No tv, movies for a 6 hour flight! Worst airline I have ever travelled!

boarding was easy and the 737 Max was comfortable and roomy but that was the only good.. there was a child screaming at the top of his lungs for the entire loading, taxiing and part of the flight and no one in the crew said anything or offered any assistance.

Delayed an hour and sat without updates. Ended up an hour late to destination

It was great; it was on time, everything went smoothly, the crew was excellent. It was just uncomfortable for the usual reasons; completely full fight, could barely move because the space was so small. The expected stuff with every airline.

The flight was decent again if there was a place that you could put crying children that would be great. Or maybe make a rule against allowing infants on the plane.

The flight was great. The pilot was great. It was really annoying that the staff had facemasks on. Hard to hear what they’re saying when a mask is covering their mouth. I enjoyed the flight, but there was a crying baby in front of me. You guys should offer flights baby free. I would be very into that me and the person next to me discussed how they should make free flights for all of us that don’t have kids. I wouldn’t mind paying extra to not have to deal with the smell of a dirty diaper or screaming of a child. Also, if they had a separate room, the babies could be sent to the back with a curtain or something muddle the horrible sounds.

Smooth. Courteous. Fun. One problem: the wheels on my checked roller back were broken when I picked up baggage at destination. Must have happened during flight baggage handling but I don’t know where.

Staff very helpful and friendly, in flight entertainment poor. Flight left late and thus arrived 20 minutes late to final destination.

Ground crew was great in Austin, flight crew left a lot to be desired. Not particularly friendly, helpful or nice.

Everything was fine -- on time, clear, clean. I don't want to pay extra for in-flight wi-fi

West Jet has a horrible boarding process and the seats have no cushion.

Everything went smoothly. I didn’t like that when I booked in the main cabin my wife and I weren’t seated together. One would think when booking on an option that allows picking your seat. They would put you and your travel partner together. Had to call to get it sorted. They did fix.

The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

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

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Big plane, long flight, absolutely no leg room and basically non existent air! I am 5”4’ and always travel Main Cabin, I was miserable on this plane and could barely move when we arrived in Cabo due to the cramped leg area!

Flight was delayed 2.5 hours - a big deal on an overnight when you plan to sleep.

I feel like they have upgraded the app since I last flew United and I found it to be super helpful. I had stopped flying United unless absolutely necessary and my experience on this trip indicates they have been working hard to improve their services.

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

All flights were on time and boarding was issue free

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

I like the boarding process, it was fast. The seat doesn’t have a TV for a long flight and food wasn’t served, just snacks.

Use planes with TVs on flights over 4 hours. The free entertainment was a cheap in between solution for a very long flight that you don't even bother providing meals or decent snacks.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. Very comfortable business seats with nice bedding. Good food. We were delayed to let late passengers on the flight, but otherwise great experience.

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

For it to have left on time! Instead of two hours early with zero notice

Flight kept delayed from morning to late afternoon so I had to make other arrangements

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

The crew was not great or professional. It seemed like they didn't really want to be there. A true lack of effort for accommodating customers.

Everything was really good but the seats are not very comfortable.

I paid for WiFi, but it (WiFi) was very very slow, will never take again! Impossible open Utube 😤😤😤

I had no legroom, although I paid for extra legroom. I could barely put my bag in front of my feet and under the seat. The Wi-Fi was horrible. In fact the flight attendant said that they had to reboot it and see if it was going to work and never did.

The guy with severe body odor sat next to me. For the whole duration of the flight it was a torture. The airline should have better policy on limiting people with bad body odor to board the flight. Passengers should not be the ones to endure bad odor for the whole duration of the flight. The airline should be e the one to ensure decent air quality for ever passenger.

Overall it was a miserable experience... I will never fly spirit for more than a 3 hour flight or overnight.
