Delayed for three hours. This seems to be CAL’s MO when flights aren’t filled until they fill it. Business class is nice but not luxe like other airlines. Lots of space and amazing staff.

Boarding the flight was smooth and the flight was not full so i had an extra seat essentially

There was no flight. They canceled the flight with no knowledge to me, and I still haven’t received a refund

The flight was delayed over a hour and that was over 15 hours in advance not good

At check in I had to pay for my seat that I already paid for on purchasing my ticket. The flight was over an hour late and the plane smelt gross.

Flight time. The crew was the rudest, talked down to customers, ignored requests, acted like security guards, used forceful language like must and can't. Everything was on purchase, no entertainment, unless you could use your own phone. Poor customer service.

The flight could'nt be better ,the comfort ,the crew and everything was good.i will definitely fly with this sirline again.

I love my entire experience. What I love most, was the friendliness and helpfulness of the staff at check-in and that of the crew on the flight. Their Customer Service was paramount.

The flight crew was extremely hospitable, though there was a lot of turbulence, they made it a good experience. The only negative was the inflight experience for economy class. There wasn’t any, or at least non that I was aware of.

STEWARDESSES WERE AWESOME! The food could be a bit better. Rice was SOGGY with gravy and the chicken was RUBBERY.

Comfortable seats. Nice service online. Short flight, so not a lot of time to enjoy.

Awful. There was an unexpected delay of nearly three hours because there were not enough flight attendants. I understand this is likely due to FAA regulations; but in that case, Delta should coordinate with smaller airports such as RDU to have extra flight attendants on the ground and "on call". In addition, this was the second 2-hour+ delay to Boston on this route in one week.

It was strange that the flight attendant was so adamant about having phones turned to airplane mode that he was calling out names from networks shown and waiting until they were all gone. I've never experienced that before, and after already working through an hour+ delay, it felt tone deaf. I take dozens of flights per year and have never experienced anything similar.

The flight was done by SkyWest only WIFI no entertainment center are available on the CRJ

Your survey needs a N/A option. I didn’t use the entertainment or eat food.

The flight was over 2 hours late.. once we finally got boarded things were fine

Poor communication, we sat on the plane for an hour before pushing back. They were oversold and with a full plane kept looking for someone to step off for someone else to board. So after an hour wait at the gate we missed our departure window and proceeded to spend an additional hour on the tarmac waiting for a refiled flight plan according to the pilots. Occasional updates, somewhat insensitive crew to passengers needing to use the lavatory (it was 2 hrs beyond what anyone expected). Overall just poor execution...especially when the flight was listed as "arriving early" up until about 30 minutes past our departure time.

No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

Flight was delayed for about an hour but overall good experience

Staff is friendly and helpful but flight was delayed by one hour from Detroit, making for tight window in Toronto to clear Canada Customs and pass through security screening in order to get to connecting flight on time.

The flight crew were very helpful. The seats were very close together. There was barely room to sit without touching the person next to you.

I’m an EP on AA every year for more than a decade but this was a very pleasant and surprising experience. Clean and sizable plane for HOU to CHI. 5 row first class. And excellent food in first class the steak option was really good. Your flight attendants even better. Seat 5A

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

My flight was delayed so bad i missed u it so i just said never mind

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

Gluten free snack options and meals that offer both gluten free and dairy free.

The pilot was late so we didn’t take off til almost 2 hours late.

The SFO lounge closes at 12 midnight. My flight took off at 2AM

Not a bad flight but a long delay boarding and taking off due to the pilot not arriving on time.

The experience with United Airlines was excellent; however, the experience with Houston Intercontinental Airport (IAH) was horrible. Although our flight departed from Terminal B, we had to go through security in Terminal C and then get on a train for travel to Terminal B. Additionally, there was significant walking required to get to the boarding location.

This flight 1810 on 7/30 from EWR to DFW got 4 hours delay. this round trip experience is bad, my AA flight 618 from DFW to EWR on 7/28 was redirected to PIT and totally delayed about 9 hours due to mixed of weather and AA IT outage and then on the way back delayed for 4 hours. Lucky, i changed my flight to UA on the way back. i don't like AA anymore. i will consider other airline options in the future.

Bad experience going to DFW with an IT outage then bad on the way back with a nearly 5 hour delay that’s started as maintenance then caused us to wait further due to weather - which would not have happened if we had left on time.

IT issues created a mess had you change my flight and your system never changed it

Horrible experience flying with American. Flight was delayed due to inbound flight delay. Fine, it happens. Then, we were delayed an additional almost 30 minutes due to the paperwork for departure having a "clerical error." Then, upon landing at the destination airport we were stuck on the plane for an HOUR after we landed and pulled up to the gate because apparently there was another plane. An hour waiting for the gate 12:30 AM when the flight has already been delayed due to operational error feels like a complete failure of the ability to do the one thing they need to do apart from actually have the plane takeoff and land. Very disappointing.

It was a 3 hour flight from Dallas to Missoula. The aircraft did not have power plugs, internet or in-flight entertainment. When boarding, one flight attendant was "somewhere in the airport" so delayed the boarding process (not coming from another flight) although we did take off on time and landed early. In flight there was little to no service - we got the standard beverage but no real connection with the crew which feels unusual for a 3 hour flight. A passenger needed help stowing her bag and got no assistance, and actually some passive aggressive comments from the flight attendants about "she needs to remove the extender" and "she'll have to find a place for it". I have seen others be helpful and put a bag in the closet, or support assistance as the boarding door was already closed. Just not a great experience considering the cost of my round trip ticket {$1000}.

Disorganized boarding. Mandatory to gate check bags. Curt flight staff. No space for cabin bag, even when I was in first class.

On time departure & early arrival. Made a long day much better.

The ground closures and flight delays were unwelcome. I think the captain did what he could to manage expectations for the delays, but the stress level increasing in the cabin was palpable with every announcement. It may be obvious to those who fly frequently, but if the ground is closed for us to get to a gate, it's also closed for connecting flights to leave. Other passengers were so stressed they were rude. A bit further explanation could have helped.

Horrible. No AC. No Air inside the plane. We had to deplane twice! It is late almost 5 hrs in total. I almost passed out and about to call 911. I asked the crew to be honest and open the door. The lady next to me was lay down in the floor due to heat and no air inside the plane. I got headaches, can’t wait the replacement flight about midnight Dallas time. I end it up rebook for next day flight and stay overnight using my own pocket in a hotel nearby due to headaches and can’t breath. I still have a headache this morning. Still not decided yes how to file this issue to AA and/or FAA.

They have overselled the ticket and kicked me out from boarding, All my Plans were collapsed and important network meeting missed.also I booked direct flight i have to go through an 1 stop and it was frustrated.

Everything was good except checking bags . I had paid for two bags but it didn’t show so we had to do it again while people waited and we were struggling to get to our flight

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The seats were roomier than other airplanes I’ve been on.

The crew and the pilots. The pilots were amazing. The landing in Cancun was excellent.

The security line at JFK was one of the longest I’ve ever experienced - probably 45 minutes. I don’t know if JetBlue has control over it, but it detracted from the overall experience. Entertainment had good options, but the volume control was a bit small to tap on and the screen had a fair amount of interference blips. Clearer picture would have been better.

I liked the entertainment on JetBlue, the service from JFK to JAX was terrible at best

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

The flight was delayed. I upgraded to more room. I can't imagine how small the regular seats are I haven't upgraded for my return flight yet.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.
