Cons: "B.S. all the Delta Boarding groups. Geez, have you lost all common sense! C'mon... I understand the ill/med conditions passengers. How about 1 kid, then 2 kids then 3 kids, w/ cataracts, bladder probelems, Platinum, Gold, Silver, Paper, Plus 1, Plus 2, Main Cabin 1, 2 and 3."

Pros: "Crew and entertainment options were great."
Cons: "Cabin was very loud, with jet engine noise. Could not block it out. Seats were not comfortable."

Pros: "Standard Air France flight. My wife and I like the Airbus 380."
Cons: "The flight left two hours late. Apparently this happens a lot with this flight these days because it's an Airbus 380 coming from Paris to Dulles and turning around. The incoming flight was two hours late, so the departure was late. Our arrival in Paris was late. We made the flight, but our luggage didn't. Our return flight from Paris to Dulles was half an hour late because of people from connecting flights. We arrived about 30 minutes late, but no big deal (unless you had a connection)"

Pros: "Fly attenden alwas with a beautiful smile"

Pros: "Nothing particularly stands out. I did arrive safely."
Cons: "First class did not come with lounge access? Drinks were not cold. Bathrooms were falling apart and came with a disgusting odor. Time to retire these aircrafts."

Pros: "Flight attendants were nice based on the situations beyond their control."
Cons: "Flight was delayed for about three hours, due to mechanical issues with the second engine not starting. We sat on the the plane for over an hour and half. Some people that missed their connection flights were offered hotel stay. Others that had no connection flight was not offered anything for the several hours of delay that occurred."

Pros: "Never got ticket or email or booking number. Called my bank they said charge still pending. I asked if they could cancel. Bank said yes. Told them to cancel and rebooked throught Delta website. Got eticet. But charge was not cancelled. At airport I had 2 tickets. Working with bank. Today gate agent gave me 1st ticket number. Used Kayak and delt never had this issue. Email not changed or misspelled."
Cons: "No eticket or booking number recieved."

Pros: "That I landed safely"
Cons: "1st class was horrible."

Cons: "I have traveled with my luggage plenty of times through airports and the flight from washington to jacksonville, my luggage came back to me cracked and broken. I was surprised that Delta handling was worse than any of the cheaper flights I normally take and will not be checking any baggage with Delta again."

Pros: "Great and friendly crew"
Cons: "baggage rules, check in with baggage, change fee for flight when it was not customers issue that caused the 5 min delay! Unable to reach reservation desk on line or via phone (neither was the gate agent)"

Cons: "Seeing as I’m still waiting for my flight, more than five hours later I am not inclined to rank it highly. This airport is an embarrassment and I will try my best to never fly Delta again. Weather is no excuse for this."

Pros: "My flight was canceled but Delta rebooked me on a flight leaving at about the same time as my original flight, which arrived just a little later than originally anticipated"
Cons: "My original flight was canceled"

Pros: "Friendly, helpful, kind, confident and easy going flight attendants really made this flight stand out. The seats in economy were comfy and new; the touch screen Tvs were updated and functioned properly. The snacks were healthier. Way to go, Delta! Keep it up!"

Pros: "The fact that there were no snakes on this plane :-)"
Cons: "Same issue... there were no snakes on the plane :-/"

Pros: "The boarding process was smooth, friendly staff."

Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."

Cons: "There delay"

Pros: "Professionalism"

Pros: "Crew"
Cons: "Having delayed flights"

Pros: "The crews were very friendly and everything went as planned. It was a nice flight."

Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."

Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."

Pros: "Everything was great"
Cons: "Nothing everything was fine"

Cons: "paying extra for leg room and checked bags"

Pros: "Everything"

Pros: "Seats were reasonably comfortable."
Cons: "Boarding process was ok (they bused us over to the plane and then had us walking out halfway to the plane's stairs before frantically sending us back on the bus because the plane wasn't cleaned yet). Not a big deal but we were traveling with a 10 month old so miscommunications like that cause a larger inconvenience than usual. The real downer on the flight was when we needed hot water quickly to warm our infant's bottle. The stewardess had begun beverage service and was about 8 rows away from us. My wife hit the call button, expecting the stewardness to come over somewhat quickly. Instead, she just continued beverage service and got to us about 15 mins later. By that point it was too late and the baby was wailing from hunger. When we asked why, knowing that we had a small child, the stewardness didn't just push the cart forward and attend to us more quickly, she said she didn't want to do that. No apology, not even a sense of remorse. At the end of the day, a customer's experience will always be tainted by poor service and that is what we received on our flight."

