Pros: "Very attentive and professional crew."
Cons: "The cabin was EXTREMELY cold!"
Cons: "Good flight smooth sailing! On time"
Cons: "I really hate how bad Southwest WiFi is, wasn't working again. Additionally, the plane was an 800 series jet, basically new, and has this loud music playing during boarding which makes trying to get a last phone call in impossible. What is wrong with a little quiet?"
Pros: "Decent flight."
Cons: "Slow boarding, delayed flight."
Pros: "Excellent customer service."
Cons: "No complaints!"
Pros: "Half an hour early and smooth flight."
Cons: "Snacks were limited, but they were free so in comparison to other airlines it’s hard to complain about this."
Pros: "on time and attentive crew"
Cons: "bumpy ride"
Cons: "No reserved seating"
Pros: "I eventually made it home. They also kept the lights off."
Cons: "The flight was severely delayed, and I ended up arriving home over five hours later than expected, at 2:30 a.m. The first flight was pulled off the runway."
Pros: "Flight was on time, plane was clean, flight attendants were courteous and helpful, snacks were more ample than other airlines."
Cons: "We were supposed to leave at 10pm and our flight kept being pushed back. We didn’t get to leave the airport until 2am without an apology, a voucher of any kind. It was a huge inconvenience. I had just wished Southwest would have stepped up their hospitality game on this one."
Cons: "flight was late, no drink service"
Cons: "Plane ac was not working... seats extremely thin hard for little by rides"
Pros: "Checked bag included. Bigger, more comfortable seats compared to other airlines."
Cons: "Everything was good!"
Pros: "Flight was delayed out of Denver by 45 minutes. Believe it was storm-related, beyond their control."
Cons: "Lots of "bumpy air" that turned out to not be the case. Flight attendants were seated most of the flight, and our kids got really testy when we ran out of food and drinks for them."
Pros: "Everything was great"
Pros: "Loved the crew, extremely friendly and had a sense of humor."
Pros: "Typically efficient operation. The airport staff and flight crew were the usual friendly and accommodating folks I have come to expect. The snacks have gotten worse over the years, but it’s the same across most domestic airlines. I feel fortunate that Southwest still allows you to check luggage w/o additional charge."
Cons: "I vacillate about open seating."
Pros: "Great staff!"
Cons: "There was a bit of a delay to do with the plane. But you can’t avoid things like that all the time."
Pros: "Friendly staff! Got to Atlanta early too!"
Cons: "N/A"
Pros: "Crew is always very helpful especially with my kids"
Cons: "Wi-Fi didn't work, family boarding is after all the As board which is so wrong. Priority boarding should be for families with kids under 6"
Cons: "Bossy lead flight attendant and the mid-cabin was very cold and not corrected even when a number of people asked."
Pros: "I enjoyed the service"
Pros: "I suppose we prioritized safety."
Cons: "We were very late because the crew had to ask for everyone on board's ID and names. It seems there may have been a security issue, but it wasn't clear what was happening. Folks missed or nearly missed connections - clearer communication could have helped."
Cons: "The trip was fine"
Cons: "Everyone is always smooched in like sardines, but it's like that on every flight."
Pros: "It was on time and the service was good"
Cons: "I just abhor the fact that you have to que up for seats. yuck.. I only fly Southwest as a last resort."
Pros: "Excellent"
Pros: "It was really quick and easy."
Cons: "We had to finish our drinks early due to potential turbulence."
Cons: "Checked bag came back ripped"
Pros: "Delayed by 2.5 hours - every 30 minutes or so we got an update saying it'd be another 30 minutes"
Pros: "The cookies are good?"
Cons: "Horrible flight. On one of the newer planes (trays in arm rests) A 'customer of size' came in on the tail end of boarding and was seated next to me. The problem is that on bulkhead seating, the arm rests don't move up so it looks like they're sitting ON the armrests which means I'm leaning into the aisle and the person by the window is squeezed. However, other seats (middle) exist and no accommodation is made. There's also a policy that a COS procure an extra seat, for their comfort and comfort of others. Guess not, and when pointed out, the FA shrugged and asked if I want to move. Sorry, but I bought business select because I wanted a certain seat (get off fast, aisle, leg room). So instead of recognizing the policy, instead of making sure the COS is in a comfortable seat, instead of asking someone else to move where the armrests can be lifted, etc. She gets to sit nearly on the arm rests and negatively impact (aka wrecked) the flight of two business select customers (A4 and A2) Really?!?"
Pros: "Everything"
Cons: "N/A"
Pros: "Crew was fantastic! Courteous & fun!!! I always look forward to flying Southwest ❤️"
Pros: "Everything except the lack of WiFi"
Cons: "No WiFi. What's the deal??"
Pros: "I liked the AmEx lounge in Seattle."
Cons: "Not a great amount of choices for food here in KC airport."
Pros: "NOTHING"
Cons: "DELAYED 4 HOURS..COMMON Was travelling with my 86 yr old mom!!!"
Cons: "Second flight didn't have WiFi even though they had send an email that it would have. Boarding the second flight a woman jumped ahead of many people and the boarding agent let her go. Why have priority boarding if it is upheld."
Cons: "Two gate changes, 55 minutes late, no explanation."
Pros: "Southwest Airlines just became my most favorite airline compared to united and delta although it doesn't have lots of schedules. The humor and flexibility won my heart."
Cons: "Other than the schedules, it is great."
Cons: "On longer flights, the new normal seems to be to keep passengers locked in their seats with the seatbelt sign illuminated even with no turbulence. On both flights, it was over an hour from take off and an hour and a half after boarding before restroom use was available. Particularly on the Atlanta to KC leg, there simply was no turbulence to justify that action other than shortening the time of service and keeping the aisles clear of traffic for the flight attendents. On de-planing, we were routed in the opposite direction of baggage claim before being allowed out of the secured area requiring a terminal long walk back to our bags. If there is an order or suggestion to the crew to keep passengers in their seats other than solely for safety, SW should discontinue it, Having said all this, still a big fan of SWA."

