Arrive 2 hours early, figure out the location of baggage/pass kiosks and gates, minimize all that excess carry-on stuff people seem to lug onto the plane. Also, the airline should do like some did in the old days, board in this order: 1)first class and special attention, 2) then board from the BACK OF THE PLANE TO THE FRONT OF BUSINESS/COACH. Why is this not a thing? Used to be soooo much more efficient, no one in anyone else's way.

At PDX, you can go to either security checkpoint upon entering. Even if the checkpoint with the shorter line is not sided with your concourse, it's all connected & knowing this can save you 30 minutes or more in line.

Alaska, Southwest and Delta are my go-to's. Stay away from independent airlines that can cancel flights without much warning. Also, order tickets at least 2 months out for whichever airline you choose, and avoid third party agents, because they lack the protection you need if flights run into problems.

We usually fly on Southwest, which allows entering and exiting the plane in both the front and the rear of the plane. I was hoping for the same options on Alaska Airlines, but discovered that they do not use that approach at Burbank. I don''t know whether this is specific to Alaska Air, or maybe specific to the fact that it is in a different terminal at Burbank than Southwest uses. Had I known ahead of time that they did not allow deplaning from the rear exit, I would not have chosen seats in the rear of the plane.

The people who find your lost bags will call you, so always label your bags! They also have separate offices. Their service is great too. Just make sure to set up transportation from San Jose when landing if you have somewhere to be. The Uber drivers and Lyft drivers are extremely bad at speaking English, and will often not even take customers who try to engage them, even if you schedule or give them cash. There are shuttles for around the Bay Area, but they can be a pain if you do not have 25$ in cash. I was a little late to San Jose. Alaska lost a free checked bag. I left it on the plane, and then I managed to leave it at the airport after barely catching a shuttle. Well, I caught a ride with two people and a Uber driver. I was going to split fares, right? Well, the Uber driver and I had so much in common and she felt so sorry for me, because I did NOT make it to SFO in time....that she offered to have me stay with her husband and her. I did not want to invade her space at all, so I had her drop me off at SFO. She didn't charge me! Nicest woman I ever met. I ended up staying overnight like she warned in SFO, because the airport doesn't have restaurants or anything that stay open overnight. I was hungry and planning to get something. I didn't get a chance to, because another airline, United, isn't as organized and doesn't care as much. They just told me I missed a flight and the next one I'd have to see if I get onto unless I bought a standby ticket. Which I did. And they told me the Gate changed 4 different times, and made me stay in line for no reason. I just sat in one place for a few hours. One good thing about San Jose is that they do have restaurants, places to sit adjacent to the restaurants, and the different gates, in a very clear layout. There are also clearly posted hours. PDX is very fancy but not very clearly marked in some ways. SFO is an open layout and the gates are clear but there are also points you can't get past. In PDX, you can also rent a car. Both places have large complexes for cars.

Everything was great except for one piece of our luggage was severely damaged and crushed. There were no agents available at baggage claim and the hold time on the phone was over 3 hours. So therefore we were unable to file a complaint. We will be speaking to Alaska Airlines about replacing our luggage when we check in for our return flight.

Great airline. Sat next to a really big person tho

I always choose Alaska when I can. Every thing seems to run more efficiently with them.

I liked that I made it onto the flight rather than “missing” the connection. We left PDX early in the morning along with half of Portland arriving at about the same time as we did- 2 hours prior to our flight leaving. The layover was for less than an hour and we were concerned that we would not make the connection, but as it turns out, the flight leaving LAX was even more delayed in departure due to needing some maintenance repair for the a/c of the plane. As for the food- it seems not so very nice that you are not feeding people and offering complementary alcohol on the international flights any more.

Flight was delayed but still made it to Phoenix on time. Boarding went quickly, the flight was smooth.

The food selections were not good, and entertainment was non existent.

