Cons: "Delta.... they’rrrrrr Grrrreaaate!"

Pros: "Most of the crew was great with the exception of curbside check-in in Denver."
Cons: "Curbside needs to stop chasing cash tips and do their jobs. If they focused on that tips would be easy to come by. The curbside attendant that took my bag didn’t even bother to check my id. He asked me my name and asked where my destination was. I told him Cincinnati as a layover then LaGuardia where he said that was wrong. He then proceeded to print a boarding pass that wasn’t mine and load my bag into the conveyor. Not 5 mins go by when I realize what happened I wound up having to go to special services to rectify the situation. Which ultimately consisted of me waiting another hour in LaGuardia to get my bag. Please delta have these curbside handlers actually want to do their job and stop chasing cash tips."

Pros: "Nothing!!"
Cons: "Delta is terrible!!! $100 extra for everything!!! Terrible!!"

Pros: "Everyone was fairly friendly"
Cons: "Cramped foot room"

Cons: "The seat I was assigned did NOT recline !!! I have neck and back problems and I was in so much pain. You need to clearly indicate when a seat does not recline ( as in exit row seats, which are clearly indicated)."

Cons: "Bags never arrived at the listed baggage claim. After 45 min, I saw bags on a different claim station and I notified everyone standing around. BUT, I filed a claim with Delta and was immediately given 2500 miles, as guaranteed!"

Pros: "Easy boarding, not a full flight, had plenty of room to stretch out, friendly flight crew, extra snacks!"
Cons: "Not much to say I didn't like, few problems with in-flight WiFi but otherwise good."

Pros: "Delta is great"

Cons: "The crew forgot to turn the heater on in -3°F creating a situation where the lavatory water lines froze. This caused a two hour delay which made me miss the second leg. Because I missed the second leg I was put on the very last flight out of ATL and got to spend Xmas eve in the airport."

Pros: "Nothing"
Cons: "Let me just say that I’m a loyal Delta costumer until now. The flight attendants (the two women) were an absolute nightmare. They were so rude and condescending. I was carrying with me my service dog and a bag containing an expensive medication (it couldn’t go on the top bin). Despite being in the comfort class and having the seat next to me empty, we were tight for space. The flight attendants were unreasonable and forced me to put my medication on the top bin despite the fact I had told them it was extremely delicate, that it that to go upright, and that I needed to keep it with me. They did not listen and pressured me into giving them the medication. The medication could have easily gotten broken. Thankfully it didn’t but this is no way to treat a human being."

Pros: "What a city.. Unique for hell sure..."
Cons: "Nothing"

Pros: "Boarding super excellent! Also: Best landing I've ever experienced! Props to the pilot!!"

Pros: "Newer plane with movies."
Cons: "Airlines pack you on so tight."

Pros: "Good food and entertainment choices on board. Little to no feedback from captain regarding inflight turbulence."
Cons: "Getting through security at the LAX Delta Terminal 2 was chaotic and the slowest I have ever encountered. There were two lines which moved at very different speeds. My husband got through his line 15min before I was finished in the other line. One line required iPads to be other, the other didn't. Something was seriously wrong with how things were being handled. Bathrooms onboard were a pigstie."

Pros: "On time"

Pros: "The moviea"
Cons: "The time of night"

Cons: "Cancelled my flight then re-booked me for the next day; was able to then find a flight same day but 7 hours later. That then was delayed another 4 hours and I had to buy a rental car to drive home instead. Thus far they have been unresponsive in getting me a refund for my travel. Don't fly Delta."

Pros: "I didn't like anything because the fly leat 3 hours"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "delayed. equipment failure."

