The value is there, but the layovers in Lisbon were not great. The passport control was so bad that a 2 hour layover became very tight and on the return the Terminal was barebones which made it a long 3 hours.

The value is there, but the layovers in Lisbon were not great. The passport control was so bad that a 2 hour layover became very tight and on the return the Terminal was barebones which made it a long 3 hours.

Plane was delayed, reading the gates on their screens was horrible. They posted it a half an hour before the plane boarded. By the time I got there with my premier boarding they have filled the plane because it was over booked. Gate closed at 12:03 I was there at 11:54 plane took over around 12:20. I was told they would put me on the next flight. I had to go to TAP information desk. They didn’t give me a voucher they just said they would put me on the next flight. At the desk I was told I had to punches a ticket. The woman said buy it online because it’s cheaper. It in fact was not cheaper. But I had gotten out of the long line that formed so I paid 200$ for a new ticket. At a later flight, not the next flight. I had checked my bag and was told it would be on my new flight. I was then bumped to an earlier flight and was told my bag would also be on my flight. After landing in Madrid loosing a day in my hotel i landed without my bag. They didn’t load it on any flight that day. It arrived in madrid the next day. Essentially ruining the first two days of my vacation. I’m now seeking compensation.

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.

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.

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.

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.
