Airline reviews
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Pros: "The staff at Delta are always friendly and helpful and they were able to squeeze me onto a very full flight."
Cons: "Communicating take off time!!! It changed multiple times by one three hours and ended up flying the next day!"
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: "Not really an experienced flyer. Overall the flight seemed good. No issues with airline or airport. Just don’t understand self-important people that feel compelled to push the overhead storage limits with their bags."
Pros: "Love the fact that the head rests move to support your head better."
Cons: "No meal option and my video screen volume did not work"
Pros: "Not comfortable a little but scary on the flight to Detroit. Way better coming back to Denver"
Cons: "First delay notification: 1 hour 20 minutes 1 hour later, Second delay notification: 3 hours 15 minutes 2 hours later: Third delay notification: 3 hour 50 minutes Fourth delay notification: 4 hours 25 minutes Fifth delay notification: 4 hour 32 minutes No explanation for reason. Last time flying Delta."
Pros: "The crew on the airplane was great. We had 2.5 hours turbulences but the crew started to give out drinks as soon they got the ok from the pilot"
Cons: "We went in LGA to the Baggage drop off and the employee there was super rude. On the flight to New York with Delta we had to check our carry ons at the gate because it wasn't enough room for bags in the airplane.so we asked when we checked our one suitcase if we can/should check our carry ons to avoid having to do it at the gate. The delta employee told me sure no problem. He checks in my one suitcase I purchased gives me the tracking paper and says ok have a good flight. I asked him so what is with our carry ons and he told us that that would cost 25$ and we can't check those in at the drop off?!?We ended up taking the carry ons with to the gate and then off course there wasn't enough room on the airplane that we had to check it in. And surprise it was free?? We had never issues with Lufthansa, icelandair etc. with checking our bags at drop off to not needing to carry it around and than still end up to check it at the airplane. Every airline has been more than happy that we volunteer to check our bags that they don't have the trouble at the gate."
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: "The flight was cheap!"
Cons: "The flight was cheap... Meaning you even have to pay for a drink. They didn't even offer water and in the winter it is incredibly dry. I also almost paid 50 dollars for a carry-on that I was entitled to. Luckily I called to confirm that I've personal item is included."
Pros: "simplicity."
Cons: "help but i had to pay to change my flight during Harvey. I paid double because of it. second time they did it free of charge, it should have been free of charge my ticket was 157, it bacame 300+. seats dont recline. tough for your back."
Pros: "Everyone was so nice, from the sweet girl who checked our bags in Houston to all the flight attendants on the plane."
Cons: "The girl in Houston could've used some help"
Pros: "All good. 1 stars for food and entertainment cuz there was none, at least food only for purchase. Understandable though."
Pros: "Everything was on time"
Cons: "The landing was miserable, getting off the plane took about 35 minutes."
Pros: "I loved that the plane was new (at least it looked like it) and super clean and that the flight was ON TIME!"
Cons: "Don't bother paying extra for a seat. The crew does not enforce that everyone is sitting where they are supposed to. I paid extra for a seat, and someone was sitting there and refused to get up. I didn't want to make a scene, as I don't want to be on the news for trouble on an aircraft, but I would appreciate it if the crew would make sure people are sitting where they are supposed to if seating costs money."
Pros: "Efficient flight and crew"
Cons: "Extra 45.00 charged for laptop bag brought with me. The only piece of luggage or carry on. Rediculas"
Pros: "no free drinks or snacks, everything is an extra charge. no hospitality. the workers were helpful though but didn't smile much"
Pros: "Staff was very friendly and efficient."
Cons: "Food options were awful, especially for what they charge for food."
Pros: "Not trying to be hurtful, but not much. The people sitting next to me were nice. The temperature was fine. Nice takeoff, flight, and landing. The seating in the terminal was comfortable."
Cons: "The boarding was completely disorganized. The crew unprofessional. I overheard one crew member say to another "What is it with these Denver weirdos?". Then they complained about work and passengers the rest of the trip. I was in the front row and they must've assumed I couldn't hear them. I could. I know you're trying to reduce fares and making it an more a la cart experience, but $2.99 for a can of soda? Having to avoid the pile of ice that was dumped by the flight crew into the bathroom sink when i washed my hands wasn't very pleasant. The chairs are still incredibly uncomfortable, even in my "stretch" seating assignment ($35 poorly spent on my part). This trip made me rethink the cost benefit of taking Frontier. Flying United or American may be worth the extra money. And that's coming from someone on a tight budget. I used to enjoy flying Frontier and love taking a plane in general. I surely didn't this time."
Cons: "the seats are very uncomfortable. and there are no wifi or entertaining on the plane."
Pros: "The crew was funny. We did airplane yoga and they made jokes."
Cons: "The flight was delayed by an hour. There was poor communication to the passengers and on the website. My family members thought my flight was on time for a while before the website updated. While on the jetway awaiting our departure, frustrated passengers started getting up and walking around. The crew began reprimanding us like children with a very undesireable tone. I get the customers were out of line but there had to be a better approach."
Cons: "Not much leg room. They don't serve food. They have outrages bag fees. I don't recommend this airline to anyone."
Pros: "Flight was smooth and relaxing"
Cons: "The delay but it wasn't to long of a delay"
Pros: "ABSOLUTELY NOTHING!!!"
Cons: "Everything. Glee spirit one other time and completely regret it. Haven't flown with them in 4 years. I remember why now. Flight was originally cheaper but by the time you pay all of there fees to get on the plane you're not saving at all. And once on the plane everything costs a fortune so now you've spent even more. They are never on time in my experiences and don't feel the need to give the paying customers updates. After several hours of delays you get the pleasure of being absolutely crammed in their crappy aircraft. NEVER AGAIN!"
Pros: "Nothing"
Cons: "I arrived at the terminal three hours early, connecting from a non-Spirit flight from Central America. Spirit employees wouldn't check me in, saying they were too busy and I need to wait, but no worry, there's plenty of time. Asked again later and was told to check in online. Checked in online and was told (after the many upsell screens) that I couldn't print a boarding pass and needed to go to a Spirit counter. Went back to the Spirit gate and they said I hadn't checked in so they gave away my seat, and they didn't have another flight until tomorrow. Did I want it? Nope. Bought tickets on a real airline. Will never, ever travel with Spirit again."
Pros: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"
Cons: "They shut the doors early I miss my flight they refused to give me a refund waste of money as usual"
Pros: "I liked how peaceful it was. No crying or screaming children, no loud adults, no loud games. The flight crew were very polite, courteous, and showed compassion for the passengers. The air pressure wasn't to much. It was just right."
Cons: "No reclining seats."
Cons: "The seats are cramped and on the way back, they canceled all flights back to Houston, causing us to pay an extra $600 in order to get home to work on Monday."
