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."
Pros: "Flight was good and crew were good. Nothing very outstanding but by no means a terrible flight."
Cons: "The in flight screens weren't working well."
Pros: "Everything was on time and ran smoothly. The seats have more room than most airlines. They were generous with drinks and snacks."
Pros: "The airplane seats and entertainment were 150% bettter than American"
Cons: "The check in area felt cramped, understaffed and like a 4th rate airline"
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."
Pros: "Pilot was super nice and informative when the flight was delayed."
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: "I usually have had great experiences with Delta. The meal selection was limited. By the time they made it up to my seat they had run out of what we wanted. Also, the entertainment system at my seat and my husbands wasn’t working well. One of the bathrooms had a cabinets Tvst oliiiooooiiooooioiooiiiooiio"
Pros: "Ok time"
Cons: "Frontier charges for absolutely everything, and the chairs are very uncomfortable, they have hardly any padding and don’t recline"
Pros: "Everything else was fine."
Cons: "The flight was delayed 30 mins prior to boarding for 6 hours. They were missing a part that needed to be ordered. What I don't understand is why they couldn't have emailed everyone to notify us so we weren't stuck in the airport for 6 hours."
Cons: "All Kiosk check in machines were out of service and there was only two attendants at the desk checking people in. The check in process took very long ."
Pros: "Price of tickets if I could have used them"
Cons: "The flight was 4 hours late which caused us to miss our. Connecting flight in Denver and we were told the other flights were overbooked for Frontier were overbooked and we could not get out til Wednesday or Thursday and our vacation was over Friday and then I have been trying to get a refund of just my tickets which I was promised by the check in people and a number they gave me and they assured me I would get a refund in 10 days and I haven't gotten it yet!,"
Pros: "Fast everything"
Cons: "Small seat space/isle room I am 6'4 and had trouble keeping circulation in my legs. And the last second $45 fee means never again for me!"
Pros: "The 1st 3 rows recline and have a little extra space which is nice for a toddler in a carseat! Flight attendants were very nice."
Cons: "Most disorganized bag check i have ever seen/experienced! We were in line for over an hour and a half just to get moved to different lines 4 times, due to them being so overwhelmed at 6am! We were 2 people away from checking in our luggage when they told our whole line to get in the back of another completely full line so they could check in just Chicago flights. We had waited for over 30 minutes to get up to the spot we were at. Then the line that they physically took us to stand in and waited for another 15 minutes in they shut down and made a "help" line. We were then escorted to the back of another out the door end of the line to wait another 30 minutes just to be moved again to finally a shorter line because they noticed that most of us moved around multiple times were going to now miss our flights. We were then rushed to the security (thank God TIA had their act together and handled a ton of people in a very short amount of time) and were told to hurry to our gate. Frontier staff "double checked" that our planes gate was still the gate on our ticket...jusy to find they had moved us to another gate. Through this whole issue, employees made the comments that we should arrive 2 hours prior to our flight when we were rushing through and explaining we kept getting put/moved into the back of different long lines to check in our bags and get to our gate. We were there 2.5 hours early!!! Thank goodness the person that was supposed to be working the gate desk for boarding didn't show up to work (according to the gentleman that showed up with a radio calling for any help from available staff 10 minutes after we were supposed to board) otherwise we might have not made our flight! Flight was supposed to board at 07:35 am, we did not board until 08:10 am and we were supposed to leave at 08:10 am. Our plane finally took off at 09:50 am...after multiple times having our whole plane's occupants were counted multiple times because the gal who took our tickets got a different number than the flight attendants, and all of our tickets checked multiple times (I do appreciate the safety checks but this was ridiculous with the flight attendants finally stating that their numbers were correct and that policy was to go by their numbers and not the other gals numbers!) The flight attendants were even completely annoyed! Needless to say...i will not be spending any more time or money with frontier airways!!!"
Pros: "We appreciated the cheap airline ticket prices."
Cons: "We were outraged by having to pay $45 for each piece of luggage, including carry ons! After these hidden fees, our tickets would have been cheaper for a well established and popular airline."
Pros: "The flight left on time and I arrived at my destination at the correct time."
Cons: "The Frontier rep at the front charged me $45 for a carry on, when I had just flown Frontier and they did not charge me for my carry on. An additional $45 I was not planning on spending."
