Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

I buy ticket from you and when I go to the airport aer Lingus they tell me you need travel visa for Ireland for one hour travel so when I buy tickets there no requirement I need transit, visa or not so when I try to cancel my ticket or change my ticket, you guys say there is no refund so you u guys take all my money which is very disappointed

The aircraft was clean and relatively comfortable- for an aircraft seat. The entertainment was good. The food was terrible, especially the “breakfast “ which was a cereal bar, and just not good. The crew were amazing, professional and no complaints there. The food was so bad, I know for my return, it will be inedible.

The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

Flight crew was superb. Meal was one of the meals at altitude I’ve had

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

Excellent flight and crew. Boarding at Dublin Airport was a very difficult trying to find the right gate.

Delightful flight, ahead of time with a super crew, thanks

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

The plane was FABULOUS. The crew were wonderful and the food more than I expected.

The food was dry and tasteless. Boarding process was ridiculous. Lounge is Lisbon was of very poor quality. The website is nearly unusable. Customer service was challenging. This was my first transatlantic business class flight with TAP. There will not be another.

Disappointing Compared to other airlines , this one was the most expensive. But not even close, in getting what you paid for.

Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

The seats were not designed to comfortably see people in coach for more than 10 minutes

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Everything went very well. I would like to acknowledge the politeness and professionalism of the staff—they are superb. No complaints.

No legroom, have to pay for everything including water?!? Water is more expensive than beer?

We liked the crew. They were competent, professional and friendly. The only big negative was our departure was delayed several times and the airport staff did not communicate what the problems were and what we should expect.
