Bring a variety of snacks in case customs and TSA take too long and can’t buy food if you are connecting. Very busy lines.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

It was Delta, but the flight attendants were stressful and disrespectful. I am a diamond member a travel weekly. I have not had a negative thing to share in quite some time. But this was noticeable.

Comfort Plus seat 11E seemed smaller than prior flights. The movie selection is good. Watched most of the most recent Tron movie. I'll watch the remaining part later as my movie is saved in the Delta Seatback Experience.

Flight was late from Newark to Atlanta, I asked flight attendant to please let my family of 3 out first when we landed to Atlanta because we were late for our connecting flight to Quito. She didn't and we were late for 5 minutes we couldn't board the plane and spend hours trying to get another flight with customer service for the next day.

I really liked the legroom. I am 6’4”.a at For some reason our seats were not together and using the app to fix it didn’t work. Passengers were nice enough to move for us but you should absolutely ensure a parent sits with their child.

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

DTW line is too long. The flights from DTW to BWI are always delayed for unknown reasons.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

A 12 hour flight during the day with one real meal service - are you kidding? Also the breakfast was one of the worst and not what was listed

Unbelievably poor service from flight attendants. They didn’t even do water service on a four hour flight. Just disrespectful.

Seats had less pitch than a regional jet. Food was OK. Have to buy alcohol on US based carriers flying international. Boarding was a mess. Did not have bags but overhead space was gone quick. Would like to see the airlines enforce the one bag over and one bag under policy

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Crew was excellent. This was a relatively long flight though and had very little leg room, and no entertainment.

The newer screen was super cool and had the option to watch many different shows or movies. Crew was polite and helpful. However again, many children screaming bloody murder and kicking my seat, and parents doing nothing about it as usual.

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight was delayed and missed my connection Lufthansa didn’t respond.

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

United could have one single once of customer service. No human United employee would help me with the invalid mileage plus number, they said I had to speak with the computer.

Overall it was good. I missed my connection but I was put on another flight.

Seats were much more cramped then on the 737. Narrower and rows closer together. Flight was absolutely packed and the plugs under the seats didn't work. Was forced to check my bag even though previous flight had no issue with it.

Good food & refreshment. The seats and entrainment screens are modern compared to others. The staff though pleasant serve and attend to passengers based on nationality. Some get served first others last regardless of their seating positions.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

We never made it due to delays on both ends. Gate attendant said it was mechanical but the system said otherwise, so no compensation. That’s not right.

The pilot greased the landing and the crew was fantastic.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Attendants were pleasant and the flight was smooth and relaxed.

It was fine. No drinks nor snacks offered though. I thought that was unusual.

Things were delayed a little. But that didn’t affect my plans. It was fine. I was surprised it was so full thanksgiving day. The crew were friendly and professional.

The flight was delayed multiple times, again no fault of American but again the extra cost, for everything makes it feel like a cheap airline! Especially when flights are outrageously expensive already

Flight was canceled for a reason they knew hours before but did not mention. Next the gate chnage from 37 to 38 at least 10 times. Ridiculous.

It was just fine. I managed to make all my connection too sbut had trouble in Munich with no wheel chair and trouble trying to get help from the airport people to get to the other terminal for my flight. Finally a wonderful lady Amelia, helped me to make my flight connection Timon with zero time to spare.

Super experience. Earlier than schedule departure and arrival. Baggage handling was very good

I would like to get my money back. I flight was 4 hours late on the way to detroit, And same on my way back to Brussels they cancelled my flight and give me an other ticket and i had to wait 5 hours.

All attendents were very efficient, pleasant and happy. Everything went smoothly. The seats could have been wider. There could have been more free food instead of just one small bar.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

Elderly female flight attendant was not customer friendly. There were only about 12 people on a regional jet that had about 60 seats. There were 8 exit row seats and none of them were taken. We attempted to sit in those seats and the flight attendant gave the standard " you didn't pay for those" so she would not allow us to move. What harm would that have caused ? They assigned seats to 5 of the 12 people in 2 rows, row 20 and 21. A simple friendly customer experience gesture of allowing us to sit in exit rows would have gone a long way in me having a very favorable impression on Air Canada. After that I have very poor impression of Air Canada and will not fly with them when I can avoid it.

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

Almost everything it was a “cool” ambiance but we arrived to Toronto so that it’s ok for me
