Pros: "Our plane was struck by lightning and therefore not able to fly, so we were deboarded and left to wait until a rescue flight could come in from Boston. Over the course of 4 hours, the crew kept us updated with every little change and were all very helpful! Once we were able to board the rescue plane, the crew handed out complimentary candy and drinks to help ease the wait times. Highly recommended!"

Pros: "Non-stop flight at a reasonable price"
Cons: "Food choices are very limited"

Pros: "I have never experienced this before. You stand in line to get a tag for your bag. Then you stand in line to check your bag. Then you stand in a Disney style HUGE line just to get to the escalator to take you to the second floor so you can go through security. Thank goodness for TSA precheck! That line was long but not very long like the other line."

Cons: "The beer"

Pros: "Would highly recommend the connection and the Allegiant jet was a fairly new Airbus, very comfortable."

Cons: "Plan to curtail service at AVP! Planes are always full!!"

Pros: "on time, hepful personnel"
Cons: "my gate checked luggage was lost"

Cons: "It was raining when we landed and we were told the guy didn't want to come out in the rain to open the door so we were stuck on the plane for a while. Being Florida, it rains. If it's your job to pen a plane door, I would think it's reasonable you do it in the rain sometimes. Then up to the passengers on board whether or not they want to get out of the plane when it's raining."

Pros: "New plane!"
Cons: "Boarded too early!"

Cons: "Our flight was delayed 4-5 times before it was cancelled all together and rescheduled for the following day. I lost over $200 in hotel charges and valuable time with family. A 3 day trip was decreased to a 2 day trip. Extremely disappointed. After sharing our experience with others we heard the same thing happened them."

Pros: "Nonstop on time and as expected"

Pros: "On the way there and back the staff was friendly, the flight was smooth and and overall everything was just great. This was my first time flying with Allegiant and I will definitely do it again."

Cons: "After the horrendous delays getting to my destination I just bit the bullet and bought new tickets (duplicates) on a different airline to get back home-- rather than risk a repeat experience. Ended up costing an extra $300 but at least I didn't have to spend an entire day in an airport trying to keep my 7 year old from losing his mind."

Pros: "They offered a direct flight from Cincinnati to Austin. The price was good, even though they charge for carry on."
Cons: "They land at the Austin airport, kind of. Once we landed they took us to a Remote terminal which required waiting for a bus to fill up and then take you back to the actual airport. There was no quick way for the bus to return and it has to drive for 15 to 20 minutes to get to the main airport. I took 1 complete hour from when I landed to when I got in my car in lot D."

Pros: "Comfort and speed of the flight. Attentive staff!"
Cons: "Need one craft beer"

Pros: "While I enjoy the fact that Allegiant offers direct flights to Laredo at an affordable price, the planes really need to be updated."
Cons: "We really disliked that we boarded the plane and just before taking off they made us get off again and never did confirm the real reason. The planes really need better maintenance since this is the second time in two weeks we have to change planes due to problems."

Cons: "Delayed 5 hours!"

Cons: "Even snacks and water are only available for a fee. Seats do not have much padding and are not comfortable."

Cons: "No complaints."

Pros: "Everything was super easy with Allegiant. This was our second time flying with this airline, and even though you feel like you get nickeled and dimed to death, the overall price is still much lower than any other airline. The plane was clean and the crew, both ways were awesome and in-tune with their passengers. Don't be fooled by the pricing, this is really an outstanding airline, we will fly again with Allegiant!"

Pros: "It's like taking the public bus during rush hour. Organized chaos. But I guess you literally get what you pay for so, yeah. The crew was awesome though. No qualms there."
Cons: "Disorganized boarding. Even the extra room seats are cramped. Bathrooms are a step up from a porta potty. DO NOT SIT NEAR THEM unless you plan on holding your breath the while flight."

Cons: "everything was poor"

Pros: "The Bacardi"
Cons: "How small the bottles are."

Pros: "The price and the fact that our flight left late but still arrived almost on time."
Cons: "The gate agent wouldn't switch our seats so we could sit beside each other. We've done this multiple times if we find ourselves not out beside each other and it's never been a problem before. He claimed he had to charge us to do this. We have never been charged before. We fly Allegiant often. The on-board flight crew were so not friendly at all. Typically Allegiant flight attendants aren't as happy as Southwest but they're at least cordial. This crew we're just unhappy, snippy, a little unprofessional (saying huh or what instead of excuse me. Pointing people to things instead of getting it for them or walking them to it) and at one point one stewardess was just rude to a passenger."

