Find cheap flights from Knoxville to Costa Rica

Cons: "The pilot take off, navigation in the air, and landing were horrible ."

Cons: "My sister’s checked in luggage was in poor shape when we got it in Albany. We noticed an outside compartment was unzipped. So we checked to see if anything was missing and a souvenir from Mexico was gone. Then we realized a zipper was missing from the luggage and then decided to check all the other compartments and realized her bag of jewelry was gone. The woman at baggage services in Albany told us Delta is not responsible for lost belongings. Also tried to tell us theft is not an issue because there are cameras everywhere. Well you are telling someone that is missing a bag of jewelry that theft is not a problem. Also, there may be cameras everywhere but I doubt anyone is going to review those cameras to see what happened. I will never fly Delta again."

Cons: "We were seated right behind the delta comfort+ and saw the special snacks they got. Being teased by that is not a huge deal, just a little disappointed by the regular snack selection, the snack mix was definitely subpar."

Cons: "nothing to say."

Pros: "Getting home in one piece"

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."

Made the 6 hour flight go by quickly and not mind the bumpy air in the tropics."

Pros: "The crew friendly,boarding was easy the flight was comfortable they even went around and gave blankets they could do a little more with the snacks. There were TVs so the entertainment was really good. Seats didn't go back, wish they did."
Cons: "I wish they had more snacks like JetBlue but all was fine."

Cons: "I prefer personal entertainment systems."

Pros: "Late takoff"
Cons: "Late takeoff"

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."

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: "The touch screen for the video monitors need to be replaced. It was very difficult to select a movie."

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: "It was a very good fight"
Cons: "I didn't like the fact that the gate kept on changed 3-4 times and that it was delayed for an hour"

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."

Cons: "Provide food would be better"

Pros: "Plane was brand new. Nice to flight in a plane like this"
Cons: "Unexpected changes in the boarding gate, not clearly notified"

Pros: "Have a great trip without any problems."

Pros: "Swift boarding."

Pros: "Great crew today. As I was walking to the gate, one of the flight attendants that would be working this flight advised someone that was hurrying through the airport that they dropped something. While others may not have noticed or said something, she went out of her way to make sure the item got to its owner. It is little things like this that make life a little better."
Cons: "The thirty minute wait for luggage (which sometimes is quick for American at DFW)."

Pros: "we had all the necessary conditions for work, rest, sleep and eating. The level of service has increased"
Cons: "Nothing"

Cons: "it was not clear that finnair was being operated by american airlines. when I arrived to the airport in Paris, they couldn't locate my flight on finairr or american. my flight was missed and the staff on both airlines (finnair and partner american airline) were soo unhelpful. I have never missed a flight, I travel for work, in the air, more than on the ground and this was the WORST experience I have ever had. I was super disappointed that even after all the mistakes, no one would help me find a new flight and I had to pay for another one. Even after calling finnair several times and pleading for some answers or help."

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 were on time"
Cons: "The A321 had the most cramped seating I've ever experienced. The video in the seat back didn't work properly going or coming back. Boarding was slow. I don't know why they don't load the rear seats first so you don't have to wait for everyone ahead to secure their carry-on luggage. If they didn't charge so much for checking a bag there wouldn't be so much carry-on baggage"

Cons: "Food"

Pros: "Inflight movies"
Cons: "None"

Pros: "The food and the crew"
Cons: "Entertainment system, it is outdated"

Pros: "Amabilidad de la tripulacion"

Pros: "Clean, comfortable and on time."
Cons: "Nothing"

Cons: "No screens in the seats. Food options are the usual limited fair"

Cons: "Mediocre snack"

Cons: "I didn't get to get on the flight."

Cons: "Slow boarding, no food no drinks, no tv."

Pros: "Nothing"

Pros: "Más espacio, al menos una película que ver, y algún bocadillo por ser un vuelo de tantas horas"

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."

Cons: "Long delay in Knoxville because of atc clearance issues and there is not much to do in the terminal. Only give snacks and water would of rathered a sandwich"

Pros: "Entertainment worked on this flight! And once again, I had an empty seat next to me - that's always a huge plus so I can stretch a bit."

