Delayed departure. Delayed after landing pulling into gate. Delay due to sky bridge malfunction

Great. Loved that there was WiFi on flight to keep in touch and excellent service of beverages and snacks.

Flew business class. Everything was excellent. No issues at all. Not very many “good” movies to choose from. But lots of mediocre ones

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

great flight. Pilot was communicative, flight attendants were excellent. Really nice experience except my tv didn’t work.

The best experience that I have had traveling with JetBlue!

Overall, the flight was better than the flight I took to go to Florida, which had a bunch of problems. The crew is really nice and the plane was new so it had a small problem when we were on the runway, but the flight itself was great. They even made some time back up, which is always a good thing.

Crew was just ok. Flight was packed. On a 3/4 hour flight I would hope they would come around more than once to see if you needed anything further. Not very attentive.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

It was okay, no wifi or entertainment real disappointment. Staff onboard not very friendly.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

It started with multiple delays, cancellations, re booking, 5 hour lay over and finally on a plane from Chicago to Pittsburgh. Gates, times, etc were changed multiply times. Once on the plane, staff was fine, but built in tv did not work and could not even turn it off. Light at eye level the entire trip, so sleeping was near impossible. No snacks or drinks given.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

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

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Left on time. Arrived early. Turbulence coming in and gate not open due to early arrival but expected.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

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

Poor communication from flight crew. Passengers were left on plan for over 4.5 hours, no food or drinks were offered. Flight was eventually cancelled because flight crew/flight attendants went over there work hours. No accommodation were provided. .

The flight was fine. The itinerary change from original booking was not good. We were originally leaving at 12:50 pm. The change to 8:29pm put us getting home in the early morning hours the next day. Then having to wait over an hour on the ground for a parking place to get off the plane was exhausting.

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.

Over an hour delay in departure but I was notified beforehand. Another delay on tarmac upon arrival at LGA. We ended up departing the plane almost 2 hours later than expected

I fly Frontier because it’s affordable. I understand that the seats are tight and not the most comfortable…but that’s part of it. The problem with this flight was that there was a group of travelers directly behind me at the back of the plane who were ridiculously loud and obnoxious the entire flight. I’m pretty sure they were drunk and I could periodically smell an odd odor that I believe was one of them using a smokeless vape pen. The stewards had to remind them to keep quiet during the pre-flight instruction, but that was it. They never said another thing to them for the rest of the flight. It was a miserable.

I checked a bag because it was $5 less than carry on. They managed to lose my bag on a 2.5 hr direct flight! Frontier has no airport staff at baggage claim to help. As soon as I got home around 11 pm I tried to use their online system to file the claim for lost bag - system wouldn't take the # on my baggage claim ticket - said it was not the correct number. Also said that I had not checked a bag, which wasn't true - even my online boarding pass showed that I had checked a bag. Wasted about an hour on that process with no luck. Tried again in the morning - same thing. So tried online chat with Frontier bot - waited 35-40" twice to be connected to a baggage agent and it never happened. Eventually drove to PDX after work and waited 2 hrs for the Frontier ticket agents to arrive prior to the next Frontier flight out of PDX and FINALLY got some help from one of them, to take me to lost luggage area where I was able to retrive my bag. Probably took 4-5 hrs. of my time and endless frustration to get my bag. This was my first -- and LAST -- experience flying Frontier Airlines. Check-in was also extremely difficult and time consuming. The flight itself (and staff) were fine but everything else about the experience was a total disaster! The fact that Frontier literally has NO WAY to connect to a human voice for customer service (in this case for lost luggage) is the WORST!!!!!

Frontier is a crappy airline nothing about it is honest

I didn't get to do this flight l, hard to review

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Didn't like anything!! Horrible flight. Small seating area and hard seats. Butt was sore after 2 hour flight to Seattle No entertainment or free refreshments No wifi or USB charging receptacles to charge phone entoute like other airliners Luggage rates were 3 times as much as competitors. Difficult to navigate online luggue process to pre pay before flight Overall bad experience WILL NEVER RIDE OR RECOMMEND FRONTIER TO FRIENDS OR FAMILY MEMBERS!!! THIS IS A SHAME!! MOST MESERIBLE FLIGHT OF MY LIFE!! AND I THOUGHT SPIRIT WAS 👎 YOU GOT THEM BEAD HANDS DOWN!!

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

Our flight was delayed an hour, then when we got to board our flight finally, we were waiting in our seats for take off for 45 minutes before it was communicated that there was a maintenance issue therefore we waited on the plane for over an hour while that was resolved. We did not get to Phoenix until almost 3 hours after we were originally supposed to. This was the first and last time I will be flying Frontier.
