Flight was good. The food I preordered was not great. The sandwich bread was a little hard, the cheese was wet on half and dry on the other half. There was a lot of condensation inside the package. Other than that it was great.

Flight was good. The food I preordered was not great. The sandwich bread was a little hard, the cheese was wet on half and dry on the other half. There was a lot of condensation inside the package. Other than that it was great.

The plug in for my charger didn’t work and on my return flight back home the passenger in the window seat got up seven times

The boarding was quick, but the cabin was uncomfortable and I got stuck in the galley while the flight attendants handed out drinks after using the lavatory.

Ease of reservations, confirmation. Cramped seating, very, very uncomfortable! Claustrophobic.

Dropping off tagged bags was a nightmare. There was one agent and three baggage crew helping to grab bags. We stood in line for 40 minutes while the agent, presumably, helped customers with other needs (and we were towards the front of the line which was no less than 50-75 people long) before a random guy came up and asked if we could just bring our luggage up to the baggage crew if it was tagged and they said yes to bring it up. The guy told him that ALL these people are simply waiting to drop their tagged bags. Some communication would have been good. All that needed to happen was for one of those baggage people (or the agent) to let the line know if your bags are tagged, simply bring them up to a baggage handler over at the side.

Everything was fine, although I expected to be given a light snack, like other airlines do, but that didn't happen. Nothing at all.

Overall it was a good flight. No issues. Alaska Airlines is always my first choice.

Flight left on time and arrived early. No issues, no problems overall a good flight.

It was all good until they had a mishandling issue with a couple of our bags but overall it was fine and we got the bags eventually

Having a pre-order meal available for the return flight

Over a 3 hour flight. The turbulence was almost imperceptible except for 2 short periods which were not bad and over quickly. The attendants claimed "Safety first" and sat looking at their phones for 3 hours with no drink or snack service. This isn't the first time with Southwest. I thinkit may be there new plan of operation. Oh, and it was June 18, Southwest's Birthday which offered free drinks. NOT.

The flight was okay. The pilots did an amazing job and kept us updated on the flight. The flight attendants were okay. They found time to be chatty with each other rather than focus on the guests. One of the attendants was a little less warm when asking about my bag I had on my lap that I was using during latter part of the mid- flight. Mind you, it was not the departure descent. I’m respectful to each and every attendant, it was the tone in her voice reminding me to place my carryon bag on the floor. I hope to have a better experience next time.

Pretty seamless, just a tad bit late in taking off and landing.

Everything a cheap airline should be at normal airline rates.

Delays delays delays. Late taking off, late landing, wait for a gate, etc.

Multiple delays and gate changes. Arrived at final destination 6 hours late. All rental cars had been taken.

Crew was pleasant; flight was on time. Paid extra for early bird check-in and still got B boarding.

I will be flying again Southwest Airlines. Friendly crew, comfortable and affordable.

Crew was great - friendly and helpful with boarding - letting folks know where overhead space was available thus getting us out of the gate on time.

Captain Scott and FO Brandon were outstanding as was the entire flight attendant crew. I wish they were on every flight!

Not really a “Delta” problem but worth mentioning: Boarding was a difficult process. TSA seemed understaffed and Pre-Check took longer than regular TSA. The supervisor was frazzled and yelled at travelers. Once through TSA, we had to put our carry-ons through another x-ray machine. Then queue up to board with both boarding pass and ID. Then, when we got to the stairs on the tarmac, we had to show our boarding pass again. Maybe this is just normal for Kona since the terminal is outdoors (but still a “secured” area).

Checkin was good, fllight ws good. Onlly complaint is lack of foot on 6 hour flight from Seattle to Boston. Snacks were flimsy - chips and cookies. could have offered something more substantial for such a long flight. I know you can buy food in airport but for the price you pay for a ticket, they should step up for the passengers.

Flight was delayed, we could have been notified earlier and in a consistent manner. App was not refreshing for another passenger to get the latest flight status. We could have stayed and waited at the hotel instead of waiting at the airport had we known the flight was going to delayed for more than 5 hours. The toilet is too tight, and needs to be cleaned more frequently (every hour). The entertainment screen froze, the touch screen not responding to touch. We were upgraded to comfort, it is more comfortable than regular economy seats.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

My flight was cencaled due with the bad weather on Sunday the crew was poorly mistaken my luggage supposed depart with my flight instead I didn’t have my luggage for almost 3 days the website is poorly respond to my complain until I have someone to do it my connection smooth their not even respon or email me even the have my luggage

8 hours late and the plane smelled like urine, that smell in the morning when your child wet the bed in the night.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

This is the first time I've been disappointed with Delta. I was called by Delta to see if I would volunteer to change flights since my original flight home was overbooked. I accepted. The modified booking only provided me a 35 minute layover - when you subtract the fact that boarding closes for a flight 15 minutes early, that gave me 20 minutes to run for one end of the airport to the other. I barely made it. On the 2.5 hour flight to Tampa, the crew repeatedly let us know over the intercom that they cannot serve drinks or snacks due to safety/turbulence. I would have accepted this reason if they did not CONTINUALLY SERVE DRINKS AND COOKED FOOD to First class. If safety is the excuse then the entire plane should be strapped in for safety. On top of this the air conditioning vents were not working correctly and the plane was uncomfortably warm. I love Delta and am a loyal Delta traveler, and I have never had an experience like this. I don't know if there's a disconnect between availability among third-party sites like KAYAK and the airlines or what, but when overbooking causes issues like this for travelers it should be reviewed and changes to the booking process should be made. I blame BOTH KAYAK and Delta for this terrible experience.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

Fine not above and beyond as I had a connection that was delayed due to maintenance

it was so bad. I tried to board my flight from vancouver to saskatoon. And to my surprise they did not board me cause the flight was changed and no email was send to me. and on my boarding pass which i got from seattle says different flight. I did not knew anyone from Vancouver, air canada crew was rude, i asked for today flight but they were rude and i had early morning dental appointment in saskatoon. I was so much in pain and my whole day is wasted today. and i suffered alot. They did provide me hotel but they did not provide me any food. I am really really disappointed first time had so bad experience with air canada. I may think twice to book it again. If i can get any reply or any composition that would be great. Thanks

leg space better than expected. two washrooms for one plane isn't enough.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

Never happened, because of the first delayed flight I lost the connection and had to wait overnight and take two flights to reach my destination.

The flight was delayed, but other than that everything was fine.

Boarding was quick and efficient. My screen didn’t come on and everyone else had theirs working so a little bummer but it was a short flight!

They makes us feel confident on the flight. There was no any cancelation and they are really helpful with us.

Plane was super cold. No entertainment unless you were with mileage program Getting off the plane was super slow

I very rarely fly American and my experience today reenforces that is the correct decision. While the staff were all very courteous, our flight was first thing in the morning so there was no reason to be delayed, yet appropriate maintenance checks weren’t completed prior to our flight so we were delayed multiple times. Not a great showing, American Airlines.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

Flight was delayed because of a bird strike. They had another plane available within 45 minutes.

It was a code share with Alaska - would have been great if I actually made it on the plane, claimed I didn’t have a ticket or a seat even thought I was checked in.

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

i suspect i caught flu on this flight as i could hear someone coughing a few rows back and ended up with flu a few days later. also tiresome to have to watch movies on my device by holding up smartphone screen, would have liked to have in seat display.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

Terrible flight seats where really uncomfortable I had body aches for 2 days and flight was delays almost two hours
