I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

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.

Waited in line for hours just to get a boarding pass which would not print at the kiosk or load on my iPhone. Waiting again for about 45 minutes to get through passport control. Poorly managed airport. The flight and crew were great and the flight was very comfortable.

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.

Our flight was canceled for a reason that suggests gross mismanagement. We were re-booked for a flight to a different airport.

Worst: long walk to baggage claim Best: left on time

The flight schedules are better than some airlines. Their website is terrible, it doesn’t store any information so every time you fly you have to re-enter the data. The flight was late taking off but we still got to our destination on time.

Great overall experience with TAP - would not hesitate to recommend for your next trip to or from Portugal

Correct meal and overall flight went well. 204€ for an extra luggage is simply exaggerated

Bused out to the plane, then back to the terminal. Plane was delayed for 2 hours - most of that time spent sitting in bus or plane with NO EXPLANATION of what was going on. Departure delay due to crew not showing up on time. FIX THAT. Why do your own international flights NOT have gates with ramps. Being 74 and having to carry my carry ons up and downstairs is awful.

Boarding the plane from 2 entries at the the same time front and back was ridiculous. I boarded from the back for row 7 and others boarded from the front for row 15, for example. We met mid-plane and had to squeeze past each other. Ridiculous

The flight was cancelled. the staff did not know how to arrange overnight, food and transportation accommodations required by law, causing long lines lasting several hours. the rebooked flight was then delayed 5 times from 9am to 4:45pm

Cancelled flight TP225 from LIS to MIA till next day

The connection required us to travel from terminal A to terminal E with very little time in between flights. While waiting in line, we were called to the service desk to provide our passports. We provided our passports at time of check in, assuming that American Airlines doesn’t communicate well with Iberia, this was a headache.

The staff on our flight from Charlotte to Boston were very friendly.

Alaska located my mother, aware that she had mobility issues and they seated her closer to the door. She and I were seated together so I felt more secure to be able to assist her. The desk attendant reviewed what steps to take when boarding. Allowed us to board first, we loved that. I was allowed time to help her board slowly, seat her, put all her things in their place before the crowds came through. These small details made me want to travel Alaska more when possible.

HORRIBLE. 3 hours delayed. Crew did not communicate properly and was rude to passengers enquiring. Delay caused multiple passengers to miss connections.

1. The flight was late and I did jot get the seat I paid for. I paid for extra leg room and a window seat. I got a middle seat without extra leg room. 2. The customer service representative was not helpful. Explanation: many passengers arrived to the service desk in Madrid near baggage claim to rebook our flights. (We all missed our connecting flight due to delays in JFK). Upon arrival, ghere was one service agent and one line-business. After about 25-30 minutes the agent left and we could see her making a phone call. After about 5 more minutes, 2 other agents arrived. During our wait, another line formed for main cabin customers. We were told to go to the other line, even after waiting around 30-40 minutes. This would have been disastrous for ghose of us who had been waiting for so long. The agents need more training.

I fly to BNA with BA often and this was the worst experience. Arriving in nashville, check in was 1.5 hrs long in the queue with 1 very slow girl at the desk. When more staff came they only catered to priority customers. When all priority were checked in, instead of filtering from the top of the line they took the people from the end, the people who had been queuing for 5 mins vs almost 2 hours. The flight was delayed, for no good reason other than the staff took forever to do anything. At the gate there was zero organisation, we asked the crew what the delay was and they confirmed it wasn't the plane and it was the ground team. One of the flight attendants was one of the rudest I have EVER encountered, that man clearly hated his job, and people...I wish I'd got his name. Food was disgusting, seating was cramped. I've no idea what's changed in the last year but I'm truly shocked.

Booked Economy Premium the 3 seats with my daughters and I, the seats should have been able to tilt back but it only one worked. the crew said they would report it but didnt seem both about our comfort on the return journey.#

Better pillow cases in economy. I didn’t like that I couldn’t pick my seats since I booked with Kayak.

Room between seats unacceptable. If person front of you dropped down there seat even a little you could not be even a little comfortable. No sleep on flight

A bit noisy. The seat was suboptimal and there was too much noise in the service area. Some if the crew members were less than nice; others were great.
