Find cheap flights from Knoxville to Sioux Falls

Pros: "As always the Delta crew was super friendly and helpful and made the trip very enjoyable."
Cons: "Everything was perfect"

Cons: "Had to check my bag yet others brought on two bin sized pieces. Had to get seat assignment at the gate and rep was rather abrupt with instructions. Smell of fuel in the cabin. In last row which was uncomfortable"

Pros: "The crew was communicative and courteous."
Cons: "There was a flight delay in LAX due to a maintenance issue. The captain and crew informed us before we boarded the plane which was excellent. However, they could not figure out what was wrong with the planed and delayed the boarding for another 3 hours, putting our 1900 departure time to 2100."

Cons: "Almost 3 hours delayed"

Pros: "Yes"
Cons: "Snacks"

Pros: "The crew was one of the best I have ever experienced. They even had the flight deck wish a happy birthday to my 89 year old mother in law."

Pros: "Crew was great."
Cons: "Couldn’t hear/understand the pilot"

Pros: "We eventually got to Atlanta."
Cons: "Delta is flying a lot of commuter planes, which are pretty cramped. We usually fly first class, and the seating is essentially the same as what coach used to be. There's nothing "first class" about it. And of course, the flight was hours late."

Cons: "Boarding was like a cattle call....my headrest was broken so couldn’t sleep upright but face down....seemed like a plane that large would have more bathrooms"

Pros: "I got to board early because I volunteered to check my carry-on. Very friendly flight attendants. Love flying delta. They are always consistent and the movies they offer with the gogo in-flight app are always updated and recently released popular movies."

Cons: "Plane was so small I couldn’t even put my backpack in overhead and nobody told me to check it even when I asked"

Pros: "The crew did their best to accommodate for the hot mess."
Cons: "The temperature was unbearable. My dirt and pants were soaked with sweat. It was very hot."

Cons: "Sat on the tarmac for 20 Minutes, after taking off late. Arrived to my connecting gate 10 Minutes prior to scheduled departure with no delta attendants in sight and watched my plane sit at the gate and pull away with no way to get on board. Now I’m waiting unnecessarily for 4 hours on another flight."

Pros: "Boarding from back to front. Making early boarders wait to the side when they tried to embark too soon."
Cons: "All the people standing in line prior to boarding."

Pros: "The staff"

Cons: "The baggage drop attendant was very unhelpful when I asked if she could help me sort out an issue (when I checked in online for the second leg of my trip, i paid for my bag then but they wanted me to pay again for my first flight) and just dismissed me and said she couldn't help, making me pay again for my bag. First time I've ever had an unpleasant experience with Delta."

Pros: "People were great"
Cons: "Air vents and the side of aircraft felt like it was loose and falling off."

Pros: "On time."

Cons: "Late with no information"

Cons: "Nothing"

Pros: "Everything's good but the company need to improve the menu for vegetarians people"
Cons: "The vegetarian menu was very bad. I really didn't like it and was the same option to L.A. and when I came back tp Australia."

Pros: "Staff were friendly and boarding was and getting off was easy because flight was super empty. Timeliness was appreciated too."
Cons: "Seats don't recline far enough."

Pros: "The very personal pilot"

Pros: "On time. Clean."

Pros: "Very comfortable seat and nice boarding and exit."
Cons: "Not clear at all on what was complimentary, etc. Had a very large man next to me, practically sharing my seat so getting any needed work done was out of the question unfortunately."

Pros: "Please see above. Sherry was amazing"
Cons: "Plane was small and older but it was a short flight"

Pros: "Sky Lounge at SFO and onboard entertainment"

Pros: "Uneventful flight - boarding was great and there were no hassles."
Cons: "No food. No onboard entertainment."

Pros: "Delta agents rerouted me in face of weather problems in Southeast so as to allow me to make my LAX to Sydney flight. Well done."
Cons: "Not enough leg room in Economy. I lucked out on transpacific leg with an exit row seat, everything else tight. Movie choices kinda limited and very US."

Pros: "Everything went well...on time, quick boarding and free gate check of bag."

