Pros: "The KLM ground staff were extremely helpful and reassuring when there was confusion with my ticket."
Cons: "I booked KLM flights (Cork - Tampa return) but the planes were in fact Aer Lingus and Delta. So I have no idea what KLM is like. When I checked in at Cork the ground staff could only give me a boarding card for the first flight. For the second one she said I would have to go to the Delta counter in Amsterdam. It was difficult to find a counter there or staff as check-in was all by computer. The computer kept saying 'error' when I put in my code. I eventually was directed to a KLM desk (nicely hidden). I was told that my seat no longer existed. At this point the flight was ready to board. Thankfully the KLM ground staff were extremely helpful and reassuring and upgraded my ticket to economy comfort. On the way back, I could only get a boarding card for my first flight. The second two I had to collect at the boarding gate of the second flight."

Pros: "The crew was great"

Pros: "Quick boarding, on time departure and early arrival. No waiting for a gate at LGA upon arrival - excellent."

Pros: "To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal."
Cons: "It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car."

Pros: "A nonstop flight, with a friendly efficient crew, met my expectations. A crew member went above and beyond when I asked for a coffee stirrer with my coke and ice."
Cons: "I've been spoiled by another airline's access to screens on the back of the headrest. I have my own hand held devices to entertain myself instead."

Cons: "Too long of a layover when flying from san diego through phoenix to detroit. Need to look for improvement in scheduling to make this a trip enjoyable."

Cons: "Flight was late, got a message from Kayak that it was delayed 3 hours...thank goodness I happened to check again, because then it was only delayed for 41 mins, then it gave me an update that it was only 21 mins delayed, then went back to 41! Pretty inconvenient, and it would have been nice to get a text, not just some silent pop up"

Cons: "Delayed a total of four hous!"

Cons: "good"

Pros: "On time arrival"
Cons: "Everything else"

Pros: "Snacks and Beverage"
Cons: "Delays"

Pros: "Always on time and always comfortable."

Pros: "Boarding was good, Good flight , good service , plane was small for the distance with limited space for movement ,"

Cons: "Got to charlotte with 80 minutes to connect. Sat on the tarmac for 60 waiting for a gate. Missed connection by <5 minutes. Thanks, AA!"

Pros: "Non stop"
Cons: "Airline"

Cons: "Boarding took forever, the flight was over 2 hours late which caused me to miss my connecting flight and my military orders were not honored - I still had to pay extra to take all my gear back to my duty station. Never had that issue with any other American airline."

Pros: "Good crew."
Cons: "The plane was delayed for two hours!"

Cons: "No food or beverages for me. I slept comfortably on my flight"

Pros: "Clean environment of the terminals and the speed of the shuttle."

Pros: "The movies"
Cons: "No Food"

Cons: "Delayed three separate times, American Airlines employees were rude when asked why the flight kept getting delayed. Arrived 3 hours later than expected."

Cons: "Flight from Ny to Detroit was delayed for 2 hrs. Coming back was worse after multiple delays, they cancelled the flight. they put me on a flight for next day with 2 connections which will reach ny almost 20 hrs later, no aplogises, no hotel room. After more calls put me in another United flight later that night which also finally got cancelled. I had to book a new flight with delta and paid $460 on the spot for that. Still awaiting my refund from American for the return leg which was cancelled and left a lady traveling alone stranded at Detroit airport in the night. Apology or compensation -- forget it, you will never get that! Only now if they can refund my cancelled flight..."

Cons: "Would be nice to know ahead of time if flight is equipped with an in seat television so as to be prepared to bring headphones."

Pros: "We arrived safely"
Cons: "Delay disorganized staff that was not friendly or helpful lost luggage"

Pros: "All great."

Cons: "They charged $3 for water, nothing complementary."

Pros: "Crew was friendly but did not enforce wearing of masks and deplaning was chaotic to say the least with everyone pushing to get off the plane"
Cons: "Enforce the airline’s own policy of wearing masks. About 1/4 of the passengers of the waiting to get on the plane at PIE did not wear a mask in the terminal, even though it is the policy of the airport. Chaotic deplaning in BNA with all passengers rushing to the front of the plane trying to get off. Rock hard very narrow seats."

Cons: "Give complimentary water"

Cons: "Was surprised to see 0 social distancing in the plane. It was packed and not everyone had masks. Should be mandatory."

