The Southwest airline was ok. A big thank you to Kayak team (David), who worked with me on Sunday afternoon to rebook my travel from Burbank, CA, to CVG. My original flight on Sunday was delayed, so I had to cancel Sunday flight and rebook my travel to Monday. Could not have done it without help from David from Kayak team. Ante Soda GE Aerospace

Seated at front bulkhead for a smidge extra leg room away from home and on flight back home. Away crew was very proactive about assuring our carryons had space close behind us (because no seat in front of us our personal items had to be in a small bin overhead). They actively required passengers place overhead luggage on its side so more items could fit in bins. Home crew made no such efforts. I had to struggle back rows to get overhead bags upon landing, no crew help then either, and some disgruntled passengers as I and others retrieved our bags. There was a system that worked pretty well. The home bound crew just didn't feel like working.

Red eye from San Diego. Temperature of the cabin was way too warm and the air duct flowed very little air.

Overall good, just screaming kids in the area the whole flight.

I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.

The crew canceled the complementary snack and drink in anticipation of turbulence that never materialized. I was counting on the drink (water) to take the the doses of medication - prescribed for my heart condition - that were due during the flight. Since no snack or meal was served on this flight, I cannot rate the food quality. Otherwise, this flight was excellent.

Really full flight, checked in ASAP and still mid Cs.

On time and stellar premium class service. Not liking non LCD display in seat backs - miss the convenience of not using your own device.

It was my first time flying with Alaska Airlines and it was a pleasure!

Plane had mechanical issues. We had to de plane and board a different plane and were an hour late

More space for economy, and the bathroom size is only for people with size XS

We enjoy the professionalism and cleanliness of the staff and aircraft. We are grateful to the experiences pilots and flight crew

Our experience with American Airlines was extremely disappointing and honestly made an already exhausting international journey much worse. After flying all the way from Melbourne and dealing with significant jet lag, the American Airlines experience at LAX was the last thing we needed. The terminal and boarding area felt very old and uncomfortable, with little to no air conditioning and only old fans running in the area. Boarding was also through outdoor stairs rather than a jet bridge, which felt especially inconvenient after such a long journey. Even though we were traveling First Class, the onboard experience was surprisingly poor. There were no meaningful snack options, no decent coffee available to order, and the aircraft was so small that there was barely enough overhead space for carry-on luggage. The staff experience was also disappointing and lacked the warmth or attentiveness we had experienced on our international flights. To make matters worse, the flight departed late, extending an already very long travel day. Overall, the combination of the outdated terminal, uncomfortable boarding process, limited First Class service, small aircraft, poor staff experience, and delay made this an extremely unpleasant final leg of our journey. It significantly worsened our exhaustion and jet lag rather than making the connection home easier. Unfortunately, this experience was bad enough that I do not plan to travel with American Airlines again in the future.

I was so hungry. No meals. Staff very nice. Seat arms armed too tight and didn’t go up. I was scheduled for First class, but was put on Standby, even though I made my reservation a while ago. Thank you.

Gate 461 the worst in LAX Boarding lacks professionalism And as usual, your food sucks.

Flight attendant made the flight very enjoyable. He was courteous and gave great care to the passengers

My seat had a worn out cushion, which made it a bit uncomfortable. Other than that, the flight was excellent.
