I missed my original flight due to miscommunication and it was a challenge to communicate with service personnel, since my Portuguese is limited. However they got me food and a hotel overnight and a seat on the next available flight.

I missed my original flight due to miscommunication and it was a challenge to communicate with service personnel, since my Portuguese is limited. However they got me food and a hotel overnight and a seat on the next available flight.

In flight from Miami to Anchorage, we were all on board ready to take off. Pilot decided to take on more fuel causing a delay. Once fueled, the pilot came back over the radio stating more delay due to VIP. These delays caused me to miss my connecting flight. I went to the Alaska Air counter for information. They flat out stated that it was ATCs fault that I missed my flight and booked me a flight the next day about 1300 . I believe if we had the fuel prior to getting on board we would not of been delayed and I would have taken off on time. Pilot was taken out of the equation. I think they should’ve taken responsibility for their pilots decision to top off his aircraft instead of waiting til the last moment. Enough said…

I booked a flight through Kayak to Brazil I have traveled to Brazil several times before Kayak Delta or LATAM never mentioned during the booking or in the pre flight process that the visa requirements to visit Brazil have changed earlier this year. I was unaware of this change and as such never got a visa and was unable to fly from JFK to Sao Paulo Add to this that Delta allowed me to fly from Boston to JFK which they should not have as I didn’t have a visa. It has been a terrible experience and a huge loss of money

Wish the seats were a little more comfortable.. it was a 6 hrs nonstop trip. But the crew was courteous and w a smile

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

TAM is a real disappointment. We had to jump on a crowded bus for a 6am flight - although there were at least 15 available fingers that could have been used by our plane. Then, we were placed on row 30 - the last row of the plane, despite having purchased the tickets a long time ago and being TAM gold plus members. Note: worse seats on the plane. Great way of rewarding your frequent flyers TAM ! I now remember why I stoped flying internationally with TAM and moved to American, United, Swiss, Lufthansa and BA. TAM has no respect for its customers.

No air in the middle rows. Had a hard time breathing. Was dying of heat.

I loved how polite the crew was even though some of them wasn't the best with English that they still done everything they could to help me with my needs food was amazing

Liked check in process To improve: food and beverages. Not second round was offered and meal had no salad.

Check in of my luggage which needed to be paid for was excellent. Thanks to Nora

Special AVML was terrible Movie choices were quite limited Otherwise excellent

My seat was the only seat where the tv didn’t work. The crew Carol and Jua were very rude and refused to move me and my companion to a seat where the tv was working. I traveled on a 8 hour flight with no entertainment nor able to choose my food. I was told by Jua to call customer service for compensation. The customer service team and escalation team refuses to compensate me even after verifying and speaking to the flight crew, whom confirmed they told me that. Horrible service, horrible freezing cold flight. I would never fly Jet Blue again.

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.

Check in was excellent thanks to the team at the check in counter. I was disappointed to see that one has to pay for coffee on the flight. This is the first time I have seen that after 60 years of flying.

Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

The AB 330 was unbelievable comfortable. The 2/4/2 seating was great. Everything about this trip was wonderful except .....for the chili which looked like cat food!

The staff were great - very friendly and chatty. I checked in online at 9.30am, when check in had opened at 1.30am, and choices were already very limited, so act fast.

I suspect that there was an item pilfered from my bag at the TAP automated check-in counter on March 26th at Heathrow Airport around 11:30am. I think that the employee assisting me with my bags took something out of it when I was not paying attention because today, March 27th there is a notebook missing. Please check the camera to see if indeed this occurred. My description: Male, African Decent, 5'8, 180lbs medium build, wearing trousers and a jacket. Employee description: Female, Indian Decent (guessing) 5'7, slight build. Flight 1359, London to Lisbon.

Convenient, I m a SKY TEAM ELITE PLUS MEMBER, was offered to ship my carry on small case at no charge, boarding went easy & smooth, flight packed, we had a delay fo 45 mins, simply waiting on board, not sure, what was the reason, may be clearance to leave the airspace,

We waited in the jetway for over an hour before we got on the plane.

This flight was delayed by more than an hour. The seats are uncomfortable ans do not recline properly. I prepurchased a wifi pass, but wifi was not working on this flight at all. The food was bland.

Need to pay for headsets, water, or any extra except air to breath.

Sitting space was very tight and I am not big or fat (I am 5'10" 178 Lb), so eating was very challenging. The rest was good.

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.

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

Very BAD crew service They ignore at all any call for service . Very rude from the check in process to all the tripularion members in the fight .

Impossible to check in via the App. Kept on getting emails offering upgrade. When followed through not available. Wasn't any food anyway.

I was in flights from sap paulo <-> Madrid, the last one 11/15/21, That takes around 10:30 hour. Can you imagine that is served only a POOR meal after one hour of flight and nothing more??? We don’t have any service (besides in the morning a payed kart) or crew working in anything more than masks control. You need to pay for water / coffee is reasonable ? Even if you consider as low cost flights that you payed around U$ 700, courtesy and education should be showed by crew, things that Air Europe should learn to their employees on the airplane, a very rude people!!! It was not with me, but a complain for a lot people around. I have never been treated Like this before. Air Europa your journey will be short walking in this road. I, a constant traveler, will never more flight with you. I don’t need this kind of services!

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

My only issue with my flight to Jersey was that the Gate wasn't announced until shortly before boarding, otherwise all went well even with how busy Heathrow was. I appreciate British Airways staff's politeness, hospitality and positive energy.

Boarding was smooth and speedy. Pilot explained route and that even though we taxied a little later than planned a tail wind meant we landed earlier than expected.

Cabin crew was very good. No wifi and no doors to the suites

Very timly. Great service !!! Pick up after meals can be swifter.

Straightforward boarding process. Pilot kept us informed during the flight, especially highlighting the fact that we would experience "significant braking" when we landed on the short runway in Florence. The flight attendants were pleasant. My chief complaint is that I was stuffed into a seat in the rear of the aircraft (row 29?). The seat pitch was soooo tight that my knees were hard against the seat in front of me as soon as I sat down. One inch more room would have made a difference. Thankfully it was not a super long flight, but it was quite uncomfortable and I had to work out the kinks in my knees once I deplaned. Is it really necessary to have the rows this close together??

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place

It’s a new plane, but the most important detail is that the economy class seat doesn't recline—it’s completely fixed. The only one that reclines is in Comfort Class.

I had bad experiences before now was excellent I am glad they have business class again

This low cost airline looks and fells more like a local bus. In a 6 hour flight not being able to recline a seat is torture. The only thing available with no charge is a glass of water provided by, mostly, rude staff. Our luggage didn’t arrive

The seats were uncomfortable and barely reclined at all. Very little leg room despite being business class. The crew was friendly and the food was good. Had to use my own phone for in-flight entertainment.

Late departure. When the flight arrived in Medellin the plane sat at the gate for 20 minutes waiting for a bus for us to get off the plane.

I enjoyed it! In that case, I should have been offered this choice. On my first trip to Miami, I was asked to pay $320 for my luggage just for getting it totally broken. I cannot accept this situation at all!!!!

Overpriced checked bag price of $120 and they charge you for carryon if the size is not minimal of $120.

Felt very cramped in the back of plane. There was an hour delay for take off sitting on the runway, but we did arrive on time. They charge $120 for carry on bag and backpack at the airport its ridiculous.

The personal at the front desk in Manaos was awesome, I have never experience anything like that before, the person who attended me deserves to have a promotion I still remember him, very educated, kind but overall he could put himself on your position

It is better at the jfk than my home country. It was very easy and everything was on time.