I like the leg room. Coffee was so bad that it gave me stomach pain.

Cons: "Better business class seating, better food and in seat entertainment as it isn’t enjoyable watching movies on an iPhone."

Pros: "Everything went smoothly."
Cons: "I was NOT happy to spend over $100 for two bags for two passengers."
Pros: "Staff was very attentive at checkin and gate. They were ready for me before I was ready for them! Flight crew was also great. Seats comfortable, plenty if legroom in coach."
Cons: "Everything was excellent - but having not flown Alaska, I was expecting something exceptional. Top rated US carrier, and inheritor of the Virgin America legacy, I expected something more. I've flown VA, and it was an exceptional experience."
Pros: "Smooth flight, easy on and off."
Cons: "Staff could have paid a little more attention to what the were doing. Asked 3 times for apple juice and got orange juice. By time I realized what he had given me, he was gone ☹️"
Cons: "My 3 suitcases were missing"
Pros: "Kind crew and comfy seats."

Pros: "Crew was fine. Plane was fine. Boarding was okay, but late. They did give us an upgrade in seating on a flight to Salt Lske since they were late arriving at Seattle. The"
Cons: "Sat on ground for over an hour at Dulles A luggage problem wad the rationale. They was some inclement weather, but they knew it was coming and should have been prepared. Upon our late arrival at Seattle there was no one to direct or expedite our attempt to make our connection. There was no attempt to help us make our connection. Instead of arriving Helena at 3 pm., it was midnight."
Pros: "There was plenty of legroom, cabin crew came often for drinks, snacks and trash, power outlets easy to access (below tray table)."
Pros: "Every aspect of the trip was above our expectations, comfortable seats, delightful staff, good food and on time service."

Cons: "Crew was rude and very unhelpful. Made smart little comments to many passengers."

