Pros: "good, free movies"

Cons: "No seat room or real leg room and I am only 5’2”. No in- flight screens and unable to connect to WiFi even though I had the app already downloaded.

Years ago it was very unpleasant to fly Delta because of rude flight attendants especially on us domestic flights. Hopefully that has all changed. Especially the older crew. If they can’t stand doing better customer service they need to retire . Happy to fly Delta and will let people know."

Pros: "On Time"

Pros: "Very late flight. Left on time, arrived 25 minutes early! Cabin crew were friendly and cared for everybody's comfort. They distributed a lot of extra munchies. They had real almonds instead of the usual 1/3 ounce peanuts, isn't that wonderful? Lights went off early and stayed that way so that the passengers could easily sleep through the flight. Uneventful flight, and therefore enjoyable."
Cons: "I had chosen 10C in the Comfort+ section of this MD90 plane. I did get my knee bumped more than once. I still like the seat because I can stretch my legs, but people should be aware of the bumping issue; it can be rather painful, and you do not get an apology."

Cons: "My seating. Location. We checked in 22 hrs before the flight and received C4 c5"

Pros: "Relatively painless."
Cons: "I do not like the seating and the need to be on a regional jet for more than an hour. Delta should think about passenger comfort when they consider their bottom line. You'll lose me as a customer."

Pros: "Boarding was fast, seats were comfortable, flight was on time, crew very professional."
Cons: "The boarding area was dirty, and the gate changed twice, once when I was already in a different terminal, so having me to ride the shuttle twice. In general I hate to have to pay extras for baggage, seats and pedale food. This is not AA specific, but if AA would lead change I believe it would soar in 1st place for customer satisfaction."

Cons: "The bathroom supplies were not replenished. In fact, the facial tissue was empty at beginning of flight. When the toilet paper ran out, I finally informed the attendant and they fixed everything. It seems that checking on that stuff was not part of their routine."

Cons: "We had too little time to switch flights. We were stressed and had to run a lot in order to make it to required connecting flight"

Cons: "It took a while day to get our bags after they decided to put it on the next flight"

Cons: "This agent spent 30+ min to check us in through a connection flight to Seattle. He couldn't find my wife's reservation, when it should be in the same reservation as me. He tried 5 times, and still failed. Later we found out at the gate that he was using the wrong name (same last name, different first name). Luckily the American Airline agent at the gate was more than competent and efficient to correct the issue in 5 min."

Cons: "Dry / borderline rude staff and hostess. Dated plane. Tiny seats. But that is pretty much the baseline of airlines in the US. When will carriers start to take note from International carriers..leaps and bounds ahead."

Cons: "close it!"

Pros: "Long walk and less than an hour. Very difficult for senior. No assistan e available."
Cons: "The pain from carrying bag between gates"

Pros: "Excellent crew."
Cons: "Obese people should have to declare their weight and pay for two seats."

Pros: "It was effortless... easy boarding and accommodating crew. There was a lot of turbulence so only one beverage service and no food. Would rather be safe than have crew injured."

Cons: "Longer flights should have screens in the headrests"

Cons: "Bad as above"

Cons: "Going through immigration in Dallas is a disaster. The wait is eternal. None-US passengers seemed to get processed faster."

Cons: "The crew was talking very loudly so I couldn't sleep. It's a red eye flight! People are trying to sleep!!"

Cons: "2 different attendants spilled drinks all over me and my carry on"

Cons: "Never made it because first leg was canceled"

Pros: "Flight was canceled due to maintenance problem, American claimed rebooking was someone else's responsibility. I had to talk to 4 people before they rescheduled me for the next day. American's gates/terminals at LAX are also a pain--you never know if your flight will depart from the hinterlands of Tom Bradley terminal, or Terminal 4 or 6, which can mess you up with parking/security screening/scheduling. I will try to avoid flying American in the future. I didn't get any vouchers for the cancellation, either. BD"

Pros: "Great service. Lots of legroom"
Cons: "None"

Pros: "Was called ahead of time to e alerted to flight delay. But I'm still never flying American again due to the rudeness of the crew."
Cons: "We're asked at the gate to measure our luggage. We did, and while it fit, the material of the bag made it look bulky (but upon touch, it was clearly not a full bag). When we said that it fit; the woman literally just scoffed, said "no" rudely, and walked away. We were polite, so why the rudeness?!! Never again AA."

