If there is a computer installed at the back of each seat for music and movies, that will be great.

Better snacks in first class.

This flight had the most beautiful stewardess I have seen in all my travels all over the world.

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

Flight was on time. No problems with luggage. We did have to use our own personal devices to view movies. Unfortunately my ipad did not have ios 13, so I couldn't access movies with it. I had to use my phone instead. Instead of full-sized sodas, I noticed that they gave us a mini-version of soda (around 8 oz). However, they did come through and do a second beverage service during our flight from Virginia to California, so we were able to get more to drink. They did not offer us pretzels during the second beverage service, although they may have if I had asked. Overall a good experience with minor inconveniences.

Very good 👍

Considering I got bumped off of a direct flight and sent to Dallas on American Airlines and had to pay $30 for checking my luggage when if I had not been bumped off of Alaska I as a Alaska Visa card holder would not have had that charge. Would like to know if you will reimburse me this fee. In addition instead of having my direct flight Dulles to Seattle of 51/2 to 6 hrs I spent 10 hours flying to Dallas and then Seattle. Do you think that makes this 82 years old lady happy? No! Sincerely, E Ann Buchanan

Bathrooms were a little dirty and could have been kept up better with all the people using it. They did check our carry on for free since the flight was full and we were checking bags anyways, so that was nice. Pilot was great and the trip was less time than originally anticipated.

I liked the crew. The seats were a bit tight, I did not like that

It was comfortable safe flight.

TSA will always be a nightmare but the agents definitely need working scanners. Sending everyone's baggage through two different scanners three times is unnecessary for them. TSA agents also need to direct people on where they're supposed to stand while waiting for their bags so it keeps the flow of traffic moving. It would also make their lives easier if they were more attentive to the personal affects following the items that are to be scanned. That way they don't encounter irate travelers trying to make their flight through a novel long process along with agents not paying attention to items like wallets and boarding passes getting lost in the shuffle. Best way to mitigate this could perhaps be videos preparing travelers on what to do and expect while they wait in the long lines before going through security. I personally experienced the above happening to other travelers. I avoided all the trouble simply by communicating to the TSA agents and letting them know my property location. But expecting groggy citizens to speak up is like watching paint dry.

A bit crowded, as all planes are these days. I was too tired to stay awake, but would gladly have used a pillow. Couldn't figure out how to recline the seat. For an evening flight like that a more substantial snack would have been appropriate.

In first class, our flight attendant was completely absent! She was playing games on her phone, never offered such basic things such as Estes, and allowed trash and service items to pile up throughout the 6 hour flight.

Everytime I Fly Alaska the Staff are on it to a T, their kind and the flight is so relaxing I fall asleep every time. I just nit a fan of the landing part lol who does. All in All I give them a 100 not a 10 a 100. Thank you Alaska Staff for the Safe travels.

Already 15 minutes late and then horrible experience after landing. Another plane was occupying gate and then mechanical problems with the gate. It really put us behind

It was a great flight. The flight attendants had to keep asking the person in front of me to put their mask up over their mouth and face. I so appreciated this continued effort as aid know if was frustrating for them. Would be nice if adults/passengers, could behave like adults and want to do their part to protect others without it being a hassle. All good though on the flight

Free Wi-Fi would have been better

More food options. The flight attendants aren’t friendly. Customer service lacks once boarded.

They cancelled my flight

Snacks were good and offered on each flight during the trip. I checked my carry-on bag on the final flight, because the flight crew asked for volunteers.

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

Cons: "The seats were too compact, and the water tasted funny. Also IAD is not well equipped for snow."
Pros: "Lots of entertainment options"
Cons: "Need a snack on a six-hour flight. Also, didn't receive drink service until a couple of hours in and was only served about 1/4 cup worth of soda. Disappointing"
Cons: "5 gate changes."
Pros: "On time and the flight crew kept everyone well in formed."

Cons: "Soooo disappointed that you needed to pay for the internet on the smaller planes while on the larger one it was included in the price for us lowly Economy flyers. The flight from SEA to PDX was tight with the smaller seats. My husband is a big man and if he had not been sitting next to me and been a man I did not know it would have been VERY uncomfortable. The flight from PDX to ONT was better with the seats but again we had no way to charge our devices and were asked to pay for the WiFi. Really??? In this day when EVERYONE uses them you are going to punish economy??? If you offer WiFi on the big ALaska planes then it should be offered on all of them. Not sure how hard it would be to wire in charge ports but someone should be working on that."

