Airline reviews

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.

We had 2 delayed LATAM flights in our trip. We were only given one coffee for 5 hours delay. Also when we were boarding the crew wanted to charge us for our allowed carry on luggage. I got a bit angry and they finally didn’t charge anything. Not flying with LATAM again.

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

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.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

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.

The flight was delayed causing me to miss my connecting flight

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.

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!

After landing in Paris every one in the plane had to get on a bus which was packed and every Covid protocol was violated. There was no social distancing. It was disappointing. There was an empty bus right behind us. A few passengers asked to get on it to keep some distance between people but the driver refused. Probably you do not care.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

I purchased premier economy seats but I was seated one row off and was sitting in economy my bottle of water and cookie did not compare to the menus handed OP it in premier.

I understand and don't want food on a short trip, but tea and coffe (at least 1 cup) should be free. Nevertheless there was water available and the crew was nice.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

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.

Fly was cancel on the las minute wiht out tell me

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.