Pros: "Nothing...I had to be rerouted to Chicago to Seattle!"
Cons: "The fact that through no fault of my own, I arrived in Seattle much later than expected and my clients were not particularly happy with the delay."

Pros: "Nothing!!! WORST EXPERIENCE IVE HAD TRAVELING"
Cons: "This was the worst day we have ever had flying. Spent 12 plus hours at the airport! Got on and off planes for 6 hours because of mechanical problems. 7 hours later they canceled the flight due to crew fatigue. The customer service was horrible plane was dirty it was an horrific experience. Alaska booked us with American Airlines. I will never travel American ever again. I'm considering using a different booking site. The experience was the worst I've ever had. Kayak Alaska and American are getting bad marks from me!!!!"

Pros: "The plane was luxurious and comfortable, even in coach. Great flight."

Pros: "Nothing. Worst flight I’ve ever taken."
Cons: "We were on the tarmac for 3.5 hours with little communication or apology. The seats were very uncomfortable. Terrible turbulence. Not even a complimentary soda for all of this. I will never fly Allegiant ever again."

Pros: "No seat not comfortable."
Cons: "No legroom."

Pros: "I love that they fly out of smaller airports. I feel like the crew is kind and helpful."
Cons: "The seats are not very comfortable but luckily most of the flights are not too long."

Cons: "Reclinable seats"

Pros: "Great crew"

Pros: "The plane was clean and crew was very friendly."

Pros: "Crew food. Seat small little leg room."
Cons: "Plane on time. More leg room."

Pros: "I didn’t enjoy anything about this flight unfortunately it was my worst experience with an airline that I’ve ever had."
Cons: "I had checked my bag with was a personal bag and they said it fit inside the metal stand they had so when I proceeded to board another lady had told me I’d pay $50 or wouldn’t get on. She was very rude she let me friend with two bags go on without paying. I took four flights and never had this issue"

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

Cons: "Very uncomfortable"

Cons: "There was no way for us to add another bag after our seat placement. No one answered the phone for Alligent and the website didn’t work. It costs $20 extra to do this at the airport. Even though it was not our fault that there was no one answering phone calls (and no way to leave a message)"

Cons: "Check in."

Pros: "Definitely the price. Boarding process was pretty quick. Flight attendants seemed nice."
Cons: "Left a little late, but still arrived on time, so that was okay. Seats aren't the most comfortable, but that's expected. Was still able to get a little nap in."

Pros: "Price"
Cons: "Runs late but no updated to arrival board, the attendant was rude when asked what time they thought the plane might be leaving."

Cons: "The airports restaurants closed and security shut down as well. We were prisoners in the airport with only a vending machine. Unbelievable. Believe the Allegiant Air stories from 60 Minutes. The stories are true."

Pros: "Crew was very friendly, very polite unlike the United flights I have taken. I was told the space would be uncomfortable but it was absolutely fine for the short flight."
Cons: "No beverage service. Not even water is offered."

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: "Friendly staff!!"
Cons: "Hour delay on flight"

Pros: "It was exceervice"

Pros: "On time and very efficient"

Pros: "The price was unbeatable, especially if you don't pay for a checked bag, carry-on, or a soda on the flight. Very smooth flight as well."
Cons: "The plane interior looks like it was gutted, then fitted with hard, plastic seats. No headrests, no privacy for the flight attendants. Everything costs extra."