My dad was sitting in front of me, and when we got off the plane he told me he heard the noises too, and saw some passengers that looked worried who heard the noise as well. My dad works with airplanes, and he said it might have been the panels overhead rattling that was making the noise. Other than that, the flight was okay, but i think the aircraft should be checked out."
Pros: "Good service. Good food options. Reliable flight. Easy check in & quick baggage pick up. Thx."
Cons: "Too much heat on flight."
Cons: "Flight was delayed."

There was no entertainment on this short flight which is OK. There was also no service on this short flight so that explains the rating. The main issues with this flight had nothing to do with Delta. The problems with this flight was ATC and the ground crew at LGA. Before taking off from DCA while we were taxiing, we had to be directed to a parking area for almost one hour because of a ground stop at LGA. Once airborne, the flight was fine. We landed and then had to wait another 15 minutes because although the gate was clear, the alleyway was blocked by other aircraft. We had to wait until those aircraft cleared the alleyway before we could taxi to the gate. It was a good thing that I had a 2 hour layover in LGA because due to the delay, I still had one hour to get to my connecting flight. So I made my flight without difficulty.

The crew was efficient given the circumstances of the flight being delayed by 20 minutes. They asked that the passengers to let those with connecting flights off so they could make their flights which was considerate. They maintained their composures and the flight was smooth overall

This short flight has great views and often has arrived early.

Professional

Flight attendants not very good. We were dealayed and didn't offer snacks. Bottom of the barrel here.

Pros: "I board sky priority or sooner so it always goes well."

Pros: "The flight attendant was fantastic. Very friendly, very helpful, checking on all the passengers. He even loaned his phone charger to one passenger. It was a full flight and he was working hard, but had a smile on his face the entire time. Give him a raise!"
Cons: "the airplane was absolutely freezing. It was so cold, you could actually see the air blowing (like in winter). There's no need for that. Somehow European airlines manage not to freeze out all their passengers. It was less than a two hour flight but felt like an eternity because it was so uncomfortable. Seat size - this is absolutely the smallest it can/should go. I am pretty skinny, but even I'm running out of room and the seat backs could be made a bit more comfortable. Not only is there almost no recline, but the way they are constructed - they actually push my head forward - not made for short people."
Cons: "Food was not good at all."
Pros: "The person at the luggage area, she gave me the ticket, very nice and polite the only professional person."
Cons: "Didn't let me take my hand luggage, small that complies with the size and told me only at gate, I said I had things that could brake and showed no concern and they would send it to my final distinction instead giving it to me in the end of first flight...I've been traveling around the world and the disrespect for customers and poor service of most of US carrier is amazing... some African companies are much better. on the second flight, almost two hours delay, the plane from philly to Lisbon, old, just s few tv screens, exactly like the North Korean airways..., bad food, my tray stayed with me the whole fly, flight attendant not very professional with no concern for customers and job."

Pros: "Overall the flight was good, on time"
Cons: "Nothing at this stage"

Pros: "Food, OK legroom, complimentary wine & beer on a US carrier"
Cons: "Barely functioning ancient touchscreen system"
Cons: "They had no record of this portion of my trip, after a few people checked they found the Chicago to Ammon part so they added me onto a flight from Washington to Chicago. All should of went well from there but they sent me to the wrong gate. Luckily I just made it to the correct gate for boarding. Upon arriving at Chicago there was no one available to provide information on how to get to Royal Jordanian gates. Also on my AA portion of my flight coming into The U S in New York the flight was cancelled and I was told the next flight Available was next day (18hr delay) at the other NY airport. I had to have someone drive from D.C. (My destination) to pick me up"
Pros: "Crew was nice"
Cons: "Food was poor"
Cons: "Flight was delayed two hours then canceled."
Cons: "Allowed me to take earlier flight"
Cons: "Haven't taken it yet!"
Pros: "The plane has improved greatly with their comfort and leg space"
Cons: "With checking my luggage my bag fee was waived a total of seven times this trip because I'm a military wife to see my husband overseas who is serving a year in Saudi Arabi except this past time on October 2nd at DCA airport. Spoke with the Supervisor Ralph who stated it was against policy. How stringent is this policy if it was waived seven times previously? Policy needs to be reviewed with entire staff. I will no longer use American Airlines because their military convenience and policies no longer seem to favor the military. My husband also after speaking with him will also no longer use your airline including all his members he overseas when they return after their year tour."

