6.0 GoodChris, Oct 2026
Friendly crew. Snacks were carb-heavy. Flight was quite delaye
the flight was significantly delayed. Not much was done by the airline to compensate passengers
Boarding now takes twice as long since going with assigned seats.
Not exactly Southwest’s problem, but the new Burbank airport is not great. No restaurants open and tons of work still to be completed. Can’t believe they opened the airport in that condition.
Flight boarded 2.5 hours late (my second southwest flight of the day with late departure), the gate agent was grumpy and unhelpful. Said she was "tired so we aren't going to follow normal boarding order". No complaints about the actual flight crew.
I liked how it boarded fast. I do not like how the seats are just too narrow, and I’m not a big person.
Despite paying for an ‘upgraded’ seat in row 1, I had to put my luggage in the middle of the plane. Snacks were bleh and seat was small and uncomfortable and I am not large. Attendants were fine but not super helpful. Plane just seemed outdated.
Southwest has been a nightmare. Delayed flights, missed connections, systems down. Never again am I flying southwest.
Flight was delayed, full flight and I had to change gates. Southwest flights are always late later in the day.
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.
The back of the plane use to board first after handicap with children and first class. Now the back boards last and there’s a long line waiting to go back while everyone is putting their luggage up and standing in aisle just talking. It’s hard on the elderly. I’m elderly.
Seat didn’t recline at all- very uncomfortable after three hours
The seat on row 11 was a little hard cause my butt was hurting a little bit from sitting after and hour.
The first flight was fine, great crew, but the plane was delayed 45 minutes to go to Seattle because of they were missing a ramp. That would make sense if the plane was actually at the gate. Not if we’re still waiting for a plane. After we landed we waited 30-45 minutes on the tarmac just to get off the plane. Alaska made me miss my connecting flight, wasting my time, and my money. I should honestly be reimbursed, but hey, when does the airline ever actually take accountability? Never.
Wish there were more complimentary drinks available - only had water and apple juice. Also - no snacks were provided during the flight, but we were offered some items as we exited the plane.
My daughter has anxiety and became nauseous after boarding the plane and before take off. She went to the plane bathroom and ended up having to vomit, and your staff promptly removed us from the flight. We explained that it was due to my daughter’s anxiety, and that the condition would not continue in the air, but they removed us anyway. We have flown many many times before on many different airlines and my daughter’s anxiety has resulted in nausea and sickness before takeoff, and every airline has been accommodating and professional. This is was our first time flying with your airline, and also the first time we have ever been removed from a flight. This was the worst service we have ever experienced. This was a special surprise trip we gifted to my daughter for graduating college. I had also paid to upgrade the family to first class and sit all together which we had never done before and can’t afford on a normal basis. Our removal from the flight was not only extremely embarrassing, but devastating for my daughter. My daughter and I were removed from the plane and a call was made by your staff to medical personnel, a few questions were asked of my daughter, and then she was magically cleared. All of this took mere minutes. Why this could not have been performed while we were on the plane, or why this could not have been performed off the plane and then us allowed to reboard is beyond me. My wife and youngest daughter continued on the original flight alone and were very upset and crying due to the situation, yet the staff did nothing to console or assist them. My wife states that upon arrival in Portland and as they were exiting the plane, one of the stewardesses involved said “byyyyeeeee” to them sarcastically and laughed. Myself and my oldest daughter had to wait 4 hours for an alternate flight and were sat in regular seats because our first class seat purchase could not be honored. My wife wasn’t allowed to pick up our rental car and had to wait 4 hours with our luggage until I arrived. The delay prevented us from being able to carry out planned events and ruined the first day of our trip. Upon explaining all of this to your customer service, we received no sympathy, assistance, or compensation other than your staff submitting a request for a reimbursement of my and my daughters first class upgrade cost. When checking in early for our flight back home, the luggage cost for myself and my eldest daughter was no longer discounted as it was for my wife and youngest daughter. Customer service once again could not assist me over the phone and rectify what should have been a minor adjustment. Instead they stated I would have to wait until we physically checked bags in at the airport and then ask staff to adjust the luggage cost. With everything else we had experienced, I was not going to leave that to chance and instead paid full price for the luggage ahead of time. Or experience with Alaska Airlines was a complete disaster and I am baffled at the lack of empathy and assistance from your staff. I’m not sure of what else to say other than the fact that unless we are compensated by Alaska Airlines in some form to offset the horrendous service we received, we will be relaying our experience to family and friends and on social media, and doing all we can to urge everyone to avoid utilizing your services.