Cons: "I wish they would provide more food options or at least stock a few more of the ones they have. The fruit and cheese tray sells out early making it a long flight without real food. I don’t consider chips and cookies lunch food."
Pros: "One beverage cart pass during a very long flight. No food available unless preordered. Not even the obligatory mini pretzels."
Pros: "Comfortable seating, tv screens in seat backs."
Cons: "Like when captain points out landmarks every now and then but this crew did not. Minor complaint if I had to have 1."

Cons: "Very good"
Pros: "The flight attendants were very friendly and attentive. The Red system makes the flight much easier. It has entertainment, you can order your food and keep track of the flight stats"
Cons: "The plane had problems delaying the flight by 3hrs. Alaska really should change how they load the plane. After all the special people (first class, mvps, etc.) then passengers without carryons then people with carryons.

Pros: "Arrived about a half hour early"
Pros: "I would like to possibly see some better food options maybe for people who can not consume dairy. With the many different cheese platters, I was very uninterested. I had an early flight and thought I'd be able to eat something with a sort of substance. I was quite disappointed, I guess I'll have to be the annoying customer who brings chipotle on the plane next time."
Pros: "The flight crew was very friendly."

The company rerouted a different plane to take us since ours was going to be so late, turning a 2 1/2 hr delay into just a 1 hr delay. Boarding was super efficient, in flight service excellent. They comped us our headphones because of the delay, a nice touch. This is my 3rd great customer service experience with JB in as many months (the other 2 involved waiving charges to change flights, once gor me when I was suddenly ill, and for my cousin, when a changed circumstance made her need to travel on a different day, alone with 4 kids). Between Kayak and JetBlue app I got very frequent updates on flight status, but gate staff also were there and informed us in person."
Pros: "Our flight was delayed a bit but that was not a problem for us-gave us a chance to have some lunch. All of Jetblue’s Staff from the res agent at the counter, flight attendants and crew were all very professional, courteous, pleasant and helpful. Uniforms very nice. Thank you."

Cons: "This wasn't pertaining to the flight or airline; but the TSA line was ridiculously slow."
Pros: "Good choice of video programs."
Cons: "The flight attendant took 25 minutes to appear, and had enough time for one round of service. First class, at least you should get two drinks. Fly basic economy, there just isn’t any reason to fly first class."

Cons: "1st class was horrible."
Pros: "i fell asleep until we arrive to STL."

Pros: "Flight attendants and cookies. That's it."
Cons: "We left DC late because of Delta's inefficient boarding process. We landed in Atlanta late. Our flight to Sioux Falls left early, without us. My pregnant wife and I made it to the gate 4 minutes before the scheduled departure and they told us the plane was already gone and there was no way for us to get on the plane. Our bags did make it to Sioux Falls, so my wife didn't have her prenatal vitamins, , we had no clean clothes and we were forced to spend the night in Atlanta. The saddest part of yet another terrible experience with Delta was that they offered us a "discounted" room at a terrible Howard Johnson for $72. I looked online and the same hotel was $65 to book on Kayak. So basically Delta was trying to scam us after they screwed us. Thanks Delta! Instead we paid $200+ to stay at an airport hotel. Every time I fly Delta I regret it, yet occasionally I get forced to take their awful airline to get somewhere I need to go. It never fails to add another bad Delta experience to my long list of failings from this SAD!!! airline."
Cons: "There delay"
Pros: "For a short-haul flight on a small CRJ, it was the most pleasing and comfortable flight. No delays and everyone was pleasant from ground staff to flight crew."
Pros: "The crews were very friendly and everything went as planned. It was a nice flight."
Cons: "I didnt like that my flight was canceled and rebooked for no reason. This created me big problem in Athens that they couldnt find my ticket in delta. Also I didnt like that i had to stand and wait for 3 hours in the line because my flight was canceled but no one could let us know if there gonna be any flights within the day. I slept in the airport because i couldnt find a hotel to spend the night close to the airport. They were all full and i had no time to find one since I was waiting there for 3 hours with no informational. I slept on the floor and delta didnt even offer us a blanket. That was my worst trip ever."

