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

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.

This was a long flight - 6 hours - and nothing is truly comfortable for that long... but the flight crew was friendly and attentive. The airport in the Azores is small but we weren't there long enough to explore any amenities.

There is one flight a day and it was canceled with no explanation

Flight was ok. Food on way there great a pork dish way back tuna and pasta was not good. Flight attendants were great. Wish they had more soda options like ginger ale seltzer water. Good experience overall. Worst part of trip was car rental Klass company car broke down we were on side of road late night 4 hours awful awful experience all they wanted was 500 euros for help to come absolutely horrible experience we were scared side of highway they offered zero help!

Coming from USA it was nice to be treated nice for a change. Even though our flight was pretty short we were served breakfast. On time flight with very caring staff. Please teach American carriers how to treat people.

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

Was the best airplane ✈️ ever that I never see I will traveling again again with u guys.

Flight was delayed on 6/20 to miss international connection. Next flight out was 24 hours later. Not acceptable.

Flight from FNC to OBO was cancelled. We were rebooked to Lisbon later in the day. It was inconvenient but it worked out ok in the end.

Terrible flight attendant attitude. Average 3-star hotel employee has better hospitality skills. Business class seats are literally a joke. TAP executives should ride business class in other airlines to develop some rudimentary sense of what business class is.
