Scores according to KAYAK customer reviews
Pros: "The accommodation to the military service members!"
Cons: "Air fresheners should be used on the airplane."
Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"
Cons: "Nothing all excellent"
Cons: "It was great! Nice job Delta !"
Cons: "Wouldn’t change a thing! I don’t always fly! But when I do!! I fly delta!!"
Pros: "Christina brown was amazing at gate"
Cons: "The main economy seats were far too narrow."
Pros: "The crew was great and the free entertainment was great"
Cons: "Bring back pillows and blankets especially on red eyes out of Anchorage"
Cons: "DTW to FLL, plane was delayed coming from BOS to DTW 5 hours for BOS weather. The plane arrived & they announced they would turn it around ASAP. They started the boarding process & then stopped it stating that a crew member had timed out. Delayed hour to FIND one. Shortly after delayed overnight."
Cons: "No meal option and my video screen volume did not work"
Pros: "Flight attendants were very friendly."
Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"
Pros: "great crew!"
Cons: "luggage. what a nightmare. I waited 30min for my luggage (after a delayed flight) only to be told by a fellow PASSENGER that some of our luggage was directed to a FRONTIER CAROUSEL. I then had to wait by that carousel till I found it. so much for "bags in 20min guaranteed""
Cons: "Boarding at JFK.Always messy"
Pros: "Inflight experience was fine. TVs didn’t work but Flight attendants are friendly on Delta, cramped seating - but not unlike other airlines."
Cons: "Regular fare seat assignment not available prior to gate . Airport concourse F - poor - limited services. Customer Service seemed uninterested and unable to provide service both on phone and at gate. I’m a frequent United flyer & today’s Delta service experience made me more loyal to UA."
Pros: "Early and middle seat was open!"
Cons: "Coffee tasted like fish. :("
Pros: "We boarded close to on time, no hassles. Allowed my husband and me (retired military) to board early, thank you."
Cons: "LAX security is awful. We never left the airport (arrived LAX from Sydney AU) yet were forced thru security again. Had to remove shoes, was scanned and "frisked" by TSA to get to Denver. To go to Australia, Denver TSA waived the removal of shoes, skipped the scan for the metal detector and no one touched me, ditto for LAX on the trip to Sydney. Where's the uniformity or standards for TSA?? Why did I have to be subjected to this garbage on the way home?? This is why I despise flying. It makes no sense to me. This ruined what was a great vacation."
Pros: "Not much. Boarding by "zone" works ok, but is no quicker than most other boarding methods."
Cons: "Boeing 767-400ER seats had no leg room for 6'+ traveller like me. The entertainment system was so old that there were no 115v outlets or USB ports. On a 7-hour flight, that is a significant problem for travellers today with multiple electronic devices. Finally, we were not told in advance that we had to go through security twice and through US Customs BEFORE leaving Dublin. So, the 6-hour layover at JFK was a complete waste of our time as we did not have to go through Customs there."
Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"
Cons: "My flight was delayed, which would have caused me to miss my connecting flight. The customer service person was not at all helpful, and told me there were no other flights available on any airline until the next day. However, I was able to go online and book another flight immediately...which means that she was either being disingenuous or actively undermining efforts to get me home in a timely fashion. Very disappointing and as a SkyMiles member would have thought there would be some level of common courtesy dealing with a non-weather related delay that drastically impacted my travel plans."
Pros: "Everyone who has a kid knows how challenging certain things can be in a flight and for me the combination of a night flight interrupting my baby’sschedule + a full flight it equalized disaster. My daughter could not get comfortable for the love of life and I just felt horrible and frustrated and what sucked most was the 9 year old and her obese father siting in our row that kept giving us weird looks."
Cons: "There’s NO room in planes between seats. It’s 2018 and new planes must be done ASAP to accommodate people better. I’m 5’1” and 110 lbs but adding my 25lb daughter siting in my lap before she turns 2 is absurd to expect that it will be comfortable whatsoever for us or the people breathing next to us. Please DELTA, lead by example and make sure your planes are designed with more room in between and around the seats. In my opinion, every seat should be first class."
Pros: "In a pinch they were able t"
Pros: "Everything was perfect !! Staff friendly"
Pros: "Good customer service"
Pros: "Great in every way"
Pros: "It got me home, eventually."
Cons: "Poor communication, a 6 hour delay followed by a 7 hour layover (during which we had to sleep on an airport floor because Delta couldn't offer us any hotel vouchers). Gate agents disappeared after 7pm becuase they were due to be done with their shifts when our flight was originally supposed to leave at 6 pm. It felt like we were trapped in the movie The Terminal. Oh! And our bag was misrouted, because that was just how things went those 2 days. All in all a 6 hour trip turned into 18 hours. I could have driven home in that amount of time!"
Cons: "Check in lines were crazy long"
Pros: "First leg from San Diego was excellent."
Cons: "Arriving in SLC discovered out flight to Denver was CANCELLED! Had to reschedule to the next day. Not fun!"
Pros: "The entertainment unit allowed me to watch the Denver Broncos game live which helped lessen the delayed departure and uncomfortable seating."
Cons: "Uncomfortable seating....too crowded!! We had a delayed departure by 30-40 minutes because of a computer download issue. Too many folks carrying carry-ons delayed boarding. I wish folks were not encouraged to go that route but to check baggage. This time of year gets even tougher with folks carrying Christmas presents and over sized personal items. Ugh. Not fun to travel this time of year."
Pros: "App is good and convenient to use."
Cons: "The app went down just as we were getting ready to board and luckily i had a printed pass and it took some extra time to check in."
Pros: "really helpful and friendly service and nice seats."
Cons: "We left late, it was delayed then maintenance issues. Twice. Seating was very tight and uncomfortable, no movies or entertainment at all. U.S. flights are the worst. Even on short flights with aeromexico outside the U.S. you get movies and food. Zero stars for comfort, food and entertainment."
Cons: "I don't like that I already completed this survey several days ago and have been receiving reminders to do so. I guess you don't have a good system in place for knowing who has and has not completed your surveys. That's too bad."
Pros: "Friendliness of staff. Second flight was a newer plane - sweet!"
Cons: "For a long flight perhaps a little more in the snack department."
Pros: "Crew was all very nice"
Cons: "Flying is always uncomfortable"
Cons: "I liked it all"
Pros: "The boarding agents were especially helpful and friendly to my disabled wife, travelling in a wheelchair."
Pros: "Not much to like here. The new crew was pleasant"
Cons: "Old crew was surly. Plane had much problems and finally replaced. Left 5 hrs late. Delta claims it doesn't have to compensate for a late flight - just a cancelled one so guess which this was The baggage fees are obscene and the gouging of the customer is immoral. No wonder people hate the airlines."
Cons: "Excellent service excellent pilot"
Pros: "Overall, the flight was very smooth and I thought the crew did a great job."
Cons: "I know this is a federal regulation, but I have to mention it as it is part of the boarding process. For the life of me, I can't understand why it is necessary to go through security again after re-entering the country. Understandable that I have to go through customs, but going through security again is ridiculous."
Pros: "Flights were both on time and boarded quickly. Crew was wonderful!"
Pros: "Free in flight entertainment"
Cons: "One of my bags went to Santa Fe"
Pros: "Early arrival. And service"

