Pros: "Crew was great, check in was fast. Overall great experience."
Pros: "Seat was comfortable, boarding was good"
Cons: "WiFi didn’t work, my tv didn’t work either"
Cons: "Nothing, really. Airlines unfortunately can’t make people patient or polite, & I can’t afford a private jet, so I’ll have to settle for an eye roll or twelve."
Cons: "The food on the plain or snacks were to poor and not that tasty."
Pros: "The crew was very attentive and had great personality. They anticipated any needs we had."
Pros: "Comfort and service was great."
Cons: "The severe delays was frustrating and not getting enough information about it."
Pros: "The plane was nice"
Cons: "I’m still sitting in Minneapolis so I would have liked to be at my destination. And I had to pay for the overnight accommodations."

Pros: "Crew was friendly."
Cons: "Wish the seat was more comfortable. Landing was jittery and bumpy."
Pros: "Flight was smooth, arrived early..crew was prompt and courteous."

I went to lower my tray table and it was very nasty. Looks like some one had left some food on it and then just closed it up.

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."
Pros: "Boarding was quick and efficient. The aisle was nice and wide which makes walking to seats easier"
Cons: "Not the most comfortable seats"
Pros: "Punta Gorda was not over-busy. So the hassle level of the pre--flight experience was way down from the norm nowadays. The flight was on time, and only mostly full, not crowded."
Cons: "Not even water free infliight is a tad chintzy. Allegiant is not responsible for this, but the seat belt sign was on most of the time. I counld wish for better weather enroute. On arrival at ALB there was not video display announcing the belt numbers fror different arriving flights. One had to just drift from belt to belt"
Pros: "Nonstop flight. Wish it was available year round!"
Cons: "Our boarding and flight was delayed, but we were given no explanation."
Pros: "Crew was friendly, boarding process was easy, and the aisles are spacious"

Cons: "Didn’t leave on time. Would be nice to get something complimentary for all the wasted time. Would like to be able to watch something"
Pros: "When you land at Concord you are right near the parking lot!!!"

Cons: "Seat are extremely uncomfortable they are too small"

Pros: "Crew was nice and friendly. Pilots flew great. We arrived a few mins early as well."
Cons: "On the way to Denver from Miami we were on a nice new AA plane with TV entertainment, movies, power, and comfortable seats. On the way from Denver to Miami we were on an old plane with no entertainment and old uncomfortable seats. If this is going to be the case, charge me less up front as well. My daughter had a terrible time for a 4 hour flight."
Pros: "Overall I liked a little of everything such as the entertainment, staff friendliness, comfort etc."
Cons: "The food would be the one thing I didn’t like, there is only one option of a snack and it’s not very fulfilling."
Cons: "The male flight attendant was incredibly rude, kept hitting my arms with his body with zero apologies. No manners when taking food and drink orders. Did not seem like he liked his job and in a customer service atmosphere this was extremely disappointing."
Pros: "Got to San Antonio finally"
Cons: "Not having maintenance issues on the same flight from the prior flight to our airport then having more maintenance issues prior to leaving."
Pros: "I was able to change my seat."
Cons: "Five hour delay, no entertainment, no food... A really poor experience."
Pros: "Staff found us two seats together. Food was good."
Cons: "Email telling us about pre airport arrival check in and seat selection."
Cons: "The delay was horrible and the captain said it was because they needed extra sleep. I found this offensive as i was trying to complete a very long trip and was exhausted."
Pros: "We landed in NYC -- although it was first announced as Dulles."
Cons: "This flight was on Canadian Air under the auspices of United. I was not allowed into the United Club lounge despite the fact that I had business class ticket. I was informed that a business class ticket isn't sufficient for using the lounge when flying domestic. It is only good when flying international. They call that customer service. I generally avoid domestic airlines because of the customer service. The flight attendants were not happy to serve you. It's a small flight but they didn't even offer a snack -- you had to ask for it. And then they brought over a small basket with nuts, chips, candy bars, and a muffin. I took a muffin and it stuck to the roof of my mouth -- very poor quality. When I asked for a snack the flight attendant replied cocktail or soft drink never saying whether or not a snack was available.. She said this a couple of times before I could repeat that I wanted a snack to which she replied you want something to drink with that. I've been on many short flights in Asia and they will deliver a full meal and you don't have to ask for it. There was no entertainment but United did send an email explaining how I could purchase entertainment to play on my own device."
Pros: "Flight was delayed by 3 hours. Hostess was super loud repeated destination at least 100 times."
Cons: "Pilot was calm and understanding"
Cons: "The flight was delayed by five hours due to a mechanical problem with the plane. Little information was provided by United. Frustrating experience."
Pros: "The flight attendants, service and comfort were very good."
Cons: "Because of plane maintenance the flight was 4 hours late. I stood in line for two hours to get my flight changed since I missed my connection in Frankfort, and never got it changed. I got to Frankfort and stood in 3 more lines to get on standby. I’m hoping to get to Naples before the last ferry to Capri in order to make my sister’s wedding."
Pros: "Quick flight, faster than schedule. Flight attendant was good."
Cons: "Absolutely no leg room or arm space in the seats on US express jets. If the flight were longer than an hour it would make for an absolutely miserable experience."
Pros: "Got a window seat and had an amazing crew. Everything went smoothly! Dinner and breakfast served!"
Cons: "Everything was perfect!"
Pros: "Nothing, 2 hrs delay waiting for a crew member and plane was ~25% full, no snacks or beverages"
Pros: "On time"
Cons: "Extremely high charge for carry-on baggage, extremely high charge for changing flight times, no beverage service, seats are very small with no iPhone charger available."
Cons: "It would take little effort for the flight attendant to say which terminal the baggage claim is. If she can say the carousel number, she can say the terminal number. Half the flight went to the wrong baggage claim and had to wait in the heat for the shuttle in order to get to the right one."
Pros: "The ride itself is more than you expect for the price."
Cons: "We had problems with our bookings that changed our plans no less than four times that day. The personnel were, however, as helpful as they could be and eventually got us home."
Cons: "I don't like the seats, they have no cushion and they don't recline. Plus the tray table is super small. Also you pay for all drinks. Another thing the pressure is horrible in these planes. It seems they try to cut down on cost so the cabin is not pressurized right to reduced your ears from getting the over pressure from the ascend and descent of the plane."
Pros: "Quick flight."
Cons: "The seats don't go back, but you get what you pay for last minute."
Pros: "Nothing really after paying $45 and l have to pay another $45 to go back to Cincinnati"
Cons: "Too much luggage fee $45 is too much"
Cons: "They say they are giving you a bargain but with fees it's absolutely the same as other airlines but with far more uncomfortable seats and no amenities. Will bnever fly never fly frontier again."
Pros: "They charge you for everything nothing is complimentary . The seats are super uncomfortable. No tvs can't recline. They want you to think your saving So much because the ticket is cheap but they end up charging you for literally everything else. They charge you for everything nothing is complimentary . The seats are super uncomfortable. No tvs can't recline. They want you to think your saving So much because the ticket is cheap but they end up charging you for literally everything else."
Cons: "They charge you for everything nothing is complimentary . The seats are super uncomfortable. No tvs can't recline. They want you to think your saving So much because the ticket is cheap but they end up charging you for literally everything else. Not worth it at all!!!"
Pros: "On time take off Price"
Cons: "Seats were so uncomfortable my neck and back hurt I paid to upgrade seats for more room I did no good to have more leg room in a terrible seat"
