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Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Never nice, United Express partners always do an amazing job.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

United ground crew and pilots are friendly. The in-flight staff (flight attendants) are the worst in the world. Multiple trips, always unpleasant, combative, use implicit threats to not allow for a discussion on their decision. Authoritarian. This seems to stem from an internal corporate wide policy as I doubt that United is intentionally searching for people that are not fit for customer facing positions. I will not fly United again. Good luck fixing your business

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?

It was as expected for such a short flight. No complaints

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

Packed commercial flight was as comfortable as can be expected

My seat was very worn. Otherwise I had an excellent flight

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

On time (actually a little early). Was a good and short flight!

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

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

I was in Business Class row 7 on a 787-9. Both times I didn't get my choice of food. Otherwise, excellent!

Problem with operation of on board entertainment computer. Failed about 1 /2 hour into the flight. Rebooting failed to restore.

Putting carryone size suitcase into the overhead luggage storage on a the small CR900 plane was cumbersome and its assignment to a far far gate w/o the moveable ramps at YYZ arrivals really stunk.

This flight was a lot more comfortable with more room than the Air Canada Rouge!!! We will never go rouge again! A yes to this one!!! It was so nice to have inflight entertainment! Also the carts came around twice for drinks or a snack!! Great experience all around!

AC flight attendants aren't overly friendly. Otherwise flight was fine.

Newark to Montreal was really good. The return flight was not so good with a substitute carrier was not as good. I was impressed by the AC staff all along the way. Their in flight stack was superior.

I’m handicapped and the staff and crew were so kind and helped me board and made sure I was fine during the flight.