Cons: "Left/ arived 30" late"

Cons: "No compliment"

Pros: "I arrived safely Tommy Destination"
Cons: "It was so hot boarding and unloading. There was no air. Staff was curt and not very friendly as of assistance."

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

Pros: "I liked that they had a direct flight from Los Angeles to Bellingham."
Cons: "The delays were horrendous and a google search reveals this to be so common it makes me wonder if it's not part of their business model. Like, so bad I ended up booking a return flight on Alaska and just ate the extra $300."

Pros: "Well-priced. Good seat spacing and aisle size, good atmosphere. Easy to find overhead storage and boarding is quite fast and well organised."
Cons: "No complementary drinks, no TV to watch. Which is fine since those aren't necessary, but it's good to know if that's something you're willing to pay extra for."

Pros: "Very comfortable; flight crew very professional."
Cons: "Getting off late - but this was due to a storm, so I am happy that the decision was made not to take off on time."

Pros: "Nothing. We were scheduled to fly back to Vegas at 7:07 then delayed to 8:30 then 10 pm then 11:25 pm now 1:15 am. This is unbelievable, unacceptable and ridiculous! And I have to work the next day. This is unacceptable! I just received another update that now we're leaving at 1:45 am . Please do not, again do not use Allegheny EVER again!!"
Cons: "So many delays. This airline is unreliable, unprofessional! Ridiculous! Please read my comments above. Do not use Allegiant!"

Pros: "Best flight for its Price. It was on time."

Pros: "Flight cost."

Pros: "Seats were clean and nice"
Cons: "One crew member clearly is a disgruntled employee. It also should be against the law not to provide water without payment."

Pros: "The fight"
Cons: "Security"

Pros: "Arrived an hour before flight. Check in took 25 min and tsa 30 minutes. Tried to go through expedite line but agent refused to let me even though flight was leaving in 30 minutes. I have received better treatment in new York airports than here in Myrtle Beach. Who would have thought. There were 3 others that missed the flight. Why would they not just let's be expedited?"
Cons: "See above"

Cons: "No leg room!"

Pros: "On time. Easy boarding and off loading. Nice staff"
Cons: "The seat. The people. The drinks. The efficiency. The price."

Cons: "Aircraft cabin was a bit dirty"

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."

Pros: "The price"
Cons: "Everything"

Pros: "We had kids wound up from Disney and caused all kinds of problems. Normally the attendants are irritated, every single one of these remained genuinely polite. I really thought the staff/crew were great. Other than that the flight was fine, a little late, but all went well."

Pros: "pleasant flight got there and back safely"

Cons: "Small plane for a 6+ hour flight, food is . sub standard, if you want to watch the onboard entertainment you need to do so from you phone or Ipad, you need their app installed first and flash player, if not your screwed. They allow you to download their flash player but it does not work."

Pros: "Everything was great except for the food."
Cons: "The hamburger bun was hard as a rock."

Pros: "Every day they take more away from us....the paying customer. ALL major carriers are becoming LCC ( low cost carriers ). Are there no real domestic airlines left. I REALLY miss Continental."
Cons: "I used to enjoy flying. Now I dtead it. There is NOTHING to look forward to. These days you get to pick lhe lesser of all evils. Is there an airline out there that REALLY wants me as a customer???"

Pros: "On time"

Pros: "Service and flighr smooth"

Cons: "Delays"

Pros: "I arrived safely."

Pros: "Great service and food"

Cons: "Showed up at airport w 2 15 yr olds traveling alone. We're told we needed to pay $150 each way. We were NOT told when tix were purchased. Accused of lying about the girls ages when we booked. Tix were booked and paid by two different parents and times. Agent relented and waived fee. At the gate we were again challenged and had to go thru it all again. No more United for us!"

Cons: "Confusions on dates from Internet. Your site usually sets its own dates without confirming."

Cons: "delayed"

Cons: "Charge for tv!"