Pros: "friendly staff, good take-off - landing, all that jazz"
Cons: "Not knowing it would be a late take off. Other than that, very good."

Pros: "Didn't have any problems. Flight was on time departing and returning and non-stop."
Cons: "When I booked my flight, the website didn't give me an option of whether I had a carry-on or checked bag."

Pros: "EXECELLENT BOOKING & FLIGHT, WILL CONTINUE USING YOUR SERVIES. JOHN"

Pros: "It is a low cost carrier. You get what you pay for"

Pros: "No issues. Responsive flight attendants, on time"
Cons: "$5 to print my boarding pass at airport. and using online tools to print was not intuitive Seats that don't recline."

Cons: "When we booked our flight you seperated us on the plane seating Why? That really sucked. We then found out you charge extra to sit together for each of us. We would not recommend first time travelers to your airline for that reason"

Pros: "NOTHING"
Cons: "First time flying Allegiant: Head's up! They charge you for EVERYTHING and I mean EVERYTHING and the overall experience is awful. Would you like to know what it's like to fly on a plane bound for extradition to a foreign prison...fly Allegiant Airlines. Would you like to experience the unexpected thrills of being nickeled and dimed at every turn....fly Allegiant Airlines. Would you like the answer to the question posed after paying $100 for two carry-on's: 'could this get any worse?' Answer: It does!...fly Allegiant Airlines. Here's how it all starts out they welcome you to the terminal with a wonderful opportunity to pay $5 for printing your boarding passes (unless you download their app). How could a piece of paper that small that no other airline charges you to print cost $5 you ask? Well that is the magic of Allegiant Airlines at work, if they can't make something simple; both costly and annoying then you aren't flying Allegiant Airlines. You then inquire at the check-in desk can my loved one and I sit together, and they say sure but you will have to do that at the gate. Ok some positive news here...but then it sinks in.. wait a minute what Airline are we flying again? ...Allegiant Airlines, and what is their motto?? If it is simple and easy it shall become both costly and wildly inefficient. You arrive at the gate with hope in your heart and they then tell you, umm no. Who ever told you that is a fool! You can make no changes to your seating this is a 40,000lb aircraft with a 300,000lb lift capacity and it can't handle you sitting next to your girlfriend it would compromise the avionics and we would all surely die. Then why on the app did it show open seats? Seats of course for a price! Not by section like a normal airline ohhh noo a price that was completely different for every single seat as if the seats were in competition with each other in some high altitude economy that makes far less sense at sea level.The helpful response to this inquiry was 'oh well that was then' I am looking at it right now. I don't know what to tell you.. What's next?! A surprise $50 charge per carry-on! Unless you read the small print on one of their emails that is filled with advertisements they make it look like another advertisement, I'm going to go out on a limb and say INTENTIONALLY as it is never mentioned on: (The check-in email, the purchase confirmation email, not mentioned by the ticket counter, not anywhere on the app, not written anywhere on the electronic ticket despite them announcing otherwise) They instead tell you right as you are boarding the plane and have absolutely no choice in the matter and have done this innumerable amount of times as the flight attendant was well versed in de-escalation protocol and a security guard was positioned an arms length away as she deftly charges your card on file... I have run out of characters for this post I can only assume this comment section is run by Allegiant Airlines.."

Cons: "Late."

Pros: "Online movies and TV"

Pros: "Easy to board friendly"
Cons: "The snack food selection, price on wifi"

Cons: "We were told there wasn't anymore space for carry ons so I had to check my bag. I got on the plane and there was plenty of space for bags. There needs to be better more efficient communication about baggage space."

Pros: "Departed on time, arrived 1/2 an hour earlier than anticipated."

Pros: "Well organized"
Cons: "No free wifi :("

Cons: "My suitcase was ruined in transit to Kansas City. The help desk basically asked me to leave my bag behind for three weeks to see if they can fix it. They had no means of looking after the contents. Was I suppose to carry my content???This was ever so frustrating since the suitcase was brand new. Then the lady told me that my warranty on the bag will cover the damage. It was obvious she was not willing to help and did not have a clue what she was doing thus I just logged the complaint and had by suitcase sorted out the San Francisco Airport. They were very helpful."

Pros: "Roomier comfortable seating."
Cons: "Paying for luggage and food"

Pros: "At least there was room to sprawl out and rest."
Cons: "We boarded our plane and during preflight check on the runway the captain learned there was mechanical error (in the right engine fuel something). The issue could not be solved and we had to change planes. On the second plane, the captain shared with travelers that "and two loose wires were found, so it's good we caught that and changed planes". What the heck? Shouldn't basic functions be checked before a plane is boarded? What was supposed to be a 1030 red eye, turned out to be a 1 AM bloodshot eye."

