On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

There was nothing I didn’t like, prices a little lower would help

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Qantas are unable to service and unfit for purpose, they cannot transport Australians on time to overseas destinations. On top of the inflated ticketing, the Sydney flight to Santiago was impacted because the plane was delayed arriving and then further bungling by Qantas admitting the ground new ground crew in charge of cleaning were not trained. The impact on passengers with connecting flights was tremendous and long ques of frustrated passengers waiting for rescheduling. **Qantas has become the Australian Spirit of disappointment**

I was pleasantly surprised with my flight to LA with Qantas. Although seats were not the roomies, service was excellent.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

Wonderful crew, good food. Absolutely loved the wine spritz and wish I could buy it!

Don’t like last minute airline change. Not able to choose seat earlier.

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the room where it was being kept.

The flight was delayed due to weather issue…WiFi did not work and even though I wanted to pay for WiFi I couldn’t buy it. Overall very disappointing even though I paid and reserved Business class

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

WiFi connected but only let you go to the AA website, not even text messaging worked.

Too bad that first class seats do not recline significantly causing discomfort

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Crowded plane but it flew on time and had friendly staff

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

This was the first AC flight in a long time that we experienced no delays or frustrations. The gate attendant was extremely polite and accommodating to my husband who has Parkinson’s disease which made boarding extremely stress free. Flight departed ON TIME and was a smooth ride. If only all my AC experiences could be like this.
