Considering my flight to Portland was in a broken chair that I had paid extra for, this one was great. So yeah, wonderful.

Good staff. Comfortable seats. Had to check my bag because the flight was too full.

Crew were bad Didn’t help with luggage When asked for a glass of wine, I was told that they will serve later , which they didn’t to Me and didn’t serve anyone else in First class . Didn’t offer any snacks , Chips or Nuts to anyone . Flight was not crowded either. Worst Service/ or No Service !

Luggage was severely damaged. Flight was late for several hours

The flight was extremely smooth, and so was the landing. Great piloting.

Late leaving so threatened our connection in Vegas to Seattle. We did make up time and made our connection.

I flew Hawaiian Airlines three times during my trip. Each time, when we went to baggage claim, it took about 45 minutes to an hour to receive our luggage.

Flight was delayed several times then eventually cancelled which caused issues with our hotel, car rental and tickets to planned event. We also spent unplanned expense with Lyft to and from the airport which was frustrating. Customer care was not present during whole time at the airport.

I’ve been flying Alaska Airlines for over 30 years & The boarding personnel letting us in the plane were the rudest I’ve ever experienced. Seemed the plane was over booked & they took THEIR mishap out on my son in law… Treated HIM like absolute garbage to the point our family will not fly Alaska after our trips are complete this year. Sad. We loved Alaska until that experience. I hope others never see the same behavior

I only give it a bad rating because I missed my flight

No tv. No free wifi. They need to ipgrade these planes - especially on a 2 hour flight.

First The flight got delayed because one of the crew members was late and we couldn’t board until she arrived. Then we all boarded and got held in the tarmac for another 30 min.

My service light was on 15 minutes before I had to get up and find a glass of ice. And I was in business class. The meals were not for either my wife and I. She did not eat the entire 10 hour flight and I managed a bowl of soup. I was expecting much more from business with what we paid.

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

It was delayed but other than that it was great.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

There was supposed to be a meal served, but there wasn’t and the major toilet was out of order

At first, we were on the runway for about an hour, literally. The Captain did explain that the Control Tower just had a change shift (sounds like an unrealistic excuse) and then that we had to change a runway. A regular economy seat is made for 12 yo twiggy. I understand Delta wants to push for an upgrade, but after sitting in a Comfort seat and in First class. I would say First class is not worthy of my money. The landing was delayed because of the weather in NYC, I don't hold that against Delta, of course. The Captain did alert us to that upon takeoff in Vegas and again as we reached NY.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

It was perfect! I've never flown with United before, but I definitely will in the future

They lost my luggage, so, not happy. The crew was nice but my suitcases never made it, still trying to find out what happened!

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

The flight attendants were great, I joked with one I can’t remember her name, a blond, really sweet. I thought it was run well very professional. This was great i survived Spirit, I know for which I speak.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

First class felt like economy, seats were horrible, food was horrible, staff inattentive

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

Overall all good with the flight. Appreciated the extra spacious upper storage for (vertically standing) carry on. Efficient crew, on time departure... What could it be better is the in seat power. No one was working in our row. We were counting on the in seat power to recharge our battery depleted phones. With the dependency we have in our mobile devices nowadays, the availability of in seat power is a must....

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

Seats were very uncomfortable and being charged for snacks and water.........

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

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.

The worst flying experience ever 3 delays. No accommodations. Had to deboard the plane after being delayed.

I love that I can fly straight to Phoenix/Mesa on Allegiant without any layovers! I bundled my flight to include a couple of different perks, one being I got to pick my seat. I initially picked my seat, and then a week before I flew out, I got a notification I had to pick my seat again, which I did. When I got to the airport, I realized I still didn't have a seat assignment and needed to have the gate agent assign me a seat. What was the purpose of bundling if in the end, I didn't get to pick my seat? Also, bundling didn't include a carry-on so I ended up having to pay $33 extra for that so what would have been a $59 flight ended up being almost $180.

I did not go on my trip. I requested a refund and still have not received it.

I went to lower my tray table and it was very nasty. Looks like some one had left some food on it and then just closed it up.
