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! 💗

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

I truly love flying with Delta. They have always treated me with the upmost respect

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight was great. The gate location was way to far away!!!

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

I believe that a four-hour trip should have a meal. Delta had none.

Was charged for my luggage despite having been on one ticket from an international flight. Too tired to argue after 15 hours on flight. Was charged for rechecking it at JFK airport. Not sure why those off Kenya Airways were required to do that.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

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.

Flight on time. Staff pleasant and responsive. Food could be much better. Snack before landing was a few dry crackers and a drink. Nothing else. There was a very lumited selection of beverages available on a 7 hour flight. No soft drinks, even in the front cabin.

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.

Flight and crew were great. United didn't inform crew of immigration process which was disappointing!

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Friendly and professional flight crew. Aside from departure delay after boarding, easy flight and smooth landing.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

Boarding was organized. Old plane. Seat fairly comfortable. Business Class much too large so you don’t receive as much attention as you should considering what you pay for the seat.

I had no checked baggage but was required to hand over carry on baggage at the door of the plane. There was a lot of overboard space in the plane and I was one of the last ones. I ran to get my carry on but it was gone. I was given back at the plane door in Toronto, so the wait was not as long as it would have been at the carousel.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

The food should improve! And The flight should leave on time and not make the traveler wait.

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.

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.

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.

Great staff, just very far from the main terminal, had to run to connect my flight. I had 90 minutes to spare. But my flight from Chicago was delayed also.

My luggage is lost and nowhere to be found, no response from airline

Boarding was a shitshow. Had to bus to the gate. No separate bus and boarding process for Business Class.

The plane was very old, no power outlets. We also had to wait a long time to board. They kept moving us to different lines before we actually could step foot on the plane. We ended up being delayed an hour but we were never told or informed for any reason. After the meal I asked for a coffee which the flight attendant forgot and I had to ask again. Overall not the worst but not the best experience.

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.

Sitting space was very tight, so eating was difficult. But everything else was good.

12 hours flight. Only one meal, not enough food. At the galley only water during the flight. Lavatories not clean. Headsets at extra cost.

Need to pay for a cup of water. No food. Need to pay for headsets.

Everything should improve! Service like a low cost but prices like a premium airline. Crew in general with bad manners arguing for everything. You pay for priority access but then they use buses, so your loose your advantage to put your carry on first. That was the purpose for paying for priority. Bording is a nightmare, people accessing the plane for bothering doors, front and rear, no matter which line do you have.
