Airline reviews

Pros: "Aircraft was clean and comfortable. Crew was efficient and friendly. The whole experience was excellent!"
Cons: "There was lots of entertainment available but plain old music was not an option. What if I don't want to watch a movie or TV, just listen to music!"

Cons: "Seat cushions are too thin."

Cons: "Two rows up from us, I kid threw up all over the center aisle as we were pulling away from the gate. We returned to the gate to allow a cleaning crew to board and clean. However, the cleaning job was rushed and left remnants of the throw up behind which smelled the whole 2.5 hour flight. It really felt unsanitary and unsafe being that it’s unknown what caused the child to get sick. It very well could have been a stomach virus and could have infected the people in rows around the incident due to the mediocre cleaning job. I understand that it’s important to keep flights on-time, especially for connecting flights, but the safety of the passengers and their health should ALWAYS be the #1 priority."

Pros: "Comfortable seats with nice details; power ports; drinks and snacks."
Cons: "Boarding in Seattle was ridiculous. Security took a massive amount of time, and we barely arrived in time for th flight despite arriving hours early. The attendants at the gate were a bit rude and begrudgingly accommodating."

Pros: "Early flight, and short. I think I slept through it. Woke up sore, but eh I'm not surprised by that. I'm a giant and no one woke me up for anything so I was satisfied."

Pros: "The crew and captain were amazing and very apologetic!"
Cons: "I paid an extra $300 for preferred seating because I wanted the extra legroom to sleep. I'm over 6 feet so coach is very uncomfortable. My girlfriend and I got in our seats and 10 minutes later, a crew member walked back and asked us to get off the flight. We got off the flight and were met by police officer. Low and behold, the woman sitting next to us said that she believed we were intoxicated and feared for her safety. I am a police officer and my girlfriend is a nanny/preschool teacher. Not very threatening. The officer on the ground looked us over and asked us a few questions and determined we were not intoxicated and we were no threat to the other passengers. The airline asked us to get back on the flight and we would be sitting in coach because the woman adult children were now sitting in our seats. I told them to book us on another flight with the same seats that I PAID for or put us back in OUR seats on that same flight we just got kicked off of. We were escorted back onto the flight and the crew asked the woman's children to go back to their seats so we could have our seats back. They then asked us not to speak to the woman sitting next to us (which we never did to begin with!!!) and then told us we could have free food and drinks. The whole experience was insanely embarrassed and I can't believe that woman sitting next to us can get away with what she did. I am absolutely livid that they would ask us to get off the flight and then give our seats to the woman's ADULT children without vetting the situation and making the easy determination that we were NOT intoxicated. So embarrassing!!"

Pros: "Glad I discovered Alaska Airlines!"

Pros: "It got cancelled due to 3 inch of snow. And I missed work in Denver because of it. Very inconvenient"

Pros: "Offering price"

Cons: "Cramped seating"

Pros: "good"

Cons: "Nicest people ever."

Pros: "My favorite airline to travel from Denver to Puerto Rico, round trip, and in Atlanta I will make the stopover, I also feel so safer to travel with my cat ... they are the best airline in everything"

Cons: "Plane smelled like urine"

Pros: "Delta is doing a great job keeping everything calm and clean during this pandemic!"

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""

Pros: "Entertainment"
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."

Cons: "The Wi-Fi cut out a bit"

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: "Every aspect of this trip with Delta was super! We were on time, a bit early even. The flight was smooth and comfortable."
Cons: "I would prefer fresh fruit or vegetables as a snack."

Pros: "Free drinks and snacks - great entertainment system (please read this Frontier)!"
Cons: "Boarding process was agonizingly slow and ineffective"

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: "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: "Great to have in flight TV"

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: "The plane, crew was clean, newer and had TV's in the backrests. Remember to bring headphones! Seats are tight, but the crew was friendly and may the flight experience positive."

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"

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: "nothing"
Cons: "not enough leg room and space. The business class should be at the minimum for economy. My standard carry on luggage did not fit the over head compartment."

Pros: "Nothing"
Cons: "Not allowed unleashed dogs to take my seat or be in my flight"

Cons: "The plane had a mechanical issue that they needed to address (due to the fact that they prior crew did not address it) and we sat in the gate for 2 hours waiting. No worries water was offered by crew and the flight had no food."

