Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

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

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.

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

All good. Great food and entertainment when there isn’t any on a one hour flight

Flight was delayed twice, I was forced to check my bag, and the only offered water or apple juice on the flight

The flight was delayed for an hour, while we sat in the plane.

The flight was delayed over two and a half hours thus causing me to miss my best friend’s funeral. All because the flight crew had to get more rest. That was the reason stated. I understand however very unfortunate. Glad everyone is well rested and resting in peace.

Flight was late to board, then overweight. I booked a non stop flight for a reason, ended up having to re-fuel in Texas, arrived three hours late.

Quick boarding, efficient and pleasant crew. Wish they worked the mic better in the terminal to be understood more clearly.

Our flight experience started at the check in kiosk. Jennifer  Polete smf 498304 greeted us and assisted us with our tags and check in guidance. She was so pleasant, helpful and friendly. This was the start of my experience with American Airlines and it made such a wonderful impression. The staff on the airplane were also kind, courteous, and attentive. I would definitely fly American Airlines again

All good except both the outbound and return flights were delayed about 1 1/2 hrs.

Not great. My flight was canceled due to a mechanical problem and I could not get rebooked for the same day. I needed to get to my destination yesterday, not today. I was able to book with another airline but it was a layover and ultimately a 1 hour flight took me 12 hours. Normally I like Alaska much more than Southwest, but Southwest came through with a not terrible price for same day.

The flight was canceled so i booked another flight with Delta, so essentially there was absolutely nothing that i enjoyed about my experience with this flight

Non-professional acting crew, Very uncomfortable seats…!! Very bad pricing with all the add-ons for seat choice, luggage fees, etc….soon you’ll charge extra for oxygen. The ticket price means Nothing because in the end, the actual amount i paid, i could have and will in the future continue to fly on a real airline…

With this price, I shouldn't complain on anything. I understand I have to pay for every services they provide. The plane could smell a little better. Advise them to use frebeeze to freshen up the interior a little bit.

Terrible. 1st and last flight on Spirit. Check in process was a nightmare. Despite arriving 1.6 hours before flight we had to be pulled from the ridiculously long line to “self check” our bags which took 10 min and required assistance. Seats are very uncomfortable , don’t move, no pockets, no entertainment, no wifi Basically like taking a time capsule back to the 70s. No thank you.

They kept delaying us and not providing any information which cost us hundreds of dollars . We had an event to get to and missed our even that we had paid for along with lots of wasted time and money booking nee flights.

It’s ridiculous to pay for carry-on luggage. I also wasn’t given an option to specify I have carry on bag at time of ticket purchase. I also could not specify I have carry on luggage at time of online check-in.

The gate area was terrible at San Diego airport -way too crowded in a small space. Since my husband was driving to our destination, we did not have to take any luggage so my kids and I only had backpacks. Therefore everything was easy and smooth. And we didn’t have to pay up charges for everything and it was a short flight. I tried table was broken and it was a little cramped, but it was fine for what we needed. I probably would not fly spirit on a longer flight and if I had to take baggage.

Arrived at 3:45am & found a long line where Spirit employees were standing at the counter but no one was working. Worried if I’d make the flight. Line started moving about 4:15 and got to check my bag at 4:30, realize my flight was at 5:25. Lines thru security were long, got to flight and walked right on. Spirit was cheapest when selected but not after $70/bag and $30/seat - extra $200.

Over 2 hour delay due to “weather” but all other flights were taking off with no issues. We felt lied to the entire time as well.

LA to Seattle was a smooth process. Seattle to LA was delayed more Than 6hrs

Spirit's seating does not work for an overnight flight and my back is killing me. This airline does not meet the minimum standards for being an airline.