Cons: "Nothing everything was fine"

Pros: "Crew service was excellent"
Cons: "Poor leg space"
Pros: "On time, nice crew."
Pros: "I am 6'6" 300 pounds ... So I regularly book first class for trips over 2 hours in length ... Delta remains my #1 choice for both value and overall experience in first class. The difference between Delta and all other domestic carriers is just overwhelming. United and American/US Air could learn a lot from Delta. I could have flown this trip direct on United, but chose to fly through Atlanta on Delta for less money and a better experience from the baggage check to the gate to the in-flight experience."
Pros: ".....delta in Washington was great changed my flight so I didn't have delay !!!!!! Will always use"

Pros: "We arrived ."
Cons: "budget airline with terrible service. I did not make my return flight due to their line moving so slowly - took 2 hours in line to be told I didn’t arrive early enough. Many people in the line missed their flight - no refund and no help. Booked with another airline - not flying Suncountry again."
Pros: "The crew was great!"
Cons: "I had to take a bus from my gate to the plane from the new D21-26 gates."
Cons: "Got another plane or somehow figured out a way to get us home instead of being delayed 6 hours."
Pros: "On time and comfort of leg room"
Cons: "The gates are at the far end of the STL terminal"
Pros: "Tickets are cheap but you have to pay for your carry on"
Cons: "Would like to have had tv in seats,"
Pros: "Direct flight"
Cons: "Small seating-our knees were sore when we got here."
Pros: "Boarding was easy and the flight was comfortable."
Cons: "The upcharges for carry on and a “seat fee”. My flight costed $100 extra!"
Pros: "Price"
Cons: "Flight departure was late. No entertainment options."
Cons: "My knees knocked into the sweet/ no legroom"
Pros: "Nothing- and it cost me $50 to have voucher issued for future flight."
Cons: "Monitors with Sun Country gate information very difficult to find, if at all. I asked several people about Sun Country and departure gate, and was pointed in several WRONG directions. Since next flight out was 9p, I decided to cancel my trip. I did investigate taking same flight tomorrow, Jul 13, and was told it was full and I would be standby."
Pros: "The service was quick and friendly"
Cons: "There is no wi-fi"
Pros: "Sun Country is a good airline."
Cons: "That Sun Country is charging for carry-on items."
Pros: "Friendly crew. Pilots kept us updated on potential turbulence and weather- but it all went well."
Pros: "We left on time. Boarding was quick. Air travel was mostly smooth. We arrived a bit early."
Cons: "No gate agent available when we landed. Baggage took too long to unload. Only water offered during flight. We could only check in after 9pm for our midnight flight."
Cons: "We were almost 20 minutes late arriving in Ft. Meyers and there were at least six babies or toddlers who screamed for the entire 3 hour flight. While that's the fault of Sun Country, it was very unpleasant. Also the carryon restrictions are ridiculous. I feel that Sun Country is extreme in allowing only one bag that fits under the seat. That's why all of the overhead bins were empty on a sold out flight."
Pros: "Direct flight. Being on time."
Cons: "No food or entertainment. Not much leg room. Baggage policy"
Pros: "I had a seat toward the front, so I boarded early-ish, which went smoothly."
Cons: "Seating was incredibly uncomfortable. The bottom cushion was worn down, so my butt was sore after just a three hour flight. Also, my neck and back were in pain after getting off the flight. I am in my 20's and don't really get sore neck or back, but the seats were just that bad. However, I did have JUST enough leg room even though I am 6'4". I'll probably avoid this airline in the future just for the horrid seats alone."
Cons: "I’m not sure why an airline, in 2017, doesn’t have WiFi available during the flight."
Pros: "Boarding process was expedient."
Cons: "No advanced check-in for flight available, changed my seat & didn't tell me until I handed attendant my boarding pass, was switched to a seat in the first row of economy cabin so hard dividers between seats that didn't allow for ease of comfort to relax for long flight, flight was FREEZING cold, asked for a blanket and was told there were none, only breakfast option was disappointing"