Cons: "Flight got delayed. We paid for assigned seating for our almost 85 yo mom. And the change in flight no one asked for to get seated in the front of plane. Instead she was seated all the way in the back. It was physically exhausting for her."

Pros: "Crew was great"
Cons: "Absolutely no accommodation for seat assignments and the lady at the gate was so rude for even just asking to sit next to my fiancé even though there were tons of single people on the flight."

Pros: "The flight itself was fine."
Cons: "The gate change was not announced on my phone app (changed from E7 to D49). I hate leaving out of Terminal E at MIA. There is no point to having TSA Pre-Check if you have to stand in line with people who don't have it. I have to remove my liquids and laptop. It's such a shabby, run-down terminal."

Pros: "Crew was nice"
Cons: "Not enough leg room. They did a gate change and I almost missed the flight because nothing was announced and when I looked at my phone app it had the previous gate."

Pros: "Overhead bins were newly done with plenty of space since carryon can be placed vertical on side. Decide holder built into the seat was very nice."

Pros: "Nice staff"

Cons: "I hate Americans boarding process"

Cons: "3+ hour flight with no TV/ entertainment"

Pros: "Seats were too tight and too close together."

Pros: "Movie and tv selection was good. Boarding was a cinch, we took off exactly on time, seats were comfortable, too."
Cons: "Airline misplaced my boyfriend's checked back with our duty free Portuguese wine in it. It still hasn't been delivered to him the next day. They had three hours to get the bag on the flight."

Pros: "Nothing in particular"
Cons: "Outlet did not work"

Cons: "Flight crew was late and didn’t try and make things move faster to make up time. Kept saying they wanted to go Puerto Rico and that’s where they should have been going."

Pros: "More improved than the last trip I took with AA to Denver. Efficient boarding."

Pros: "Everything"

Pros: "The plane was sleek and clean. I had a good amount of room even in coach!"

Pros: "Nothing. AA is the worst airline. Period."
Cons: "Rude flight attendants, delayed flight (as always), just AWFUL."

Cons: "The flight was 3 hrs late, of which 1.5 before boarding, and almost 1.5 stuck in the plane."

Pros: "Flight not entirely sold out. So they let my 14 month grandson have an empty seat between my daughter and I. That was a great gift since he doesn't sleep and is jumping and crawling all over the place. And I'm sure the other passengers were breathing sighs of relief!! Also super smooth landing and nice flight attendants."
Cons: "Flying with an active 14 month old toddler boy and of his "stuff" is nothing less than anxiety provoking. Not much the airline can do.."

Pros: "Crew"
Cons: "Had to board three times, two different planes. I understand mechanical problems, but 3 hours later, and on another plane, the captain starts making stuff up, saying that the only reason we hadn't moved in the last hour was because people were using the bathroom, then something about having to deplane because the plane couldn't back up with us on it because of some sensor? And then, surprise ! All of the sudden they noticed there was an issue with his and some of the crews' hours and we had to wait till they could locate more crew. But they gave us each a 1/3 glass of water and later a $12 food voucher which didn't even cover a meal and beverage. Whoop-de-do. 7 hours later we finally boarded for the third and last time. The crew on the other hand stayed professional and friendly."

Cons: "Seats too small and the gentleman next to me was a big guy so crowded over into my seat some."

Pros: "Very friendly staff"

Pros: "The plane was new on the interior and comfortable."

Cons: "The customer service from AA representitives in the airport was completely unnacceptable and the absolute worst service I have recieved in an airport to date! One incident during this trip was as follows: When arriving in Charlotte and running to catch my connecting flight, I arrived as the lady at the desk was closing the door, she looked at me and rolled her eyes. When I went up to the desk along with the other passengers arriving from the same flight as me the AA representative said "Hurry up , I want to go home!! At a point I'm just going to cut you off and that will be it!" She was of no help to me in anyway amd was forced tonstay the night in charlotte ; Normally this would not have been such a big deal, However I am on emergency leave from the Navy rushing home because I have a very serious family emergency, that representitive was very lucky I held my temper! From now on thanks to the poor unproffessional customer service I received I will no longer be flying American Airlines!"