Pros: "The passengers were spaced out, so we could actually social distance."
Cons: "Not all passengers wore masks. During a contagious pandemic. What the actual hell? Also, the tray tables are too small to use for anything, and we didn’t even get a free drink. Water and soda are so cheap, it’s absurd. I’d never take Allegiant again if they weren’t basically the only airline operating out of my town’s small airport."

Cons: "No help with the Coronavirus bs. Customer service blows"

Pros: "The gate crew was absolutely wonderful. They made the delay bearable. The were very entertaining and friendly."
Cons: "The delay. Couldn’t be helped, but still annoying."

Cons: "A place to out my bottle of water"

Cons: "The padding on these seats."

Cons: "Alligient air is an excellent economy airline that flies non-stop to smaller cities."

Pros: "Cool"
Cons: "Good"

Pros: "On time"
Cons: "Seats could recline"

Pros: "Price of ticket. Crew was efficient."
Cons: "Baggage limitations are not clear: especially when the ticket says no carryon luggage. What they mean is anything that fits under your seat and is under 20 lbs is OK. Seat did not recline. Leg room was poor."

Pros: "Original low price for reservation"
Cons: "Large amount of additional fees making the original 'good' price not so 'good'"

Cons: "Allegiant needs to get stuff together when it comes to boarding."

Cons: "Bad turbulence throughout the entire flight. Hot temperature during majority of flight."

Pros: "Everything was perfect. New plane, super clean!! Even though the seats don't recline, they're still quite comfortable. I love how wide the aisle is...people have plenty of room to move around."

Pros: "Price and timeliness"
Cons: "Airline broke the stroller we had. That could have gone better."

Cons: "Delayed due to weather"

Pros: "Very efficient. Arrived early."
Cons: "Seating very tight."

Pros: "Ticket prices are always the best. Even though The flight was delayed by 30 minutes we were only 15 minutes later into the terminal"
Cons: "The flight was delayed by 30 minutes but we were only 15 minutes later into the terminal"

Pros: "Efficient, direct flight, outstanding price, quick boarding, left late but arrived on time"
Cons: "Nothing. I did not try food or entertainment on this flight."

Pros: "Smooth timely flight without incident."
Cons: "As retired military we were to have assigned seats since we purchased our tickets but somehow our return tickets separated us by 2 rows & opposite sides of plane. We were supposed to be in an isle seat & a window seat in the same side & row. We do appreciate all Allegiant Air does for the military. Wish all airlines did what they do."

Pros: "Timeliness"
Cons: "Hsve to pay for drinks & snacks"

Cons: "I dislike their pricing structure."

Pros: "Our trip to Knoxville was great- no complaints. A/c cool— flight on time."
Cons: "Trip back to FLL air was not working well. Plane dirty as well."

Pros: "It was great"

Cons: "Lousy airline. Left gate late and unfriendly crew. Wanted to charge me for carry on."

Pros: "To be honest nothing"
Cons: "Missed flight any no one was willing to help us pure BS"

Pros: "Quick and easy boarding, on schedule and the cleanliness of the cabin."
Cons: "Extra charge to make use of the overhead bins. This does not include extra work or cost for Allegiant. Lack of legroom; take out two rows of seating and make the current size of travellers comfortable."

Cons: "I am so angry booking with them. I booked the flight and then thought, ok I will add a rental car. It said clearly that the rental Car could be canceled up until 24 hours before the flight. Well, 2 weeks before the flight, my friend said, don’t get a rental car, I will have my car. So I cancelled and only then did I find out that once I booked it through their site I could not get a refund for the car and I could only get a voucher for use on one of their flights! And only after they take out any fees and costs that was accrued! So angry!"

Cons: "Our Kayak reservation did not state that we would be a boarding level that did not allow for a carry-on item. This needs to be more clearly identified."

Pros: "After the delay, we were treated to complimentary soft drinks and snack mix. This was after sitting in the plane for over an hour, though."
Cons: "We spent two hours of the delay in the airport and then eventually boarded. However, another problem with the plane developed and we waited for at least an hour more in the incredibly cramped plane. The seats are bearable for a short flight, but they’re hard to endure with multiple delays. The boarding was also disorganized. There were two announcements: one for people who needed extra time to board and another for the final call. Nothing in between."

Pros: "I chose this flight knowing it was gonna be a little cramped and no snacks. But I loved the price, so I booked it. The unexpected bonus was the crew. They were down to earth and funny."

