Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

For my birthday trip this was my second time ever flying, this trip was the best.

after landing, we stay 2 hours on the taxi way before reaching the gate The airline and the crew were good though

No trays in our seats, we sat in first row, purchased a business class fare. Had to hold our drinks and snack in our hands. No plugs for our cell phones. Had to pay for it a drink cocktail each. Seats so uncomfortable.

Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Sat on tarmac for 2 hours and then missed my connecting flight

First time traveling on Southwest since bag fees were implemented. Usual good service. Just more expensive now.

Everything was on time. I was disappointed by the front section female, African American flight attendant. I did not see her name tag or would have identified by name not race. As passengers moved to the bathroom early in flight, she would say with a disdainful tone “I have to say the seat belt light is on” then go back to her book. Better trained flight attendants say something like be careful the seat belt light is on.

Cluster mess boarding. Can't wait for SWA reserved seating. Internet didn't seem to work on the plane.

Flights delayed by 4-6 hours. Boarding was a mess and unclear. Bags were not at arrival airport and had never even been put on the plane. No idea when I’ll get them. Don’t fly into Denver!

Delta is my preferred airline. I've traveled with them for years. On time in most cases, good communication, easy to use app. Most planes are pretty nice. I was on a CRJ 700/900 however, which was pretty badly aged inside and needed a refresh. No infotainment, unreliable wifi, best to download before boarding or bring a book. Food choices are really just snacks on this flight, nice variety but about what you'd expect. Great staff and prompt in departure and early arrival too. Overall quite satisfied.

A little bumpy ride . No food was being provided due the the turbulence. That was ok it was a short flight to my standards.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Broken jer bridge. Poor communication about it. Lost 2 of 4 luggage pieces

Coach seating is debilitating, neither my husband or I can walk the following day

Extremely dosappoontined and frustrated. Refused entry to lounge in Detroit despite having Delta AMEX Reserve linked in MyDelta phone app as revommended and also having proof of account. No pillows were available for overnight flight to AMS and breakfast was not served in Delta Comfort.

I liked the screens in the seat headrest with movies to watch. I didn’t like being forced to check my carryon bag and being told there wasn’t room for my bag - when there were 5 bins sitting empty on takeoff. I didn’t like the “I don’t give a fig” attitude of the flight attendants and the delta gate attendants when I asked why they decided to put me out. They gave me a 1800 number to call but I can’t get a live person on the phone. Customer service is non existent. My business must not be that important to them.

The airplanes were so old and out-dated it was terrifying to fly on them.

Like all flights, the seats are small and not comfortable. My first leg was delayed but delta rebooked 2nd leg so my arrival at final destination was only 2 hours later than original flight.

Love delta but the delays and long waits for updates was just too much this time.

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

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

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

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.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

American Airlines initially postponed the flight. Then they cancelled it an rescheduled us on a flight that would take over 24 hours with multiple stops. They then changed this flight to a reasonable alternative the next day which they later cancelled and replaced with a flight that would take off with an additional 16 hour delay. They blamed weather but I noticed (at 4am) that Delta had direct flights from Charlotte to Detroit. I went on line. Booked it and was in Detroit buy 9am. The interesting thing is they did a similar thing to a family member just 2 days earlier. I don't think I will fly American unless I have to.

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.

Not very good because of an almost 3 hour delay for an hour long flight.

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.

I paid for streaming wifi and the connection was poor.

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.

Bad experience. Unhappy with the changing of flight times and one particular flight attendant (Bartholomew) on our flight from Orlando to Detroit. Traveling with a large family of 7, including our 18 month old, can be arduous but when the airline changes your flight time from landing at 9:30 pm to landing after midnight, this becomes much more difficult. When our 18 month old was predictably over tired and fussy, my wife and I tried to move to an open row so we can console her more effectively. The flight attendent rebuked us and said we could not sit in an exit row. We were not planning on sitting there for more than a few minutes but just to have space to console our screaming 18 month old. Spirit did not allow for a family friendly trip. Likely will be choosing a different airline next time.

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.

Pl meed tp make proper accom for all pets and owners by placing them on a section to accommodate human animal allergies and give up a few seats YWS ACCOMMODATIONS SHOULD BE MADEBY THE AIRLINES and not pushed off to another paying customer that has to sit in fear or by being touched by someone elses animal.

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

Your employees need to learn how to talk to people as creations of Yah. We are not their children nor are we lower than them.
