If your boarding Military, it should be with ore board, and with my spouse, so rude and stupid to not let us board together and before a group. All the other airlines clearly understand Military courtesy, this is why I Rarely fly SWA and Always fly Alaska

If your boarding Military, it should be with ore board, and with my spouse, so rude and stupid to not let us board together and before a group. All the other airlines clearly understand Military courtesy, this is why I Rarely fly SWA and Always fly Alaska

The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 30 minutes delayed.

The crew was dutiful but seemed detached and bored. The boarding process is ineffective. No reason I shouldn’t be able to sit with my wife. I checked in at the first available minute and still got boarding tow “C”. Southwest used to be my first choice due to value. But no longer. Southwest is like traveling in a cattle car. Suggestion: be the first to make Wi-Fi free!

wifi wasn't working correctly so couldn't watch live tv

Terrible. Plane was at gate for 30 minutes before boarding. Boarding took 30 min. Then the co pilot announces that the plane has the minimal amount of fuel it needed. So we waited at the gate on board without air conditioning for 42 minutes while the plane took on additional fuel. My question to Southwest Airlines. Why didn’t you add the fuel to the plane before you allowed boarding to a plane without air conditioning in 102 degree heat.

Flight was not full! Had a whole row to myself.

Since the flight wasn’t full, we had some extra room. Crew was great

There was over a 9 hour delay for one thing after another. A toilet problem, they had to change the brakes, they had to refuel, three pilots times out, etc. We had to sit on the plane at the gate for over 5 hours with no air.

Tight seats. Be prepared to sit in the middle if you are in boarding group C.

Southwest Airlines is behind the times with a woefully inefficient service animal policy that leads to major inconsistency and stress for passengers and crew alike. Despite so many attempts to share feedback and request better support, they bungled it once again and provoked a panic attack in the process, with no apologies or acknowledgment that their crew was failing to adhere to their own inadequate policies. WiFi didn’t work, flight was delayed by an hour, it was about what I’ve come to expect from Southwest these days.

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.

Was unsure of this flight due to high winds in CVG from Hurricane Helene. Crew did a great job of getting us to CVG safely.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

Don't waste your money or points on first class. Delta first class is a joke. The seats were rickety, the food was awful, and nothing worked, wifi, my light, the power plug - and it was dirty - the fold out table was gross. For 2-3 hours, tough it out in Economy.

Long line to check bags. Curbside check-in was closed. Seat back monitor was not working.

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

Overall, the flight from Atlanta to Orlando was acceptable, albeit delayed and the typical temperature issue on the plane (hot) which has become somewhat expected. However, the staff at gate B22 for connecting flight DL1562 was disappointing. And to clarify, there were two gentlemen behind the counter — one pleasant and the other, Larry. Without question, Larry should not be in hospitality. My wife and I were first in line and when Larry walked in behind the desk, my wife greeted him with “Hiii Larrry”. And while she can be bubbly at times, and I get that it was late, the conversation morphed as Larry asked if she was drunk. At first I assumed he was joking (still not appropriate) but he was not. Clearly he was having a bad day or maybe just hates his job. In all cases, his behavior was unacceptable and offensive. The only saving grace is that he was equally rude and dismissive to all of the surrounding guests as well—although, I’m not sure if that is a good thing or not.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

Delay getting into gate in ATL caused delay in bags when getting to BWI, disrupting evening plans with family.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

In this flight we had selected seating for our family in the middle of the plane in a 2x2 format. The airline changed them to the very back row of the plane and split them to 3x1. Why pay for seats that allow seat selection if the airline will just move them to the worst seats in the plane?

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The plane was delayed ~ 40 minutes. Communication could have been better. The entertainment was poor. We were not offered headsets by the flight attendants. The arm rest pad did not work properly, thus, I could not select what I wanted to watch.

A/C wasn't working. Made the 1.25 hour flight seem like 4 hours! Even at altitude it didn't cool down.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

See my previous comments. I was probably booked in business but was moved to economy

No water on the toilets, dirty sits. 4 hours delayed departure.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

The flight was delayed, but other than that everything was fine.

Seats had more cushion in this flight. Otherwise, I got what I paid for. Will avoid spirit airlines at all cost.