Pros: "Nonstop on time and as expected"

Pros: "Didn't mind paying for bags, seat, snacks, drinks,.....but a 10hour delay!!!! UNEXCEPTABLE Will NEVER use this airline again!!!"
Cons: "10hour delay!!! No weather problem.."

Pros: "Boarding speed and flight"
Cons: "Uncomfortable seats, does not recline, even water is for sale."

Pros: "Cost of tickets, airport locations-and more convenient travel utilizing smaller airports."
Cons: "Baggage fees are outrageous, no complimentary amenities or refreshments. Flight attendants were rude in asking parties to return to assigned seats, while there were several completely open rows towards the back, (no obvious or explained reason aside from "assigned ticket seats" that they should remain empty. Families or companions could have traveled together- seemed unnecessary to prevent this, only gain noticed was Flight attendants satisfaction at denying seat relocation."

Pros: "The friendly staff made our daughters 21 to Vegas absolutely perfect"

Pros: "The original price points for the direct flights are wonderful. You can actually book the week of a trip and save hundreds because those prices will probably still be the best. That is, until you learn about all of their extra fees."
Cons: "Wow, they sure do add extra fees for everything. Watch out. In the end, I bet it was cheaper to book with a major airline like American. They charge extra for each bag, including your carry- on, when you pick your seat you are charged depending on where it is in the aircraft, if you want a drink or food on the plane you will have to pay, if you do not print your ticket prior to arriving to the aiport they will charge you, etc."

Pros: "friendly staff and clean enviornment. no nonsense flight."
Cons: "nothing to say except that seats could be a little more comfortable."

Pros: "Last week I flew to Florida on this airline. I quickly wrote a stellar review because the flight crew was sincere, nice and kind. Apparently, that is against policy and on this flight there was no hint of that nice attitude. No frills, no courtesy, just transportation."

Cons: "Not to be helped, but was a bit bumpy."

Pros: "The food vouchers for 5 hour wait and water/beverages available. Liked alligent app for boarding pass available without printing."
Cons: "The 5 hour wait while the plane was worked on was unexpected. Not a lot of extra space for a near 6 hour flight. Seats do NOT recline at all. The other plane they boarded us on smelled like dirty shoes or diaper."

Pros: "First time flyer on this airline... I loved that it was a DIRECT flight halfway across the country."
Cons: "Where to start... i guess for starters EVERYTHING is an upcharge. I was suprissed the seatbelts were included! Less legroom than a Cesna 152 and surrounded by 159 of my closest friends. And i mean SURROUNDED. That cabin is SO tight! So tight in fact the seats are a blow mold plastic with roughly 1.5" of foam and fabric. Think go-cart bucket seat with some foam rubber and pleather. Then there's luggage... My carry on bag (that I've used for 15yrs) was too big for the jig at the counter so got to check it for an additional $10 (above the $30 i had to pay to bring it) and they charged me $40 for my original check bag. The hitch is that they only allow 40lbs ($1/lb) for that check bag when the rest of the industry says 50lbs is the norm. Oops, gotta pay for that too! And wait for it... sodas are $2 in flight!"

Pros: "The price"
Cons: "Everything"

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: "Really smooth flight, quick and easy to Las Vegas..."
Cons: "Paying for checked luggage..."

Pros: "The crew was good and had customer service"
Cons: "After an 36 hour delay and only $8 meal voucher in Las Vegas, highly disappointed!!! The next flight was late arrival and Late boarding. everything to include water and sodas are extra fees. not impressed and will never fly Allegiant again"

Pros: "Didn't have any problems. Flight was on time departing and returning and non-stop."

Pros: "Worst flying experience ever"

Cons: "I was informed today that one of my checked bags was picked up by another customer who eventually realized it was not her bag. She brought it back to the airport and refused to turn over the bag until the airport compensated her. (How this happened I have no idea because I stood right by the entrance of the baggage claim and never saw the bag come out). The customer refused to return the bag until the police became involved at which point she agreed to write a note confirmed she did not steal anything. The bag then needs to be sent to me in 2 days and I'll have to verify myself that indeed nothing was taken from the bag. I'm very concerned how this individual came to be in possession of my bag considering, again, I stood right at the entrance of the baggage claim conveyor belt from the time it started to when it ended. As a result, this experience really made me feel frustrated and violated."

Pros: ":("

Cons: "Never made it because of stupid United"

Pros: "The pilot got us there safely. Good deal of turbulence."