Pros: "THE PRICE, free glass of water"
Cons: "After waiting for 4 flights, listening to guest comments and taking notice of other flights, it was obvious that arrivals and departures are late on a regular bases and the crews, 2 of which were late, causing nearly 200 people to be delayed, inconvenienced and some missing their connections, show no concern. After a mechanical issue was fixed, the entire crew gathered for a gab fest that added 25 minutes to our departure, no explanation, no apologies. one flight was delayed over 4 Hrs. The phrease repeated was " Never Again" and I concur."
Cons: "Seats don't recline. No kind of service at all."
Pros: "Got thrown in an emergency exit row fo free (I'm 6'3") so that was nice...crew was all friendly, pilot got us in early."
Cons: "Checking kiosk was broken in PHX....but considering that got me an exit row with extra space that seems like a moot point."
Pros: "Price"
Cons: "I was sick all morning. Got there at 1130 for a 1208 flight. No sympathy. Has to spend money for another one way ticket."
Pros: "Friendly helpful and nice people at check in"
Cons: "Plane was over an hour late which made me miss an event at my destination. The seat I was sitting in smelled as though someone vomited."
Pros: "Seat was comfortable"
Cons: "It cost more for a carry on bag than a checked bag."
Cons: "I know Spirit offers low fares and in return you pay for everything else, seats, carry-on bags, boarding passes (if you don't print yourself), drinks, etc. In knowing this I did my due diligence before this flight to make sure I wasn't going to be charged for things like the size of my purse (I measured it), etc. Upon check in for this flight, I was informed that I owed $30 because my checked bag was 43 lbs and Spirit has a weight limit of 40 lbs. The other customers in line were just as shocked. To me, the standard is 50 lbs. With that being said, in my research on Spirits website this was not clear. I think this sort of fee should be much more prominent. I am a "prepar-er" if you will and for me to not know this charge was coming tells me Spirit most likely makes a lot of money off of passengers regularly having to pay this unexpected fee at check in. The ticketing agent told me it happens daily after I asked him. This feels a bit like a scam, in my opinion. Spirit will say "It's on our website" and I'm sure it is but again, I don't feel like this charge for a weight that's standard is 50 lbs is clearly called out to passengers. I'm fine with no frills, I'm not fine with unexpected charges that I feel are under the radar until the 11th hour when you have no choice but to pay or repack. Uncool, spirit."
Cons: "It is impossible to pay for bags at booking at the lower rate. Couldn't get on line payments to work. But they kept trying to get money- for seats, for better boarding, for insurance- it never ended!!! Had to call. They wanted to charge me $100 for 2 bags since they helped me. Supervisor did nothing. Told me I should have booked directly with Spirit to pay for bags at lowest rate. So why do they offer themselves to search engines like Kayak? It all amounts to hidden costs and terrible service. Flight was delayed understandably because of weather in Denver. BUT, since the only way to make our connection was not to get our luggage, they refused to get our luggage on another flight on our connecting airline. Said we'd have to figure it out with Fed Ex. No solutions or help offered. I will never fly Spirit again."
Pros: "Safe travel & few problems with boarding."
Cons: "Almost impossible to understand the flight attendants over the speaker. All the passengers looked at each other & asked what was said. Any safety message would have been a complete loss. Speak more slowly, and check the amplification of the speaker. Aisle seat DOES NOT have sufficient space for the dimensions given for the one personal item. So I had to locate another space to stow my item, inconveniencing another traveler."
Pros: "First we are flying due to a death in the family. We pay $60 per ticket. Next we get to the airport to check in to find out we had to pay for our seats even after we pay for our seats already. Then we find out that our small carry in bags are another fee. $55 dollars for each bag. So needless to say we had questions so we decided to check in at the counter in person. Oh she answers our questions the. Proceeded to tell us that because we checked in at the counter (because of questions and hidden fees) there was another fee of $10 person passenger. So we get onto the plane. To find out that if you want anything including water, it's at lease another $3.00. For water? Are you kidding? Then we get comfortable in a plane that is sized for a small child. The hear not once, not twice, but three times about a credit card. I am appalled to be bugged three times about a personal finance. Jeez. I didn't pay that much money to be sold on a credit card. I would expect this from a time share. And finally when the plan landed it actually rattled. Sounded like the wings were going to fall down off. So needless to say you have lost our business. We will never fly with Spirit again and neither will my family members."
Cons: "Wasn't asked if I wanted snacks or a drink. Drove by the first 4 rows without a word."
Pros: "Crew made jokes, trying to be nice because we were already delayed"
Cons: "$55 carry on bag fee, expensive drinks, delayed flight."
