Cons: "The plane arrived at 5:38 PM. The first bag was delivered to carousel 10 at 6:08 PM. They were still coming off the belt at 6:13 PM when my bag was delivered. The airline touts its 20 minute baggage delivery guarantee. To claim the guarantee, a person has to find an airline employee. At 6:08 PM, the door to the Alaska baggage claim was locked and no airline employee was in sight."

Cons: "Charging for food is lame."

Cons: "Kicked out of boarding due to nose bleed. Didn't matter that it stopped before the last person boarded. Had to fend for ourselves and find a hotel room at 7pm on a Friday night with zero help from Alaska. The attitude of the agents at boarding was at best apathetic and rude for one in particular."

Pros: "I was moved to an end Seat, as I was in constant leg pain."
Cons: "I was zitting against my Neighbor as the Seats are so narrow."

Cons: "I was placed on an earlier flight as soon as I arrived at the Portland airport. The flight was full, there was no room for my bag in the overhead bins. The bag was checked, not to just Seattle but all the way to Venice. Well, surprise, surprise, the bag was lost on the way to Venice. KLM does not allow enough time in Amsterdam for luggage to make a connecting flight."

Pros: "Movies selection were good, snacks were pretty good"
Cons: "Why make someone pay for an upgraded seat that doesn’t recline? Terrible. Also delayed the flight by an hour, no explanation, and no idea if connections would be made or not. Had to run to my connection and they almost didn’t let me on. Smh"

Pros: "The service was excellent."

Pros: "On time, free beer , good price"
Cons: "No movie, no charging telephone"

Cons: "I will make it my sole purpose to let everyone I know and review this on every site. Kayak messed up our flights so badly and then would not fix them. I spent 4 hours being bounced between airlines and travel sites just to be screwed with for a mistake Kayak made and would not fix. Worst company ever!"

Pros: "Got to fly on the a brand new 737-900 and had plenty of room to fit my laptop so I could work. Friendly crew, didn't feel like a farm animal being herded on to a transport to be taken to slaughter like I do on other airlines."

Cons: "No complaints. I wish that the updates on the flight delay were a little clearer, but that's about it."

Pros: "fast efficient and directions are pretty clear tons of delicious food available at PDX to bring plane was comfortable and roomy"
Cons: "long lines through security"

Pros: "Getting to the correct destination."
Cons: "The fact that the lack of knowledge regarding international travel visas by the counter staff and supervisor meant that two days of the vacation were lost. Upon arrival in China the 144 hour travel visa was granted with no problem within minutes, but the U.S. staff was completely befuddled by the possibility. The interrogation was completely stressful and resulted in a reschedule of the original flight and during the second attempt at flying even an email from the U.S. consulate with a link to the Shanghai/Chinese government immigration site was deemed "not official enough". i will be expecting proper compensation. I was once given an $850 travel voucher for voluntarily giving up my seat, and was flown first class to Hawaii, given 4 star accomodation and then flown first class on to China within 48 hours. This was an involuntary bump from our chosen flight time, all because of a lack of knowledge about current visa regulations and international law on the part of the check in staff. We have been loyal Delta users for over 15 years, and this was the biggest blunder ever. Also humiliating and extremely frustrating, stressful and a big problem with fulfilling our travel plans between son and father."

Pros: "Crew"
Cons: "Seating has gotten WAY too tight. Will not do that again ... discomfort, inability to even stretch a little bit caused painful nerve flare?"

Pros: "I liked the in-flight service and the complimentary snacks and drinks despite the short trip."
Cons: "I did not like that there was not enough room for our 50L Osprey backpacks to be placed under the seats."

Pros: "The crew and the flight were all very pleasant. Highly recommended."
Cons: "Unfortunately the trip was marred by being stuck on the tarmac for the better part of an hour while we waited for out gate. Even when it became available however, we were forced to wait while ATC sent every other plain taxiing through our route which was clearly visible from our vantage point. Not an issue with Delta per se but nonetheless it left us all exhausted and frustrated."

Pros: "Professional and efficient"
Cons: "I am 5'3". My feet never touch the floor, which is quite uncomfortable after about an hour."

Pros: "Kindness and politeness, on time lots of explaining"
Cons: "Beyond seat space all was perfect"

Pros: "Crew was wonderful"
Cons: "Nothing- good flight, I couldn't sleep but that wasn't your fault"

Pros: "No problems curling up against the bulkhead and going to sleep. Crew was very considerate about not broadcasting messages to awaken travelers during this overnight flight."
Cons: "Was a bit warm but in a full plane what can you expect?"