Pros: "1. Great movie selection 2. Healthy food option 3. Craft beer was appreciated 4. Friendly crew"
Cons: "1. Wifi didn't work"

Pros: "The crew went out of their way to make sure they got the plane ready as quickly as possible and get us to Jacksonville as quickly as possible."
Cons: "Delta lost the plane for over an hour. After already spending 10 hours in ATL because of an earlier delay due to human error I was extremely disappointed in Delta that my flight out of Atlanta was delayed by an hour because they LOST the plane and couldn’t find it or the truck to bring it to the gate. This kind of error on Xmas eve is embarrassing. Delta didn’t do anything for the passengers affected by this. I was dumbstruck by the apathy of the Delta employees at the gate (the exception was the flight crew, who tried to get the aircraft there earlier). Because Delta did nothing but make error after error I arrived at home 11 hours later than my original flight was booked for on Christmas Eve, missing Christmas Eve Services and family traditions. When I need to get somewhere on time I’ll never rely on Delta after this experience."

Cons: "We purchased food. Bread was stale, and fell apart in your hands."

Pros: "Very efficient boarding; crew had the foresight to ask for travelers to gate-check their bags due to a full flight and that saved a lot of boarding time and hassle."
Cons: "The seats on this aircraft looked like that had a 2-2 configuration; it's now 3-2 making it pretty cramped in Coach."

Pros: "Flight crew was good, we arrived early on flight out and back! Feel like seats are tinier than ever, maybe it was just me. Food (water & pretzels) were OK, but nothing special (then again it was a short flight, so I didn't expect anything). Plane was small so we needed to gate check bags and the gate attendant came around and tagged everyone's bag for us, well before boarding which was hugely efficient - kudos to her on that!"
Cons: "Gate attendant's mic was broken (or she didn't know how to use) so she had to yell into the boarding area."

Pros: "It was on time"
Cons: "It was crowded and cramped."

Pros: "Crew"
Cons: "Boarding process"

Pros: "Nothing. Delta is the worst. Delta is awful. Don't fly Delta."
Cons: "I wouldn't know how our flight to Sioux Falls was. Delta left without us, after they made us late. 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."

Pros: "Overall the actual flight was good..landing was kind of hard but I'm alive so not stressing that"
Cons: "..but the multiple delays are ridiculous, I would not fly Delta if I had a feasible choice."

Pros: "Left on time, plane was clean and arrived early"

Pros: "it was great experience"

Pros: "Who could ask for more?"
Cons: "N/A"

Pros: "friendly courteous staff"

Pros: "everything on schedule; courteous staff and great pilots"
Cons: "everything was very ordinary so cannot complain"

Pros: "gate and plane staff friendly, smiling and helpful."

Pros: "Service and friendliness was awesome."
Cons: "No drinks served, sorry flight."

Pros: "i love the view from the window seats and that I was able to relax and the snacks."

Pros: "Flight was quick, crew efficient"
Cons: "Despite having this flight booked for over a month I was not issued a seat until gate check in and had to sit and wait till they figured out their "overbooked" situation. I had to approach the desk four times because they wouldn't give me any indication of what zone I should line up for, and the desk crew were rude. Ended up being the last to board."

Cons: "2 1/2 hour delay; confusing messaging from staff about having to get a hotel because the delay caused us to miss our connection; but then we were told to hurry and get our connection anyway; there's no padding in the seats - very uncomfortable."

Cons: "The jerks left early despite the fact that security and baggage were backed up. We ran to our gate and barely missed the flight. Jerks! Who leaves early when so many passengers are missing?!"

Pros: "Nothing"
Cons: "Flight status"

Pros: "Nothing. As sucks."
Cons: "Planes auck. Terminal suxks."

Cons: "Air conditioning wa not working. We were in a hub why wasn't the plane switched."

Pros: "Very competent flight attendant."
Cons: "Flight was a half hour late. Pilot could have communicated with passengers. Gate 35X at National Airport is a terrible situation. We go down stairs to deplane, then wait for a bus to take us to the terminal. Not acceptable."

Pros: "Nice crew"
Cons: "Be on time 2.3/4 hour delayed no weather issues or mechanical"

Cons: "Get rid of commuter jets."

Cons: "Commuter jet—no comfort. No jetway, we were on airplane stairs."

Cons: "No boarding by zone."

Cons: "Can't fly American Airlines without a flight delay. Have to plan flight delays into my trips because every time I fly American there is a delay. Certainly encourages me to fly other airlines."

Pros: "Going on vacation"
Cons: "Tvs for all seats"

Pros: "Flight attendants were great. Special note for Payton very attentive to my needs. Great personality. I will fly AA if all attendants are half as good and responsive as she was. She definitely deserves a raise."

