The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

The second leg of my trip left without me despite being my inbound transfer only a few minutes late. My friends told the gate agent and they closed the doors and left early anyway. Then they tried to rebook me on a flight SIX hours later which only changed when I got a supervisor to make it 4 hours later. The gate agent was nasty, unhelpful, and walked away from me.

They were all very kind, but misinformed. We came from Idaho to Spokane, Washington and were told that my husband and I could get passes to sit with William until his flight took off. (William has special needs.) When we got to the airport we were told only one of us could sit with William, so my husband and I were separated for 2 hours as I sat with William. What is WORSE . . . is I asked for a meet and assist in Portland and they NEVER showed up. NOR did they call me to tell me they hadn't met him. William's grandmother in Portland is disabled and can't walk into find him. Fortunately, some kind citizens helped him to find the meeting point with me on the phone in terror. I have a heart condition, complete with prior heart attack, this type of customer service is UNACCEPTABLE.

Worst part is being squashed in a seat ( I am not fat) and unable To get comfortable

It was alright other than the changes in the Alaska Lounge. That and the migraine I had were disappointing. Other then that everything went well.

Amazing. They work with my disabilities with such kindness, attention, wnd diligence. They make it easy for those of us who need a little more extra care.

Flight delayed due to engine issue. For 3+ hours still not on flight

The flight itself was okay, but there were 2 screaming kids in front of me my entire flight which made it just awful. The parent did zero to try and make the children settle down and flight attendants did nothing either. I understand it's hard to travel with children, but constantly yelling, screaming, or loud talking for 4 hours straight is just ridiculous.

Flight was delayed about 45 min and they never offered an explanation. Peruse, staff were friendly and competent and the flight was safe.

Seattle flight to Walla Walla has a confusing doorway system . Small signs once you leave gate area to tarmac. Almost went the wrong way to my plane.

On time (in fact, early). Easy boarding and getting off.

Boarding process, crew were good. But the seats were so uncomfortable that was all I could focus on. I literally had to sit forward so that all 3 of us could fit in row. I will try to avoid Southwest in the future for any flights over 60 minutes.

1.5 hour delay, poor service, no compassion from the crew. Terrible experience

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

Short flight with plenty of open seats. Drinks and snacks were still provided even on such a short flight. <1 hr

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

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

Our flight was diverted from being a non-stop to getting within 150 miles and requiring another plane. We heard 4 or 5 different versions from SW as to why we had to stop, then wait for a replacement plane. Five hour delay, weather did not come up as a single excuse.... communication was not clear and well explained. No one really took charge!

My flight to Chicago left and landed early. My return flight left two minutes late and arrived 2 minutes late. My seat selections were ideal! There were no snacks going to Chicago and no snacks on the return trip. There are no charging outlets on board.

WiFi on the flight was not working. Thus, entertainment options were limited.

Simply outstanding. Their new lounge for Delta One customers is a cut above the rest.

The Dekta Rep that checked us in was great. She's very personable, pleasant, and can tell she enjoys her job.

The plane was old with small storage areas that had problems closing/latching and not enough storage for everyone, and worn, damaged seats. Service was great but feel a little unsafe on such well used planes.

Terrible and im avoiding them in the future. My initial flight was delayed causing me to rebook my flight and when speaking with the representative to rebook I explained this is the second time my flights were delayed and they did nothing to help me. I wasn't booked to comfort plus or given a voucher or anything. I was almost late for my meeting that I needed to attend on Monday because of the games delta played delaying my flights even more and putting me in the very back of the plane next to an extremely intoxicated passenger

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

Great staff. Wifi is terrible. Signing up for skylines is a painstaking process. Had to call customer service just to get my flight itinerary and confirmation sent to me. Consistent delays. A well staffed company that is run so poorly. Upper management needs to be renewed.

The WiFi didn't seem as fast as it normally is

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

The crew was wonderful and attentive. The seats near exit row were restrictive. Offer healthy snacks please

Delta is a premier airline so my expectations are most always met.

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.

Food choices were very limited. Taste of the dishes was average.

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.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

How badly can you screw up baggage claim? We were told to go to baggage claim too for our bags from this flight. Another flights bags were there. They finished up. More bags from a different flight arrived. Our bags did not Finally the baggage claim belt stopped working and and are flight was still listed on the arrivals for that baggage claim 2. And then nothing It turns out that they had been delivered not only the United baggage claim but far away on a Delta baggage claim No I never told us. It was only the people looking around who had been on the flight But I’m sure there was plenty of time for the employees to raffle through the bags and steal whatever they wanted

Sucks ! All three flights I was on this trip were delayed.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

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

We were delayed Al ost / hours after boarding so that maintenance had to add oil to the engines. Then the oil they grabbed had been left out in the Dallas record cold and was frozen. They had to go back to the hanger and grab some that was not frozen.

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

Flight was empty so had a whole row to myself. Still had to wait to get the bag due to the negligence at Palm Springs departure.

Everything was on time, we arrived early, everything worked well.

Angela was the best fa ever. She made that 8 hour flight a breeze

This was a pleasant, short flight and the crew was friendly.

The service and food needs to improve to catch up with other international flights

Small plane, so no entertainment. Hour delay! Nobody explained wht the delay was all about.

Same problems with delays in Dallas. This was weather related and due to the incoming flight being delayed. This was the flight that was delayed due to a missing flashlight which turned out not to be missing.
