Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

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.

The flight was delayed about 20 minutes, but this was an evening flight, so it comes as no surprise. This flight came a good 1.5 days ahead of hurricane Helene which was still far out in the gulf. However, the flight never removed the seated buckle light. The staff announced from the beginning that due to the bad weather (I suppose the hurricane a day and a half away) they would have to do an abbreviated service with water and a snack. I am fine with their water and snack offering, but this was one of the smoothest flights I've had in years. If Southwest believes a flight like this requires everyone to remain seated, then all of their flights should remain buckled for the entire flight. I cannot help but wonder if things like this are a sneaky way to cut back on expenses since the airline is currently under a lot of pressure to reduce costs.

Since the flight wasn’t full, we had some extra room. Crew was great

Although the flight was delayed, but the crew was amazing. They did the best they could to make the time enjoyable.

Tight seats. Be prepared to sit in the middle if you are in boarding group C.

My experience was find with Southwest. The only issue I have is...at the exact time for me to check in...I don't understand how I always end up in C.

The seats are uncomfortable, feels like a small seat pad on plywood.

The seats are uncomfortable and there was no power to recharge a phone.

Flight heavily delayed. No food available despite purchasing an upgrade. No in cabin service.

The woman in seat 1A was allowed to bring a dachshund dog onboard. It smelled terrible and the odor wafted throughout the first class cabin. This was clearly not a service dog and should be prohibited. I paid for the highest class of service, and this was a disservice. Why is Delta allowing this? I may reconsider my future flight choices.

Wifi did not work and they only served water, coffee, or tea.

The plane was very warm upon entering. This was a bigger problem as the weather was cold so people were dressed accordingly.

The crew was very polite as I have a few handicaps and everything was made pleasant. Check-in was easy as I was brought on board by the wheelchair assistant. One flight attendant did make sure my personal item was carefully stored under the seat in front of me. I was made to feel welcome as a customer as I made my first trip with a few disabilities. Entertainment and wifi worked quite well. The only food service were snacks and drinks. Those were okay. Overall it was a very smooth flight and encouraged me to use Delta again.

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

Airline lost my luggage and set me back a day worth of travel due to having to stay in Denver to wait on my luggage

Great - This was the last flight before hurricane closures and did a quick turnaround to get the plane heading north. Much appreciated.

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.

The flight was delayed, but other than that everything was fine.

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Best flight by a pilot I’ve ever been on as a 62 year old

After multiple delays (I lost count), the flight was canceled due to a "maintenance issue". So instead of a direct flight arriving at 5:00, I had to take a flight connecting through Chicago. That flight was also delayed, partially because the plane from the cancelled flight hadnt been removed from the gate and there was nowhere for the other plane to park. (Did nobody think this might be an issue during the hours after that flight was canceled?) The connecting flight out of Chicago was delayed as well. I didn't arrive until 12:30am the next morning. I should have just cancelled the trip. It wasn't worth the hassle and stress.

Delay 14 hours! Missed all connections and had to fly different airline the next day.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.

Terrible. I didn’t fly and I had an important meeting the next day.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

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.
