Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

4.0 OkayDavwinder Singh, Jun 2024SEA - ATL
Read more about Delta reviews

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Flight was delayed in the gate by 5 hours and ultimately cancelled- rebooking service by United agents was terrible

The plane was dirty and the in seat air wasn't blowing as planes usually do.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

Terrible. I didn’t fly and I had an important meeting the next day.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

Nice aircraft. Plane was PACKED full and distance between seats was tight. Had it been more than a two hour flight it would not have been tolerable. I had much more knee space on the JetBlue flight I went out on.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

Literally the worst experience ever and I had my service dog with me. Flight was supposed to leave at 1:51 PM but the plane arrived late. They boarded us around 3 PM and kept us on the plane for an hour saying that due to weather conditions in Miami, we could not takeoff yet. After waiting for an hour, they deplaned. And then they will not give us our bags back that we could just leave and schedule for another flight. Every hour they kept updating saying we have to wait another hour without any explanation as to what was going on. Eventually, I went to customer service to change my ticket, but by the time I made it to the front of the line, they started boarding my flight again. And then when we got onto the flight, they said there were two flight attendants That were past their shift. They kept us on the plane for about another 40 minutes until they told us they had no other flight attendance and had to deplane again. Then I gave us hotel vouchers and told us we would be on a flight at 6 AM the next day. At this point it is about 9 PM. I get to the hotel with my dog, who hasn’t been able to go potty for about eight hours. When I arrived at the hotel, I got a text alert saying my flight has been canceled at 6 AM and they moved past to 5 AM, however the hotel shuttle doesn’t leave early enough to make it to the airport for 5 AM flight. So me and some other passengers got a cab after about three hours of sleep to get back to the airport. This was the worst experience ever.

Their computers were down upon arrival to the airport. They were unable to figure out how to board us. We were delayed over an hour and a half.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

The flight was on time and nice as always for me with spirit but the cabin crew were not good. They left the lights on on a red eye for the entire flight.

Arrived 3 hours early and never made it past baggage drop

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

Terrible as usual!!!! Very unprofessional and rude flight attendants! You get what you pay for! HORRIBLE

The text told me it was changed to Terminal E and Gate D5. But with no one on site to ask questions there was confusion on where to go as all the gates were E's. Then we took the skyline to the D area. We left to get something to eat. No announcement was made but my daughter happened to asked and they told her our gate was moved to D12. I will not fly Spirit again.

Unnecessary announcements through out flight. WiFi on plane is terrible and overpriced

Cancelled my flight last minute and had to end up driving to Texas from Atlanta last minute. I’m going to miss another day of work, drive back to Atlanta , in my own car and spirit doesn’t want to refund the money. First time I tried flying anyone else but delta and I get ripped off . And I had. To pay for seats for a flight that didn’t happen. Usually you could say you get what you pay for but in this case, didn’t get anything and paid for everything never flying spirit again, or even attempting it or thinking about it.

Flight from Tampa to Houston was canceled. SPIRIT rebooked me and they double booked my seat. Conclusion I COULD NOT TRAVEL TO HOUSTON. I MISSED MY GRANDDAUGHTER BIRTHDAY. I would not recommend this company. I will file a complaint. I will never consider SPIRIT as an airline . It’s a faker.