I got an email 3 hours before the flight letting me know it got canceled
Boarding was easy and quick. Staff was very friendly. Service of snacks and drinks by staff was outstanding.
It was ok! Not fond of sitting in middle seat. Tried to upgrade with my Atmos card but it was a new account and they weren’t able to look up my account details.
Not bad. Due to not buying a seat, on the way back, my seat was not assigned till 2 hrs before the flight left. Got me worried I wouldn’t have a seat.
New Max 10, first class seats have been shrunk. End of a 20 hour journey, it was United not Lufthansa, just glad to get home
One of my checked luggage was damaged. Cracked on the top by the handle.
I have been flying united for a long time but now I’m done
Delayed - leaving, delayed getting to the gate at destination. What should have been a very easy flight and experience was not.
Better management of the boarding process. Is there any way you could forward all the window seats first? That's the Way Reno Air used to do it, and they had the fastest boarding in the industry!
Wifi is very frustrating - could not connect and therefore unable to work on the trip
Entertainment was great. Seats were good. They did not have my pre-ordered hot food product available but did comp me something cold in place of the item.
Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.
We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.
Seat pitch is horrible especially on the 15 hour flight. Gate crew at SFO was Outstanding. The flight crew was also great.
It was decent, there was no WiFi on the flight but the FA’s gave everyone a warning once we boarded the plane. Unfortunately it didn't give me enough time to download my entertainment content.
American Airlines was horrible! The layover flight to DFW was delayed with no clear communication and for us having to stay the whole day which led to staying a night in Dallas was comped with 2 $12 dollar vouchers and a crappy hotel. We missed a whole day in Tokyo for our honeymoon and stressed the whole 24 hours. We were supposed to leave at the same time the following day, but that was delayed hours again. And instead of letting the delayed flight go first, they let the flight that was scheduled ahead of us. American should refund us the day wasted in Dallas that should have been in Tokyo! We had lost out on paid events that we can’t get refunded. When we finally did leave, it was a good flight. You would think that was the only issue with American but we from the LAX layover, we were delayed 6 hours and were given a $12 dollar voucher that covered a drink only. The only communication we were given then was that because they were delayed in a prior flight we were delayed again. I don’t understand why it was only with American that we had such a bad time with! They have definitely left a sour taste in our mouths for our honeymoon! And then they did send an email saying we could have 2K miles…. For what? To be delayed into another day and miss our flight again?
The delay was not handled well and the offers to move flights and get travel credit was also not ideal.
American was the airline that Starlux contracted for this trip. I arrived in time to make the connecting flight on American, and then the baggage-handler debacle happened. For some reason, the first class and premium economy passengers' luggage was unloaded first. Never seen this happen before. They had handlers removing the bags from the carousel for those passengers. Meanwhile, all of the economy passengers were waiting for their bags, including me. And there were a lot of bags because it was an international flight packed full. While waiting for 45 minutes, my bag didn't show. Meanwhile, an American representative showed up asking if anyone has a connecting flight to Phoenix. Of course I spoke up, and they proceeded to try to find my bag because I had to take a bus to the actual terminal to catch my flight. Which I was not informed of before I arrived. After another 15 minutes of searching, my bag was finally found with the first-class passengers' bags because they had pulled it by mistake. So I rushed to the terminal with the American representative to catch my flight, and they informed me that I missed it and could not get another flight until the next day. Of course, after being on an international flight for 18 hours, I was in no mood to hear this. Now, to be fair, there were a few American employees who tried to help me. After hearing about the missed flight, they got a supervisor to talk to. I expressed my situation to the supervisor, and she was not helpful until I asked for compensation. She agreed to get me a hotel room for the night. So I agreed, and she disappeared into her office, and I waited. And waited. And waited. And waited. While waiting, I was asked by three different employees who knew of my situation if I had been helped. I told them I was waiting for the supervisor to get the hotel room, and they said they would check. Finally, after waiting for 75 minutes, one of the employees who had asked me if I had been helped arrived with my hotel room and arranged a ride to the hotel for me. Never saw the supervisor again. It was now 8 o'clock; I arrived at 5:45! My rebooked fight was scheduled for 6:11 this morning and I have now been informed it has been delayed until 10:00. So am I happy with American? NO I'M NOT!! ;
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.
The flight was on time and arrived early. The crew were friendly and helpful.
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.
Air was off while waiting on the runway and the temperatures became very uncomfortably hot. Flight attendants were very loud and rude the entire flight.
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.
