That was my first time flying Milwaukee to Seattle & vice versa. I think we choose a good airline. Seattle’s traffic & airport is busier than Milwaukee so get there at least 2 hours early. Download & keep an eye on the Alaska airline app for flight info updates.

Make sure there's enough time between connections to go through customs and recheck your luggage. They will not let you proceed so you can't even try to run and catch the flight if you want to.

Boarded on time but once we were ready for take off, the crew determined that, although every seat was taken, somehow someone was on the wrong flight. Delay, delay delay, announcements and ended up with one person checking EVERY ID against their passenger Manifest only to figure out it was a "clerical error." We departed 54 minutes late causing me to run in the St. Louis Airport to make my connection and lose the priority boarding spot I had paid for. Unnecessary delay.

I was re-booked onto another flight because my original flight was delayed and I would have missed my connector. I ended up in the “C” group after paying extra to be in the “A “ group on the original flight. At least if you’re going to re-book people, re-book them into the same group.

Flight was delayed due to plane not passing inspection And one of the crew had to time out and we had to wait for another one A 3 hour delay

mandatory demand customer to check their carry on because not enough people check bags.

Connecting flight is on time and boarding was a breeze!

Excellent. Would encourage Southwest to keep current boarding procedures with free style seating. Makes for a fantastic experience

As always, the entire Southwest experience was perfect. Purchasing the tickets on the Southwest web site was effortless, departure and arrival gates were spotless and comfortable, plane was clean and comfortable, crew was excellent and flight was on time. Wheelchair service in Las Vegas at departure was somewhat chaotic and disjointed, but I am not sure if that was Southwest problem, airport problem or combination.

I wish they had movie screens in the headrests. The seats are much improved, more legroom and recently renovated. Bathroom was clean. Staff was outstanding!!

As always, the entire Southwest experience was wonderful, from online booking to flight to baggage retrieval. Very grateful.

The weather could have been better. There was a 40 minute ATC delay in SFO because of marine fog and a micro cell storm delayed landing and take-off at Nashville. The gate was changed 5 minutes from boarding from gate B3 to gate C23 at Nashville airport.

They changed planes and the new plane couldn’t carry enough fuel to fly across the country so we had to stop in Kansas City to refuel. Flight was delayed .

Flight was too crowded and seats are too small, especially since passengrs are getting larger. Having a middle seat is ALWAYS tough! Woman on my left was large & kept creeping in to my space. Flight personnel were great! Have more savory rather than sweet snacks please.

Flight was crowded and the woman sitting on my left was large & kept crouching in to my space. You need bigger seats or smaller passengers to fit into the seats you DO have! Snack were OK. Would appreciate if airlines had more savory rather than sweet snacks, thank you!

Delayed flight (1hour) plus a long layover after an overnight flight with no backup plane available.

We were delayed, which I think had to do with air traffic control. Otherwise, everything was great.

The boarding process needs to be refined. Sometimes the gate crew calls out the zones and then flip to showing the.zones boarding on the gate monitor display. So, unless you are huddled around the gate lanes watching the monitor, you could miss your boarding zone. Suggest the zones be announced each time a new zone is allowed to board.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

On time flight. Seat comfort could be better in the Comfort section.

My issue was with TSA agents for delta airlines. My luggage got flagged. The agent was going thru another persons first. He took 20 min to go thru hers. I asked them to bring mine closer so I could sit down . They said you can go sit it will be fine. I said I am supposed to keep my eyes on my bags at all times. The agent was meticulously unwrapping 2 gifts that the lady had and then tried to re warp it. He was trying to be kind i get it but 20 min for me to stand watching him do that was ridiculous. It was 6 am and there were a ton of travelers. Mine was flagged for some air packed tea that I bought in Turkey. My previous delta flight and 2 others before didn’t flag it. Consistency would be nice. Also on the flight the window shades were down for take off and landing - I thought that was very odd I thought they had to remain open for take off and landing.