Cons: "Too many delays that made me miss the original time I was to catch my connecting flight. Missed my appointment in Spain as a result..."

Pros: "Stairs cause me tremendous pain due to a 4 year misdiagnosed ruptured SI joint. Usually, we have no way of knowing that our flight will end with a downstairs walk rather than a ramp. I emailed American Airlines last week but hadn’t gotten a response yet so when they announced that we would exit by stairs, I was almost in tears as I gathered my belongings. To my surprise, American Airlines had a ramp for us to use. I don’t know it it was a coincidence or if they responded that quickly knowing I was on the plane through todays’s technology. I will be a fan and a customer forever."
Cons: "On time, loaded quickly,ramp access to exit the plane."

Pros: "Efficient and on time! Courteous and professional travel assistants. Nice job. Nice new planes too!"
Cons: "Traveling as family of 5 - booked tickets two months ahead and we did not sit together despite me selecting seats when I booked. They were cheap seats so I can’t complain too much but felt that could have been accomplished given the advance booking."

Cons: "Every leg of my journey was frought with issues. From weather delays to maintenance issues. The biggest issue I have is that invariably when I fly American, if I go through Charlotte, is on the whole inconvenient. It takes way to Long to get to a gate when you land. And while everyone is apologetic, I would prefer they didn't have to be."

Pros: "Clean plane, kept cabin lights dim the whole flight until the plane was parked at the gate, and music at a good volume"
Cons: "None at all"

Pros: "An elderly lady sitting next to me with a broken arm.....was approached by the flight attendant and the flight attendant was so considerate that she took the lady to the empty seat in first class!!! I noticed this kind gesture and noted it to the flight attendant. She told me sometimes folks get upset asking why they did not get the upgrade! It amazes me....I always think if that were my mother how would I want to be treated!!! CUDOS to this Flight attendant....Thank you AA for making this gesture and God Bless you all!"
Cons: "Surprise....American Airlines no longer food nor one bag free! Well if you can stomach the not even a snack nor one bag...then Fly AA so not so bad after all. But Gate agents, baggage handlers, pilots and flight attendants take away any negatives whatsoever! Great work AA."

Cons: "3 planes all with mechanical issues... numerous people left stranded, the whole thing was a nightmare. Finally got home around 1 00 AM. But the worst part was the gate agents I literally felt like I was disrupting their day! Email sent to American."

Pros: "N/a"
Cons: "Flights from PDX to BOS cancelled. Rerouted to PHX. All flights out of BOS, DC, Philly cancelled. I missed my Habitat for Humanity trip, not getting any refunds on flights or hotels. Out thousands and no one is helping me."

Cons: "No complaints"

Pros: "Movies online you had is always awesome"
Cons: "Space on planes are ridiculous"

Pros: "Food was good, crew was friendly."
Cons: "The 90 minute delay before take off."

Cons: "Flight was delayed for nearly 5 hours. There was no accommodations for the delay, except for apologies. Very limited snacks were provided, but this huge delay cut into our reservations and vacation in our resort."

Pros: "Priority boarding."
Cons: "Food is horrible at AA, in special breakfast!"

Pros: "Pretty good dinner and breakfast, complimentary wine"
Cons: "Slow flaky entertainment system didn't work at all in some seats, needed multiple 10-minute reboots in other seats. I was unable to complete a 2 hour movie on a 9 hour flight. No internet."

Pros: "Comfortable seats, for the most part friendly crew, with one exception. Flight left right on time and landed with no extra time to taxi. That was a welcomed benefit."
Cons: "No wifi on plane and no individual tv's for movie selections. Also had to pay extra for an aisle seat. Could not select seat at time of purchase. Didn't know if I called Iberia or American to make seat selection. Confusing with two different flight numbers. One from Iberia and one from American. Passengers should be made aware of which airline they are flying on at time of purchase."

Cons: "Had to wait for pilot coming from Mexico flight for 20 mins after everyone boarded"

Pros: "everything was on tyime"

Pros: "Nothing in particular. They got me there."
Cons: "The usual stuff. Uncomfortable. Worse than riding a bus."

Pros: "Started when 7 am flight from Knoxville was delayed - multiple times until finally at 4 PM there were no options. Nobody with AA saying a single word all this time even when asked. Finally called their customer service line only to learn that I could get on another flight that left in a few minutes. Door was still open but gate agent argued with the lady on 800 line about who could ticket faster. By time they finished arguing the door closed. That began a 14 hour nightmare of bumping between flights and delays and the inevitable lost luggage. Paid for $300 hotel room at Vancouver that I will get to stay in for 4 hours. Will NEVER fly American again"
Cons: "Service, poor rebooking process, lack of communication."

