Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Delta is a premier airline so my expectations are most always met.

Seats are much much more comfortable than United, which is what I usually fly

Zero updates from the pilots for 30 minutes in the tarmac

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

You should not have to pay for WiFi in business class

Transfer at Amsterdam airport is very convenient and the airport is easy to navigate. Boarding was also quick and easy. Cabin crew were excellent and the meals were good, although lacking in options.

Overall very positive. Boarding was quick and organized. Cabin was clean and seats were reasonably comfortable. Cabin crew was excellent and the meals provided were also of good quality

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Transfer at CDG to connecting KLM flight to Amsterdam was a NIGHTMARE. LONG WALKWAYS, NO MOVING WALKWAYS, POOR signage, Have to take a train & No staff visible to help navigate the maze. AVOID TRANSFER AT CDG AT ALL COST.

Good flight with KLM, friendly staff. Food was good, had much worse on other airlines. Selection of drinks also good enough for us. Entertainment was also good. The economy seats are ok and that’s it. For a 12 hour flight I think a little more comfort in the economy seats in pitch and softness would be highly appreciated by the customers and can makte the difference.

Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

There was fog in Amsterdam so many flights were delayed because of the weather. Air France knew that the flight would be delayed by two hours but still boarded the plane on time. Instead of letting the passengers wait at the gate we were crammed into the plane. It was uncomfortable. No refreshments were given. I couldn’t charge my devices onboard.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

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.

More space between seats and in bathroom. I don’t think there was any entertainment offered. If there was, I wasn’t aware.

Every meal/snack included something with ham/pork - even the cookies had "swine fat" (which we only knew because we thoroughly checked the ingredients). There were no vegetarian options, and we had not been given the option of pre-selecting a meal when purchasing our tickets or checking in. That made for a VERY long flight. We were fortunate that we had brought our own snacks as back-up.

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

We paid extra for the seats with extra leg room. But we were not allocated the seats with extra leg room nor refunded the money we paid for the seats.

Very good - being handicap it was very hard for me in a center aisle bulkhead seat that Zi was assigned think it was 29-G as I had a hard time opening the entertainment screen and tray table. 30-G would have maid it easier. I was assign 29-G as it was the only handicap seat without being charged even though I was handicap (disability)

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

My flight was scheduled for about 6:05 departure. There were 11 gate changes from 4-7pm and the flight was 3 hours delayed due to operational issues. The plane taxied around the airport for about half an hour before stopping to be de-iced. It would have been nice if we were alerted of the plan to de-ice prior to the 30 minute drive around the airport. The flight attendant was friendly, which was the only redeeming thing about this flight. As a former flight attendant for United, I was extremely disappointed.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

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.

Flight was packed. This was a very uncomfortable experience. Boarding process could be explained better. Despite recommending a window seat when travelling with a pet in the cabin, the seat in front of me had less space than the center and aisle seats. For Premium Economy, the seats were crammed with minimal legroom. I hate to think what Regular Economy was like. The cabin crew missed me at first when handing out meals. When my meal eventually came, there were no utensils. I'd originally booked to fly Business Class; those seats didn't look that great either.

First time and I enjoyed the trip…. Will fly again soon 🔜

Delayed flight because other plane was occupying the gate for longer than expected. Once we boarded the plane had to wait 1 hour before taking off. We. Almost lost our connection flight and the baggage didn’t make it. We had to wait two days to receive our luggage. Hope they improve the timing or work with the airport to get better service.

I’m still missing my bags. I’m soo frustrated

TAP boarding gate agents singled out Group A line to gate check all carry on bags …. Supposedly because of lack on bin space. BUT ALL OTHERS WERE PERMITTED WITH CARRY ON BAGS. Additionally so many passengers entering the plane after us were permitted carry on bags. And when the plane was fully loaded, there was a number of open spaces in the overhead bins. I WILL SEARCH OTHER OPTIONS BEFORE FLYING TAP AGAIN

Boarding went fast. Lisbon's gates are too small for the flights they serve.

Baggage check in was very slow. No sign that the check in was TAP until the station opened. Understaffed and overworked team.

Great pilot, textbook landing in madeira. Everything else, from booking to checkin, plane quality, seat amenities, crew engagement, and overall experience were significantly below standard. I WOULD NOT FLY TAP IF THERE IS ANY OTHER OPTION.
