Southwest was greaat! The most expensive but the least upsetting for those we were flying to see.

Boarding was easy. The seats are small and fairly uncomfortable

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

The Southwest experience has definitely taken a dive from its early days. You can no longer deferentiate from other airlines. Air travel is too expensive. Southwest is no longer budget friendly. They have lost me as a loyal customer.

The charges were ridiculous for an hour flight and the turbulence was very scary.

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

The wifi on the plane is great. The only issue that I have is that I prefer an aisle seat and on my trips this week, I was either in the middle or window. If we can work to secure aisle seating, I will be thrilled. Nice trip.

Great flight but super high price. Glad it was a business trip and not personal

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

Business class seats felt very cramped compared to other airlines.

OK, we were delayed and had to de plane and reboard.

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

Complimentary light meal would be appreciated. But great flight crew service on all legs

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

Terrible planning. And even worse gate agents. Absolutely rude behavior.

Flight was scheduled at 11:26am but they keep Delaying until midnight. They waited at airport restless.

Rough flight No beverage service due to turbulence Bottom Seat cushion was non existent

Not good. One of my luggage is missing. And until now they can’t find it

My 9:50AM flight was delayed to 3:40PM "due to incoming aircraft delay". No aircraft is "delayed" that long. Found out once we did board (after several changes in times) that the aircraft had a maintenance issue and we had to wait for another aircraft. Just tell us that. The aircraft we did get was old and the seats need to be updated. I have been traveling for several weeks with AA and you should refresh your entertainment content as frequent flyers have gone through most of your new content. I have Celiac and a shellfish allergy and continue to have struggles with meals on business and first class flights. Please keep this in mind. Sorry - was a long travel day yesterday and a bit cranky this morning with my experience comments. Still an AA fan.

Delay after delay with little communication then AA lost my luggage and at airport would not assist just said scan this QR code to track your luggage and submit a claim. However QR code provided did not work so have to go back to airport

Dloght delayed by 2.5 hrs . Common theme in my last four american floghts

They are rarely on time! Very hard to plan your travels when flights or connections keep getting delayed.

My seat was assigned last row behind restrooms No legroom’s I’m very Pettit Still was not comfortable Food choice was excellent

The flights were on time, the ground crew and on board crews were kind and efficient. The free snacks for Premium+ were good, similar to US First Class snacks. The plane were clean and bright! Complaints? The seats were worn and the seat-back pockets were missing. Overall, I'll book again with Volaris. Ignore the negative social media posts, understand what your fare includes, buy the add ons you need. We had no problems with our personal items and carryons.

Overall a good red eye. Crew chatted very loudly the whole time making it difficult to sleep.

It’s a 2 1/2 hour flight so good and comfort was not my real concern. Safety, easy, fast was what I was looking for. The crews were great, plane was clean, boarding from CBX was fantastic! Definitely traveling this way again.

The money you save flying volaris is not worth it

Is was a good short flight with some turbulence! I would fly Volaris again.

We had boarding passes for the next flight but we could not catch the flight in the small airport just because volaris closed the boarding at the counters an hour before for which we had to sepnd almost 3+ hours to catch next flight. There are hardly anyone who can speak english, but thank God, we have found an young man who could not only speak English but helped us book for the next flight. The air crafts are noisy and scary sometimes to hear that squeeking noises during the take off and during the flight. They do not even offer a cup of coffee for free in flight. The prices are super high and the services are zero. That’s pretty much for this airlines in summary.

Unfortunately it was not a good flight got canceled had to be at the airport all night long to get a different flight to another airport my first flight with Volaris was very bad. Poor services

The boarding , and it would be nice if they would let us know head of time about flight changes

The fly was 2 hours delayed and the plane was old and dirty. A very umcorfotable flight, which I won't recomend to anyone

The flight was delayed by two hours. I had paid for extended leg room. Due to the delay, the plane was different and I didn't end up having extended leg room. I finally was able to reach Volaris on Whats App and they gave me an airline credit. I wanted a refund to the credit card since I hardly ever fly Volaris. Other than that, it was a very comfortable flight.

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

Remind customers of the need to have passport or new ID for boarding.

The flight never took off and we spent 7 hours at the airport

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

This airline sucks. They offer low rates then charge you for everything, the app does not work well, the seats are the most uncomfortable. Maintenance issues on the flight, and you still have to sit through their credit card commercials. People are nice enough but does not make up for overall poor experience.

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

I liked the turn-style feature at gate 209B at LAX. Very efficient process. The gate staff also made several, clearly directed announcements so I felt very informed.