Pros: "GRU to ATL to LEX - all was fine. The plane from GRU to ATL was one of the nicer jets I have ridden in. The ratings above reflect my overall trip of going to Sao Paulo and returning to Lexington, even though the first part had to be re-booked on United."
Cons: "LEX to ATL to GRU did NOT happen because the LEX flights were delayed to the point of missing the ATL connection. While Delta re-booked me on United, my flight arrived 3 hours later than scheduled (so transportation plans had to change), my bag did not successfully move from the Delta flight to the United flight (and was thus delayed in getting to GRU) AND once the bag was received, 4 shirts had been stolen. While a delay/theft claim has been filed with United, this could all have been avoided if the Delta flights had been on time."

Pros: "The movies"
Cons: "Everything else"

Pros: "That I got a soda"
Cons: "Delayed at Ohare by an hour. Sitting on the Tarmac for a half hour in Reagan, waiting for a gate. This was our leg back to DC, after our leg to Chicago four days previously. On that trip I did a review and gave the whole trip a 1 out of 5 stars. That trip was the trip from hell, with delays, waiting on the Tarmac, deplaning, almost cancelled, more waiting on the Tarmac, wheels up in Reagan, wheels down in ORD, and then more Tarmac waiting for a gate. So I was already more than perturbed when this trip had similar outcomes."

Pros: "Everything"
Cons: "Nothing"

Pros: "We had a small technical glitch and the pilot kept us updated. Nothing is more difficult than not knowing what is going on."

Cons: "Horrible delays and many gate changes"

Cons: "There's no room for non skinny people. It was awful"

Pros: "Crew was very nice and very competent."
Cons: "I'm trying to wrap my head around the # of flights that are delayed or cancelled, when I fly on Allegiant. Perhaps, I have just had bad luck. The flight was delayed a total of 5 times for a total delay of about 4 hours. The original scheduled flight was for 6:35 pm and we didn't actually leave the ground until almost 10:30. We kept getting pushed back. I am not certain if it was due to weather (in another area) or required flight crew rest, both of which I would understand. There was no reason posted that I saw. I have a 10 yo son who has Autism and should be in bed no later than 10 pm, preferably 9 pm. I appreciate all that Allegiant does for the military, and therefore, will continue to fly on your airline. I will NOT, however, take any more evening flights as most of the ones I've flown on have either been delayed or altogether cancelled. Again, I truly appreciate your recognition of retired and active duty military. 8/10 is a B and can be improved upon with more clarevoyance and keeping on-time flights."

Cons: "Great crew and smooth ride"

Pros: "Great crew. Everything was on time. Loved it"

Pros: "Price"
Cons: "Communication is always my #1 complaint with Allegiant. They delay flights regularly but there’s never any additional information...they just send you a text or email saying your flight is delayed, never tell you why, but they want you at the gate at the regular time...so you sit there for hours with No further communication and the gate agents never come to the gate to let you know what’s going on or what to expect because corporate has gotten stingy with regard to compensating folks even when THEY are to blame for the delay. Two trips in a row, two weeks apart, they’ve done the same thing to us. I appreciate the low fares, but I’ve just about decided I’d rather pay more for good customer service because theirs just sucks."

Cons: "Major delays, no communication from airline"

Cons: "I love the changes that have taken place. I last flew with them 5 years ago and vowed too never fly with them again. Times have changed and they are a great Airline!!!"

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

Pros: "We had a really nice crew."

Cons: "It is Allegiant Air. Not much more needs to be said."

