All good. Great food and entertainment when there isn’t any on a one hour flight
All good. Great food and entertainment when there isn’t any on a one hour flight
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.
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 plane was late arriving. The Alaska people did a great job of turning it around quickly and getting us off. We took off about 35 minutes after it reached the gate.
I liked the flight attendant named Tyler. He was charismatic and genuine. I like the pilot in my second flight, he was considerate to everyone’s feelings. I liked the people I sat beside. I like the plane size. I like Alaska airlines
I appreciate the priority for safety. I did not enjoy how the delays were handled.
orgiginal scheduled flight ( 2.5 hours connection) was cancelled, was given option to rebook between a 1-hour connection or a next day flight. Missed connection flight, and decided to book last minute with an other airline.
Crew members were helpful and responsive. However, the toilet in the only main cabin bathroom didn’t work properly.
Damaged my luggage. Insisted to check in my small luggage now it’s scratched and dented.
It was a perfect flight in all aspects! Both legs!
Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.
Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.
Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.
Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.
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.
Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.
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.
Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍
Compared with other carriers business class for an overnight was not worth the extra expense.
Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)
Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.
AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.
For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.
Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.
Was a pain having to leave the plane and reboard but glad the plane was fixed
It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined
Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.
Worst airline ever! The guy weighing my bag had his foot on the metal plate and when I called him out on it, I got this stupid little smirk. La is a scam and so is Spirit Airlines. All the flight attendants looked like they hated our flight just as much as we did.
Unclear pricing; ended up being charged an extra $52 just to get onboard
Spirit is awful. Too expensive for what you get. Stop nickel and diming.
would be great to get basic water, soda at least and stop charging for carry ons
Your crew is a representation of your Standards and Values. The crew from Seattle to LAX, was very disappointing. The crew was more interested in hanging out at the lobby area. Talking, laughing loudly and eating all the snacks. They did not do regular rounds to see if customers needed anything. This was a huge disappointment. I will no longer be flying with your airlines moving forward.
- flight attendants not very friendly. - Paid for WiFi and plane didn’t have it working , never got a refund.
We got to fly on the new airplane. Much better as it’s roomier and cleaner than before. Most Importantly it’s much more comfortable. I still can’t move the seat back but the extra space made up for it. I didn’t taste the food or drinks because they charge for everything so I didn’t bother. I didn’t experience the entertainment because I downloaded my own movies on my phone. The crew was great. The flight itself was smooth . No complaints.
I was comfortable because I upgraded. I would not have been comfortable in economy. It was a short flight so there was limited food service and no inflight entertainment.
I thought since I upgraded my seat I would get some perks. Free water, free snacks. Free carry on luggage.
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 seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
Everything went as planned. Crew was great. Seats were still not that comfortable.
No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.
I was surprised that all baggage, including carry on, were charged. Each additional bag went up in cost. Really disappointed in the additional costs.
It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.
Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.
I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time