Cons: "Plane was 1.5 - 2 hours late and passengers were offered no explanation and there were no apologies from the crew. Even if it was unavoidable (weather, etc.), SOMETHING should be said to passengers. Very poor customer service."
Cons: "No email was sent to me inviting me to check in. Sun country site was down on 9/10 and 9/11, so I could not checkin online."
Pros: "Generous with size of carry on. Staff pleasant"
Cons: "Would like a small snack included"
Cons: "I don't like hearing that Suncountry is going to be an airline that charges a fee for everything like Spirit airlines. I heard that this will begin as of January 1st. Suncountry is a great airline. Why would you change that? It's disappointing."
Pros: "The crew was great, check in was fast, boarding was quick, flight was on time leaving and early landing."
Cons: "It was a longer flight and it would have been nice to have a tv screen or somewhere to plug in for charging devices. Also, I didn't buy any food cuz I thought I would get a tiny bag or peanuts or pretzels, but we didn't get anything."
Pros: "Very friendly crew"
Cons: "Dear didn't recline (I realize for safety)"
Pros: "It was direct"
Cons: "Sitting in the middle in a tiny seat"
Pros: "Staff were attentive and professional."
Cons: "Got a piece of napkin in with the ice for my drink. Now sure how that happens."
Cons: "Both entertainment rental and food cost high. Need to be consistent enforcing luggage bag size allowed as carry on."
Pros: "Ticket agents were fabulous, bulkhead seats perfect for my husband who has an injured leg, crew helpful and efficient"
Cons: "Had a neighbor who talked A LOT! And three crying babies on the plane. Nothing you could do, but it was far from relaxing!"
Pros: "Speedy check in and being a retired US Marine, I liked that we were given recognition and boarding preference."
Cons: "I was traveling alone and overall experience for 3hr 20min domestic flight... no issues!"
Pros: "Convenience of non stop."
Pros: "I was given an exit row seat"
Cons: "The flight boarded 30 minutes late, then deaparted over an HOUR late."
Cons: "Late boarding time"
Pros: "The customer service was excellent! I convince others To try you because of the customer service."
Cons: "Too much wait time!"
Pros: "On time polite counter staff awarded me a good seat."
Pros: "The friendliest service and very accommodating when I asked about a seat change to sit next to two other friends. I wish all airlines has this great customer service!"
Pros: "Only the price and was not that cheap after addn fees."
Cons: "Boarding strategy leaves rows 11-20 without over head space. No one puts their "non-rollerboard" under their seat so now under the seat is empty and heavy roller boards have no space."
Pros: "No snacks offered, just the essentials"
Cons: "It was painless"
Pros: "Friendly and helpful. Great service."
Cons: "No free entertainment. Glad I brought my book."
Pros: "I liked efforts to load the back of the plane first! Crew were friendly."
Cons: "Check-in attendant broke handle on my luggage and then tried to have me sign release to excused accountability."
Pros: "On time. Carry on checked at gate"
Cons: "Only beverages no munchies unless spending additional &."
Pros: "Price made it worth it! Boarding was quick. Staff was pleasant."
Cons: "Seats did not seem to recline and plane was a little old feeling."
Pros: "The last three times I've taken suncountry, I have not been able to check in online. I had to come to the airport early, and stand in a line to get my boarding pass. I wonder if this is some way to get you to buy an upgrade seat?? They said they were having computer trouble, but after three months and three tries, I'm not planning on flying them again."
Pros: "Upgraded to first class. First time ever doing that and it's the best way to go."
Pros: "Check in a breeze and staff friendly in Phoenix"
Cons: "Staff not as friendly in MN"
Pros: "Low cost"
Cons: "The flight attendants weren't very friendly going to or from my destination. They snapped at people as they pushed their cart down the isle."
Pros: "Crew, on time, wheelchair service"
Cons: "Cramped seating, food"
Pros: "Courteous staff, smooth flight"
Cons: "Online check-in does not work."