Cons: "A little tight"

Pros: "Direct tv"
Cons: "None"

Pros: "On time"
Cons: "Food quality"

Cons: "Very rough landing ."

Pros: "Hair plane was very clean"

Pros: "Safety."
Cons: "More options for Food (snaks and drinks)"

Cons: "All went well, I think thAt on flight 3 hours or more beverages and a snack should be free."

Cons: "Not 2 hour delay leaving."

Pros: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge."
Cons: "I did not like anything about this trip. The check in process was a pain. The boarding was chaos... (Of course, same 2 careless ladies were in charge)."

Pros: "Staff was great. Baggage and service was handled well."

Cons: "3hrs late"

Cons: "Bags were lost by multiple passengers."

Pros: "Nothing."
Cons: "I was unable to board my flight because the individual attending the desk for check-in left more than 45 minutes before the flight. I was unable to get my boarding pass and in addition, could not check in my bag as I paid for it. I was forced to purchase a flight double the price on a different airline in order to make it back to NYC in time for my interview the next morning. I am absolutely horrified at my experience -- I am a recent graduate in the process of looking for a job and should not have had such a horrible flying experience. I would like a refund."

Cons: "The check-in process didn't work and was confusing. Every time I tried to check a bag and pay the reduced fee, the website returned me to the window asking for username and password again. I could not check-in on line and had to pay full fee for checking my bag. I was frustrated and at the airport there was no consideration for giving me the reduced fee in light of the website malfunctions by the agent checking me in. Also, the steps during the check-in was confusing - trying to sell upgrades etc, instead of just taking you thru the check-in steps."

Pros: "The pilot got me safely to Atlanta"
Cons: "The airplane was very filthy The seat in front of me was very dirty I asked the pilot for a sanitizer napkin he said that they didnt have anything. I asked for a paper towel so I could clean the seat and it took him 25 minutes to bring it. It just seem like the plane was really nasty Th 2 guys in my row saw the same thing"

Pros: "Nothing"
Cons: "Everything"

Cons: "That you have to pay for a carry on, and when I tried to go on line to pay for a carry on I couldn't find where to pay for it so I had to call frontier to pay over the phone"

Pros: "Nothing"
Cons: "The attendees left the counter early and I was not allowed to board."

Pros: "Nothing"
Cons: "Charging for baggage and not making it clear before buying tickets. Having to wait for baggage."

Cons: "Too much nickle and diming. Website confusing"

Pros: "The crew was exceptional!! It was like booking a comedy club act in addition to the plane ticket. Made the run super enjoyable. Frontier fares would be worth the savings for me if available connections to the cities I need to visit were better & if I could check a bag at a reasonable cost. See my objections in other box."
Cons: "I still cannot get used to the lack of complimentary beverage during the flight - nor the fact that Frontier charges for carry-ons & tries to get me to "buy" a seat assignment when checking in on-line. Very deceptive web site. My principle dissatisfaction with airlines these days is being charged for every item they can possibly scrape an extra penny of profit from. Most people cannot manage a trip without some type of bag. If air fares reflected the savings, then the offset would be worth it - but most often that is not the case."

Pros: "Outstanding flight experience. Haven't flown Frontier for decades but definitely plan to do so in the future."

Pros: "It was quick"
Cons: "The charge for carry on"

Pros: "A bargainprice can be had if you have no luggage. Be prepared to sit up straight on fairly hard seats that don't recline. I cannot complain about spending a week at my daughters, where I already have clothes, for $91."
Cons: "I cannot complain about spending a week at my daughters, where I already have clothes, for $91."

Pros: "MCI departure efficient"
Cons: "DIA tarmac delay, unable to get to gate"

Cons: "It was late by 6hrs and no other alternatives"

Cons: "Couldn't move the seat back at all. Couldn't sleep."

Cons: "Plane was an hour late. Then we waited an hour on the runway after we landed."

Pros: "Friendly flight attendants, quick boarding."
Cons: "Waiting game for a gate to open up."

Pros: "wheelchair attendants were courteous"

Pros: "The chairs in the plane"
Cons: "The fact that they rescheduled a flight but then weren't ready when they said, I understand delays but professionalism is key when not communicating to clients. The fact that they said they'd give a voucher for next flight, yet I'm still waiting on it to get emailed to me, it's been past 48 hours"

Pros: "Friendly and couteous"
Cons: "How the seat selection goes, having to pay more to have a different selection"

Pros: "Great. ..."