Pros: "Nothing"
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.

Pros: "Nothing. I don't know how frontier is still operating. They are a terrible airline. When I went to the airport to check in, 5$3 man at the counter said he was off shift and just walked away with no one to release him. It took us 15 minutes to get checked it. There are also NO barf bags anywhere to be found on flight. It was awful. Our flight arrived AN HOUR early and it was extremely turbulent and I barfed so much. It was disgusting. & will never take Frontier again."
Cons: "Everything. I hate Frontier. They are the dumpsters of airlines. 8 would rather pay $100-500 extra to fly ANY OTHER airline."

Pros: "I love how quick the flight was!! Great"
Cons: "The cost for a checked bag is expensive. Suggest a flat fee"

Pros: "Personnel were great"
Cons: "Luggage took over an hour"

Cons: "50 minutes late with no warning"

Pros: "quick flight with great service"

Pros: "the person sitting next to me was nice. the crew was great."
Cons: "getting charged $40 to carry on a small fly rod. i think that is so crazy, since it is no where near the size of a bag. also, when we arrived, they told us the wrong baggage claim repeatedly, so we waited an hour until ONE OF THE PASSENGERS figured out they put the bags on another claim. get it together, Frontier. they are literally the worst airline. WORST."

Cons: "40 minutes and still no bags"

Cons: "The same 2 screaming babies entire flights. Attendants allowed with no assistance."

Pros: "Prices are very reasonable"
Cons: "Frontier is struggling at the Denver airport. During my flight out of Denver, the "Bag Drop" line took a very long time and they only had 2 people working. On my flight back into Denver we arrived early but had to sit on the tarmac for almost an hour before we could get off the plane and then had to wait another half and hour for our luggage. It was very frustrating and I ended up leaving the airport at 12am instead of 10:30pm. Normally I have not had this type of experience with Frontier but this time around if was very disappointing."

Cons: "."

Cons: "There were several delays."

Cons: "A bit more room on plane"

Pros: "Simple, straightforward"
Cons: "I miss the old Frontier. They are doing a drastically better job than Spirit, but I hate that I'm even grouping the two together. The constant upselling is chintzy. Having to pay $80 to bring a carryon is absurd. I get that it can be hard to make the finances work sometimes. But this isn't fun."

Cons: "Everything about Frontier tells me that they'd prefer to stick me in their size box and charge me extra."

Pros: "Very little"
Cons: "Poor arrival jetway control. Terrible luggage work."

Pros: "Planes were in good condition and the seats were comfortable."
Cons: "First, the flight was late which cut down my 90 min layover by 30 minutes. I understand that weather can be a HUGE variable when flying-however, when I asked a flight attendant if they had connecting flight information while we were waiting on the tarmac for over 30 minutes to get a gate when we landed- she responded with "I'm on the same flight as you, I don't know"....really?! That is NOT customer service and I asked very politely and was responded to rudely. The response of the people all around me was confirmation that it wasn't just in my head. Completely uncalled for. It would have been simple to say, "Sorry, I haven't received any information but let me check and I'll get back to you." Another 30 minutes later we are finally able to get off the plane. 0 min Layover. Thankfully they held the connecting flight leaving for charlotte so I wasn't stuck in Denver."

Pros: "I like that Frontier offers a flight direct from Bozeman to Denver."
Cons: "I did not like all the sneaky additional charges after purchasing my ticket. I should not have to pay to bring one checked bag or one carry on. I did not like that you have to pay for any snacks/drinks besides water. I didn't like that frontier tried to charge me for picking my seat when checking in online 24houra before my flight."

Pros: "Plane eventually arrived at destination."

Cons: "I didn't like being charged $40 for a carry on bag. I didn't like the uncomfortable seating for a red eye flight. Most people sleep on those and need some comfort. I didn't like having to pay for drinks and snacks. Yes frontier is a little cheaper but after figuring in what I spend on carry on bags and drinks and snacks, I should of paid for a different airline with more amenities and comfort."

Pros: "Entirely Average."
Cons: "Both of my flights were very late."

Cons: "5 hr delay with no explanation."

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: "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."