I would have liked if the flight existed. To be fair the federal government canceled it. But, since it WAS canceled, I would have liked it if Alaska Airlines had moved a finger to assist me rather then abandoning me with my luggage, unable to check it, for 14 hours in Portland. So federal regulations forbid them from storing my bag? Then at least help me find storage or SOMETHING.

It was all good, no delays which was a worry. All great

It was a pleasant experience. Considering we paid over $3000 for first class there really wasn’t anything special about first class. All the seats looked the same and everyone got the same great customer service. The only thing that was different between first class and couch was the drinks and the meal. We wouldn’t waste that much $ on first class on that plane again.

This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

Check-in, Boarding and flight were smooth. All the employees and crew was very nice and funny. They gave the kids crayons and workbooks to keep them occupied which was a big win. I’ve flown Southwest many times and that’s the first time I’ve seen that and it is a great addition.

Flight was on time. Wi-fi was a little spotty/slow. Boarding and exit were efficient.

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

They sent a notice that they were boarding an hour early. We had to leave the club and run to the gate. They said sorry, that came from corporate and was a mistake. They did not have enough seating because the flight before it had not taken off on time. They moved our gate and delayed it for an hour.

The boarding and seat assignment system no longer works for me, but I know it is being replaced. Otherwise, I am good with the overall experience.

The lead steward kept singing about "San Francisco" and hotel California---more annoying than humorous....needs work. Flight was smooth and on time.

Still a fan of open seating. Flight was on schedule and arrived on time. The 737 MAX is very comfortable.

Airline travel is always too cramped to really be pleasant, but the cabin crew on this flight did a pretty good job of making up for it by putting on some music during boarding and sprinkling a few funny remarks into the safety briefing and announcements, and just generally being friendly and helpful. It definitely reminded me of why I prefer the in-flight experience on Southwest!

No delays and arrived to destination 30 min early. Staff was super friendly.

San Diego airport is brand new, spacious, airy and very smooth checkin at SW baggage drop.

Did not realize internet screen was hidden between seats and no info printed!!!!

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Very good flight crew and very nice people staff were incredible especially the gate agent

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

The flight was delayed for about 2 hrs. Other than it, it was good.

Advertised fruit trays with cheese, but only snacks handed out!

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

Flight was late - I was downgraded from first class to coach

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

The flight was on time. I generally don’t drink or eat on short flights and the seats were good and the flight attendants were friendly. That’s all I expect

It was nice to have gotten up upgraded to first class with a meal on a three hour flight

United have really come back. Airport and boarding process is clear and good, app and information also very good

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Great flight - friendly and attentive team! Seats in coach were comfy, but a little cramped - but that is the case with all airlines ;)

The boarding by groups is pointless. The first two groups worked fine, but almost Noone boarded in goups three thru five leaving the vast majority boarding when group six was called. It defeated the purpose of spreading out the crowd.

For whatever reason, the flight was not catered -we were told it would be a 45 minute delay waiting for catering - so no food. There were opened candy and peanuts in the seatback pocket. Flight landed early in DFW but due to the assigned gate not being available, we sat on the ground for 30 minutes waiting for the gate to open - making the flight actually arrive at the gate late.

The pilot greased the landing and the crew was fantastic.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

delayed due to weather. Could not communicate with family since the wifi was broken

Experience was good, however I had a delay due to weather happening and had to re purchase a seat on a new plane for a higher price (could be my own issue and misunderstanding) but other than that situation. First time flyer (by myself) was terrific!! The last from ORD to ALO didn't have wifi, but it was only 45 minutes so I'm sure that was part of the reason. Overall my experience was great! Next time I will remember to buy tickets with longer layovers. The delays really saved my overall anxiety. :)

Flight was on time is the only good thing. Person loading the plane called 1-6 to board at the same time, made it chaotic. Plane was too small for even putting backpacks in overhead. Seat for normal sized people were too small. The WIFI didn't work. When we landed had to wait because not enough ground crew.

Did not understand a single word the attendant said on the pa system. I was glad it was not an emergency.