Pros: "Everything was smooth from start to finish, and the flight landed 10 min. early! Can't ask for more!"
Cons: "I've only experienced delayed flights with Delta ... and this was no exception. It wasn't weather-related, nor a late flight delivering a plane - just no ground crew to service the plane between flights."

Pros: "Minimal amount of announcements"

Cons: "When I spoke to the United person last week to confirm baggage and carry on requirements. He said I could take a carry on when I turned up to the gates I was charged another fee for my carry on bag. What is baffling is that when I arrived at Denver people were getting complementary check in baggage. I’m so dissatisfied with the booking and the amount it has now cost me ruining any savings I’d had for sanfrancisco"

Cons: "Window seat and a beverage"
Pros: "The crew was great, the prices fantastic and everything whet extremely well. We even arrived in Denver early. The flight crew did a great job of keeping turbulence down despite some conditions that were less than easy to navigate. For a no frills flight, this was fine."
Cons: "I miss the frills although they have them available all at a cost during and before the flight. If you need all the frills I would probably go to a more comfortable venue. If you bring your drink and snack and don't mind not choosing your seat, etc., this will work just fine."
Pros: "Is good"

Pros: "The first"
Cons: "This flight was canceled at the last minute and all passengers were told they needed to find another flight because the airline didn’t have any to rebook them on. Passengers had to pay out of pocket for new flights. Frontier said they would reimburse but I haven’t seen anything yet."
Pros: "Not applicable."
Cons: "Due to mechanical error, the flight was delayed, we missed our connecting flights, and customer service was rude. With all the added fees, my total flight round trip came out to $502.90, so the options given to me as partial refunds did NOT make sense ($180 if I refunded my entire return flight, which is way less than half my overall cost, or per customer service at my connecting location, “you’d be lucky if you got $80”, which is way less than a quarter of the overall cost). My connection was at Denver and my final destination was Seattle. My options were to fly to Portland, OR and figure out the rest on my own, at my cost. Or book the next flight to Seattle, which was 24 hours later. I got a voucher for up to $150 for hotel, but absolutely no assistance finding and booking a hotel, especially since they were sold out (I was looking for hotels just past midnight) or cost over twice the voucher. Am NOT flying Frontier again and I have shared my experience with friends, family, and co-workers and have strongly advised against this airline."

Pros: "Loved the pilots humor!!"
Pros: "Wish they had free snacks."
Pros: "Sort of cheap"
Cons: "Cheap at every level. Makes you feel unsafe. Are they cutting on cheap pilots too?"
Cons: "Customers service"
Cons: "I did not know you all do not provide complimentary beverages and snacks. I did not know I had to purchase a seat to sit in for check in and only one carry-on was allowed."
Pros: "Getting off the plane."
Cons: "Everything else."
Pros: "someone stole an item from my suitcase"
Pros: "There is noting positive for me to say"
