Pros: "Movies and usb charging"
Cons: "4 hour flight and all we get is a cookie?"

Cons: "No se diferecia de otras lideas aereas en decadencia."

Cons: "More leg room and seat width. I don’t like having other passengers pressed against me."

Pros: "Flight was on time, smooth take-off and landing, and gluten-free meal available (ordered before through Delta.com). Alcohol was available at each drink service."
Cons: "No gluten-free snacks, lack of gluten-free awareness by crew, and gluten-free meal had an apple instead of the (gluten-free) ice cream bar the other meals included for the dessert."

Pros: "Didn’t like security. They were rude"
Cons: "Security"

Pros: "The gate agents were nice enough."
Cons: "We sat on the tarmac for an hour without information as to why we were delayed. We missed our connection in Atlanta, even though we arrived at the gate in time to see the gate agent shut the door while we were running and waving. We arrived at the gate 8 minutes before the flight departure time also. The flight attendant on the flight from Fayetteville just handed out water and cookies without asking what you wanted. She had coffee and snack mix but didn’t ask anyone, just handed them what they got. Overall I was very disappointed in the flight from Fayetteville, NC to Atlanta and with the gate agents at the Atlanta airport. I usually expect more from delta. They didn’t offer vouchers to make up for the missed connection or offer to pay for a hotel since the next flight out was the next morning."

Pros: "I had the chicken beans and rice which was good, the chicken burrito was a little soggy and had to peal it out of the box but taste ok."
Cons: "The choice of the movies were either action or kids movies, i would like to see some sports movies, auto race, football or espn. All of the was energetic with great smiles and service except for one that never smiled and lacked enthusiasm. I wondered why she was on the plane."

Cons: "At least one hour late"

Pros: "I did get home eventually"
Cons: "Flight was delayed. Seats are cramped."

Pros: "I liked the cookies and juice. The interactive screen to watch something. The cleanliness. The price. On time. The service. Thank you. The excitement of flying."

Pros: "Flight crew was excellent. We had the emergency exit row so leg room was awesome! Kind bar and soda we good."
Cons: "Flight delay due to the older aircraft and lack of a pilot that knew how to fly it. Bathroom needed some tending to"

Pros: "Equipment felt a bit dated. No entertainment system, which was fine with me. Skipped the offered snack. Just had water. Flight was onntime."

Pros: "I will say that this has been the best flight my husband and I have ever had. The crew members were very nice and helpful. This has been the smoothest flight we have ever had as well."

Pros: "Food was unexpectedly good."
Cons: "The flight was delayed for 40 minutes. We could hardly catch connecting flight"

Pros: "Snack"
Cons: "I was delayed over 2 hours"

Pros: "The Dutch flight attendant who took care of our economy side of the flight was personable, helpful, and cheerful. She made the flight definitely more pleasant because as you know, traveling overseas in economy is no picnic!"

Pros: "The crew at the airport was very courteous and helpful."
Cons: "No food; not even offered water; I asked a Delta employee about our seats and she was very unprofessional (mind you I'm traveling with kids and my boarding pass said that seats were to be assigned at the gate)."

Pros: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos, please reimburse on the credit card"
Cons: "I can’t make it in mexico city on tuesday, wednesday’s performance had to be cancelled and we need to pay the cancellation fee 11500 mexican pesos of the studio and musicians"

Cons: "This wasn't pertaining to the flight or airline; but the TSA line was ridiculously slow."

Cons: "Delayed due to problem with the door"

Cons: "I loved it all."

Pros: "Good choice of video programs."
Cons: "The flight attendant took 25 minutes to appear, and had enough time for one round of service. First class, at least you should get two drinks. Fly basic economy, there just isn’t any reason to fly first class."

Cons: "Direct flight, on time arrival"

Pros: "i fell asleep until we arrive to STL."

Pros: "Once aboard, flight went without a hitch and flight crew was attentive"
Cons: "The inflight entertainment options need to be expanded - I've run out of movies that I want to watch!!!"

Cons: "It was announced that there would be lunch shortly after takeoff and then a snack about 2 hours before landing. The lunch was ok, but then the snack (multiple small items) was offered about 4 hours before landing and then an additional snack (mini pot pie) was offered about 2 hrs before landing. This is too much action for people who are trying to get some sleep. Also, abrupt and hard landing."

Pros: "I got to destination. Baggage claim was quick."
Cons: "Flight was delayed due to waiting for a tardy flight attendant. Landing felt a little hard. No announcement about baggage carousel prior to disembarking."

Pros: "For a short-haul flight on a small CRJ, it was the most pleasing and comfortable flight. No delays and everyone was pleasant from ground staff to flight crew."

Pros: "The flight attendant. Lovely and professional."

Pros: "on time"

Pros: "Great (seemed like unusually friendly and helpful) crew. Plenty of carry on baggage room."

Pros: "Did not eat or use entertainment."

Pros: "I love that I was upgraded to first class!"

Pros: "Everything was smooth. Short flight, but they offered us refills on drinks, which I've never experienced before. Polite staff, great flight. Thanks!"

Cons: "Delta allowed us to board knowing of possible weather delays at the destination! Once on board the captain announced that we could not take off due to weather at the destination! Why didn't they let us just sit in the airport until Delta knew one way or another? Been sitting, trapped in the plane, no AC, no announcement from the flight crew. Could be waiting in relative comfort inside the airport!!"

Pros: "Free movies & TV for all seats and the selection is great! Also, used the wifi and had great connection the entire flight."

Pros: "Excellent flight. Nice new aircraft."

Pros: "The crew was nice"
Cons: "I didn't like the fact that I didn't get my luggage with me when I arrived to casablanca as I lived 4 hours away from the casablanca. I have to come back the next day to get my luggage. I was very mad about it.plus I noticed one of my luggage has been damaged so now I have to buy another one because I can t use it. It was disgusting."

Pros: "The employees dealing with this whole nationwide fiasco were largely very helpful. I could tell that some were running on not enough sleep, but the customer service was good."
Cons: "My flight leaving at 9am was cancelled, and after missing out on 3 different standby flights, I finally got to my destination at 3am (4am central). My coworker had the same cancellation and got to our destination about 6hrs earlier through a connection. I wasn't told about that option and I could've gotten an actual night of sleep."

Pros: "The flight crew was nice and polite. They served drinks and snacks in a timely manner while on the flight."
Cons: "Flight was scheduled to leave early, the plane arrived, but they couldn't turn the plane around fast enough. We left the gat late, then pilot said we would still be arriving half an hour early. We arrived about 45 minutes late, and that was a problem because our connecting flight was due to depart now in 15 minutes. Lightning forced the airport to shutdown, which was great, we had a chance to catch our flight, but we were stuck in the airplane, and we couldn't get to our gate until the all-clear. I know this is not Delta's fault, but they did arrive quite late on a flight that, according to them, would be early. They also never communicated to the other flight that there were several passengers catching that connection. So by the time we had ran to catch our connection they had closed the ramp. Lightning hit again, and they shutdown the airport once again, so the airplane was still at the gate for about an hour, and they did not allow the 20+ passengers to board that plane, which was right there. So frustrating. The only thing that saved it was that our new flight was the new airbus, and although it left an hour and a half later, the comfort level was phenomenal."

Pros: "Crew service was excellent"
Cons: "Poor leg space"

Pros: "On time, nice crew."

Cons: "I booked with Delta who doesnt give you limits of weight for the carryon...why since the flight was operated from Airfrance they gave me limits of weight of 12 kg??? one ticket one law pls again, the hostess in my row was very nice, even the steward who was working with her very snob...it's not his job"

Cons: "6 hour delay due to part that St. Louis sent for - twice. Will never fly through ST Louis again on AA. Terrible Domino's pizza and water were complimentary after 4 hours delay. Returned to gate twice. 11 a.m. flight arrived at 9:30 PM ( 3 hr flight). Poor gate attendant was left to fend for herself as she was fed false and contradictory information."

Pros: "Busy but kind stewardesses"

I waited at the baggage carousel 15 minutes for my bag after over an hour delay due to switching aircrafts. With a flight arriving this late in the evening with the low volume of bags checked (due to checked luggage charges), this should not be the case. Five minutes to gulp down ginger ale."

