Cons: "Smooth on time flight"
Pros: "The seats were ok."
Cons: "The flight was delayed over 3 hours so I missed my connection in Chicago to Seattle. I’m now stick in Chicago overnight and have to be on a 6 am flight tomorrow. The Delta staff at LaGuaurdia was extremely rude and not helpful at all. Hate Delta......"
Pros: "Flight left on time"
Cons: "Gate crew had trouble identyfing boarding pass on their computer. Difficulty getting on plane"
Pros: "Fast boarding, friendly crew, and comfy seats"
Cons: "It was pretty bumpy and a few times we changed altitude very quickly"
Pros: "I loved the flight attendants and the desk staff everyone was so friendly and made me want to travel delta again."
Cons: "Delta doesn’t offer military spouses free checked bags and I found this out at the airport. It was disheartening, but at least it’s Delta and not the airline that is supposed to represent America."
Pros: "On time/ early arrival!"
Cons: "Most bring on 2 large carry ons slowing down boarding an de- planeing."
Cons: "Plane journey awful. Speaker had a loud buzzing noise all the time so never heard a word bad landing. Rattling plane Very cold."
Pros: "Clean plane, the seat felt roomy. Smooth ride and the captain communicated clearly."
Cons: "It felt super hot and I wish there was food included in such a long flight."
Pros: "Quick flight"
Cons: "Flight attendant spoke like a robot. Could not understand her."
Pros: "On time"
Cons: "Small aircraft"
Pros: "Staff, service, options"
Cons: "Over an hour delay before boarding due to supposedly bad weather. Because flight was overbooked they were offering $400 gift card to change to standby on another flight. If you didn’t make that flight (evening), you’d be confirmed on a flight the following morning with one stop in Detroit (we booked a nonstop to Chicago). Uh, no thanks. Then to top it off, we’ve landed and been told that it will be at least an hour before we can deplane due to no availability at the gate (it’s 1145 pm right now). All this plus their new policy of not allowing us to select our seats because we bought the cheapest tickets. Really Delta? You go ahead and cater to the rich and I’ll choose to fly with another airline."
Pros: "Crew friendly"
Cons: "Middle seat with no option for me to move"
Pros: "Movie"
Cons: "Break downs again... At least this time they found another plane."
Pros: "Flight attendants were pleasant."
Pros: "Friendly service, comfortable seat, on time, no issues."
Cons: "Everything"
Pros: "The crew was great"
Cons: "The flight was 4 hours delayed"
Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."
Pros: "Friendly staff and comfortable seating"
Pros: "This was not my original transfer flight but everyone was much nicer and helpful than serious and being rude. Love Delta, I did not flight United because I wouldn’t have met my United flight once landing in ATL. The Young African American woman who was at the gate was amazing and so reassuring that I would make my flight to Chicago. Would book Delta, just because of how nice she was to me."
Pros: "i liked that staff and crew were very communicative and pleasant."
Cons: "one crew member didn't show up and caused delayed flight."
Pros: "Flight was on time. Boarded quickly with no fuss."
Pros: "Flt on time, very nice and friendly gate agent and flight attendant"
Cons: "Too tight and seats not comfortable."
Pros: "The Delta people were solicitous, efficient and brilliant the whole way through. We had not a bit of trouble. Our first class seats were comfortable, but with the supplied blanket, pillow and poor air conditioning it was a hot flight. The cabin personnel were wonderful as per usual, and my tasty gin and tonic soothed any discontent. I wish I could fly this way all the time!"
Cons: "The private contractor handling wheelchair assistance was terrible. A Delta employee theorized that they do not pay enough to attract and retain personnel. Our pre-arranged chair was not there, multiple calls by our Delta assistant finally got us a ride to the chair holding area, but after about 45 minutes we gave up and shuffled off to the security area on foot. Thank goodness my hubby is mobile enough for that to have been an option. When we abandoned our wait we were still 4th in line for an attendant to push the chair. If Delta has any responsibility in this it would be in the retention and compensation for the private contractor."
Cons: "The delta studio didn't work with Android 8"
Pros: "We were traveling with a toddler and infant but put in different row because the tickets were purchased separately. Gate staff promptly put us together and even bumped us up to delta comfort. Was a very pleasant trip. Thanks delta!"
Pros: "Plane arrived early"
Cons: "They board the front of the plane first, meaning the aisles get clogged up slowing down the process. Also, staff kept insisting pre boarding that more people needed to check their bags because there wasn't enough overhead bin space, but there were plenty of bins not full by take off."
Pros: "Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league."
Pros: "Airline stewards were very friendly and pleasant."
Cons: "We booked with Delta, but were put on Air France. Even though we had our boarding passes in hand we had to wait in long, slow line for baggage tags because they would not print from kiosk. There was minimal Air France staff on duty serving thousands of passengers during busy season (July). While the lines grew larger, the staff was reduced from 4 to 2. Another long, slow line for customs, another long slow line for security=Charles De Gaulle airport was awful. We arrived at the airport 4 hours before our departure time and got to our boarding gate with no time to spare."
Cons: "Very uncomfortable, seats did not recline and seats way too close together."
Pros: "Entertainment options weren't bad. Most of the crew was polite other than one flight attendant who seemed ambivalent and unhappy to be there."
Cons: "Three hour+ flight and just one tiny bag of pretzels? And no lemon or lime wedges on the beverage cart? Plus, I have to pay extra for one checked bag. I will only fly Delta if I have to in the future. Subpar airline."
Pros: "What I liked: Sky Priority privilege came with separate luggage check-in queues and early boarding"
Cons: "What I disliked: Seats were too small No beverages or snacks offered No USB or power outlets available Three different groups board before Delta Comfort (e.g. those needing more time, travelers with children, first/business class) Didn't see the value compared to a less expensive main cabin ticket"
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: "Absolutely GREAT!!!"
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: "Friendly crew."
Pros: "Space Seating Hospitality"
Cons: "Maybe complementary snacks"
Pros: "Good pilots"
Pros: "Great crew"