Pros: "The flight was on timely"
Cons: "The staff was very informative"
Pros: "Great customer service and attention"
Cons: "No inflight entertainment"
Cons: "Having to check my carry on bag. Brought only a carry on to avoid baggage claim, but was forced to check it anyway. There is NO organization to the boarding process, so in the free-for-all at boarding, people in any boarding group are let through with WAY MORE than 1 carry on and 1 personal item, leaving no room for my bag and I was in group 2 (not sure how many groups there are). Horrible disorganization at boarding. Board from back to front for goodness sake...its common sense."
Pros: "Crew was ok, did their best considering the circumstances, but even they were getting aggravated and were short with the passengers near the end."
Cons: "The Washington airport is horrible. The gate we left from was not a gate but a series of doors that buses came to. This wouldn't be so bad if they were able to handle it in an orderly way, but the airport showed complete incompetence in organizing anything and there were people everywhere trying to find the right door which kept changing on them, and the times kept changing...it was a mess. Then, when we finally got on the plane and were about to take off, the air traffic control tower called and said that their flight path was incorrect and to not take off...but didn't give them a new flight path for nearly two hours as we sat on the runway. Nationalize the airports in DC, fire the whole lot and start fresh, I'd say."
Pros: "Everyone was amazing. Helpful. Kind professional"
Pros: "The lady sitting next to me was nice to talk to - that's about it"
Cons: "The whole experience was terrible. The airport gate terminal was chaotic. While boarding, I am told I have to check my bag because apparently the flight was overbooked and there was no room for my carryon. We finally get on the plane and are told by the pilot that we have to stop for fuel - MID FLIGHT!!! I have never had a pilot stop to fuel up in the middle of a flight. And he told us it would take 10 minutes. It took an hour and a half!!!!!!!It completely derailed my connection flight. I missed it and was rescheduled, but wasn't told anything. I get to my new connection flight - that wasn't leaving for another 2 hours mind you - and ask the lady about my bag, because I was nervous it wouldn't get there with the flight change. Her response - "Well, they knew where you were going, right?""

Delays all the time!!!

Frontier staff is outrageous and rude!

Had to pay $99 at the gate for a laptop bag I had flown with on Frontier at least a dozen times previously with no problem

I did not like the way they do I usually travel with my carry on bags But frontier did not allowed me to travel with it And they cleark are not friendly sometimes They pissed me off

Frontier cancelled it without any explanation…and no support..

Frontier Airlines got me to where I needed to be with no extra services that I didn’t pay for. They even got me there a full hour early.

It was very cold on the flight and where I landed.

Great price! Clean and efficient.

Uncomfortable seats

I caught the COVID19 virus. Had to cancel. Frontier charged an $80 cancellation fee per ticket. Could not have been worse! Everywhere else I have flown in the last 30 days (even with non-refundable tickets) gave a full change or voucher. HD8IPQ is my reference code.

The only thing I liked was the care of the flight crew. One of us is a disabled passenger and they didn't give special consideration for someone who is disabled and couldn't walk to the gate nor to the seat. Our seats were in the REAR of the plane. That's no place for a disabled person. Not even a window seat. Lack of communication to the special service assistants for a request of an aisle wheelchair to get to the seat. The flight was delayed and we were sitting in the plane for over an hour to wait to exit the plane. We were informed there was lack of staff at Orlando International Airport for Frontier Airlines, and we had to wait for other staff to come from another gate to get us off the plane and get bags to baggage claim. We were waiting in Baggage Claim to retrieve our bags for over 30 minutes.

Too many announcements. There was no food or entertainment but there was no n/a option