Pros: "Exceptional customer service"
Cons: "No food no entertainment so that's the only reason I gave 1 star to those"

Cons: "My luggage was damaged and I have yet to hear from an American Airlines representative after I was not ok with a replacement from a luggage company that did not reflect my current luggage brand. Being in the Customer Sevice industry I know this is unacceptable, I would never replace a damaged item with one that was not like the original or ask a customer to do so. I will not fly American Airlines any longer."

Pros: "Flight was on time, crew were friendly."
Cons: "Even though paying an extra 82 dollars per seat for emergency exit as i am tall and need the leg room, the seats did not recline. Extra cost, less functionality."

Pros: "The quick boarding and kind flight attendants"
Cons: "Seat wouldn't recline. Somewhat nauseous smell at first."

Pros: "For the price I got my ticket for. This was a good deal. I paid extra to upgrade to main cabin extra but well worth it."
Cons: "Got food and drinks and beer at nomadditional cost"

Pros: "The friendly personal"

Pros: "Swift boarding."

Cons: "On a 5.5 hour flight, a snack would have been nice. Crew needs to be friendlier like in the old days."

Cons: "Flight cancelled to begin the trip. They did however help us get a flight on Alaska to get us to los cobos"

Pros: "Smooth flight home from Cancun."
Cons: "Late arrival."

Pros: "Uneventful"
Cons: "Prices, of course. No one wants to pay the prices. My company is small and we check pricing all the time."

Pros: "They got us seats on a Latam flight later in the day."
Cons: "I don't like being bumped from a flight when you have e-tix in hand from a month previous purchase for three travelers."

Pros: "All flights were on time and the flight each way was very quick."

Cons: "missed the flight, traveling with 2 young children. Had to wait in Miami overnight"

Pros: "Nothing"
Cons: "Not updating flights at the airports or apps, our 3 flights that we tried to take to get us home were canceled I had to fly stand by ALL day Saturday, went through security three times, and have been standing at a ticket counter for ANOTHER DELAYED flight. I am disgusted and will NEVER fly American again and will let friends and family know to fly SOUTHWEST"

Pros: "Overall smooth trip and congenial staff."
Cons: "This is coming from a western audience but there could have been more entertainment options."

Pros: "Aircraft was safe, clean and good media selection with power-outlets for mobile device. Good updates from the pilot and crew."

Cons: "no in flight entertinment"

Pros: "Time of flight"
Cons: "Laguardia airport."

Pros: "I called to change my flight to an earlier time due to flooding in PA. The lady who helped me did an equal exchange for my ticket and waved the $200 fee. I was extremely pleased and appreciative. Also, excellent movie choices and food options. I will definitely continue flying with United."

Pros: "Very pleasant staff food was pretty good"
Cons: "No complaints"

Pros: "I always enjoy the staff; they are always pleasant."
Cons: "Not being told about the 3 hour delay until I was already at the airport."

Pros: "No surprises. Always informed of what comes next."

Pros: "Lost my baggage at San fransico and your connecting flights give you 30 min at most to get across an entire airport honestly I was so mad at the end when I finally got my bag I was missing a wheel of all things just poor organization for a business that takes in as much revenue as United does"

Cons: "The flight attendant was unusually pushy about the emergency exit. I am a military member who is fit and flys in the emergency row as much as possible. The attendant threatens to move me because I didn’t know what section of the aircraft the overwing exit was located."

Pros: "United got me on flight 3 hours early AWSOME"

Pros: "Friendly flight attendant in back of cabin,"

Cons: "The departure moved to three different gates. Inconvenient."

Pros: "boarding, flight attendant very nice"
Cons: "narrow seat, small aircraft"

Cons: "Purchased a non-stop flight leaving at 530 and arriving at 6:30 pm. After flight was pushed back to 830 pm departure, it was pushed back again to 1130 pm departure and 1230 am arrival. Rebooked through connecting flight and arrived at midnight."