Pros: "I like the low fare and the non-stop flight. The low fares made it possible for me to fly to Atlanta, GA, for an emergency, and money wasn't an issue!"

Pros: "I liked the price that I paid for the ticket!"
Cons: "I didn't like having to pay for the bags checked or carry on, or the seat, soda, snacks, and anything else you might want."

Pros: "Nothing"
Cons: "Everything"

Pros: "Cheap non stop and we arrived 10 minutes early"

Pros: "Its a quick flight"
Cons: "Boarding took longer than norm departing and arrival. They took away reclining seats and any type of entertainment. Not really like it used to be."

Pros: "Flight was on time, actually landed ahead of schedule."
Cons: "Had to wait on tarmac because gate was not ready. Did not know about high bag fees and fees on everything else. Had to wait for an hour after pulling into gate for luggage to get in. Seating very uncomfortable and could not adjust the backs. This was my first time on Frontier, will pay extra to not fly frontier again"

Pros: "Nothing"
Cons: "Frontier airlines has left an unforgettable experience to cherish in the years to come. I can say it was undoubtedly one of the impeccably worst airlines to travel ever. My flight was scheduled to travel from Kansas City to Chicago at 7:23 pm on Thursday. Initially I got an email from them saying the flight has been delayed and the new departure time is 9:45 PM. When I searched about it in GOOGLE it showed me that the flight has been cancelled, Furiously I called the customer service and they weren't even having an idea about the flight getting delayed in the first place. I had to travel to airport which is 50 miles from my place just to know that the flight got cancelled and the next flight is on Sunday. Due to their technical failure, I had to wait till Sunday to board a flight to Chicago(They gotta be kidding, wait 3 days to board next flight). I had to cancel few other flights, meetings and hotels as I am not able to board this obnoxious flight. Overall, The customer service is lackluster . Their website is very slow and has false information. The refund process is bad. They dont even intimate you through email if the flight is cancelled I am referring this airline to all my colleagues and friends. If you have a lot of money for procrastination, you are welcome to travel with this airline."

Pros: "Cheap flight"
Cons: "Extra charges for baggage"

Cons: "The plate was late with no reason given."

Cons: "Seats. Fees associate with bags. Customer service"

Pros: "We landed safely."
Cons: "3 hours late. Not their fault but not mine either. Then they have the nerve to ask me to BUY a soda on the plane for like $3. They should have comped everyone a beverage for the long wait. Told us the wrong bag claim area. No smiles from the crew."

Cons: "They charged be $45 for a small carry on bag each way. So my $168 ticket turned into $258. I will check with other airlines that shoot straight with their ticket prices."

Pros: "I didn't receive a smile or even an acknowledgement from flight attendents. Couldn't hear the safety speech at all. Annunciate and speak clearly would be my suggestion. This person sounded like they had a mouth full of mashed potatoes. I won't fly frontier again even though it used to be my preference. The baggage fee, not even a complimentary drink?? Uninterested staff. Very poor customer service. However, the pilot got us to destination on time and w/out mishap, hence my OK rating. Otherwise super disappointed in crew and staff."

Cons: "Arrived half an hour early but my seat was already sold. Wasn't offered to be put on a different airline and didn't feel like I was cared for as a customer."

Pros: "The low price of the fare"
Cons: "1. All the added charges even for a refreshment 2. The obnoxiously loud noises coming from the plane mechanics 3. A group of 5 that were drunk, belligerent, loud, and inappropriate 4. Lack of cleanliness (old tissues & trash stuffed in the seat pocket, trash on the floor, looked like throw up in our aisle-our entire aisle asked to move seats) 5. Stewardess speakerphone so loud It was painful"

Cons: "Arrived at my destination and items were missing from my bag."

Pros: "The flight was uncomfortable, chairs don't recline, even the 3 ounces of apple juice wasn;t free although the dude did give me some water so that was nice.They charge you for every little thing based on a business model I like to call Pettiness. The one thing they didn't charge the lady in the next seat for was her 50 pound kid who rode on her lap. And the website for checkin and buying baggage was glitchy and difficult to navigate."

Pros: "Flight crew was good once we were able to board."
Cons: "3 hour delay in getting to destination"

Pros: "Flight staff was nice."
Cons: "Seats were awful as was the mini tray tables"

Pros: "Nothing"
Cons: "Customer service was rude. Seats were ironing boards with pleather covers, we were all especially jammed in. Airline crew was not pleasant. The best thing was when it was over."