Pros: "We missed the flight due to parking difficulty We came to the airport at 1:10 pm and flight supposed to leave to Ontario at 1:30 pm I requested a flight change or refund But neither refused Please help us to get refund or credit for the next flight Sudath Edirisuriya 916-751-8219"
Cons: "Please provide help to us"
Pros: "Nothing."
Cons: "Social distancing guidelines should be applied on plane. Rather than leave 20+ seats empty, and cram everyone 6 to a row. Flight was over 2 hours delayed due to not having maintenance staff available. And then I was crammed in next to an oversized individual where we couldn’t even keep the armrest down."
Pros: "The flight, crew, etc. were great."
Cons: "I would have liked to get coffee or soda for no charge."
Pros: "The legroom we paid for."
Cons: "This time the attendant still wouldn’t let anyone in rows 2 & 3 place the carry on they had paid extra for in the overhead bins, but she didn’t make me put it under the seat in front of me (this losing the extra leg room we paid for), so I put it in a bin behind me. The plane was late, but the pilot made up most of the time, but then it took 55 minutes to get our luggage."
Pros: "The overall flight and crew was great no complaints"
Cons: "Your purse shouldn’t be considered a carryon unless it’s larger then the average personal carryon and one complimentary beverage and snack on flights over 2 hours"
Pros: "Nothing"
Cons: "Terribly uncomfortable seats"
Pros: "The crew was great. In a good mood and accommodated my requests. (For complimentary water and a trading card to remember my trip)"
Cons: "Seat was awfully uncomfortable. I’m only a slim built 5’9” woman and my knees were indenting the next seatback. And the aisle was too busy for me but that could have been fixed with paying for a window. I do not recommend flying in these economy seats for any longer than 2.5 hours."
Pros: "I got back on time and smooth flight!"
Cons: "Recliner sitting"
Cons: "Very nice. Smooth. Fast"
Pros: "Yes"
Cons: "Thanks , perfect , not a thing"
Pros: "Good service"
Cons: "Entertainment and better seats"
Cons: "Entertainment on long flight"
Pros: "Overall a quick flight crew was great always picking up trash it was clean."
Cons: "Only thing I hate and probably will never fly frontier again checking my bag was 50$ and the seats are absolutely uncomfortable I will pay a little more and fly with someone else everytime I fly because after bags it’s not worth it"
Pros: "I like that the plane was on time departure from Ontario in arrival and also on departure from Orlando to Ontario"
Cons: "Some type of entertainment on the plane"
Cons: "Nothing . Nothing at all . Considering I didn’t have to drive, ride a bus , or train . And can get from one side of the country to the other in the time it takes me to get half way through a work day. I’d say any small inconvenience is still well worth the price. And hats off for the TSA . Well done"
Pros: "Price was great"
Cons: "overall expirence"
Pros: "On time, clean."
Pros: "n/a"
Cons: "n/a"
Pros: "Inexpensive fare. CLEAR and TSA-PreCheck for security screening a big help at very busy Denver airport."
Cons: "Bag check is expensive at $40/per. Nickel and dime passengers for everything. Fare was cheap so I guess it was worth it. Online check-in was a big pain, since Frontier had incorrect/missing information (name-was that Kayak's fault or Frontier? I don't know.). When I attempted to correct it, they changed my fare to full price. Allowed check-in to timeout and eventually successfully completed without corrections so that fare was unchanged."
Pros: "Boarding in zone one"
Cons: "2nd most hated airline behind Spirit - they charge extra for EVERYTHING!!! Seats are hard & don’t reclibe unless you pay $20 more. Will NEVER fly them again!!!!"
Pros: "None of the self check in stations was working so there’s one very long line to check in with attendants. No effort by staff to get passengers with current flights to get to front of line. Had to convince staff that small women’s pack was a purse and not a 2nd bag to be checked in for $50. Woman in front of me had a more traditional large purse and encountered no problems."
Pros: "Nothing very disappointed with Frontiers service"
Cons: "From Ontario to Austin we were charge $50 for each carry on luggage we 1 for me 1 for my husband total $100 charge From Austin to Ontario carry on luggage was free why?Im filling complained about the airline"
Pros: "The roomy seats"
Cons: "No tv in headrest and flight attendants were not very friendly"
Pros: "Flight to SAN was 3 hrs delayed..."
Cons: "Flight delayed 2 hours! Seats don’t recline in coach!!"
Pros: "Fast and friendly"
Cons: "Should offer free water at least on 3hr flights"
Cons: "We arrived very late due to the airline being run so poorly. Something about paperwork according to the pilot. Now the rental car company is closed so I have to sleep at the airport and wait till the budget opens again in the morning. Frontier should put me up in a hotel as their mismanagement caused the delay not the weather. But they just said too bad because the flight was less than 4hours late. Frontier - never again!!!- plus the seats are painful"
Pros: "Clean smooth flight and nice crew"
Cons: "Rude woman at check in counter"
Cons: "You have to pay for the carry on and seats."
Pros: "Nothing"
Cons: "Everything"
Cons: "The plane was over an hour late and they lost our luggage. I understand things happen it was not that big of deal but the lady in Syracuse was unfriendly and acted like she could care less. We ended up going to a wedding in our shorts and flip flops because we had no clothes and not enough time to purchase any. Our bag was delivered about 1am. The customer service was really pathetic. Not even an I'm sorry this happened."
Pros: "a bit better, the flight was only half full so it made the experience more enjoyable overall."
Cons: "Kinda annoying they are always trying to upsell."
Pros: "Nothing was 2 hrs late"
Cons: "Was 2 hrs late"
Pros: "The flight itself was fine"
Cons: "I used to love frontier but now everything from baggage policies to checking in feel like a huge hassle"
Pros: "The fair was low and boarding was efficient."
Cons: "The booking process was terrible online. There’s a charge for refreshments, the tray table is tiny, the staff didn’t seem happy, the seats don’t recline at all, they charge for carry ons, no outlet to charge my device."
Pros: "crew"
Cons: "you should be arrested for those seats"
Pros: "The fabulous front row seats!"
