Pros: "Yes overall probably the best flight to Chennai from DC"
Pros: "Crew was very friendly"
Cons: "I don't understand how this company has a high rating in service. We missed our connection because the plane was delayed and they treated us poorly. How can you have a complimentary lounge for people missing their flight but not allow people in. I guess because we were only economy. When asked could we pay for an upgrade to business class, the attendant responded with "oh, its expensive" I didn't ask how much, I asked if we could. I never felt so insulted. The food was terrible. By the time they got to us, our food was cold and they ran out of the menu item we wanted. I have no intention of flying Qatar again. I will stick with Emirates"

Cons: "Ground crews remain the downfall of this airline. Long line in Doha to re-clear security on international connection FROM USA! Fastidiously weighing and forcing mutiple repacks of carry-on bags even though well under total limit of checked & carry. (Doha agent told me dfferent rules appied for carrry on 2nd plane even though I asked specifically frm original agent who checked me thru to final dest--insisted I check main carry on even though there turned out to be plenty of overhead room on board). Poor coordination of checkin lines, security lanes, and flow of people -- all fixable with a little forethought, engineering, and better utilization of circulation space -- and much clearer communication!"

Pros: "The leg space is what got this flight a 3 star."

Exceptionally poor performance by an airline you expect more from."

Pros: "Good airline, great service, boarding process, on time departure and arrival"

Cons: "Train the staff to be nice and pleasant"
Pros: "Food taste"
Cons: "No water at toilet....??? No coffee....??? The the movie’s subtitles were out of time."

Pros: "THE FLIGHT WAS PLEASANT"
Cons: "I DIDNT LIKE THAT THE TICKET I BOUGHT DIDNT HAVE LUGAGE INCLUDED! I HAD TO PAY 100 EUROS FOR 1 LUGAGE. I COULD BELIEVE A LONG COURSE FLIGHT, A 10 HOURS FLIGHT AND NO LUGAGE! VERY ANOYING!"
Cons: "Probably the most uncomfortable flight I have taken in a very very long time. The ride was smooth but the seat was so terribly uncomfortable. I was in pain on arrival."
Cons: "We had to pay $120 for a checked bag because it “weighed too much”. The lady at the check in counter said they were weighing everyone’s at the gate so there was no way to get around it This however was a lie and they were not checking weight and people got on without having to pay the outrageous fee"
Pros: "The only salvation was the entertainment choices. ."
Cons: "The planes need to upgrade the seats. When we were served food if the person push their seat back your food tray would flip like two did on our flight. Staff was jaded and sarcastic. I'm glad I had a discounted flight. I'd be angry if I paid full price. Poor staff, seat architecture, and poor food."
Cons: "They are very sneaky and try to make you check carryon bags - for $120. Will never fly w them again."
Cons: "Gate location information delayed until last minute!"
Pros: "Not much"
Cons: "A modern airplane properly equipped with padded seats and provisioned with quality food. Charging outlets!!"
Pros: "The entertainment choices were good. The hot meal was very good."
Cons: "We would have appreciated water being served between the meals; it was a very long time with nothing.The cold meal was just ok. We paid extra for our seats and were very disappointed at being stuck in the middle where it is difficult to move or get up. It would have been nice to be able to actually"
Cons: "Passport control in Lisbon was awful and many people missed their flight in spite of them being made aware of the issue."
Pros: "very pleasant all cruise, and food very delicious"
Pros: "I’m taking offFlight was smooth and service was great."
Cons: "Flight was smooth and service was great. Long wait before taking off."
Pros: "The flight crews were polite. The short flight journey included a simple light lunch with drink."
Cons: "The flight departure time was delayed for one hour."
Cons: "No cnn or fox news in English"
Pros: "Nice staff"
Cons: "If you are seating at the end of the plane they never have the 2 choice of meal and you are force to eat whatever is left, it happens more than once, seem to be the practice and is not fair to the costumer"
Cons: "I paid for the upgrade to business class and is like wasting money, the seat on business class was not working good"
Pros: "There was nothing to like about this flight!"
Cons: "The seats were the most uncomfortable I have ever experienced. There was no leg room. My knees were in the back of the seat in front of me abd I could not move. Unless you are way below average height, don’t take this airline."
Pros: "There wasn't anything special to like compares to other good airlines. I would say crews attitudes and foods were alright."
Cons: "Doesn't have a USB cable to charge the phone and there were no perfume or toothbrush for the long journey. Also no apple juice."

