They charged us 100 Euro per bag on the return leg with no explanation.

Everything was perfect, clean and very nice staff. But the seat was uncomfortable compared to other companies and the food wasnt good

Flight wasn’t full so got to stretch out and sleep.

Boarding was delayed. Then when we queued, it took us to another long line to stand in. Flight had 0 entertainment. Not even a magazine. But they had a free meal and it was good!

You cannot add an additional luggage via the check in. It seems to be an issue with Azore Airline.

The facilities at PDL are absolutely appalling during a 4.5-hour connection. Passengers from multiple flights were crammed into a small area with insufficient seating and only a snack bar. The only bathroom was unisex, with one stall for men and another for women side by side. This is for hundreds of passengers. The connecting aircraft from PDL to JFK was downgraded/switched out to an Economy Class-only configuration without explanation, even though the aircraft with Comfort Class we arrived from FNC on remained at the stand. Those who paid for Comfort Class could not enjoy the better seating or catering. Food and drink aboard was sub-par. I would qualify it as one of our worst travel experiences in years.

The crew was great. The only problem is that electrical outlets were not working in what seems to be a half of the rows on the plane. Considering that passengers are asked not to use power banks, this leaves us out in the blue without any entertainment option.

Reasonably comfortable. We were about an half an hour late. But no personal impact. Seats upfront have a good amount of recline, but do not lay down flat. Food and drink can be improved. There are no soft drinks available on the flights. Water, juices, and wines are provisioned.

Flight on time. Staff pleasant and responsive. Food could be much better. Snack before landing was a few dry crackers and a drink. Nothing else. There was a very lumited selection of beverages available on a 7 hour flight. No soft drinks, even in the front cabin.

Delayed departure of one hour and half, inflight entertainment NOT functioning. Plane did not crash and I arrived alive, so I guess it was a good flight.

Great price for really nice seats and the plane and staff were great, only 5-10 minute delays!

Tap was very frustrating in Lisbon. Not enough direction and help. Mixed messages of where we needed to go. Seats were not very comfortable.

Everything went as expected. Luggage arrived at my same destination and nothing disturbed my vacation.

This flight arrived late. We joined well over a thousand of other people waiting to go through customs. Air Portugal has lost my bag. We had to chase down a representative even though we had waited at the baggage claim for well over 1 hour and 35 minutes for baggage to come. No representative was there to explain the delay or to give any direction. After 1 hour and 35 minutes at least four passengers had no baggage to pick up or had a fraction of their baggage. The representative was a young woman who clearly did not have the experience to deal with what was happening. Very disappointing as of course we were dealing with great amount of jet lag and having been up for 24 hours at that point and not being able to have any of the things necessary at home that were contained in the bag was quite upsetting. That instant occurred last night at approximately 11:15 p.m. and as of 12:30 p.m. the next day I have not heard anything from Air Portugal.

Check-in guidance for transfer flight, boarding, in-flight service, seat comfort, etc.

Very rude person at the boarding desk; flight attendant coughing 3 inches from my face three times- not even covering her mouth; boarding process very unacceptable for older people with stairs to all planes (are you all stuck in the 1960’s?). I am sure that I am not remembering all of the negative things, but I am sure you get the message!

Flight was fine. Second meal ( fish sandwich on hard roll) was awful. My suitcase didn’t make the flight. It had been located, but won’t be delivered until tomorrow. Five days after flight

Boarding experience was awful. TAP claims I did not have check in luggage with tickets. I went 3-4 check in agents until I finally found a helpful kind agent who checked in my luggage with no fees. On top of that our flight was over 2 hours delayed with barely an apology or explanation.

The airport temperature at the airport and on the flight was too warm

Flight being delayed for 35 minutes had me lose the connection to my transport
