My seat was the only seat where the tv didn’t work. The crew Carol and Jua were very rude and refused to move me and my companion to a seat where the tv was working. I traveled on a 8 hour flight with no entertainment nor able to choose my food. I was told by Jua to call customer service for compensation. The customer service team and escalation team refuses to compensate me even after verifying and speaking to the flight crew, whom confirmed they told me that. Horrible service, horrible freezing cold flight. I would never fly Jet Blue again.

Bad boarding, threat to force bag check mid journey, lines, late, buses, more waiting awful end to end.

Terrible! I had to cancel our flights due to my wife Carmen requiring an unexpected second cancer surgery. I first contacted orbitz about obtaining a credit due to medical interruption and orbitz directed me to TAP. I contacted TAP and the representative directed me back to orbitz and refused to even explain what TAP’s medical interruption policy was or how it worked—I wanted that information for a second call to orbitz. Terrible service at a particularly difficult time.

Checkin was very slow, we had checked in online and hoping we could do a bag drop at the airport. However everyone with checked bags had to queue up and it took over 40mins. Our advice arrive extra early or you will be rushing to the gate.

Was a cheap flight and it got me to Portugal on time. For economy there was ample leg room and the flight attendants were pleasant and helpful.

Not having a delay. Not sure what happened with the service animal biting the crew member.

The staff were great - very friendly and chatty. I checked in online at 9.30am, when check in had opened at 1.30am, and choices were already very limited, so act fast.

Adequate. You get what you pay for. Absolutely no frills but a cost effective way to travel between European countries.

Very efficient boarding - other airlines could learn from them. Friendly, efficient crew. Red eye flight, so dinner meal was irrelevant. Breakfast could have been more substantial. Seats reasonably comfy.

I suspect that there was an item pilfered from my bag at the TAP automated check-in counter on March 26th at Heathrow Airport around 11:30am. I think that the employee assisting me with my bags took something out of it when I was not paying attention because today, March 27th there is a notebook missing. Please check the camera to see if indeed this occurred. My description: Male, African Decent, 5'8, 180lbs medium build, wearing trousers and a jacket. Employee description: Female, Indian Decent (guessing) 5'7, slight build. Flight 1359, London to Lisbon.

ABSOLUTELY THE WORST AIRLINE. LOST LUGGAGE NO CUSTOMER SERVICE. NEVER BOOK

Flight was late, economy seats are uncomfortable, and there is no entertainment. Food looked good, although I did not eat as it was Ramadan. Flight crew competent and professional. Ticket was not good value for money. Too expensive.

Improve food quality and clean the seat . Bathrooms not clean

I had pre booked gluten free as a meal preference. Nothing of that was considered during my flight. The attendant said he had no idea and would check but never returned with a response. I did not eat anything that flight and was super hungry

My luggage did not arrive yet, it been 4 days without any information

the whole flight is bad from Miami to Casablanca and from casablanca to Miami. Delays, service, food, .... Not flying again with this airline

Extremely Disappointing Experience Boarding was chaotic and poorly managed—we were left standing in the heat for 30–45 minutes with no explanation or apology. As a business class passenger, I was shocked when a staff member rudely refused to let me board after I questioned why I had to check in my carry-on, which contained valuables. Despite explaining my concerns, he remained unreasonably inflexible. Thankfully, the captain intervened and retrieved my bag personally. This same staff member was also loud and disrespectful to several other passengers. Completely unacceptable service.

This is the worst seat that I ever sat on. The length and width are great but Super uncomfortable. We felt like sitting on marble.

Old planes that are not being maintained with at least basic cleaning. Plane smells awful, bathrooms not cleaned either. Customer service probably one of the worst I have experienced.

The plane was new, clean and nice. The crew was very attentive and pleasant. The food wasn’t great, though - even in business class…
