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.

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

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.

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.

Our steward Margarida who served us from Lisbon to Boston was absolutely fantastic! She deserves a raise. Conscientious and thorough as well as showing appropriate attention for every need.

My flight from New York to Canada and Canada to Brisbane was canceled, so I had to take united airlines instead flight from New York to Dubai then layover in Dubai 8 hours then from Dubai to Brisbane it was extremely difficult for me , it was a nightmare flying with Canadian airlines unfortunately.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

It was okay until this flight had mechanical problems which made us miss our connecting flight and my friend and I had to pay an extra $500 each to get to our next location at a later time.

Efficient board despite a 100% sold out flight. It’s crowded on the plane but crew was working hard to get us off the ground on time and served dinner and breakfast. Food was good.

The Air Canada staff at the gate in Newark were fantastic and so very helpful!!!

Flight was delayed 1.5 hours as crew was stuck in traffic...that is absurd that the airline would be transfering a crew by car through NYC during rush hour. I missed my shuttle bus and got stuck in Vancouver for the night. Airline did not offer a voucher

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

Cold frozen fruit for breakfast was unexpected and a waste in my opinion. How about a warm bun would have been better. Otherwise great on time flight.

Very poor.!!! They cancelled our flight and rebooked us with very little time to catch the flight. Our luggage was lost. As of now we do not have it yet. No clothes to change on the second day of vacation.

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

I liked everything BUT the temperature. It was freezing and now I am sick.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

We were upgraded to economy plus and everything was awesome!

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.
