Gate agent did not hold flight for connection, provided no assistance to get new flight

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

United airlines, mediocre at best. No issues , nothing great . Worked for me

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

Boarding was mayhem. Late boarding by 15 minutes because of lack of staff (missing 1 flight attendant. We had to wait for an arrival of another plane before we could board). Flight was a little rough, but cannot blame on airlines.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Very comfortable (upgraded to business class). The audio on my screen didn’t work, but I managed to play the audio through my phone while watching the screen.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

They cancelled my flight and downgraded me to economy and only gave me $250 for the downgrade

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

The flight crew were friendly and attentive. Food was good and they passed out ice cream and drinks awhile after Lunch was done. The ice cream was a nice treat! I found several movies to watch during the flight. There was many movies and tv shows to choose from. We flew Premium economy and there was enough leg room to be comfortable. The seats were also comfortable. I would fly AA again if the airfare isn’t expensive.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

I’m impressed that we were on time in Sacramento after having a late departure in Newark and our made it. The staff was friendly and warm.

Cramped seats. FAA should make airlines have more legroom, for even short people complain

5.5 hour delay with no explanation on why, along with no proactive effort to reaccomodate me.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset.

Iceland airlines doesn't provide any meal on flight to and from New York, except water and soda. Airline over charge for checking in luggage. I'm really upset. If there is option to use another company, I suggest to other people use them.

I had an exit row and so was Comfortable on the long flight.

The seats on this airline are sooo small, even for a petite person. I felt like the seat tilted forward and I was fighting to stay in it. The lavatory is horribly small, with a wet floor because the sink is so small you can't help but splash the water all over when washing up.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

Smooth efficient airline. Think they should have their own bag drop as the queue took 30mins to bmscan and drop

Good. Lacking overhead bin space. No food offered but you can order online or in flight and pay for snacks.

No food was served for 7.5 hrs flight. When our flight changed to other airlines due to wether issue, our seats booked with no checked in luggage when I already payed for. We end up to pay 90 euro per suitcase.

Only serving 2 small coffee in 7.5 hrs flight with very limited choice to order food.

Booked with Kayak… Economy Class it said. I had filtered for 1 checked bag. Get to boarding and it says I have Economy Light w/ no checked bags. $136 each way for baggage now. Do not use smartfares.com. Very misleading and a terrible start to this trip.

You get what you pay for. In general I like the service and flight attendants.

Excellent! Outstanding customer service, the best service I have received. Food was served, dinner, snacks, beverages, crew was there to greet you. 10/10

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

My carry-on bag was taken from me when I boarded. It was checked through to London at no charge. It took a big of shuffling, but I was glad not to need to mind it until baggage claim.

Great to have power available for every seat in Premium Economy. I do wish the WiFi was less expensive. It was 23-24 Euros for the flight for one device. And there were times it was unavailable.

I’m very mad because I paid an extra $105 to change seats to an exit row with more leg room. The app clearly showed a gap in between the seats in the row I changed my seat to and I paid for it. When I boarded the plane, it wasn’t an exit row seat and no more room than my original seat. I feel like I was ripped off $105.

The crew on AA international flights in my experience are generally lazy, rude, and inefficient. These guys did not disappoint.

I had a great experience , crew was great and enjoyed the entertainment options I will be booking my next International trip with them .

Front desk was closed at 6 pm, I was unable to get my boarding pass and as such missed my connecting flight home.

I wish they could put the pre-tsa check on the tickets or global entry.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Boarding was fairly chaotic. One of your employees clipped my ankle as he was passing with an empty wheelchair and not only did not apologize but stated something to the effect of “oh forGod’s sake.” There was plenty of room for him to pass. otherwise, everything was excellent.

Fantastic! Great seats! Friendly staff! Amazing selection of shows and movies! Smooth ride! I don’t know what more I could have asked for honestly. They made flying a breeze this time around.
