Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

The flight was delayed by 2 hours for “routine maintenance”and because of that I arrived much later iso my Uber ride home was $100 when it’s normally $50.

The airport crew and on board experience was fine. The problem with Alaska air is that there is zero customer service over the phone when you’re trying to buy your ticket or change anything.

Wonderful as always! Pleasant staff, smooth ride, and timely departure.

I enjoyed the feet space in comparison to other airlines. The snacks were also better, great service and the pilot greeted and said hi which made me feel safer.

Well the seats were very tight but the plane was very clean, the attendance great and good entertainment. Maybe they had it, but I wanted a map on the app. Thanks

Representatives both at the gate and on the plane have zero interest in helping you! It’s really unfortunate…

Flight was scheduled to leave at 6a and delayed for 5 hours due to “mechanical” issues. Everyone else on the flight received an email voucher for $24 of food for the delay, except for our group. Also the carry on luggage bins were full and the crew requested that everyone to pass their carry ons back up to the front while everyone was still standing. They gave no other direction and kept rushing the process. After all bags were sent up, they then asked for seat #s to go with each bag… They should have probably had everyone get to their sits and then pass the bags up in a controlled process.

From Las Vegas to Boise all went well. However, our flight was delayed in Boise and I missed my connecting flight from Seattle to Pasco. Moreover, the last flight to Pasco was full and I was booked on the 11:30 flight Sunday and given a hotel accommodation. However, I was scheduled to deliver the Sunday morning service at my church and needed to arrive no later than 10:00. Therefore, I booked a Delta flight scheduled to arrive in Pasco at 23:09. My piece of luggage checked in Las Vegas arrived in Pasco earlier today. I waited at the airport for over an hour last night to speak with an Alaska agent to no avail. I went back after church this morning in search of my piece of luggage and it could not be located. After waiting for 40 minutes to speak to the agent authorized to take my claim, he announced that he was closing the counter to assist on the flight line but not before providing me with a telephone number that would help me with filing my claim. Before I was able to make the call (due to other factors) I received a call from Alaska agent informing me that my luggage had just arrived and I am now waiting for it to be delivered. I deliberately took the more complicated route home to ensure that I would be home in plenty of time to prepare for myself for the Sunday service and accommodate my relatives’ needs. I believe the airport is undermanned given the number of flights coming in and going out. It was fiasco last night with three flights waiting for luggage and another flight landing within minutes. Today’s problems stemmed from a lack of cross training and a serious amount of cargo/baggage going out and too few people scheduled to cover.

In evening be nice to have something sweet rather than dry pretzels

you sent me to some shitty "Airfaireassist" thing that did a bait and switch on the faire. Won't be using Kayak ever again

The crew were exceptionally nice and accommodating. My wife was tired after the flight from Haneda, Tokyo. They let her sleep and served her dinner later after she woke up, before we landed in PDX.

No charging outlets worked. Other than collecting trash attendants didn’t come around. No one could hear flight attendants announcements during the flight. Seat pads were horrible. Sitting on a board for 5 hours. What happened to Hawaiian airlines comfort, hospitality, and extras? Our pilots did an excellent job trying to minimize turbulence and incredible job in landing in windy conditions.

I like that if they asked you to checked in a bag at the gate they give you priority to board

Horrible food and crew. Crew were laughing and talking loud while people were trying to sleep

Yall need to integrate your system with Alaska more efficiently. They booted me off the first flight because of a discrepancy on your end.

The crew at Hawaiian Airlines was fantastic. Kind and hard working. The pilots were great with giving us all the updates to make sure we were informed.

Very good. Nice plane and we sat in economy plus - bigger seats, more room. They served a meal and snacks, and the meal was an apple stuffed pancake that was very good! The snack for us was a hummus sandwich - also very good. The flight attendants were helpful and nice. They have plenty of movies and shows to watch. My only negative -- they changed our flights around and did not adjust the layovers, so we ended up with a very long and unnecessary layover in Honolulu.

I liked the Starlink WiFi but didn't like how they said they were the only airline to offer a free meal and it turns out to be just a standalone sandwich and then charge for snacks to go with it. Rather have the free snacks like Southwest, but have the option to purchase a decent meal for a 5+ hour flight.

