This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

This flight was a first class choice and left much to be desired. Seat backs on seats were falling apart and torn. Seats actually didn't come to a "full & upright position". Pull out table was sprung. Not any significant leg room. All in all we were on an obviously older plane and felt overcharged for what we received as first class.

Left on time, a bit delayed due to headwinds most of the trip.

Was charged for my luggage despite having been on one ticket from an international flight. Too tired to argue after 15 hours on flight. Was charged for rechecking it at JFK airport. Not sure why those off Kenya Airways were required to do that.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

Not pleasant. We arrived several hours late and my friend and driver were waiting for me a long time at Tucson airport. At first we had to divert to phoenix due to shitty weather. Well, i guess I can’t fault anyone for that. But then when they refueled , they overfueled and we had to wait even longer for the plane to burn off excess fuel. So someone really screwed up there and should get fired. Human error is really inexcusable.

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

Everything was great except for the seat. The backrest would not stay in the upright position.

A220 brakes are grabby and uncomfortable Electric braking is not a good solution for a modern aircraft

Read the fine print. This was my flight home. I booked my flight for the quickest way home. Had a carry-on and a personal item. Same as my outbound flight. Apparently I needed to pre-pay extra for my carry-on. When I checked in, I was told that I had to check it. I said I’ll pay for it, and was told that this wasn’t an option anymore. They said I still had to pay $50 to check my carry-on. I told them I’ll pay whatever to just carry it in as intended. I was not allowed, so eventually I paid $50 to check my carry-on under a plane that was half full, with overhead compartments that were even less full. My white carry-on suitcase was practically destroyed getting from Idaho falls to Denver to Orange County. The low price air fair was a bait and switch. Got me to the gate, made me pay extra, then didn’t even allow me to pay for a carry on. Not to mention that I paid the $8 for WiFi that didn’t work. All to get my suitcase destroyed. I don’t think I’m going to even keep my Untied mileage plus membership and card. Apparently, membership does not have its privileges for this one.

I liked the snacks and the flight attendants were friendly.

Other than a way way too cold cabinets for the entire flight, all was great

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

Absolute disaster. Rude, uncooperative staff. Staff ignores and pretends you don’t exist when you are asking them a question. Erroneous departure gate and baggage claim information. Equipment not working for purchase of drinks. Overly expensive baggage check-in fees. Overly crowded. Dirty airplane. Passengers coughing incessantly as if they were being gassed. Circled airport in flight several times and waited on the tarmac for 1.5 hours. The worst experience ever. Consider another industry. The travel industry is not for you.

The flight was mostly on time, smooth and deplaning was quick. Baggage was really quick at the claim. Comfort was so-so and I paid for economy plus. It was still too crowded and why was a family of 5 scattered all around the plane?

Original plane sidelined. Had to wait an hour for replacement.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The flight experience was very good! Especially the United Club!

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

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

Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.

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

I didn't even take this flight. My plans changed and I couldn't get ahold of customer service and the website kept breaking down during the attempt to change the flight. I wound up taking another airline entirely and eating the cost.

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.

The seats on allegiant airline planes are very basic and don’t have much comfort. After only an hour of flying my butt was hurting a decent amount. But other than that, the crew was definitely entertaining and the flight was very smooth with take off and landing.

We had a 4-hour delay due to a maintenance issue. We boarded, deplaned, then boarded again.

American Airlines is a great dependable airline, on time arrival and departure with polite crew and staff.

Delayed flight due to maintenance and I have had multiple delayed flights due to maintenance in the last month plus

Movies on my phone are great. It would be nice to have a gluten free snack option.

Seat bottom cushions are not good. I’m 165# & they hurt my butt. Plenty of legroom.

The airplane seats were spacious and comfortable, and the flight attendants were friendly and attentive. The food was delicious like never before. The blankets and toiletries were thoughtfully provided. The captain's navigation was steady and reliable. In short, having flown with Starlux, I won't consider any other airline next time.

Like: flights are on time, good boarding process Can improve: planes are old, improve entertainment and make space more comfortable

My flight got delayed a total of five times. And the boarding gate changed four times. most of the time the platform was not up-to-date with the changes taking place. The most discouraging part of the entire trip by far.

Original flight was on time, then late, then changed gates...4 times. Once our newest plane came in, it was fine.

The seats need better cushioning for a nearly 5-hour flight, it was a bit uncomfortable. I'm glad American has free wi-fi but there were was a bout 30 minutes in the middle of the flight when there was no connection which was frustrating.

Flight was delayed due to a steering issue with plane. The delay caused me to miss the connecting flight. The delay caused me to spend an extra 21 hours in airports and flights to get to my destination. The plane issue obviously should have been found and fixed before we even boarded. Ridiculous.