Cons: "The A330 was old, seats weren't entirely in order, IFE was mediocre. Wasn't able to sleep well on the nine-hour overnight flight."
Cons: "Where to start. No soap to wash your hands in the WC. Air conditioning dripping water to a seat next to us. They run out of on food option we wanted. The flight to Lisbon was delayed. The plain was dirty. One of out seats the entertainment system did not work. We alerted the crew, they did not do anything to remediate these problems. Only bad experience of the trip. Portugal deserves a better airline than this one. Last the best of all, $90 dollars per bag we checked in, so we spent $360 dollars just to carry our luggage."
Cons: "The flight attendants didn't come around with anything to drink, except with meals. All international flights I have been on offer multiple drinks through the flight. They charged $80 for a suitcase. This was not a discounted ticket."
Cons: "Not good I book a fly"
Cons: "You can't reach them via phone and they are horrifically slow and difficult to get ahold of."
Pros: "Of no change is BULLSHIT"
Cons: "My round trip ticket was purchased and in the confirmation it stated that it included one free checked bag. i also went online to reserve a window seat which cost 12.95. When I got to the airport I was told I had to pay 110 for my one checked bag as well as they had moved me to an aisle seat. Basically scammed me out of 122.95. I have complained with ygthe airline and if it is not resolved I will not be flying with them again."
Pros: "Disorganised boarding and staff not efficient Plane was not cleaned until passengers arrived at plane and waited in buses while they finished cleaning, waited standing approximately 30 minutes at plane on bus"
Pros: "We were traveling with a 7 month old so boarding was made easy by the crew. Most of the crew were quite pleasant during the flight."
Cons: "The entertainment system hand piece failed so you were unable to select channels, turn the over head light off or ever call for assistance. We had to get another passenger to do that for us. Ultimately the light bulb had to be removed from the fixture. During the flight, we asked for more refreshments and were told we could only have water by a flight attendant. Upon arrival at our destination with a child in hand, our stroller was not unloaded at the gate so we had to carry our child and all that travels with him to the baggage area. For anyone travelling internationally, you will know this is generally quite a distant from the gate in major airports. The strollers and car seats arrived in baggage 30 minutes after the main luggage. When staff were approached they were short and appeared very disinterested in helping. TAP failed on this flight home."
Pros: "Boarding was easy, fast and efficient. Crew were friendly and welcoming. Complimentary snacks were welcome and nice."
Pros: "Hot food and real utensils Good entertaining selection Very nice staff"
Cons: "Everything went well."
Cons: "Their short flight from Frankfurt to Lisbon was not that comfortable. Seats were thin, close together. My knees were jammed against the seat in front of me. Glad the international flight was more comfortable. Somehow we did not get the memo that there was a 0 baggage allowance for an international flight. Most give 1 or two bags free. So when we had to pay 80 euros for each bag it started off our trip with TAP a lot disappointed. We still have to fly back and we can go online and pay before hand and get it for 45 euros each. Increased out ticket prices by 205 euros. Will make me take a second thought before I book with TAP again."
Pros: "Not much"
Cons: "Late as always"
Pros: "Center aisle seat was comfortable and pnethy of room for my carryon overhead and underseat."
Cons: "I would like to see all TAP planes come with a standard entertainment option on the headrest in front of you with the advanced menu option of movies, games, radio, etc. and ensure all headphone jacks are operational. (Thisnflight the screen was messed up...not something you want to look at for 8 hours. ) I couldn't eat half the food because the salad wasn't anything but cabbage and a tomato and the corn and meat dish was cold and weird. I don't know what the dessert was but I got it down. I think the sandwich I got before landing was pesto and mayonnaise but I'm not sure. I didn't get much of it down before gagging. I wish when booking a flight you were given the menu or you could choose early in the flight and then be served. I bet it would cut down on wasted food and money."
Cons: "Our tickets said our flight was at 11. We got to the airport two hours early but found out our flight was actually at 10 (they wouldn't let us to try to make it). The airline didn't take into account / adjust the local time when we booked. Multiple customers experienced the same issue. We had to buy tickets on another airline."
Pros: "Aircraft seem well maintained and crews are very nice."
Cons: "Boarding was a mess this time. The lady directing the boarding did not make clear where each group should stand. So The lady had to send most of us back which upset many. TAP should copy Southwest Airlines except self checkin kiosk are horrid no matter which airline uses it."

Cons: "Lisbon airport is a disaster. I almost missed my connection. Had to beg to be given priority, which was granted at the very last possible minute. Had to literally run to the gate."
Pros: "We got scammed out of the tickets from Justfly.com and Ethiopian Airlines turned us away without looking at our tickets. I am upset. Now I have to get more Covid Testing done and that will cost approx. $700 and new plane tickets. JustFly.com's customer service is misleading and deceiving. And they blocked my number."
Cons: "Background check your booking agencies and their agents."
Cons: "First safety"
Cons: "The cabin crew had masks to protect themselves I think against the threat of Coronavirus. We passengers did not have them. It looked awkward. How about if instead of handing out headsets they gave passengers masks?! Overall I enjoy ET."
Pros: "The crew members were very accommodating and friendly. They do a wonderful job. When I told them that the power was not working in my seat and that I needed it for my CPAP (I call it my anti-snoring device), they arranged for me to move to another seat where the power worked for the CPAP. When the power did not work in the new seat for my laptop, they offered to let me charge it in a more powerful outlet near the galley."
Cons: "The power didn't work for my laptop. It did work for my CPAP device. Some of the seat control buttons were out of order."

Pros: "I was a bit hesitant to fly Ethiopian Air for such a long flight (Dublin to LAX) however it turned out to be the best leg of multi-segment trip (all other flights were Aer Lingus or Delta and Ethiopian Air was far superior to both of those carriers). Flight attendants were friendly, the physical space was comfortable and spacious, the food was plentiful and delicious. Movies offered were relatively new and the IFE worked well. This flight is a continuation from Addis Ababa to LAX so when we boraded in Dublin most people were already onboard. It was a bit difficult to find space in the overhead bins but with a little rearranging of smaller packages by other passengers, we were able to fit our carry-ons in the overhead bin near our seats."

Cons: "I had a long layover in Addis and the hotel I was allocated to could improve its service. I was expected to be served breakfast in the morning. My flight was at 820 am There could be some improvement on food"
Cons: "The lateness. Very bad. 2h45min late, unbelievable. And also the airhostesses services are very poor. I have to claim more time before they give me water for my food."

It took a whole week for me to have my luggage back while it was sitting in the Philadelphia Airport for 4 days waiting to be delivered to my house. On top of that no one seems to know the whereabouts of my luggage. Bad customer service. Be aware when flying with Lufthansa."