Flight scheduled to take off at 5.55pm but it did not take off until 7pm due to some food delivery delay.

Unfortunately, I was put into the middle seat in the first row of premium seating. Sounds nice right? No! that is the worst seat in the plane. I wish I was in economy rather than be in that seat! There is no seat back pocket, no tray table, no charger. Nothing! so unless you're row mates are willing to let you share their basic amenities any flyer should have, you are stuck. It was the worst experience ever! And the flight attendant forgot to take my drink order. I felt like the forgotten flyer.

Superb. Staff great. Great flight. As with other airlines, seating too tight and restrictive.

There is not one likable thing about this airline. It’s starts with the deceptive pricing and continues through the whole flight. The worst staff I’ve ever experienced way over priced bags absolutely no food or drink (unacceptable and you should be embarrassed) the seats are cramped and uncomfortable there is no entertainment there is nothing about this trash airline that constitutes any amount of money. It’s worse than spirit and way more expensive it is disgraceful. Do not travel with Allegiant I repeat do not bother no matter what they say the price is it is never ever going to be the right choice I’m mind blown at how awful the entire experience was I’m embarrassed that I chose so poorly I cannot reiterate enough how beyond horrible this company and its staff are, not one person on this flight or at the airport is qualified to sweep up trash on a city sidewalk they should certainly never be given any job that requires a brain or manners or communication with human beings, what a disgrace to the human race. Your criminal chiselers and should be put out to pasture

Great flight. Friendly staff. Free snacks and drinks would be nice. I would love fewer taxes and fees added on.

My 90 year old father flew with me. He needed wheel chair assistance and is nearly deaf. The staff was amazing with him.

It was fine. Nobody was outstandingly friendly but no one was rude and everything was smooth . The captain thanked us for flying but no one greeted me as I walked on the plane or as I exited which is the least they could do lol

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

Check in on the web portal was cumbersome! After several attempts I finally got the boarding pass.

Excellent flight and even arrived 23 min early. No entertainment , or wi fi on board, but I downloaded a couple of movies beforehand which kept me entertained. Really like flying Allegiant airlines.

WE were delayed about an hour and never any communications from the employees working the gate. We also were moved to a total of three gates.

I love how they show love to their customers and care about them too.

The entire experience was so surprisingly pleasant. And the blocked extra seat between us was such an amazing and nice bonus. Great experience all around and I can’t wait to fly with spirit again!

Horribly late because they had no crew!!! And then jet bridge didn’t work!! Then we arrived at a gate at lax miles away that we had to take a shuttle to a terminal!! I was over 3 hours late to getting the LA! Should have been here at 8:30 and at an appointment at 10:30 and arrived and left lax at 11 am!! Horrible experience!!!

Liked early boarding for disabled customers. Seat comfort could have been better, would have appreciated an empty seat between my wife and I since I suffer from arthritis, neuropathy, and spinal stenosis. Also aisle seat armrest was immobile and this made it difficult to get into and out of my seat during the flight

The airplane had a strange noise that was constant throughout the flight. Thankfully I had noise-cancelling over-ear headphones that muted much of it.

The plane was supposed to leave at 12:59 Amma and another plane took us around 9:30 am. There were 7 delay announcements. We were to receive a voucher of $12 back to pay for food at any place in the airport. One passenger tried to use the voucher was denied. I did not receive the voucher for me, my son, and grandson. I went to the desk and informed them and they took my phone # and email and they told me to wait. I did and was never sent. The plane was uncomfortable, the crew was dismissive of anyone beyond the last two seats. I will NEVER fly or recommend Spirit Airlines again.

I liked that the crew looked well put together. I also liked that there were little turbulences.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

I was never aware that I had to pay $100 per luggage to them on the plane that are simply carry-ons. This is discriminatory and I’m going to be alerting my entire family and friends and my Instagram following up over 75,000 of this issue and misunderstanding, including mismanaging.

Delayed due to no pilot. Per FAA policy I do believe we are to be reimbursed.

The flight was flat out cancelled. Spirit no longer goes to Seattle. I had to rebook my flight. Get a refund from spirit. They also didn’t send me any notification of the cancelled flight.