Pros: "Crew was awesome!"
Cons: "It was a great flight!"

Pros: "They sat my family together and the crew was amazing."

Cons: "Should offer free water at least."

Pros: "Nothing really"
Cons: "Depart on time Not Loose my luggage Track all luggage every step of the way instead of crisis management only when a lost luggage claim is filed"

Very disappointed customer as I have traveled with Allegiant many times and the one time I try to cancel my flight, I’m told I have to pay a fee which was more expensive than the actual price of the ticket. Waste of money."

Cons: "Nothing"

Cons: "The plane was filthy. It made me sick thinking that im stuck on this plane that they never clean..in the peak of sick season."

Pros: "On time"
Cons: "Crew unfriendly, sometimes rude"

Cons: "initially assigned to center seat."

Pros: "The crew was friendly and smiled a lot. Non stop flight from easy and for me, convenient airports. I knew food cost extra so i brought my own."
Cons: "I knew my comfort would be cramped so that was expected. My only complaint was we couldn't understand the boarding instructions at the gate when they were calling zones. The microphone stunk! So because we couldn't understand,, people got in line who shouldn't have yet, and others didn't get in line that should have which seemed to really annoy some mouthy jerk in zone 5....who then had to turn around while boarding bc he forgot his phone, lol. Karma. So, that was my only entertainment and it was pretty great."

Pros: "Nothing."
Cons: "The flight was delayed by hours, with no explanation given. It was coming from Florida, with no bad weather in between. It caused us to arrive at 1 am."

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."

Pros: "People in my row."

Pros: "direct flight"
Cons: "EVERYTHING is extra payment, even a small carry-on; water $2!!!; seating is extremely cramped"

Pros: "Excellent value. They had hard time with the head count which delayed our take off. Arrived just a few minutes Late."

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."

Pros: "- Good price, even with carry-on and larger seat. - Comfortable seats, despite no incline - better than major airlines."

Pros: "Cabin crew was very helpful and polite. One in particular expressed a great sense of humor throughout the flight and had a great rapport w/ passengers. Flight was on-time. Fare was $111 compared to around $375 to Orlando. I was able to fit this flight into my scheduled so saved the company $$."
Cons: "Can't blame Allegiant for a noisy child, but there was a child across the aisle from me who shrieked and talked loudly THE WHOLE FLIGHT. I was trying to sleep and was NOT pleased. I like a good fare, but selling a can of Coke on the flight for $2 seems a bit extreme. Glad there are cut-rate airlines out there as an option, but I won't be flying them any more than necessary."

Cons: "They arrive to the airport over an hour early and went to the desk we're asking them to print my ticket they informed me that they cannot check me in at the desk I had to do it online I didn't have the ability to do that so therefore I miss my plane"

Pros: "Smooth flight"

Pros: "comfortable and on time"

Pros: "Happy people"

Pros: "Dr usus I"
Cons: "The keys"

Pros: "The seating was comfortable. On the Chicago keg I was seated in the middle and was not stuck with people who were too big for the seat. I noticed there was an overweight person in first class. Does United have strict policies on size?"

Pros: "Aisle seat."
Cons: "They made my dad check his bag even though there was space."

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: "on-time! Even a little early!"

Pros: "By bag was broken when I got to my final destination. It looked like they played football with it. I'm filing a claim with United Airlines"

Pros: "Please address the lax enforcement of one carry-on and one under-the-seat bag/passenger."
Cons: "Overhead compartments were full by the time I boarded so my bag was taken and tagged, as was several other passengers. I noticed upon arrival in Hartford that several passengers had 2 bags in the overhead compartment and their coats as well. If you have a policy of one carry-on and one under-the-seat/passenger, why isn't this enforced? It is not fair to the Group 4 and 5 passengers that there is no room in the overhead compartments and they are forced to relinquish their bags. Furthermore, this results in them having to go to the baggage claim area and wait for their carry-on. This added a half hour to my time and my ride had to circle the airport waiting for me to come out."

Pros: "Overall I arrived at my final destination in one piece. I'm satisfied :)"

Pros: ":("
Cons: ":("

Cons: "The airline checkin is terrible and time consuming!"

Cons: "Never made it because of stupid United"