Pros: "Delta has a good business product. The entertainment system was good. The food was good."
Cons: "The business class crew struck me as distracted and putout to be there."

Cons: "Snacks if possible"

Cons: "I chose my seats when I purchased tickets thru Expedia. Then for some reason Delta wouldn't allow me to keep my seats and I had to have them assigned at boarding. Why? What causes this? I was stuck in the back of the small jet from Minneapolis to Cwa when there were a few open seats in the middle. Disappointed. I won't be choosing Delta in the future!"

Pros: "I trusted Delta to take of my clients; Delta usually did. Rather, the employees of Delta did. Now when I travel, I prefer Delta (when they aren't too much more economically). Let me change that to I used to prefer Delta, because the times, they are achanging. My home airport is Atlanta, I'm usually traveling to Seattle or Portland; Delta is king in those routes. There's more flight time options, and the entertainment available is better."
Cons: "Here's where the picky comes in. I downloaded the 'Go Go" wifi app beforehand. When I tried to connect I received a message that it wasn't available on my routes. Why couldn't they tell me that it might not work on my routes before they took my money? Further, why wasn't it available? It's not like I was going on a multi city/country trip, this was Atlanta to Portland non-stop. Then there's the 'Premier Seating". I opted for it on my outbound flight and received TSA Pre Check. I didn't buy the seating coming back; I did not receive TSA Pre Check. Coincidence? My fare was more than Alaska Airlines was offering it for, I paid for the wifi that didn't work, and in order to avoid the back of the plane, you must pay. So, I guess I'll be going to Alaska Airlines. They don't have as many flights, but I don't feel dinged for more money every time I turn around."

Cons: "They should have let us know we would be diverted to Des Moines, and 2 hours Late to BMI before we got to the airport"

Pros: "Quick boarding, on time."
Cons: "The flight attendant checking people’s bags and boarding passes at the gate was not friendly."

Cons: "Two hour delay"

Pros: "Good crew"

Pros: "Cost"
Cons: "OMG, miffed and aggravated right now!! Currently on Allegiant Flight 1355. PIE to CVG A non-eating flight. These POSs MFers decide to have a friggen pizza party in the middle of the flight"

Pros: "Crew nice. Seat okay"
Cons: "Entertainment"

Cons: "Seats, snacks"

Pros: "I like I can pick seats."
Cons: "Ppl putting their carry on in overhead bins nor in their row so when zone 6 (at the front of the plane) gets on, there’s no room in your overhead bin space. Crew should say to passengers to put their luggage in their area, not front of the plane."

Pros: "The crew was fantastic!"
Cons: "I wish there was at least a free beverage."

Pros: "Arrived safely"
Cons: "Almost two hours late."

Cons: "Flight itself was great. Seats are very narrow"

Pros: "On time flight... good stew's, all around pleasant experience."
Cons: "the seats are hard and very narrow."

Cons: "Seats were not comfortable"

Cons: "There was no way for us to add another bag after our seat placement. No one answered the phone for Alligent and the website didn’t work. It costs $20 extra to do this at the airport. Even though it was not our fault that there was no one answering phone calls (and no way to leave a message)"

Pros: "Nice pilot and crew."
Cons: "The warning about alcohol was a bit sarcastic, but I guess in today's world people who have acted out are the real culprits..."

Pros: "Very efficient. You cannot beat the price. All I expected is to get there."
Cons: "The plane was very clean and looked new, the seats were comfortable but did not recline. I missed that."

Pros: "Great crew and online customer service..."
Cons: "1- Flight Behind Schedule 2- Live customer service agents are truly non-existent until 1.5hrs before ‘departure’"

Cons: "I dislike their pricing structure."

Pros: "timeliness of the flight professionalism of the crew immediate attention to a passenger who fainted"
Cons: "passengers were cold and there were no blankets to be offered there were no hot beverages and it was very cold. all beverages were for purchase and yet no complimentary hot coffee nor tea, even if you wanted to pay"

Pros: "The flight attendants, the space on the plane, the prompt departure and arrival!"
Cons: "Media has not been reflective of my great experience."

Pros: "Friendly pilot."
Cons: "My reading light kept flashing off and on. So I couldn't read my book."

Cons: "Bags charge for 105$"

Pros: "Even though the flight was delayed by more than 2 hours, we were able to make it home."
Cons: "Started with constant delays. Flight ended up leaving around 8:30 when the flight was supposed to leave at 5:59. Once boarded there were no snacks, no liquor and only a few options to drink. The flight attendant was mumbling and kept on messing up what he was supposed to say the entire flight."

