I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

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

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.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

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

My only real complaint was how much turbulence there was-and that probably can't be avoided. I felt really sick getting off the plane. But boarding was super easy, the flight attendants were friendly, the bathroom was clean. Everything else about the flight was perfectly fine. Thanks!

Caroline (Supervisor) was great! Salute to the employees like her!

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.

Everything went smooth. All flights were on time No changing gates, . No changing flights . It was like a completely different airlines tha n the last time I used Cathay Pacific . The last flight, 2 months ago, I had before this one was from Philippines also . I got changed in Manila and was told it only added 2 hours onto my flight . My 20 hour return trip ended up being 30 hours return with a 10.0 hour layover in New York with no seats anywhere . Everyone was sleeping or sitting on the floor . Unlike the hotel I was given in Manila to wait for this flight home . I never thought I would use Cathay Pacific again . But I did and this time you were great! I should have complained about the flight and layover from Hell a couple months ago. Consider that I am complaining about that august/23 flight now . Thank you got the great flying experience on my way home from philippines .

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.

Because I can’t stand very long in one place, I was allowed to reword.

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…

Flight to Phoenix was delayed 1 hour and was not weather related. Flight Denver was delayed 2.5 hours and again was not weather related as the plane came from San Francisco.

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

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

I don’t think I should have to pay for extra legroom because I’m a tall person I had to get the extra legroom for comfort that shouldn’t be the case. I should be penalized by the airlines for being a tall person..

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 was delayed 4 hours for no reason given. We were not updated. We were not given any food or drink. We were not offered any compensation.

Not much seat room, but that was unexpected. But the seat headrest was very uncomfortable.

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.

They dont really bother you about carry-on size, I brought a descent sized backpack and they didnt even check.

Spirit canceled the flight in March and never notified me!

Seats suck, not enough room, overcrowded planes, hectic situation all together.

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

Delayed..4 times...completely disorganized boarding. After 5 hours they scrambled to move ppl off plane bc they overbooked. Then they didn't have a cabin crew. WiFi on plane didn't work. Zero amenities. Once we boarded we sat on tarmac for an hour. Explore all alternate options including purchasing a pair of hiking boots and walking to your destination instead of flying spirit.

what I like about Spirit is that the pilot and crew are good communicators. The plane itself - well, its a budget airline and you get what is expected, But I generally just feel safer, somehow, when I know more about what is going on - and Spirit has always done a good job of telling me what is going on: why the delay, why the turbulence, why this and that... and that means a lot to me.