Pros: "Cost of reservation"
Cons: "Expensive extras (added up to more than a flight on another airline would have been)- carry-ons, in-flight snacks and drinks, etc."
Pros: "The crew was very nice and professional. Seats were as comfortable as they can be"
Cons: "I really didn't have any problems , very pleased with the airline"
Pros: "Crew was good, quite friendly and helpful. Seats are a bit uncomfortable but what airline isn't."

Cons: "Seats do not recline, so not real comfortable."
Pros: "Quick flight and overall nice crew."
Cons: "None"
Pros: "Keep the free snacks and drinks, NA or soda, I really just miss the legroom (nearly 6’ tall) and cushions, a chair that can ease back a bit. All airlines do this but you are worse than frontier, the major carriers have skimped but not like this."
Cons: "3 hour torture chamber. When she said it was their goal to make us comfortable, but more importantly to keep us safe I snorted laughter. It was a bit better and a lot shorter than the dark passage"
Pros: "Affordable and fast"
Cons: "Big guy sitting next to me took up 2 seats!!"
Pros: "Smaller airports make travel easier, and more relaxed. No frills--to get even water on the flight you'll pay for a bottle. Personnel all tend to be friendly and helpful. With Allegiant I've learned to pack lightly and plan travel carefully. It's been worth it as I have been able to see friends and family more often. We even took an impromptu vacation this year when we found a great deal on airfare."
Pros: "The staff is always helpful and flights are comfortable."
Pros: "Cheap."
Cons: "Both departing and return flights were delayed by just over 5 hours."
Pros: "Plane was late. 2 years ago it was late and while there at the airport I heard Allgeant routine runs hours late or cancels. 3-4 hours, not an hour. Good thing I dont fly too often"
Pros: "Flight went smooth"
Cons: "I checked into my flight with luggage to check in. The lady behind the counter said I could not check my luggage that the only way for it to get on the plane was to take it through the TSA checkpoint. They confiscated everything in my bag that was over 3oz which was quite a bit of stuff hence the reason why I was trying to check it in. I will not be flying Allegiant air again."
Cons: "Flight delayed 3 hours coming in and 5 hours going back. This is unacceptable. I will never fly Allegiant Airlines again."
Pros: "This flight was a return to airline travel in the 1980s in a good way! The plane was clean. The seats are among the most generous seats today. The best and brightest surprise was that each flight attendant was genuinely polite and welcoming."
Pros: "Comfort and speed of the flight. Attentive staff!"
Cons: "Need one craft beer"
Pros: "Everything was good"
Cons: "Could of had more selections on the flight for snacks"
Cons: "I didn't like all the inconsistent additional fees, the reschedule, the delays, and gate swaps."
Pros: "Low cost, great service, arrived 20 min early"
Cons: "Seats were kinda tight but I'm sort of used to that"
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"
Pros: "flight took off on time"
Pros: "Very smooth ride and attentive friendly staff"
Cons: "Snacks were over charged."
Pros: "I understand the need to make a profit but comfort is probably the most important aspect of any flight......"

Pros: "The price."
Cons: "Having then bill me for each little thing."
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: "Nothing about it at all"
Cons: "I didn't like the turbalance on the plane I didn't like the service check in line Need more people helping in the airport"

Cons: "nothing"
Pros: "Wheels up to wheels down took under 20 minutes."
Cons: "I'm 6'4" and if I would've had to sit on that plane much longer I would've been quite sore. Seats are small, space is exceedingly limited. But, it was a regional jet, so this was to be expected. Nonetheless, other airlines' regional jets haven't been quite so cramped."
