I have greatly enjoyed Tao Portugal. Nice service. Just be aware they weigh both your carry on and your personal item at the same time at the airport counter when you check in for the flight. Both can not excede 12 Kilograms.

Both flights needed a bus from terminal to plane and plane to terminal. The transfer to the connecting flight at Lisbon was quick and easy with luggage checked thru to Venice.

Make sure you arrive early enough for boarding. I had a 1 hr layover from Charleston that that was just enough time to get off the plane and walk over to the international side before they started boarding.

Weigh bags. They will check. Check in with gate or desk. Sometimes the e ticket will not work for boarding.

I was waiting for a flight boarding announcement in the Lounge in terminal C at Logan Airport in Boston, but the announcement never came. If I did not go to the gate to check, I might have missed the flight. So, do not count on the airline to communicate flight boarding information to the lounge staff. They are supposed to do that, but, apparently, sometimes it does not happen.

Airline reviews

Our flight was delayed multiple times and then canceled at almost 1 in the morning. We are a family of 7, traveling with 5 young children. When the flight we were supposed to fly on finally arrived after waiting all day after an international flight into JFK we were informed our flight was in need of a copilot and once they located one we would take off. Then our flight was cancelled because the copilot was over his hours and they couldn't locate another. They knew before taking off from the previous location that the copilot would be unable to fly. They could have communicated the cancellation of the flight hours in advance. Once they cancelled and the pilot and copilot got off the flight, they joked about it. While there are understandably limits on flight time for pilots, they can still handle the situation in a professional manner. The late cancellation resulted in angry passengers that required police intervention in the airport. It also occurred so late and included other delta flights that after trying 15 different hotels, we were unable to secure a hotel room, they were all booked. No rental cars were available in the area either. We ended up staying in the airport with the 5 children. We made it home after 54 hours of travel with maybe 2 hours of sleep. Our luggage was lost and had to be claimed at the airport at our final destination. This was the worst trip I have ever taken and the worst airport I have ever spent time in. I met two individuals in the airport that were kind and helpful; Tonya Maingot Williams from the can we hel desk that worked to help get us rebooked and home, as well as provide us with care bags for our extended stay in the airport. The other individual was Danielle from Buffalo Wild Wings that was so very kind when we found a place to take our family we were traveling with to eat, all 11 of us and we were able to sit down together to enjoy a meal during such a stressful time.

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

Very good seat and service. No complaints about the food. Take off delayed due to airport traffic

It is usually very pleasant. Good service for the price, international flights are even better

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

We had a terrible experience. The flight was delayed several hours, so we missed our connection. We were told to wait at the airport. At around 11:00 pm, the flight was cancelled. There were no available seats out of Jackson for the next two days. Fortunately, we had the foresight to rebook on United for the next day. However, we had to spend a long day at the airport and an overnight at a mediocre hotel. It was a miserable way to spend part of our vacation. We also sacrificed our $450 deposit on our California hotel because we could not get there.

delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Overall Delta was amazing from automatically booking us on the next flight once we missed our connection due to a delay to the constant communication throughout the entire process. We will continue to fly Delta going forward more and pay a little more if needed.

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

Worst service- attendants dont want to help and sat us in front of bathroom

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

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.

They blocked me from checking in online and they charged me lots of money

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Not have my bag forced to be checked when I had a carry on included on my ticket. Staff was very rude to me for asking why they were doing this. I was told there was no more room for carry ons but there was plenty of space in the overhead compartments

The crew was excellent. What I did not enjoy was the food. I have taken many international flights and this was on the low end. Otherwise the trip was fine.

Seats were the most uncomfortable seats i ever experienced on a flight to Europe from Boston. It was a waist of money in buying premium seats for top dollars. I want my money back for what i paid extra for my seats. Awful conditions!

Boarding felt a little chaotic as everyone was waiting around the gate. Food was great, service was good.

Flight attendants in business class were rather indifferent While in second leg operated by Portugalia TAP subsidiary were outstanfy

The chicken was so dry it was impossible to eat. No substitute was offered. The port to charge my phone was broken and all I got was a shrug from the crew. The entertainment system was glitchy and subtitles didn’t load. Crew seemed fully uninterested and unfriendly.

The flight crew were absolute rock stars. When they came to the gate they looked like royalty, so chic. They also were extremely kind. Food was good and I loved the lack of plastic waste. The flight was lovely and smooth.

We were unable to check in due to technical problems on TAP’s end. The flight was delayed forty minutes with no reason given. We received timely notice of the flight delay. We were also notified of a gate change. The new gate was at a different terminal. When we got to the new terminal, we learned that we had to go back to the old terminal first to check in. This information should have been included along with the gate change notification. Also unexplained, the steward skipped us when offering breakfast.

Initial flight had an engine overheat - returned to DFW. Had another plane ready, but crew timed out. Had to wait 5h for boarding. Fully boarded and pilot says plane is not flight worthy. Deplane and go to the other end of the terminal. Wait an hour to board third plane because the crew couldn’t leave the second plane because no wheelchairs were brought to remove passengers. Finally take off and there is no catering (in flight service) even in first class. Very much an AA failure.

We were delayed due to a mechanical issue, but the gate staff and then later captain were giving thorough and frequent updates. Ended up being delayed about an hour, but we did get out, so it was overall a good flight!

I was able to check into my flight through the app and online but had issues getting my boarding pass once I arrived to the airport.

Ninth consecutive American flight I have been on that was delayed

Would have been good to have the live TV outside of the continental United States as AA was promoting they are sponsors of the Fifa World Cup only for the live coverage to end.

Terrible check in experience in Miami airport by a so-called supervisor. Food came and they were picking up trash within 5 mins. Did not get fed again for about 6 hours. No chance to buy anything on board, horrible experience. Flight attendants have no control over passengers dropping off bags closer to the exit, not close to their seat.

I will never but. through kayak again. and American Airlines. I will never fly again on. They're both thieves.

It’s love good long way travel!! I always want more give me price down i want ever month travel I miss travel only North Carolina to Thailand in my love her !!

The departure and arrival was on time. The fact that I could load my boarding tickets on the American airlines app.

Bathroom ran out of TP and floor was wet. Crew seemed a bit unhappy, overnight flights may be harder.

ok. It's a short flight and it was delayed, hence the ok rating.

It was not British Air, we were put onto Air Portugal for our London to Lisbon leg.

Horrible leg room - coach seating with empty seat in middle on a 3 across seating. You buy business class for comfort which includes leg room. Absolutely no entertainment options either. Awful experience

The on flight entertainment system touch screen system and the USB charger did not work on multiple seats on least 4 seats an in different rows. The attendant tried to reset the system but was un successful. I couldn't change my phone to get my ticket for my next flight. This was an international flight I changed seats and the problem was the same. the flight attendant offered his power bank

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

Once again I purchase a business class ticket and the seat is exactly the same as cattle class, the only difference being is that BA install a janky table over the middle seat so there is somewhere to place your complimentary drink, the tray table is just big enough for the small tray, so if you are not concerned about getting fed and watered on the plane or getting access to the BA lounge I would save your money and fly cattle, PS the cabin crew were exceptional in every way, shame about the equipment

When bussing people to/from the gate, don't pack everyone in like a can of sardines and don't send the bus on its way if the plane isn't ready. Waited for about 40 minutes packed in this bus...both ways!

A Perfect 2.5 hr flight. No amenities, but we did not expect any.

Delayed flight by 45 minutes. Need a refund to compensate for the subsequent itinerary changes

The flight was delayed and absolutely packed, we had to dispach our hand luggage which contained some fragile items, luckly nothing was damaged.