Pros: "The crew was very nice,,"
Cons: "Im not sure, everything was just so nice,, more chatting mabye talkin more,,"

Pros: "Arrived safely"
Cons: "Almost two hours late."

Pros: "Late"
Cons: "Be on time"

Pros: "No leg room & very misbehaved children sitting behind me. The children screamed the whole time, kicked our seats, and the mother had no control. If you are any taller than 5’9”, you may want to consider an exit row seat to have room for your legs. My knees were jammed in to the seat in front of me."

Cons: "No hot coffee on 7:40am flight. Not right."

Cons: "Seats were not comfortable"

Pros: "When you land at Concord you are right near the parking lot!!!"

Pros: "Crew was very pleasant and professional"

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: "Crew was really nice! Flight was quick and easy"

Pros: "The captain was very good, and we arrived early to our destination. We had to hold back before landing, due to smaller planes landing, so the captain pointed out some areas along our path! Loved it! The flight was smooth."
Cons: "We had to be in the boarding area an hour before the flight was scheduled to leave. However, because of the way that the flights are scheduled, people were still deplaning from the previous flight for 25 minutes after our gate arrival time."

Pros: "Timing and ease of travel"
Cons: "Nothing"

Cons: "It was to uncomfortable to sit there in the plane for so long. I also noticed one of the flight attendants with the long brunette hair kept over looking me but would be in all the guys faces instead. Pretty sure it was a jelouse thing. The shorter brunette girl was really pleasant"

Pros: "The price!"
Cons: "Flights in both directions were late."

Pros: "Check in was fine Wait was short Crew was great!"
Cons: "Seats REALLY UNCOMFORTABLE SAD Could not have updated the seats on newer Jets."

Pros: "Made it home safely."
Cons: "Waited on tarmac 2.5 hrs. Then plane delayed 10 hours. Then waited on tarmac 2 more hours. Horrible first experience flying with Allegiant."

Cons: "Flight was delayed 6 hours."

Pros: "That we made it once we were in the air"
Cons: "The 3 hour delay that should have been announced but we had to get alerts on line not from the airline but Kayak"

Cons: "4 hours late. No explanation. I have flown Allegiant 3 times. Late twice."

Pros: "It was exceervice"

Pros: "Everyone from desk to gate to crew were very friendly. I like alla carte airlines for thier value. I dont need a free soda for and extra $100 ticket price."
Cons: "Needs better organization during boarding. Everyone piles up near the gate. Thry can copy Southwest and make the process smoother."

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: "My kids and I had great experiences with Allegiant Air, thanks in large part to some excellent flight attendants. This was the first flight for both of my children (5, 7) and they had a blast. On our initial flight from Indianapolis to Ft. Lauderdale the attendants even gave each of them their own set of pin-on wings since it was their first time. The kids loved this!"

Pros: "Great price on airfare"
Cons: "Long line for baggage check in"

Cons: "Ground crew at ticket very slow and inefficient. Two groups missed their flight because of it."

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: "It got us there and back for a descent price. The flight was fine but the seats are not comfortable and do not recline. I wouldn't suggest Allegiant for anything more than 2 hours and that was even pushing it."
Cons: "We arrived 3.5 hours early and the line was very long. They must have had a system glitch but didn't communicate to anyone in the line as to what was going on. When it did come time to board, they told everyone in the line that was going to Cincinnati that we couldn't check in until 2 hours before the departure time. Apparently there were some other flights that left before us. If they had told us to keep our place in line and to let other people through, that wouldn't have been a problem. But, they didn't. Their own website says you should check baggage at least 2 hours before your flight and no more than 4 hours before. They took it upon themselves to change the rules on people who arrive early. Then, once they no longer had anyone else to check in, they changed their rules again and start checking in people for Cincinnati about 2.5 hours ahead of time. A little communication and brain power from the staff would have gone a long way. After all that mess, the flight was delayed leaving about 15 minutes without any updates from Allegiant either."

Pros: "I fly this airline airline quite a bit because I have family in the mountains of North Carolina. I have never had a problem with them, I fly out of Fort Lauderdale to Asheville, it's a quick one and a half hour flight. The flight crew is always professional and courteous."

