Airline reviews

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

My original flight was extremely delayed but I was able to join the standby list for an earlier flight. I was grateful for this feature but I wish I could’ve gotten my standby confirmation sooner.

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Forget beverage, they didn't even have water for half the passangers?

Can not wait for seating change to reduce the amount of pre boards - it’s disheartening the abuse. And then then deplaning

The crew was nice. Boarding sucked. Instead of loading from the back to the front people just sat wherever and you had to wait for them to move to get to a seat. And the flight was 25 minutes delayed.

I boarded last because of my boarding assignment and was given a middle seat at the back of the plane. I’m 6”1” so it was really tight. I wish I just had a seat assignment instead of a general boarding group. My bag was way at the front and my seat at the back. Was never offered a beverage and had no room to move.

Friendly crew and super clean cabin. 💺 are comfortable as well. I love the ambient blue lighting.

Cathay Pacific is an excellent, well-maintained airline. While I too would love to fly first, or business class, I did not. I actually had the dreaded middle seat in the middle row, and yet, since I am an inquisitive traveler, I introduced myself to my row mates and had nice chats with both until lights out. Pro tip: Bring a donut travel pillow no matter where your seat is! The flight was smooth, the restrooms clean and the staff courteous and efficient. I gave the comfort level a 4 because of the reasons listed above. The airline meals... let's face it ... it's airplane food but CP does a good job in making it as edible as possible.

I was not able to figure out how to get the entertainment. But the flight was smooth and quick.

The first flight attendant who served refreshments was not pleasant at all. No eye contact, no smile, I used my “please “ and “thank you “ and all but had pretzels thrown at me. Next one far surpassed pleasantries and more like Alaska Air! Good leg room, comfortable seats. Boarding was without flaws. I didn’t order food….

All was good. Flight from STS to Burbank was on a new plane; flight back was on a plane that was showing its age.

Always delayed, inadequate availability of room for baggage but the crew were good & approachable.

Quick, efficient, incredibly kind staff. It was a short flight (50 min)but still received beverage service. Treated my 5 year old like a star. Just endlessly appreciative.

My main complaint is specifically with having booked through kayak. Our flight was delayed and I was no longer able to access my boarding pass through the kayak app. Fortunately I had screen capped it. If I had not it would have been critical problem while boarding.

Lots of turbulence in last 45 minutes, but captain kept us very well informed, which was a big help to a nervous flyer.

I never received a full itinerary of my round trip. I only received the outgoing flight on Sun Country to Baltimore. Throughout my stay in the Baltimore area I kept checking for the information on my return trip to Portland, I didn't receive it in timely manner, so I booked another flight. I received the return flight information on the Alaska flight booked via your sight upon returning to my home in Oregon. The cost of my ticket on Price line was $247.27. The flight was Alaska Airline Flight 9. The confirmation number is YWHLPB. Please be advised I purchased Insurance for this flight. The reference number is UVCV4-X4TK9-INS. I respectfully request a refund for the bookings on, AS 507 and AS 1121.The confirmation number is 72058793562147. Thank you for assistance in correcting this matter.

Only one side of the heafphone jack work. Crew was friendly and helpful.

Great. Flight departed early and arrived early. Deplaning and baggage claim ww were quick.

They separated our seats and moved us to the back of the plane. Hundreds of dollars and thousands of miles used and this was my platinum member experience.

AC barely worked on a 50 minute flight. It was very warm the whole flight. Flight was very bumpy and hard landing.

Got on the plane and then needed to deboard the plane because they didn’t have any pilots?

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

Meh. A late flight meant I missed my connections, and a 2pm LAX arrival turned into gettin in after midnight.

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was no air on the plane and it was very hot.

Good even though flight was delayed, the crew was prompt and efficient.

No access to the Wi-Fi, noisy group of people made it difficult for me to hear through my earbuds. Snacks and drinks - limited service when your seat is at the back of the plane - people up front are always served first and the back gets whatever is left. Not pleased.

In this flight we had selected seating for our family in the middle of the plane in a 2x2 format. The airline changed them to the very back row of the plane and split them to 3x1. Why pay for seats that allow seat selection if the airline will just move them to the worst seats in the plane?

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The plane was delayed ~ 40 minutes. Communication could have been better. The entertainment was poor. We were not offered headsets by the flight attendants. The arm rest pad did not work properly, thus, I could not select what I wanted to watch.

A/C wasn't working. Made the 1.25 hour flight seem like 4 hours! Even at altitude it didn't cool down.

See my previous comments. I was probably booked in business but was moved to economy

No water on the toilets, dirty sits. 4 hours delayed departure.

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

There was nothing to like, flight delayed had to move to different departure areas, disorganized to say the leasr

There were a lot of issues every step of the process. Check in, security, boarding, and dealing with luggage. Plus the money you think you are saving you end up using in hidden fees.

The flight attendant was arguing with a passenger before takeoff. The passenger was frustrated but the flight attendant should have handled it with grace, but instead she was nasty and rude. The seats were comfortable and the flight was uneventful. I wish we didn’t have to pay for drinks or snacks but that’s what you get with a budget airline.

Booked two aisle seats and were switched to an aisle and middle. Not happy.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Gate agent for Frontier in Sioux Falls was horrible. Some people shouldn't have jobs where they need to work with people. This person tried to control everything and even argued with a Sheriff's Deputy. He seemed to write the law and think he was immune to everything and could do whatever he wanted. What a miserable experience for a lot of people. He even delayed the flight just for on his own actions. The pilots made up the time lost, but why does this person have this job. Apparently nobody cares at Frontier. We do, My wife said she would never fly on Frontier again.

Did not realize seats did not recline. Best to travel in an exit row... No question

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

Fecal matter in seat back pocket. Presumably from a kids diaper.