This is the first and last times I take spirit. It’s really bare bones. That old saying that everything comes at a price, that’s really applicable here.

The first flight was delayed which would've caused me to miss the connecting flight. It wasn't the first delay of my overall trip with spirit airlines. They were both due to crew. I was offered a credit after I cancelled my newark flight, but honestly, I won't be flying with them ever again. It's absolutely ridiculous that a full refund isn't given considering it wasn't something mechanical or weather related. It's literally their own crew being late.

Well, the seats were SO tiny. I’m five-foot ten-inches talk as a woman and thank god I wasn’t more than 150 pounds as I would not have fit at all. I understand there are the “big seats”for an upgrade or a blocked middle seat but I was not prepared for the size. Also, there was an incident on the plane with a man who wound up being escorted off the plane at landing by TSA… I understand this was not in the control of the flight crew BUT the flight attendants were arguing amongst themselves at the front of the plane and we could hear them. There was a flight attendant in her 50s scolding a male flight attendant for “placating the guy” that was causing a ruckus and telling him “you should have been on our side not his.” Not only was this unprofessional to do in front of passengers, but it caused anxiety in nearby people including myself. We don’t want to feel like there is a potential danger on the flight - 9/11 flashbacks. The flight crew should remain calm and I believe the male flight attendant was in the right in trying to calm the man who was an issue.

Comfortable and plenty of. Having to buy water and coffee, though is ridiculous!

Could at least have little recline in economy seats and windows to the last row, they were super uncomfortable and lots of chit chat and disturbance from the operation of crew members and other passengers

Doubt that you care, the flight from OAK to Las Vegas took longer on the runway when we arrived. The flight attendants & pilot announced that they knew a lot of us were getting on a connection to Dallas & that it was waiting for us. Lied. Ended up having to take another layover & it’s added way more time to my flights. The ticketing staff at the gates were extremely rude. I don’t think I ever want to fly Spirit again.

Spirit airlines flight delays caused me to miss my connecting flight. I was rebooked in a different flight that routed through Texas. The flight from LAS to Houston was miserable, the person seated next to me was visibly intoxicated, and was served more alcohol in the plane. Upon arrival in Houston nothing was open, even TSA. I had to spend 6 hours just waiting in the airport. All in all, I arrived home a full 12 hours after my originally planned travel which out my family in a bad position. Do better!!!

Time in the air good, but waited on the tarmac on arrival for 35 minutes before access to the gate.

Cancelled my flight and left the airport 30 minutes earlier than time was scheduled for and wouldn’t let me on the plane when i showed up to the gate 25 minutes early

There was extremely long wait times to check in my bags and pass through TSA. I almost missed my flights on several occasions.

Booked two aisle seats and were switched to an aisle and middle. Not happy.

Flying Frontiier was extremely poor!! I paid for a7:15am flight on flight 1601 from PHL To Las Vegas and the delay was brutally, excruciatingly and disgustingly long (8 hrs). I arrived by Uber to PHL at 5:30 am and had to spend the entire 8 hr delay inside the airport. Even more atrocious was that the flight was delayed twice. On the phone with customer service for two hours and was not fully compensated. I feel taken advantage of with this airline. They offered a menial couched for another flight within 90 days to me and my husband who has never flown but this experience has made us almost 100% sure to not fly this airline and will suggest that others don’t either. We don’t want to book ever again, don’t want a menial voucher and I believe by standard and because the flight was delayed for 8 hours, I should be fully reimbursed for the entire round trip. There is no excuse why this should have ever occurred. After sharing my experience with others in Vegas and Philadelphia, I was told that Frontier airlines is notorious for long delayed flights, poor customer service and refusal to compensate people correctly. I’m very nervous to see what departing from Vegas to Philadelphia will bring.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Gate agent for Frontier in Sioux Falls was horrible. Some people shouldn't have jobs where they need to work with people. This person tried to control everything and even argued with a Sheriff's Deputy. He seemed to write the law and think he was immune to everything and could do whatever he wanted. What a miserable experience for a lot of people. He even delayed the flight just for on his own actions. The pilots made up the time lost, but why does this person have this job. Apparently nobody cares at Frontier. We do, My wife said she would never fly on Frontier again.

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

Did not realize seats did not recline. Best to travel in an exit row... No question

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline
