Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

Delta is one of the best airlines I have flown

They did a fine job. Can't wait to use Delta in the future.

Flight delayed about 2 hrs so it made it a VERY late night

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

Crew were exceptional. Plane was quiet and quite empty, so I had a row to sleep across.

The seat could use more support or cushion. I'm in my 50's and have back issues so the seats are a bit hard for longer flights.

The plane was in bad condition. We were taxied for mode than an hour because a light panel had feel off. The bathroom in first class had broken panels as well. Overall poor aircraft maintenance

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

The overall flight went well and the aircrew was pleasant.

Very comfortable Prem economy seats for a long haul flight. Had a problem with the tv that the crew fixed so was great!

Cathay Pacific seems to be an airline in trouble and on its way out. Lots of broken or poorly functioning things like entertainment screens, seats, and enough well trained staff to handle a full flight. Sad...

The flight crew was exceptionally good. Personal needs were well met. The food choices were very nice.

Excellent. Planes are a little older and could get some refurbishment, but besides that everything was excellent.

While I was in great pain, the seat was sufficiently comfortable to allow me to rest and not be in so much pain.

we were upgraded which was a blessing and tender mercy for us. I fell the day before and was in extreme pain from knee to shoulder. Sitting in a more comfortable seat during the flight was an unexpected blessing and experience.

Seats were very comfortable. Crew were excellent. Food very good.

Flight crew was especially thoughtful and attentive, made sure our seats were comfortable so we could rest on the long flight

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

ticketing issues caused many customers to have to go back to check in after waiting in security, then go through security line again.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

Despite a bumpy flight the pilot was great. The rest of the crew on the other hand couldn’t care less if a passenger would colapse and die. Horrible service, robot like, lifeless…

No service due to turbulence. No entertainment on this type of aircraft. But nice old comfortable seats.

Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours

Great service, on time, professional experience. Great landing under challenging crosswind conditions at BWI. I made my connection in Charlotte despite the plane getting stuck finding a gate to park in on arrival. The only glitch -- the Airbus 320 from CLT to BWI was quite comfortable, but the larger 321 from Logan to Charlotte had minimal leg/knee room. I get that it's a high volume route but dang, couldn't even open my laptop it was so tight

Very smooth for one of the busiest travel days of the year and the crew was great.

Uncomfortable plane, no entertainment and to board they had us standing in a line for over 20-30 minutes

Flight was delayed twice then cancelled. We were never notified of a new booking.

Flight delayed then canceled! I will NEVER fly Spirit Airlines again and will tell all my friends!

Absolutely terrible. The boarding process had zero organization. Mobs of people trying to board. People were climbing over my child's stroller with her in it. No families were boarded first. Boarding was delayed with no reasoning or notification that it would be late. We were then stuck on the plane for 45 minutes after landing. Then waited over two hours for our luggage. There was zero communication with the travelers. Never have I experienced such I professionalism and disgrace of others. Extremely disappointed.

For it to have left on time! Instead of two hours early with zero notice

Flight kept delayed from morning to late afternoon so I had to make other arrangements

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

Everything was really good but the seats are not very comfortable.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.
