Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

Flight was delayed by 2 hours, meaning that a flight to Dwnver which should have arrived at 11pm came into the airport at 1 am. Made for a very long day.

Flight was constantly delayed with significant changes in time, it was supposed to get to Colorado Springs at 8:30 PM but it got there after midnight.

I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

My experience was find with Southwest. The only issue I have is...at the exact time for me to check in...I don't understand how I always end up in C.

Very helpful, convenient, nice crew members, no extra fees, helped us saving 4 hrs of travel by booking is on an earlier flight

Our first flight was so delayed that we had 10 mins to board the next one. We requested if the flight attendant could allow us off there plane first and they denied our request even though I have seen this done before. Luck was on our side that we didn’t miss our next flight.

It was a very good experience. No major issues at all.

Lost my bags with all my ski gear and only gave me $500 to get new gear. They don't even know where my bags are. I was stuck in Denver airport from 10am yesterday until 12pm today and then stuck in Hayden airport for 3 hours waiting to find out where my bags are.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Boarded early, left early, arrived 40 mins early! A win win for me!

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

On the return flight, arriving in Denver we sat on the tarmac in Denver for over 20 minutes.

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Was as expected. Good leg room on planes - much appreciated.

I know that there is nothing than can be done about rude customers. I did find a couple of them were very rude and inconsiderate In my case the guy who was sitting in the same row as I was in, was trying to watch a movie with no headphones, a crew member did ask him to turn it down or off (thumbs up for that.) Another thing, as we were about to land another young man must have taken his phone off airplane mode was talking with his friends and using fowl language which I found inappropriate to the ppl who were sitting in the same row as him and other ppl around him. I understand how no one wanted to address this person and not get involved. We all just wanted to get home safely with out any incident.

The food service was limited and not good. For a seven hour flight they could do better.

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

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.

Horrible - for the first time in my life i was denied boarding an international flight because the name used on my ticket - Josh - was not exactly the same as my passport - Joshua. At no time during ticketing, online check-in, or at the airport flying from Boston to NY was i notified of a problem. It was only at boarding from NY to Costa Rica I was informed of the problem and by then it was too late. After missing the flight I was told by airport Jet Blue staff, including a supervisor, that it was my problem and they could not assist because i bought "the cheapest fare". i was hung up on twice by JetBlue customer service, including once by a supervisor. I blame Kayak and your awful partner ChatDeal for even allowing me to purchase an international ticket without verifying this - you effectively sold me a ticket i could not use. Shame on you and shame on ChatDeal for doing nothing to help me resolve the situation. What a scam.

Like the variety of entertainment options. One crew member was a little on the rough/rude side. Boarding was a mess, attendants didn't do a great job of helping with the luggage storage and it delayed us a couple of minutes.

Horrible. Flight was cancelled, jet blue app not working to rebook, no phone number available to call Jet Blue, 400 ish people in line for the help desk, stuck in Boston for 2 more days had to book new flight with a different airline and still not sure if I will be able to get any refund.

Jet blue just had great service overall! Only a little turbulence heading out of Austin, otherwise the jet stream helped the speed of the trip!

The pilots were awesome and got us there early. Great landing too. No complaints on the flight. Service - a young cabin crew woman was terrible as she seemed to hate her job and never smiled. Why do they hire people like that? Terrible. The cabin crew lead woman was wonderful - very professional (and more mature go figure)

We were delayed three times ,and that destroyed my plans, and reservations

The reps working at the airport counter were dumber than a second coat of paint.

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

Airline changed the gate from Terminal A to Terminal D which is quite far and only sent a text message few minutes before boarding. Around 50 people missed their flight and as plane didn’t wait for them.

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

Well I mean u get what u pay for so 🤷‍♂️

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

Flight delayed an hour. The turbulence was insane. Packed in like sardines. A coke was $4.95 no snack or a drink crazy