Cons: "To make meetings, got routed to Omaha, rented car and driving to SIoux Falls. United' best flights arrived next day about 2:30pm which misses business mtgs and most of day. Had to go to customer service supervisor to get hotel room covered in Omaha. No help on rental car. No help with hotel charges already made in Sioux Falls"

Pros: "Non stop"
Cons: "Plane was small for a2:55 flight"

Pros: "On time - small plane. Ground crew performed well"

Pros: "Snacks were good for a short flight"
Cons: "Flight was delayed and overbooked. It wasnt the first time the flight was delayed. Flight going was also delayed. Attendants seemed to be in a bit of bad mood but were overall ok i guess. It was a short flight so it didnt matter."

Pros: "Friendly staff"

Cons: "We were delayed almost 2 hours. Sick of it every time I fly. Get it together. I missed my ride and had a 6 hour wait for a bus. Ridiculous!"

Pros: "Get to Denver, they tell me I don't have a seat, they asked me if I wanted to fly out the next day because they over booked met three other people who had been there for 10hrs because they did the same thing to them! One girl told me they told her it was because we paid less then other people! A nice couple stayed so I could come home. I was pissed! My daughter flew into Houston, the flight was late getting in to LA, by two hrs, missed her connecting flight to San Luis Obispo, her sister had to drive down 4hrs to pick her up and drive back because she had work! Not happy!!!!"

Pros: "The upgrade to first class, courteous staff, on time arrival, timing of the flight for a red eye. *Note I paid for the upgrade to first class. Totally worth it!"

Pros: "We arrived safely in fort Myers which was the most important part! The plane was very clean and I like the leather seats."
Cons: "The flight was delayed waiting for an aircraft."

Pros: "Everything was on time."
Cons: "Despite wearing a down coat, scarf, and hat, and holding my bag in my lap, I was freezing cold the entire flight. This was after the flight attendant let me move towards the back of the plane so I could be warmer than sitting up towards the doors. A December 6am flight with no heat? Ridiculous!"

Pros: "Was supposed to be a larger plane.. uncomfortable seats. Too close to each other."

Cons: "Flight was delayed for water leak. Two hour delay"

Cons: "Missed my connecting fight due to my aircraft having malfunctions, as well as my flight home being delayed three times. Worst flying experience to date."

Pros: "Normal things"
Cons: "Making us wait for 3 hours to take off. Did not offer anything in denver."

Cons: "Purchased tickets 4 months before this flight for a departure time of 6:05pm. Tried to check in and check baggage at 9:30am but was turned away saying I could only check in 3 hrs prior to my flight. Came back at 3:00pm to check-in and they could not find my information. An hour later they find out that they cancelled the flight and moved my departure time to 8:25am for that day. They say they emailed 3 times in May but I never got it (I'm a bit crazy about my email staying clean) so they say it might have went in to my spam folder due to they types of emails they send to customers. They only kept repeating that they notified me so there is nothing they could do. I ended up going to Air Canada to get a flight from PHX to RNO the next day. No apology, no help, no hotel for the night...Terrible experience by United. They gave me a customer relations group contact information to follow up with for complaint but since they sent me the 3 emails in May about the change, they have no liability to fix the situation."

Pros: "Nothing"
Cons: "Terrible flight. I payed for an upgraded seat, list my flight due to a crew on previous flight being late then was put on standby on this plane in a tiny seat next to someone else. We sat on the runway for 45 min. There was an open seat in row 1 that I could have been seated in, but no one offered"

Cons: "I am only 5 ft tall & petite but felt like a sardine with my knees hitting the seat in front. The overhead bins were so small that they couldn't fit carry ons efficiently so everyone was scrambling for space, delaying the boarding process & heightening frustration & stress. Boarding process was also inefficient causing delays."

Pros: "The crew was competent"

Cons: "Flight cancelled due to weather at ohare despite the fact that many other flights were still going. First delayed, sat around for hours, then cancelled almost 3 hours post scheduled departure time. No hotel voucher provided. Rebooked, but not done correctly so when I tried to check in, it was discovered that I didn't actually have a rebooking, requiring additional calls and second rebooking."

Pros: "Easy process with no delays"

Pros: "Pilot was very nice!! Co-pilot too!!!"

Pros: "Every thing was ok"

Pros: "Flight attendant was welcoming and fun."
Cons: "It was a smaller plane and being in the very last row meant I smelled the bathroom. The door was literally within arms reach."

Pros: "Landing was excellent"

Cons: "My flight to Dulles was delayed and I would have missed my connecting flight to Houston. I revised my flights to American. No alert from United that I would miss connecting flight due to delay"

Pros: "Great crew, nice aircraft to fly!"