Pros: "Easy boarding, very nice crew. I would definitely recommend spending the extra for Priority, it is much faster."

Pros: "The pilot landed smooth."
Cons: "We were boarded and waiting on the stuffy hot plane with no air. The seats were so small and tight and then we had to get off the plane and take all of our belongings and waited another 3 hours to get back on the plane after they had told us something was wrong with the plane. It was a horrible experience. And we received nothing for the inconvenience when I had to cancel my work day so I had no compensation and lost clients because of cancelling last minute on them."

Pros: "Great flight. Great staff."

Cons: "So many charges at every step. $5 for boarding passes?"

Cons: "7.5HR DELAY. LOST A DAY. ARRIVING AT 3AM VS 6:30PM TECH ISSUES NOT ALLOWING CHECKIN ONLINE POORLY TRAINED STAFF AND SUPERIORS AT CHECKIN ONE HR ON TARMAC AS PER HEADCOUNT ISSUE WHEREBY, TWICE ASKED ON PLANE WHO I WAS. EMBARASSING. RUINED MY VACA WITH MY HUSBAND SANS KIDS:-(((((("

Cons: "The seating is terrible. Everyone is like sardines packed away."

Pros: "Flight crew were very polite and we received free soda. Free booze however would have been more appropriate after spending my entire New Year’s Day in an airport."
Cons: "Reviewed 9 hours because a crew member didn’t show. Was originally told 6 hours delay only 20 minutes before the flight was due to leave. Received two $8 meal vouchers and rude and slow service from the entire ground crew."

Pros: "Priority check-in and boarding were pleasant."
Cons: "Very tight seats, even for a small person. No recline. Screaming children throughout the cabin."

Pros: "No hassle. No delays."

Pros: "- Good price, even with carry-on and larger seat. - Comfortable seats, despite no incline - better than major airlines."
Cons: "- No food or drinks. - No entertainment. Both are acceptable given the price. - Misinformation regarding flight delay, I was sent notifications and app updated to be 1 hour late. However on arrival, boarding time was as usual."

Pros: "Very cheap ticket Non stop flight to HTS with excellent service. Eat before the flight. It is a short flight but if needed bring your snack... airports near big cities..."

Cons: "Flight was delayed for hours then canceled"

Pros: "Cleanliness, friendliness, on time."
Cons: "Charging for drinks and snacks snacks.."

Cons: "After the horrendous delays getting to my destination I just bit the bullet and bought new tickets (duplicates) on a different airline to get back home-- rather than risk a repeat experience. Ended up costing an extra $300 but at least I didn't have to spend an entire day in an airport trying to keep my 7 year old from losing his mind."

Pros: "They offered a direct flight from Cincinnati to Austin. The price was good, even though they charge for carry on."
Cons: "They land at the Austin airport, kind of. Once we landed they took us to a Remote terminal which required waiting for a bus to fill up and then take you back to the actual airport. There was no quick way for the bus to return and it has to drive for 15 to 20 minutes to get to the main airport. I took 1 complete hour from when I landed to when I got in my car in lot D."

Pros: "The original booking price was great."
Cons: "All of the additional charges for the flight may make other airlines cheaper. You even have to pay extra if you pick a seat before you check in at the airport. If you don't print your ticket online or save it to your phone, you have to pay extra for that too! Overall, the worst part about the flight was that the seats are actually very uncomfortable. I'm not sure if this flight was now worth the original case posted."

Cons: "No issues"

Pros: "I never have any issues. Everything is always great."

Pros: "Smooth boarding"

Pros: "Very good flight crew. Cheerful. Nicely suggested a free adult beverage since we had the Allegiant credit card."

Cons: "Seats a bit flimsy."

Pros: "Everything"
Cons: "Paying for my carry on bag."

Pros: "The outbound leg went well except for the very uncomfortable seats that are thinly padded and do not recline. We left on time and arrived on time."
Cons: "The return trip left five hours late due to a faulty plane. I appreciate not using a plane that was mechanically not working. I also appreciate that we did finally leave on the same day we were to leave. The replacement plane was as uncomfortable as the plane used in the first leg of my round trip."

Cons: "The flight was delayed 8 hours"

Pros: "Excellent flight! Down side no wi fi connection and no Internet, you must buy all food and drink but hey for cost of the trip worth it!"

Cons: "Small seats that don't recline."

Pros: "It was a new plane ...but the same old rules..."
