Original flight was cancelled and when i was rebooked by the airline, they couldn't seat me in the same type of seat as I had originally booked (went from window/aisle to middle/middle and one was a bulkhead seat, and other wasn't in the same class)

Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Getting to the flight was arduous and lengthy. The flight itself was good but the food option wasn’t a good selection. I need to do a Kosher option on my return. Flight crew were nice

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

No food was served on the flight. Boarding desk open two hours before departure. But they recommande to be there three hours before departure !! So we where a group waiting 1 hour in Line for nothing …

My flight from Toronto to PDL was one of the worst experiences of my travel history. I paid for an upgrade and did not receive it, and was also charged an exorbitant amount for a 25-inch bag, and when I tried to explain the situation, I was only told the flight was already over capacity. & I had to accept what I could get!, I am a frequent traveler and will not be flying your airline again!. The only thing positive in this entire trip wete the flight attendants, but other than that, everything else was very disappointing!

They charged us 100 Euro per bag on the return leg with no explanation.

Everything was perfect, clean and very nice staff. But the seat was uncomfortable compared to other companies and the food wasnt good

Flight wasn’t full so got to stretch out and sleep.

Boarding was delayed. Then when we queued, it took us to another long line to stand in. Flight had 0 entertainment. Not even a magazine. But they had a free meal and it was good!

You cannot add an additional luggage via the check in. It seems to be an issue with Azore Airline.

The facilities at PDL are absolutely appalling during a 4.5-hour connection. Passengers from multiple flights were crammed into a small area with insufficient seating and only a snack bar. The only bathroom was unisex, with one stall for men and another for women side by side. This is for hundreds of passengers. The connecting aircraft from PDL to JFK was downgraded/switched out to an Economy Class-only configuration without explanation, even though the aircraft with Comfort Class we arrived from FNC on remained at the stand. Those who paid for Comfort Class could not enjoy the better seating or catering. Food and drink aboard was sub-par. I would qualify it as one of our worst travel experiences in years.

The crew was great. The only problem is that electrical outlets were not working in what seems to be a half of the rows on the plane. Considering that passengers are asked not to use power banks, this leaves us out in the blue without any entertainment option.

Reasonably comfortable. We were about an half an hour late. But no personal impact. Seats upfront have a good amount of recline, but do not lay down flat. Food and drink can be improved. There are no soft drinks available on the flights. Water, juices, and wines are provisioned.

Not consistent with the food quality (I mean taste not freshness)

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

Not great experience - we were super late boarding due to issues with aircraft. Then when we finally all got onboard and seated and they started taxiing out to the runway they just stopped then turned around and went back to the airport. Apparently the crew “ran out of time” to legally fly us. They mentioned that they were about 2 minutes away from taking off. I understand the rules and safety but kinda wonder why they would have bothered boarding us in the first place? Had to go all the way back and de plane and then wait in a HUGE line to get a hotel (this is somewhere around 2:30am) finally got to hotel by Uber (no shuttle after 20min so gave up) and they ended up putting us all back on the same aircraft at 10am next morning so got about 2.5 hours sleep. They did give us. $250 credit, but it was a São Paulo Brazil flight out of Dulles. The flight and everything was fine.

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

United have really come back. Airport and boarding process is clear and good, app and information also very good

They charged a fee for 1st bag checked. Others in same party were free.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The movies offered were great. Staff were very pleasant and very efficient.

After a delay at the gate, C3, at Ohare on Sunday, I left my Blk ski coat on the bench at the gate, lost! Please review my lob claim, thx.

Very bad! They kept delaying my flight and wouldn’t do anything about it

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

Wonderful just hope the had more direct flights to Boston

Boarding process was fast and efficient. Short flight but on time and well organized. I would certainly fly TAP again.

Very borderline, low budget airline without low budget prices There are no counts of soda, everything is dispensed enlarged bottles and poured into tiny cups about 70 mL so in order to keep hydrated you have to take 3-4 cups at a time. Also, there was only one food item offered, pasta, they ran out of chicken right away. Snack was very poor. It was called tuna sandwich, which is truly borderline. The flight attend attendance seemed to be overworked and tired.

TAP‘s flight attendants seem to be among the least ambitious of all the international flight crews we’ve flown with. . When we left US and went to Portugal, and when we returned from Portugal, flight attendants were not very visible. Then did not offer frequent water breaks and when we had to go back to request water, I was almost an imposition. Meal quality was just average. The dinners were fine. Breakfast wraps were presented soggy.

Plane was delayed, reading the gates on their screens was horrible. They posted it a half an hour before the plane boarded. By the time I got there with my premier boarding they have filled the plane because it was over booked. Gate closed at 12:03 I was there at 11:54 plane took over around 12:20. I was told they would put me on the next flight. I had to go to TAP information desk. They didn’t give me a voucher they just said they would put me on the next flight. At the desk I was told I had to punches a ticket. The woman said buy it online because it’s cheaper. It in fact was not cheaper. But I had gotten out of the long line that formed so I paid 200$ for a new ticket. At a later flight, not the next flight. I had checked my bag and was told it would be on my new flight. I was then bumped to an earlier flight and was told my bag would also be on my flight. After landing in Madrid loosing a day in my hotel i landed without my bag. They didn’t load it on any flight that day. It arrived in madrid the next day. Essentially ruining the first two days of my vacation. I’m now seeking compensation.

Did not enjoy the meal provided. The aircraft was dirty. For instance, the screen seemed to have been cleaned with a dirty rag. Disgusting.

The business class seats were smaller and closer together than other airlines.

Boarding- Good Seat Comfort - OK Crew - Good Food - Mediocre On Time - Very Good

Didn't like much. Wheelchair assistance was almost nonexistent. No one at TAP check in process helpful. On the plane, stewards were not friendly and disorganized. Food was terrible for 8 hr flight. We were skipped at snack time and even though we tried to get attention using overhead call system no one even looked up at us to acknowledge. Being at the back of first section and by the lavatory we only were able to request when they came to pick up everyone else's garbage and they were nonchalant...no apology or even choice. The 1/2 half bread with slice of cheese was a waste. Deplaning was horrible but I'll blame lisbon airport for that. Plane left late at made good time still arrived about 15 behind schedule and for using remote deplaning and bus to terminal took another 20 min to gate. Those with connections were highly stressed. Took us 2 hrs from landing to get to ground transportation and exit airport. And that was with wheelchair assistance.
