El Salvador that they only give you water. Everything else you have to pay for. There is no wifi or entertainment and it’s an international flight. At least back in the day they had tvs on the plane and everyone watched the same movie. Also seats do not recline, even comfort or plus.

Seat space was terrible no food on a six hour flight

This is the Spirit of Latino travel. And don’t even get me started on customer service.

No comfort at all. You should add at least 1 meal or a bottle of water. I wanted to buy one sandwich and everything was gone.

Terrible Business cabin from GRU to BOG. I also flew from BOG to CUN on Premium seat, another disappointment. Not even water is offered for free! Avianca should be ashamed about this poor service.