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

Pros: "The plane took two hours to leave the ground due to weather. This was unfortunate and made the passengers uncomfortable but it was not the fault of the airline."

Pros: "Very smooth ride from take off to landing"

Pros: "Accommodated me with a hote and food voucher"

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."

Pros: "First flight delayed once board to check a broken light. Then waisted 40 minutes taxiing on tarmac in Houston because they couldn't find a gate. Missed our connection. They put us up in a low end hotel overnight. Then we had our morning flight again delayed as we waited for planes to the take off, so further delays. Arrived in Costa Rica 1 hour late. Now with too many other flights so immigration packed and took another hour and twenty minutes (when we finished there was only a 5 minute wait). Thanks United"
Cons: "Coffee and cookies. Moscow mule"

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."

Cons: "Snack offering was caramely sugar cookie"

Pros: "Friendly staff"

Cons: "Fligh delay."

Pros: "I was allowed to get off the aircraft to collect a bag I left behind"

Pros: "Attendants were amazing"
Cons: "We spent the whole delay on the plane and wasn't notified of a problem until after an hour. A lot of my time was wasted. That's not okay. Keep your customers informed."

Pros: "Nice and comfy seats, good service on plane, fast boarding"
Cons: "No good food and the entertainment was not the beat"

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!"

Cons: "Same. No ffood ..poor Service and allso charging. To much for extra weight. $200 for 3 extra pounds. Ridiculous. Also charged for one check in bag..Todo much"

Cons: "Viajar en United es desastroso. Los asientos son demasiado pequeños, yo mido1.57 metros y no me podía ni mover."

Pros: "The crew were nice though exasperated with cramped new planes and crowded restrooms. Flight was on time"
Cons: "After three years of flying all around US, realized United is the worst of the three major legacy carriers. I'm star alliance gold and it's still a painful experience. Crew admitted in latest redesign of planes they've managed to squeeze another six seats in coach. My seat wouldn't go back but even if it did, would feel too guilty for person behind to do it - so little legroom on newer planes. They've also cut down on restrooms so for most of the flight there was a line of 5-6 people waiting in the aisle. American Airlines seems to have older planes but at least decent legroom (and I'm not tall - anybody over 5'10 would have to sit at an angle on new United planes!). Been very impressed by Delta's service lately. United feels more like Spirit"

Pros: "Ease of check in with a stream line flow"
Cons: "the TSA check a bit delaying but okay over all"

Cons: "Delayed 5 time and change plane 3 times"

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

Pros: "The staff was really polite and were willig to answer all questions with a smile."
Cons: "The seat I was on could not be reclined. This was most unpleasant because it was an overnight flight. You should earn the clients - even economy passengers - when this seat is the one being assigned to them. I would payed beforehand to get a more comfortable seat if I'd known I was to fly on a no-reclining seat on an overnight flight."

Pros: "Nothing"
Cons: "They delayed the flight due to "operational difficulties". I understand this happens, however, their communication towards customers was unacceptable. They first announced a 20 min delay, followed by another 30 min, then 30 more and then 30 more than then 30 more! They basically kept us at the gate for 2 1/2 hours until the found another plane. For a business like United, and flying out of their hub this is completely unacceptable. We ended up leaving at 11pm for a flight scheduled at 8. They didnt give anything in the plane to make up for it. No food, no free wifi, nothing."

Pros: "The crew was competent"

Pros: "Easy process with no delays"

Pros: "The seat next to me was empty"
Cons: "United put my bags on the next flight to San Jose, so I had to wait an extra 2.5 hours in the airport for the next plane to land in San Jose, Costa Rica while my ride waited for me."

Cons: "The seats were so small, with no space between rows that you couldn't even recline. The tv on the seat in front was so close you couldn't watch it. Miserable flight, and I'm only 5'5"."

Pros: "Terrible"
Cons: "Everything"

Cons: "I felt like tuna in a can."

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

Pros: "The crew was nice."
Cons: "Less leg room than any other airline, complementary food is real bad, they charge you for everything, movies, alcohol and food, in other airlines they do not charge you for none of the above!"
