From Atlanta to Savannah - flight connection was way to short (we weren't even late landing ) and flight was already boarding when we landed - we were told we were the last on board and so we had to gate check our bags. Once we got on the plane, there were at least seven open bag spots so that was unnecessary delay. There should be better communication between the gate agent and the crew.

From Atlanta to Savannah - flight connection was way to short (we weren't even late landing ) and flight was already boarding when we landed - we were told we were the last on board and so we had to gate check our bags. Once we got on the plane, there were at least seven open bag spots so that was unnecessary delay. There should be better communication between the gate agent and the crew.

Crew was excellent. Comfort seats not as nice as other kinds of planes.

Not a "Delta" issue, but a JFK issue: We booked a connecting flight with 3 1/2 hours between to clearn immigration and customs. Our inbound flight (BCN to JFK) was on the taxiway 45 minutes which ate into our layover time. Immigtration was insanely quick with the CBP MPC app; however, clearing TSA (again, after we were ALREADY cleared in Spain on the inbound international flight) took over 95 minutes. This left us with 10 minutes before boarding the connecting flight (JFK to SAN) to walk to the far end of Terminal 4 and try to find food. We didn't find any food that could promise to serve us in under 10 minutes so we boarded the Delta flight after coming off a plance and an 8-hour flight knowing that we wouldn't be served any food on the next 5 1/2 hour flight. I feel like Delta needs to put pressure on the JFK TSA to open more screening stations (by our count, we saw only 5 scanners open and a line of - as we said - over 90 minutes. The insult is that we WERE ALREADY SCREENED through TSA, but as you come off one flight into the USA, you have to go through the whole process again. It seems like if you have a connecting flight, there should be a way to pass through immigration and customs without needing to return through TSA.

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

There are 4 flights in consecutive gates with about the same departure time. Two flights were boarding at the same time. One was delayed or boarding would be happening at the same time. I am not sure what Delta and LAX need to do to have a better layout at the end of Terminal 2

Flight was an hour late, who knows why. It was OK, nothing outstanding.

Only not having an assigned seat was an issue. Rest was great

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

I like for how they process during check in. It was very smoothly.

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

Flight was great. Efficient boarding. Short flight. Early arrival. Friendly flight crew. The entertainment system did not work well. Could not access it until the aircraft reached 10K feet or more. Lots of glitches.

A bit rush for transit. Food and entertainment are not available

Smooth boarding process. Early departure, smooth flight, early arrival. The entertainment package has very good recent movie options. The flight crew were friendly and professional.

My flight was scheduled for about 6:05 departure. There were 11 gate changes from 4-7pm and the flight was 3 hours delayed due to operational issues. The plane taxied around the airport for about half an hour before stopping to be de-iced. It would have been nice if we were alerted of the plan to de-ice prior to the 30 minute drive around the airport. The flight attendant was friendly, which was the only redeeming thing about this flight. As a former flight attendant for United, I was extremely disappointed.

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

Had a short delay once we boarded the aircraft in Chicago, but it was fixed in no time flat then we were on our way. The pilot was able to make up the time lost and we landed 5 minute later then schedualed . Great service

Our seats were all the way in back of the plane,

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

The flight times got delayed multiple times due to weather which is understandable, but later the time got prepared 30min. Made to the flight barely but got stressed too much.

Spirit charges you to breathe in their presence. They have you pick and buy your seat in advance and then I got bumped from the seat I paid for because THEY overbooked the flight by a dozen people. they do not provide any entertainment, they do not provide even a small cup of water - you have to pay for everything. I will never fly Spirit again.

why's KAYAK involved? why'd Spirit charge me $19.72 on Apr 28 and $4.49 on May 1 ? And ironically my credit card had to be cancelled after trip due to a bogus charge, wonder if using it on the plane enabled a scammer to get it.

Worst airline ever! The guy weighing my bag had his foot on the metal plate and when I called him out on it, I got this stupid little smirk. La is a scam and so is Spirit Airlines. All the flight attendants looked like they hated our flight just as much as we did.

Very dissatisfied with spirit airlines after buying my ticket's they cancelled our flights with no reasoning.

Spirit is awful. Too expensive for what you get. Stop nickel and diming.

Good crew and safe. However, comfort and being nickeled-and-dimed are my issues. $75 each way for luggage is exhortation. The space to the next seat is so close you cannot open a laptop. The magazine rack doesn’t hold your items. Not a fan.

WiFi could have been a little more consistent - otherwise a phenomenal and positive experience. The 1000 mile giveaway was awesome!!!

Loved staff help @ kiosk, staff on airplane. Commitment to punctuality. I sat in a "blocked" row, where the middle seat had no passenger & loved it! I appreciate not having to pay for water, which I've experienced even on international flights. Only negative was how dirty the bathroom was for a 4.5 hrs flight. But I don't think flight attendants monitor this.

My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.

We were delayed three times ,and that destroyed my plans, and reservations

Very bad! No good service delayed my second connection flight

The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.

Flight was late. Missed connecting in Denver. My new flight is more than 24 hours later and I have no room, vouchers, or compensation, and might also be bumped from the one tomorrow.

Frontier is terrible. Paid for exit row, not given exit row, refused to refund fee.

2 hour delay due to late plane, wrong size plane causing overbooking, and people getting off and on the plane after boarding was completed.

We had to wait in line over an hour just to check our bags. It's a good thing we were so early to the airport. Only one clerk was working and the line was around the corner and down the hall. No good. I felt bad for her. Not sure how she kept her sanity with all the upset people. Then we get to our gate and there is no seating. Everyone was standing. Then I realize it is not a gate at all, we still have to be shuttled to our airplane. Ugh. Then we were late taking off and missed a window of opportunity before the airport runways were shut down for some reason. (not frontier's fault the runway shut down.) The seats on the airline are crammed and there is no cushion. Never had a tighter seating arrangement while flying. My 6' 4" husband was absolutely miserable the whole time with knees digging in to the seat in front of him. You think you are getting a good deal on a ticket, and then wham! I had to pay 75 dollars for our checked bags and 75 dollars for a carry on. No other airline does that!!! And also, there is a 40 pound weight limit on checked bags... Would have been cheaper flying with another airline, and I would have at least gotten a snack and drink. Was thankful for the tiny cup of water at least.

This was one of the first frontier airline flights this spring that wasn't delayed. It actually left on time. Some of the flight crew did not look happy, they didn't smile when the passengers were boarding or getting off the plane, and the passengers initiated greetings, not the staff. To me this was an odd experience to have with any flight/airline. I had a bad experience booking this flight. The price didn't solidify until late hours into the night. Ever time I purchased the ticket, I either received a denial email or an error because the price has changed, but it was never reflected on the flyfrontier or kayak websites until way after midnight on the date of travel. This caused me anxiety and irritation with the websites. Then I noticed a mishap with my name on my voucher as I went to check in, it was incorrect. When I proceeded to correct it, Frontier had no easy, let alone free, way to remedy it. I couldn't correct my name without a $75 charge, I couldn't cancel my voucher to repurchase it with the correct name without a $100 charge, because it was too close to departure. Then calling frontier was nearly impossible to remedy the situation with a human. It's already difficult to want to choose frontier because of all the upcharges, but you feel kinda trapped into doing so because it's the more affordable airline.

They canceled flight. Hard to believe there was even a plane incoming for us to get on
