There was a very drunk man behind me who kept talking loudly to no one in particular. He was slurring his words and at times he didn’t know where we were going or whether or not we landed. He was also loudly using a lot of profanity. The attendants didn’t seem to notice or care and in fact continued to serve him alcohol. He was allowed to purchase 4 little bottles.

We did not realize there wasn't any food apart from a small packet of pretzels - I dropped one and nearly cried.
I recently flew with Alaska Airlines on a trip to Oregon and had a very frustrating experience that I hope the airline can learn from. I purchased upgraded seats with extra legroom for my flight, paying the additional fees for the comfort and space. During my trip planning, I called customer service to inquire about their pet travel policies and conditions, as I was considering bringing my dogs. However, I ultimately decided NOT to bring my pets and never authorized or confirmed any pet travel arrangements. Despite this, Alaska Airlines took it upon themselves to change my seat assignment without any notification or contact. When I arrived for my flight, I discovered that my paid upgrade had been downgraded to a regular seat - presumably because they assumed I would be traveling with pets based on my inquiry call. I hope Alaska Airlines will improve their communication processes and ensure that customer inquiries don’t automatically trigger booking changes without explicit customer authorization. Better staff training on distinguishing between inquiries and actual bookings would prevent this type of situation in the future. While I appreciate that the airline tries to accommodate pet travelers, making assumptions and changes without customer consent is poor service that needs to be addressed.
The customer service personnel were excellent. We had pre-ordered two meals but they could only provide one of them; they substituted the meal with a snack at no charge. Flight was on-time.
At the Portland airport, Alaska Airlines has put in a system where you have to create your own bag tag, then put your own suitcase onto a scale to weigh it. The day we were there, the system was not working properly, and we kept on being told to go onto different lines so it took us approximately 45 minutes to check our bag in. I do not work for the airlines why am I subjected to doing this? How all these companies are shifting their work onto people who have paid good money for their products is crazy. And then the system that the customers are supposed to use don't work properly..
Flight was great. Baggage claim at both ends (SEA and ATL) was atrocious.
Had to sit and wait to get off the plane for closeto a hour. My son also flying to a different destination that day also had like a 2.5 hr delay
TERRIFIC! Thank you all. Jason Robert Kidwell My favorite flight attendants.
I liked Alaska better than other carriers that I have EVER used. Unfortunately, the plane from LAX to Guanacaste leg of my journey had some mechanical problems and had to return to LAX - causing my journey to be very long and added a day to my total trip. The Airline was very prompt in offering their apology and have given me credit to use for my next flight. I thought the terminal in LAX was too cold for comfort, especially if there is a long wait between flights.
Not having to pay 160$ for a 20 lb and 12 lb bag that were clearly under 50 lbs and they overcharged me for them
Southwest's seats are the least comfortable I have ever sat in.
The cabin was quiet for the redeye flight. The area was clean. The staff was great. The 787 Max was in good condition. Drawbacks were that the seat widths were tight for some passengers. The seat padding was at best average and for a long flight uncomfortable.
Southwest like most American domestic airlines, is a mediocre airline. But it is among the cheapest. Oh well.
My flight was delayed 50 minutes and we were rushed to board to then sit for 15 minutes until the pilot arrived. Unacceptable since we could have waited to board. Also the delayed flight was updated AFTER we boarded to more than the 10 minutes as originally stated.
Other than a bit of a delay, everything was good. Again, the boarding process and picking seats is the only thing I don't enjoy.
If we are going to have to pay for luggage, make it easier to do. Put something on the app during check-in so I don't need to do it at the kiosk. I've done it twice recently and I ended up having to pay at the desk because something went wrong at the kiosk in Tampa.
southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.
The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.
Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.
WiFi did not work. For as outrageous as these flights cost, when they’re advertised with certain services/ features they should be in working order
The flight was great! The flight attendants were friendly and attentive. I would definitely fly Hawaiian Aurlines again!
You have to buy the ear buds and they only offers little cup of water twice.
Boarding area in Seattle was super busy and tight due to the layout.
The flight was very smooth and the landing was AMAZING! I have flight anxiety and it didnt peak once! :) Thank you to the pilots and crew!!
Boarding was confusing. Why are families so special that they get to board first? They and their stupid kids take up all the space in the overhead compartments. Then I get stuck having to gate check a bag when I've gone to a lot of trouble to pack efficiently to AVOID checking luggage.
Pillows and blankets were nice since it was an overnight flight, but the seats should be larger and there should be more space between rows so we have more leg room.
service overall good. I thought paying for wi-fi in first class was tacky. Food was soggy.
My flight was unexpectedly rescheduled to three days after the intended departure date about seven hours before the flight, ruining my plans and vacation. Moreover, I was forced to cancel my return flight as well, losing about $400 dollars in the process.
Flight was on time, crew was friendly and prompt with the service. The only thing that could be improved is the seat space, but that's wishful thinking
Cons: Rode a newer Airbus - had the same rattle in the panels above my seat (plastics not secure b/t lighting and panels) as the last Airbus I rode. Cabin was quite warm, borderline hot. Asked to pay for headphones. And the reason I am writing this - when we arrived it took over 20 minutes to get our door open due to nobody on the ground ready for arrival. Likes: Staff was friendly, helpful, and professional. Sandwich was quite good.
Unbelievable check in horrible. Asked to print tickets at the gate after a delay
check in at security was a hassle being scanned. Spirit employees were helpful and professional.
I liked how cheap it was but both my flights were delayed heavily
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
sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
Disaster. They lied every step of the way. We ended up being delayed due to crew and then allegedly abandoned the flight because of a curfew at LGA. No rebooking to LGA at any reasonable time. No hotel. No meal vouchers. Had to sleep in the airport and fly to Newark instead. Will never fly Frontier again.
What I expected, nickeled and dined and a frontier flight attendant loudly complained about her job and lack of communication as she headed to the gate on her cell phone. Not professional.
As every law enforcement agency I could imagine surrounded the plane and we didn’t disembark for 2 hours and then had to stick around for another hour to go get our personal belongings after leaving them behind and being bused away from the plane, it was scary and inconvenient. We were given no information as to why this was happening. Lack of communication with passengers was disappointing.
After boarding and un-boarding twice over 6+hours, the flight was canceled.
Severe turbulence. Captain never came on to reassure passengers after things settled down.
My first flight was delayed 5 hours. The 2nd flight was canceled til the next day and the never even tried to compensate for it. Worse I was delayed again on the flight the rebooked me on.
Boarding in Orlando was not good. Giant mob at the gate, should have been lines.
Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium
baggage clamed had to wait over a hour and half for all people on my flight it was terrible