Pros: "Timely departure."
Cons: "My daughter was traveling alone (as a college freshman) for the second time and her bag was overweight. The counter agent was impatient with her and made her feel embarrassed"

Cons: "I drove 5 hours to get to the airport and unfortunately ended up delayed because of traffic and slow shuttles from parking. I arrived 1 hour before the flight, but security was so slow I didn't get to the gat until 10 minutes before arrival. There were no gate agents present and despite banging on the gateway door and other Delta agents at the adjacent gate, no one helped me. I can only surmise that they had already given away our seats, which were award tickets, GAINED BY BEING A LOYAL DELTA CUSTOMER. The gate agents were unapologetic and useless at rebooking, and I bought a ticket from Southwest instead. As i was trying to get to my sister's wedding, and repeatedly told the agents this, their behavior was particularly abominable. DELTA, YOU'VE LOST A LOYAL CUSTOMER."

Cons: "Seats too close - I'm not that tall and my knees were jammed against the seat in front of me."

Cons: "I received an email on Tuesday night informing me that my Thursday am flight was cancelled, due to anticipated weather (no increment weather at the time), The email provided no instructions for rebooking except a phone number. I tried rebooking on the web site, but that didn't work. The web site did not know about the cancellation at all and wanted to charge me a large rebooking fee. Meanwhile I was on hold for two hours. Finally, I needed a midnight trip to the airport in order to rebook. At the airport, I witnessed ill-informed and stressed agents failing to cope with stressed stranded customers. One agent told a customer that she refused to help him any longer because he recorded her."

Pros: "cheap ticket"
Cons: "- Trays were about 10 inches wide and 5 inches deep - which provides no value whatsoever. You can't place anything on it b/c it's not big enough. - Chairs were short so I had nothing to rest my head on. - Cramped isle space"

Cons: "Lost luggage and delayed takeoff"

Cons: "Communication at the gate was poor. As well as the communication on board the plane."

Cons: "Flight attendant in the rear (on the flight to Denver)... Unpleasant nag. I'm fine with a no frills cattle car that affords 0 leg room and military cargo plane seats, just as long as it's reflected in the price, not the personnel."

Cons: "The day after arriving at our destination, our return trip was canceled: "due to day-of-travel flight cancellation or traveler no-show." I can assure you, we did show; I had the pictures. They tried to put us on an earlier flight, which was not convenient, due to travel plans made 8 months prior, so the return flight was scheduled for the next day (again, inconvenient, due to loss of income). Frontier attempted to charge me for the extra day. After I complained multiple times, they finally waived the additional charge when I reminded them I was NOT the one who canceled the original flight. My daughter and I were provided $100 travel vouchers, each, for the "inconvenience." Frontier can keep their $200."

Cons: "Let people know about their carry on luggage charges!"

Cons: "Baggage for 2 pieces of luggage $75.00 then a gimmicky Visa card to earn miles not cost effective"

Cons: "I was automatically bumped to a later flight because the flight I booked over a month ago was full. I don't like flying Frontier because the seats don't recline and other airlines seem to have friendlier staff."

Cons: "more than 2 hrs late"

Pros: "Not much"
Cons: "Horrible space No comp beverage No wifi No magazine Delayed"

Pros: "made it to DC"
Cons: "delayed 1.5 hours. little information. no apology. no explanation."

Cons: "3hour delay."

Pros: "It felt very simple and non complex, unlike other airlines where they make the process of traveling a long and tumultuous process. Bravo Frontier!"
Cons: "There was a Lady checking in people at the gate who had questioned many customers of whether their carry-on would fit, it seemed to bother many guests because they didn't want to be charged extra."

Cons: "The seats are by far the most uncomfortable I've ever sat in."

Cons: "Paying extra for EVERYTHING. Will never travel with Frontier again."

Cons: "Only food for purchase - did not buy any. No entertainment available, incl music. Seating crowded."

Pros: "Nothing"
Cons: "Everything"

Pros: "Early Arrival"
Cons: "Paying for a seat"

Pros: "except for the food and what entertainment it was over all good"
Cons: "could not pay cash"

Cons: "they cancelled the fligh on me - over booked"

Cons: "Your seats and absolutely terrible. What kind of an idiot designed them. Yes sure you added a few extra seats but the comfort level is horrible. I had so much back pain for sitting on those garden plastic chairs"

Cons: "They charged me 70 for bags.... Which is insane.... Without warning basically."
