As always the crew were super polite and friendly, sadly the weather & a minor mechanical issue reduced the quality of the flight, all’s well as it turned out. Still my favorite airline to fly with

Best flights I e been on. Need gluten free snacks

They removed the cover off my checked bag and threw it away.

late flight, no wifi, no entertainment, no snack. What are you coming to????

They changed our flight to Kalispel and we ended up getting there close to midnight. The return flight got changed as well by a few hours. Then of course some issues with the plane and we were even later. First time flying Alaska, may be my last.

Missoula is a great airport. Desk and gate crews were very helpful and friendly

The flight was delayed out of BIL so many times that I was not able to make my connection. I was rebooked for the next day, losing a full day of my trip. I still have not been compensated as promised.

2 hour delay. Then some luggage was unloaded at 1baggage claim #7 then without notice the baggage claim was changed to #12. No one informed the passengers they were changing baggage claim turnstile. Several of us waited for 90 minutes after the 1st turnstile stopped and changed to other flights luggage.

They changed the flight time from 4:00 to 1:50. We missed the flight because we did not know. We were not entitled to any sort of refund.

The flight ran out of snacks before any was offered to me. Otherwise the flight was good.

My bag was open when I got to Portland and all my clothes were wet and my parking pass was wet

Had to deplane 2 x due to problems with plane. Delayed over 6 hours ans was given a $12 food credit which barely oaud for anything and limited to wear incoukd redeem.

After boarding the plane had to wait an hour at the for the copilot to show up before we could depart

No beverage/snack service without any explanation or reason. Late boarding and delayed flight.

more room in seats, larger snacks, more comms with delays

There was overbooking that delayed boarding. Then an airport emergency lockdown that caused further delays in boarding. However the time was made up during flight and there was a minimal delay in landing. Everything else was excellent.

Delta is the best. It was all very easy and on time.

The cabin and bathroom experience was poor as the cabin and bathroom were dirty and showed signs of an older plane that had not been updated for Customer’s, comfort and health. There was gum on my seat when I arrived and dirt spots around the fan and light controls. The flight was almost entirely full, so there was no way I could be moved from my seat. Th bathroom had the peeling paint.

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.

Fantastic experience once again flying with United! There was great communication from the cockpit and one of the flight attendants went out of her way to get my two little kids some special treats which elevated our travel experience coming home.

1) United economy seats barely recline. 2) I have yet to get United WiFi to work, after numerous flights.

Flight attendants need to know their plane. Seated in first row yesterday. The seat had about a 1 inch recline that was not adjustable. I don't appreciate being awakened to raise a seat that can't go any further forward and such a small recline is either irrelevant or the plane needs to be repaired. Not the way to treat any customer and especially the ones who have paid that level of money for the seats.

The experience was good overall; however, my United Airlines Mileage Plus Account didn't reflect my flights to Houston from Newark. In essence, my mileage rewards points do not reflect my actual travel. This should be corrected.

Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.

Plane arrived an hour before departure. Plane was completely boarded and ready for push back when they decided they needed to change a tire. 1 hour delay on the plane when this could have been done before we got on the plane.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

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 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 amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.

Terrible. We needed to change return flights due to an incoming hurricane. They would not refund our return flight.

The employees at Sioux Falls airport were friendly and helpful. As a veteran/retired military Allegiant allows two checked bags, one carry on bag and a seat on the plane all at no cost. The flight crew and pilots were friendly and very competent.

The check-in and flight crew employees are excellent. The flight was good and the seats were adequate.

The flights to and from Cincinnati were great at being on time for both, departures and arrivals. The planes could use some updating.

It was a dismal experience. The flight was delayed for 4 hours, and we spent hours in the plane, without air, during the summer. We were not provided with water, and the medical assistance was inadequate when it arose.

The landing the pilot was very smooth. The flight attendant was kind of rude.The boarding the plane in punta Gorda was not great made us wait out in the heat 😞

My exit seat was very comfortable Coffee was to be purchased but sodas free 😏

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.

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.
