Flight was cancelled twice. Moved four more times. Probably the least timely and poorly run airline I have ever experienced in my life. I have traveled hundreds of times to dozens of countries and this one takes the cake.

Flight was cancelled twice. Moved four more times. Probably the least timely and poorly run airline I have ever experienced in my life. I have traveled hundreds of times to dozens of countries and this one takes the cake.

Excellent crew, good flight. Flight was delayed about 1 1/2 hours though.

Pros: "The ground crew and flight crew were great."
Cons: "Would have appreciated easier steps (lower risers) for boarding. Arthritic knee makes it hard for me to manage the high risers between steps. Also having armrests would have made the flight more comfortable."
Pros: "I loved the small craft and easy boarding."
Cons: "Flight is a little slower with a smaller plane, but that was expected."
Pros: "So fast and friendly crew. So much easier to fly to Morgantown, instead of driving. Plus the views from above are so great."
Cons: "Flight could not be better for a commuter connection."
Pros: "Awesome crew. Simple check-in and boarding. Beautiful, scenic views. A+!"

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

The pilots were good. Disappointing when planes don't have electrical ports

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

Our flight was delayed in Atlanta. The staff could have gave us an explanation for the delay and how long it would be.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

The experience was good and the flight departed on time and landed early

On 2 different flights the wifi was horrible and there was no drink or snack service.

Inflight entertainment stopped working as we taxi to runway and never worked again until landing and taxi to gate. Grrrr

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

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.

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.

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.

I paid just under 200 for flight and luggage, then paid 200 to change the flight, then paid 100 for a carry on. Then the cancelled the flight. Of the 500 I spent they refunded 250. I bought a delta flight for 270 never flew with spirit, but spirit kept 250, not even refunding the 100 for the carry on though they cancelled the flight (for weather on a day with only a slight rain ).

Flight was canceled. Knew there was weather, and were notified of 20 min delayed, and then suddenly canceled. Next reschedule was for 2 days. No help other than to refund. Thankfully full refund and appreciate that. I appreciate discounted airline but felt they could've done more for customer inconvenience.

Flying on Spirit Airline is a penny-pinching beat down.

Retired military should be able to board with Active duty like Alligint airlines does

Flight was late taking off. I think the crew and pilots did a good job. It definitely worked for me. I would fly spirit again thank you.

Never made it to Atlanta due to the horrible policy of having to be at the gate 1 hour prior to departure. I was at the airport and the plane had not left Baltimore, but was not allowed to board.

Flight left very close to original projected time. Paid for checked bag weight overage (my fault). Plane was literally brand new & this was its 2nd flight. Seats were alittle uncomfortable (I'm 5'11 * 175lbs and was alittle cramped, & brand new seats had little cushion). Food options were good. Main thing was flight took off & landed on time.

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.
