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.

Was fine, delayed and feels like southwest is always late

The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.

The plane was not very clean. Lots of napkins and kleenex on the floor and in the seat pocket

I liked receiving attention from aged and well experienced flight attendants. I disliked the non-gluten-free snack but I brought my own so I was OK.

Very good flight. Crew was great. No issues and we even arrived early.

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

It was a great flight and the stewards and stewardess were all kind and accommodating!! The seats were comfortable and entertainment screen excellent!

737-800 in first class was pretty dumpy. Seat had an uncomfortable angle, storage under the seat was blocked so even my very modest backpack didn't fit, power outlet was flaky. Weird tiny seat pockets that couldn't hold a gallon ziploc bag, emesis bag missing, etc. etc. No in-flight service due to turbulence. Crew was excellent, boarding was smooth despite a full flight.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Update the cabin with tv screens or at least music sources.

Boarded from a very small gate at LAX. Staff at gate had us line up, then waited 25 minutes to board without a word of explanation. Plane arrived on time then waited 20 minutes for a plane to vacate our gate. Majority of bags arrived after 15 minutes but it took an hour for a small number of remaining bags to be off-loaded despite my “priority” bag tag.

Great staff. Clean plane, but we were delayed for more than an hour due to maintenance issues and had to board another plane.

Lost one piece of luggage even though I checked in 2.5 hours before the flight

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

Service was professional and quick. Premium economy seat was comfortable given the class

Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

In this flight we had selected seating for our family in the middle of the plane in a 2x2 format. The airline changed them to the very back row of the plane and split them to 3x1. Why pay for seats that allow seat selection if the airline will just move them to the worst seats in the plane?

The flight was canceled. Got rebooked to Chicago and when we arrived our luggage where to there. They were going to our original destination the day after. They would not deliver them to our house. We had to go pick them up.

Upgrade planes to have larger overhead bins, especially on this popular route and first class. Easy flight to Chicago, good service in first class. Can't wait for seatback entertainment to be brought back. I like the free wifi and messaging with T-Mobile. Although, the tray tables are not big enough to work even on a small laptop - so why is it called "business" class? Flight attendant said that the flight was too short to even serve water. I've flown that route several times, and that is the first time I ever heard that. No chargers in the seats. Rough landing.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

Good flight, seated and had a water within 5 minutes. Crew was hospitable.

I rated the experience "mediocre" because of the 2 hour delay in take off. This is the 4th flight from DFW on AA where there was a delay and in one of the instances (after 13 delays), the flight was cancelled. I understand weather but for the March 18th flight, there was no weather issue in Dallas or Detroit. I called Concierge Key and they were wonderful, booking me on a later flight in case my flight was cancelled. I have flown with American for many years and never has there been this consistent pattern of delays. Very disappointing.

The flight was on time and arrived early. The crew were friendly and helpful.

My carry on baggage was damaged. Entire trip, I had to carry the baggage. When complained to the boarding crew, they got mad at me and still asked me to valet check in the cabin baggage. Rude boarding crew!!!

Experience was good. We were delayed in leaving by 15 mins because the flight was waiting on a family that was late in getting to the gate. Food and drink options were as expected. I highly recommend checking in ahead of time using the airline’s app so that it’s quicker to get your luggage tags as soon as you arrive at the terminal. No more waiting in long lines!

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

The chair cushions may need an upgrade. I have been noticing they are so worn out, thin so you’d sit in a dip 😄. Other than that, all was an enjoyable trip. Thanks AA!

VERY disappointed at the agent checking in my luggage. I know that the weight limit is 23 kg, a little over 50 pounds (50.71 pounds). Yet the agent kept repeating "50 pounds". So I said, the limit is 23 kg, and she had the audacity to say 'no, it is 22 kg!" Imagine my surprise. Was she ignorant or was she poorly trained? Not sure. The boarding process was pretty good. The speakers were loud enough so I still could hear them despite inconsiderate passengers continuing to speak while the announcements were going on. During the flight, the teenage girl sitting behind me kept pressing her feet to the back of my chair. I turned around several times, yet she did not get the hint. I did not make a fuss since I sense I had a bad streak that night with AA, so I just did the best I can to lean forward and not let that bother me.

It was wonderful upgrading to first. Plane was so cold thou. Crew was great. Wish there was a food option in first for such a long flight. Doesnt matter the time of day. Chintzy.

It was awful everything about it terrible I will never ever ever ride it again

The takeoff was the smoothest I've ever experienced on any airline and this is the first time I've flown on frontier so this was an extremely pleasant surprise!

A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

Long lines, rude staff, everything that's offered you have to pay for.

The last time I flew Frontier was in the 1960s when it was a “real” airline. We flew this time because of the price & schedule. As the saying goes, you get what you pay for.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

Flight was delayed on the runway for 40 minutes the crew did not even offer even water to passengers to compensate for the flight delayed. The flight was delayed due to aircraft mechanical issues. Worst customer service ever

This isna terribly run airlines. If you're one minute late, they will deny your ticket. Don't waste your time or money

Flight was delayed for more than 3 hours, crew at ONT airport was rude, and when we got to DFW the airplane had an issue landing, we had to be taxied to the terminal, and the luggage was hold until the next day.
