It was all good, no delays which was a worry. All great

If they actually let me fly. I was rerouted to United and there was no Alaska airlines reps at all. Then the lady who worked the delta counter told me to go away and figure things out myself. Horrible experience.

Pretzels are always a disappointment. Cheezits, Sun Chips, trail mix, anything else would be nice.

I wish my checked suitcase could have been checked since I arrived an hour before take off .

The staff was so kind and friendly! Boarding was efficient and communication was timely. I would seek out flying with Alaska Airlines in the future.

I recently traveled with my service animal, and before boarding, a gate agent kindly arranged for me to have an empty seat next to me to give my dog more space. However, once on board, a male crew member spoke to me in a rude and loud tone, insisting my dog stay on the floor or my lap—even after I explained what the gate agent had approved. His tone and behavior were unprofessional and made me feel uncomfortable in front of other passengers. I understand and respect airline policies, but I would appreciate if this could be reviewed to ensure better awareness and sensitivity toward passengers traveling with service animals. Thank you for your understanding.

It was a pleasant experience. Considering we paid over $3000 for first class there really wasn’t anything special about first class. All the seats looked the same and everyone got the same great customer service. The only thing that was different between first class and couch was the drinks and the meal. We wouldn’t waste that much $ on first class on that plane again.

I received the perfect seat. The cheese tray was delicious. Thank you!

The cabin crew on this team was particularly kind and excellent.

Check in went pretty well and you didn't lose my bag. After I got a drink from the drink cart they charged me for it, and at the crazy overpriced airport rates. Never had that happen before, is that an american thing? what madness.

I truly love flying with Delta. They have always treated me with the upmost respect

Our flight attendant in FIRST CLASS was one of the worst I’ve ever had. She was not at all pleasant, nor particularly good at her service.

Everything went well and was good. Nothing exceptional, but no complaints either. Cheap seats are pretty comfortable.

Staff were friendly and happy. Delta could make sure passengers that don't have the app know of changes. Without Kayak I would not have known about the change of gate or the delay. Kayak was faster to notify me.

They ended up paying for the bag twice, but the counter wouldn't take my baggage receipt. Left it to me to resolve. Not sure how to resolve the issue.

The customer service before board was very rude and when I expressed my concerns about making the connecting flight she laughed and told me I bought the wrong ticket. I explained once it showed the flight was delayed it no longer let me change seats or anything. I was trying to upgrade to make sure I would get to the next gate on time.

Non stop on long haul is the way to go. Great experience

The aircraft interior is old and tired on this aircraft. The entertainment system never worked despite the crews attempt to reset the system.

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Old plane and old configuration/seats but still comfortable for a morning flight

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

Premium Plus is a really good idea for longer flights

7 hours delayed due to operational issues on United’s end. Basically laziness.

Short flight but an "eager to help" crew made the journey more enjoyable!

Flight was delayed only slightly before takeoff due to traffic control. However, the flight arrived early to ORD. Good flight. United has been very reliable for me.

The person I bought the ticket for didn’t make the flight.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

We loved the steward on the plane. He made the night enjoyable

I enjoyed the extra leg room compared to other airlines. The first stewards made my daughter’s birthday special by giving her an extra snack. Then the last one coming home from Chicago to Appleton made our night really enjoyable Thanks for making our trip enjoyable

The flight was smooth, the pilot kept us informed about delays and we arrived more of less on time

Flight delay was communicated before leaving for airport which caused it to be a non-event. Great flight and crew!

Did not get any refreshments. Crew was very nice but limited. Small seats

Wish some foods provided rather than just biscuit/cookie for flight more than 2 hours

Wish a flight with more than 2 hours with some snack rather than just cookie/biscuit.

The flight attendant, a black woman with curly hair who sat near Row 21, was wonderful and kind.

It was good..clean, comfy seat. Friendly warm welcoming crew. Was able to check my cabin luggage at the gate which I was able to pickup in a decent time from baggage claim. The app gave all updates from delays to baggage claim info. Overall smooth flight.

Flight was delayed leaving Dallas. Arrived about 2 hours later than scheduled.

I liked how when I got on board how fast we ended up taking off but what I truly disliked was how uncomfortable the seats were. There was truly never a time that I could ever get comfortable during both of my flights. The seats could get away during shorter flights but flights 3 hour plus makes it hard to enjoy.

The crew was great and the flight was very smooth. Can’t really judge food since I did not get any because it costs money. The seat was comfortable for what we bought. Thanks!

Crew was great. No entertainment and food and beverage was for purchase only, even water

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.

The plane had originated in Las Vegas at 6:30 in the morning and flew to Moline where we boarded. The flight left around 12:30 PM and there were no boxed snacks available and many of the alcoholic beverages were unavailable. I would find it hard to believe that that many of the passengers coming from Las Vegas at 6:30 in the morning, drank and ate that much of the items. I can only come to the conclusion that someone failed to stock the plane for the round-trip. This is a huge revenue failure for the airline and disappointment for the passengers. The flight crew did not seem happy to be there and did not engage with passengers. Allegiant you can do better.

They did not let my husband on the plane with our service animal at the last minute. Do NOT fly this airline with a service animal!

Tight! Seats are not designed for those of us who wear extra-large clothes.

The non-stop flight from Grand Rapids was excellent. I neither expected or needed a budget flight and Allegiant made the trip easy and for an affordable price, Arriving at the Mesa Airport (AZA) is a delight compared to the international airport. For our return flight, we were able to arrive 75 minutes before the flight, return the rental car, check our bag and make it to the gate in plenty of time. That would never happen at most airports.

Easiest flights I’ve ever taken. Plane was comfortable without overly crowded seating.

Terrible. Still have not received the refund from them. They sent it to some account that I don't even know. Spoke with costumer service and they are unable to help.
