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.

The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

This was a nicer flight - not fully booked and so we were able to spread out.

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.

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

The staff was extremely helpful and friendly at all times! They went above and beyond to get us into an earlier flight in San Diego to make our connection in SFO possible, because our original flight did actually not make it! I did so much appreciate the UA team and how they made this possible. We also didn’t have seats together on the long flight to Singapore, but they found us seats together last moment with no additional cost! Nobody sat next to us, so that we were able to sleep! Thanks to UA for improving their service and Underpricer for booking this trip! Please be careful: 1,5 hrs for transfer in San Francisco might not be enough time in the future

Over 2.5 hour maintenance delay on first morning flight with no acknowledgement, compensation or even gesture of good will. Aircraft had overnighted at airport so issue should have been addressed prior to boarding. Over 3.5 hours before first slow and deliberate beverage service.

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Flight was delayed but more than 90 minutes. This caused me to miss my available windows for pick-up by a friend. I had to pay $125 for an uber back home from the airport which was an added expense that I had not budgeted for my trip. Staff was friendly.

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

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Pilots were fantastic - super smooth. First Class flight attendant was very attentive. Main Cabin flight attendant should try to smooth the rough edges of her voice - very shrill / punitive. Hurt my ears just to listen to her. Recognize they have a (tough) job to do - but tone over speakers needs to be less like scolding a 5 year old.

Delayed and horrible communication and sat on flight for an hour before taking off

Two hours delay, probably one hour because they didn’t bring catering and they had to bring water in board. There a change of aircraft. But delays galore at CLT so it must be a CLT and/or AA operation issue. The 1 hr additional delays because nobody could bring 2 packs of water sooner is probably the best example of this airline operates

It wa sort of on time; the cab was left with some trash

The flight was delayed about an hour for a maintenance specialist to approve the maintenance repair

A very good flight. All personnel were gracious and pleasant. Good flight. No complaints.

American Airlines should be ashamed of their performance on AA1506 on August 14th from DFW to IND. First of all, after we got to the originally assigned gate C7, we were notified with too little notice for a first-flight out situation that the flight would depart from gate A25 in an entirely different terminal -- not just a gate or two away from the original gate. That was the first hiccup that started our day off poorly. It just got worse. Let it be known that the flight crew and gate agents were all as helpful as they could be during all that followed. However, the flight was a horrible mess of an ordeal. The plane was warm and uncomfortable on a hot Dallas morning when we boarded. And apparently we had to get underway for the a/c to be powered up. There was no other explanation for why we had to sit there in the heat. But before we could power up, some paperwork had to be completed, if we heard the announcement clearly enough. Then a "minor" maintenance issue had to be fixed -- but it was enough of an issue that we all had to deplane while it was being fixed, apparently because it was "too warm" on the plane for us to sit there in case the "minor" issue took too long to fix. And after we all finally deplaned and were hanging around the counter for news about when we could reboard, then a flight attendant came up and notified the gate agent that there a passenger at the rear of the plane had caused a major spill of some sort getting up and out of the plane. Turns out that was a bigger and longer delay than whatever the initial mechanical issue caused. According the gate announcements, the mechanical issue had been fixed relatively quickly in due course. But a seat was soaked and had to be cleaned up by a spill. A subsequent announcement then said that the seat belts were affected by the spill and had to cleaned. Then, either the seats or seat belts or both had to be replaced. At each of these announcements, the phrase "we're trying to get maintenance here as soon as we can" kept coming up. Clearly the gate agents were as frustrated as the passengers. After all was said and done, a minor mechanical issue and a major cabin spill issue caused a 3+ hour delay in our flight. American Airlines should be ashamed of its performance on this flight.

Gate check in of luggage was smooth at DCA and luggage came out fast in IND.

only issue is i feel we pulled off from the gate ontime, we sat on the runway longer than i felt made sense.

Flight was delayed by one hour, then another 1/2 hour then cancelled and changed till the next day. We were not allowed to get our luggage & put up in a dirty hotel. I had cockroaches in the bathroom. When I finally arrived home…i noticed the airline had damaged the zipper on my suitcase.

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

The plane was on time. Boarding went fast. Smooth flight and landing. I filled out info for a frontier credit card on the flight from Indy to Orlando and have have heard nothing back. I was supposed to get all these “instant” rewards and have received nothing g.

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.
