Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Flight wasn’t even full, but too many carry-ons caused us to run out of bin space. New bag fee has folks who would usually check their bags carrying on. Watching Southwest morph into Spirit/Frontier is so sad to watch

Flight crew and cabin crew were great. I had to rearrange flights because my original flight was 3hrs delayed for weather, the rub is the flight I moved to boarded on time then we sat at the gate for 2 hours because scheduling stole our first officer for another flight, TWICE. Then our actual FO was an hour delayed. To make it worse my original flight went from a 3 hour delay to departing 15min EARLY. Just poor scheduling operations all around.

Bring back peanuts Take our drink orders when were all seated, especially after you switch to assigned seating.

I’ve always loved Southwest. No issues at all. I was flying standby and the gate agent was extremely friendly and helpful. Boarding was smooth and I was able to get a window seat in the emergency exit row. Crew was fantastic! They were very professional and accommodating. We had to divert from our destination due to weather but the flight crew kept everyone at ease and informed us of all pertinent information. Excellent flight

Plz don't take away free bags and free seating

Very good. Sad to learn Southwest is going start to charge for bags

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Plane late from DC to Austin 30 minutes. Crew made up much of the time enroute to San Diego.

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Overall it was good. I missed my connection but I was put on another flight.

Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

My suitcase was completed destroyed. The top part is broken and unusable now.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

My priority checked bag was not loaded on the flight. I had to sit in baggage claim in Las Vegas for 2 1/2 hours waiting for the next flight. All baggage staff were very helpful, tracking showed it as scanned for loading. Nobody told me why it wasn't on my flight.

All male crew was just too woke for me. I felt like a sardine. I will never take a window seat or the rearmost seat again. I booked early and did not pay for seat selection and that was a mistake. The security at IAH was atrocious. I was violated and radiated as I was in a hurry to connect to my other flight. I may have lost items under the seat in front of me that I couldn't see nor bend over to look.

It’s been awhile since I have traveled on United. I, along with my family who were on the flight noted how smoothly everything went . Boarding, flight crew and service was excellent.

In general ok, my only issue is that they had no hot items for purchase. I had very little time in my connection due to baggage/customs/TSA, thag I barely even had a chance for a stop at the washroom and buy water, to make it to my gate when they started boarding. I had nothing to eat because the trip started early, so I was ready to purchase, and they had nothing except for dry items like snacks. I had to purchase a mediocre, overpriced cheese and fruit board, instead of at least a pizza or sliders that I was planning on getting. Other than that, it was fine. But that’s typical Air Canada, to not have enough.

Terrible. Cancelled my original flight. It made getting a boarding pass difficult. The AA employee (in a loud voice, so everyone around could hear) griped at me for not getting a boarding pass 24 hours before. I asked how I was supposed to do that when I had no idea what flight I was going to be on. She said (loudly), “Talk to AA customer service, not me!” I could certainly tell serving customers was not important to her. Our new flight was set to a completely different city. We had to change our rental car, and the price went way up. It took 2-1/2 hours to get checked in. By then our new flight had left. We ended up on stand by and had to split up the family to get to our destination. It cost us the whole first day of the trip. AA needs to employ people who actually care about doing a good job. I suppose those people are getting harder to find, but atleast try.

Loved the staff, boarding and drink options! Wish the comfort of the seat could have been better nevertheless

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian

At the beginning of the flight there was some turbulence and the announcement was made that there would be no beverage service. The turbulence only last about 5 minutes then it was smooth sailing. I noticed that first class got their service, but the rest of us did not.

Update departure times in a more timely manner. We are not boarding on time if the plane isn’t arriving until after our scheduled departure time.

Update.us on flight information in a more timely manner. Don’t say we are boarding on time ten minutes before the boarding time when the aircraft isn’t arriving for another forty minutes.

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

Took off on time and successfully avoided weather that looked to be a problem along the way

I liked everything. Except that my neck was hurting on the seat. I couldn't sleep.

I was a little disappointed of not having an android charger. Only one it was for an iPhone. I've flown American in the past and had access to one.

It was okay delay was long but I made it

I have never flown Spirit it was much better than anticipated!

Staff was very friendly. They attended to people nicely and reprimanded, in a professional way, to those who wouldn’t listen. AC wasn’t working on the flight waiting to depart in Burbank, so it was uncomfortable for a while since the flight was delayed but then better before take off.

Good on that leg. When I arrived in Detroit I had to wait over an hour for luggage.

The crew was very nice. I would like to see them offer basic refreshments just like a soda and pretzels, etc. for free.

I missed my flight because I was not informed that I had to check in 45 minutes before my flight and I was not allowed to check in any time after that. I was there at boarding time and their customer service was poor and they told me since I didn't check in 45 minutes prior, I couldn't get my boarding pass. I received an email containing my "e ticket" which I Thought was going to get me boarded.But but they said that was just an Itinerary and it was no good to help me get on the plane. I had already missed one flight earlier that afternoon and had to pay for this flight.And then when I missed it they told me it was gonna cost me another $99 to reschedule my flight

Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi

Good experience except for the drunk woman who was with a child. Sad

The flight was canceled and no option was given to get me to my destination even though there were 3 other flights going to Las Vegas later on that night. I will never fly on Spirit Airlines ever again. Terrible service!

I book a filght for me and my daughter from Miami home to Las Vegas and getting her checked in was awful the lady at the baggage check in was horrible!!! She was the rudest person I have ever encountered in my entire life!!!! My daughter dose not speak Spanish and so I was trying to translate for her but the woman would not let me so my daughter was 100 💯 confused because she could not understand what was going on or being said at all horrible absolutely horrible and rude extremely stressful worst experience ever!!!!!!! And then we were actually told by other air port staff not to complain because if we did sprint would make sure we miss our flight ✈️ that they do it all the time 😧

Both legs of the flight were changed. The day of the flight and length of the trip.

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.

Terrible communication with weather delay, lost baggage, near impossible to reach customer service

My tickets got canceled on me by your site and I didn't have a flight. Then you kept sending me emails on the status of q flight I didn't have tickets for.

The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

I missed a flight because of a delay. I had to buy a new ticket through Southwest.

My flight was delayed by two hours which made it so that I would miss my layover flight. I stood in line for customer service for over an hour and when I reached the agent she told me to scan a QR code and it'll give me options. I wasn't offered any help, guidance or compensation, only told that I have options but that I had to figure it all out myself. I was refunded part of the trip and had to buy an expensive same day ticket from another airline in order to get home. I will never fly Frontier again.

We were delayed three times ,and that destroyed my plans, and reservations

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.

Book with frontier airlines with the mentality that they'll cancel your flight, kick you off and lose your luggage. Anything besides that is a win. Compare prices with other airlines (to include luggage) and if frontier is still worth it, book it but know all of their policies.
