Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

The boarding was horrible. You couldn’t hear the announcements at all. Probably because there is so much in the area for businesses. They need a louder PA system. Other than that it was a good Delta experience.

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

On 2 different flights the wifi was horrible and there was no drink or snack service.

The pilot was excellent - he flew us around a storm and even though predicted it would be a bumpy ride - was able to avoid all turbulence and land us safely with only a 15 min delay. Kudos!

Great flight crew, easy boarding, delicious snacks and spacious seats. Love flying delta - worth the price.

There was no FREE wi-fi nor entertainment screens at all.

Delay at gate caused a flight change for our connection, hotel stay, and lots of standing and waiting in lines which hurt my feet and was unpleasant as people were grumpy and yelling. Delta worker Nestor Espinosa was very helpful! Others were apathetic (tired I’m sure!) but weren’t clear with instructions and didn’t give both of me and my travel partner the same food voucher etc.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

From boarding to the next 45 min to 1 hour, it felt like a sauna, felt like vents were working but no AC on.

If the flight is delayed, get the delay timing right and don’t have people standing in line ready to board for almost 2 hours because you keep pushing it back. Also, don’t have your flight crew say they are sorry when they clearly don’t care, make no efforts to speed up anything and then turn around and are rude to customers when they don’t “move fast enough” to put up tray tables and seat backs.

I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

I really do not like the basic in basic economy.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

28 hour delay at Fort Worth/Dallas airport, part due to weather which was unavoidable, but various other reasons - no pilot, no fa, mechanical problem, plane too small, too big, crew out of flying time, seat configuration problems.... endless and hourly updates with a different excuse. Finally told us about 3.00 am, that the flight was delayed to hours later.

Experience was bad. 3.5 hour delay for a 2.5 hour trip. There was no r Transparency about the reason for the delay and it was done 30 mins at a time.

We were redirected to a near by city due to weather and had to stay in the aircraft before flying to the original destination's airport. The whole delay added 3+ hours and were were not offered any snacks or water.

Both flights yesterday, experienced hard landings. Harder than I’ve ever felt before. Im hopeful there was weather involved and not pilot error. Other than the landing, the flight was quite good~

The flight was 90 minutes long and the stewardesses were extremely slow. I was in row 16 and they did not serve us drinks until we were descending for landing in a 90 minute flight. Unacceptably slow and at least 10 rows (20 to 31) did not receive any drinks or snacks for the entire duration of the flight because of the slowness of the stewardesses. There is no rationale to delay beverage service to brew coffee for a flight at six p m.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

Couldn’t use car seat due to lack of window seats available was disappointing

Best price with timings that suited us. The flight was punctual.

After my luggage was grabbed by another passenger, by accident, I chose to speak with the American Airlines staff within the airport. Not only was the customer support staff uninformed but also very argumentative, making this situation harder to deal with. I was only able to finally retrieve my luggage thanks to the passenger who took it contacting me due to the tags on the luggage. All of this was happening during another 2 hour delay and 3 gate changes. Horrible airline with disgusting, on the ground, customer support staff.

The experience with American Airlines was terrible from beginning to end. Flight 1210 from Cancun to Charlotte was delayed three times. AA customer service at the CUN airport could not provide information on why or how to accommodate me if I missed my connecting flight at CLT due to the delays. Upon arrival to CLT, de-boarding the plane was a horrible experience. You all should have allowed passengers with departing connecting flights within the hour, to get off the plane first! It caused so many passengers to lose valuable time waiting to get off the plane, and then the long lines in customs! American Airlines knew passengers had to make connecting flights and still chose not to hold the plane? I missed Flight 2758 from CLT to DCA for that reason. Waiting three more hours for the next - Flight 1269 from CLT to DCA. Once again another delay at the last possible minute before boarding due to the plane going out of service/maintenance. Once the new plane boarded, we sat on the tarmac for 40min. I did not arrive to DCA until 12:33am. I spent over 12hours at the airport and I plan to never fly American Airlines again.

It was delayed 9 hours for operational reasons, despite the plane arriving to the airport on time.

I am very disappointed with Frontier Airlines. They cancelled our flight because they couldn't find a crew member, and then didn't get us to our connecting flight. We had to cancel our whole vacation. We were promised flight and hotel vouchers, but they never sent them.

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

It was ridiculously hard to check in for the flight, and Frontier charged us a LOT of money to have a carry on suitcase, and then told everyone we could not carry on bags and had to check them through at the gate, and didn't refund the extra money we paid to have the suitcase as carry on.

I had a terrible experience with Frontier. I arrived before the 60 minute cut off and was told that Frontier has a two hour window for bags. I was then told the next available flight wasn’t until the end of the day (I had booked a 6am flight). I took a look around and saw other people being told that they could not board their flights or that they had to pay additional fees. I opted to rebook on American Airlines. There’s absolutely no straightforward way to contact Frontier, so this ticket was a complete waste of money. Oh - and the kicker is that the lady lied about the two hour cut off.

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

Worst experience I have seen. The flight was cancelled without any reason.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

The Frontier app wasn’t working. So I could not pay for a carry on the week prior to flying. They charged me 99$ at the gate to carry on a duffle bag.

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.