Cons: "No wifi"

Pros: "No much"
Cons: "The flight was over 5 hours late. We were supposed to leave at 6:06 PM and didn't leave until about 11:10 PM. We were supposed to get into Asheville at about 8:00 PM, but finally arrived about 1:00 AM. I fly this route frequently and Allegiant has a terrible problem with on-time flights and communications with passengers waiting for their flights. I am not certain what the problem is, but it is a significant issue with them. Captain was "bubbly" and upbeat without properly managing the passengers' expectations. Bad public relations."

Pros: "On time"
Cons: "Boarding outside in the pouring rain!!!"

Pros: "Flight attendant Lisa was great."

Pros: "The stewardess remembered us from the previous flight and was awesome to my son!"
Cons: "Kind of bumpy and a little late."

Pros: "Clean plane and nice crew."
Cons: "We waited for over 2 hours for takeoff after we had boarded."

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."

Pros: "Airline was great. Told us right away they were only going to do one drink service so we could order two. Left on time and had no issues. Would definitely fly with them again. Even though you have to pay to check a bag, it's still a better deal than any other airline out there. People need to stop complaining about the extra fees, do you want cheap or not."
Cons: "Nothing. Was exactly what I expected for a $35.00 flight."

Pros: "Easy boarding"
Cons: "Slow to get luggage. Seats not comfortable"

Pros: "The flight crew was nice."
Cons: "The staff at Ft Lauderdale airport was not customer focused. They were disorganized and rude. My friend paid $5 for his ticket to be printed and, at the very least, they should refund that. I'll never fly Allegiant again."

Pros: "Everything"
Cons: "Paying for my carry on bag."

Pros: "Highly recommend"

Cons: "Not clean"

Cons: "Not sitting for an hour on the runway with no A/C."

Cons: "Everything. Rude crew. Not allowed to use restroom."

Pros: "Great flight!!!"

Cons: "Why does the airport have so many flights coming in at the same time that you can't deplane as soon as you touch the ground? Feels like someone doesn't know what they are doing! Very frustrating! I was late to my event due to this!"

Cons: "Broken luggage"

Cons: "Eveything"

Pros: "The flight was rerouted due to the blizzard, but the staff made it very pleasant and easy to make it to my destination on time."

Pros: "Great pilot. Smoothest landing ever"
Cons: "No snacks :("

Pros: "Flight from Calgary to Chicago was excellent!"

Pros: "Nothing"
Cons: "It was awful. Flight was delayed for 3 hours because united couldn't get a pilot here who was even coming from a warm weather destination so weather shouldn't have been a problem. Poor planning. There was another flight I tried to get on but they couldn't seem to locate their flight attendants and it was delayed about 6 hours."

Pros: "Good time of day flight"
Cons: "Very cramped small plane"

Pros: "The directTV was great."

Pros: "Loved the Great Falls airport!! Who goes to an airport that has leather couches that you can lay down on and take a quick nap!! Beautiful airport!!"

Cons: "lost our bag, crying babies, uncomfortable plane"

Pros: "Everything was on time"

Pros: "Overall fine"

Cons: "Why should I have to pay to watch tv? I know you don't have to pay on Southwest, Virgin America or Jet Blue. Not sure that a very (and I mean VERY SMALL) snack can be considered food"

Pros: "American Airlines saved the day!"

Pros: "Excellent"

Pros: "On time"

Pros: "Same as above."
Cons: "Same as above."

Cons: "United airlines.. Terrible"

Cons: "When about to get on plane, carry on taken to checked bags; 5 people already on plane were required to come back off and check bags. I begged not to have to check because I was flying to Nicaragua and was worried my only bag would get lost. I was right -- it did not arrive in Nicaragua until the next day. We sat on runway for 45 minutes before departure so United could fix BOTH sets of the plane's wings lights. Why did they not discover that at any time BEFORE we all boarded or while we were boarding -- NOT first when deciding to pull away from gate. Delay caused many to miss connections."