The flight was an hour and a half late departing which was inconvenient

During booking, I kept trying submitting my payment from the Mexican website and it didn't work. After I had the idea to change it to the Canadian website, it worked but I had to be charged the equivalent of 50 CAD more. I received the clear instruction that I would only be able to check-in at the airport and that it was impossible to select a seat 24 hours before departure, that I had to pay 144 CAD to do so, although not only was I able to check-in 24 hours before departure, but I could have selected my seats for free then. All in all, I almost threw $200 out the window due to misleading information. Besides, the app kept crashing, the information to get to the gate on the app was inaccurate, my gate was switched and I was only informed once in the air (luckily I had noticed the departure pannel), I was not addressed in my language beforehand and even if I tried I was immediately answered in English (which meant the crew understood but didn't want to answer accordingly), there was only one snack & beverage service on my medium haul flight and no beverage service on my short haul flight. To be fair, the planes were comfortable, the crew apart from the language issue was helpful, dynamic and engaging, the plane was clean and the directions were clear and direct. United has a lot of potential to be one of my favourite airlines, but the devil is in the details and a lot of them missed the target.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

Better WiFi. I cannot understand that in 2025, United is so behind on a technology that is now a necessity and still painfully unreliable, slow and keeps disconnecting.

The entertainment available didn’t work for anyone on the flight. Long 6 hr flight with no entertainment option and the staff didn’t know until an hour into the flight when we made sure they knew about it. They had no way to fix it.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

The worst landing I have ever had on a domestic flight. Thought we would lose the landing gear on landing in Newark. Then we spent 40 minutes trying to position the plane in the right place to be able to get the jet way to the plane. The plane arrived stopped. The announcer was that we were there. Everybody got up, then we were told to sit back down because they had to have us towed to a different position. We got towed and then everyone stood up and they told us we were in the wrong position to sit back down again, and then we got towed to a different position This did not happen immediately. It was 30 minutes while we wandered around a small section of the tarmac in Newark close to the gate, but apparently not close enough. Horrifying experience The CAB should be investigating that flight

Boarding was organized. Plane seats comfortable and service was attentive. Food options were good.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

I will never book a flight through Cheap fare. They booked me from Portland Main . And would not give me a refund, so I bought 2 tickets one for 299. From Portland Main to ORD. Then I had to buy a ticket from Oregon PDX to ORD that was another 440. So Just so you know they even told me it was there fault but no refund. Bad bussniess. I did inform United but they said they couldn't help me due to the fact I booked through Cheap Tickets. Never again. And I'm spreding the word. I let everyone know at my 50th class reunion

Poor seat in rear of aircraft Food at Admiral’s Club Terminal D at DFW inedible

Always seated jammed in rear of aircraft Admirals Club food at DFW terminal D was absolute worst food experience and I pay $600/year to eat this dried out junk

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

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

Flight attendants on this flight were very attentive and friendly

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

Vegas is such a quick flight that amenities aren’t the important part, in my opinion. Just get me there efficiently and safely, and that’s exactly what they did!

The flight was severely delayed due to the missing flight attendants.

Absolutely horrible. Usually pay $40-$50 to check luggage in. I tried to check my suitcase in and the price is raised to $70. That's ridiculously greedy c'mon. I had to leave my suitcase with all my clothes and hygiene products and repurchase once i landed in Atlanta. You guys make it really stressful to travel. Don't even want to travel anymore.

They cancelled the flight 3 hours prior departure. Had to spend $400 for a ne way flight with Delta Airlines! Spirit Airlines are not serios!

My luggage didn’t arrive at LAX, so that wasn’t a good experience.

Terrible seat, no in flight entertainment. No complimentary food or drinks. Seats really hurt my back after flying spirit for the day.

Plastic seat really hurt my back. Cannot even recline on the flight. Very hard to sleep on the plane due to terrible seats . Food and drinks were expensive and not very good. There were like 2 open exit rows behind me. My isle was full so I asked flight attendants if I could sit there. They told me it was a safety issue??? I think it more unsafe to have no one sitting there. In case of emergency, you’d want someone there to help.

The delays and the lack of communication and organization within the airport itself for Staffing this flight and coordinating the paper log necessary to depart was ridiculous and deplorable

It was a no show, so we got put in hotels for a nite. The A320 plane was very modern and flite and crew (if a pilot shows up were fine). Price was very good.

The entire staff from check in agents to flight attendants were pleasant and professional. Would suggest a complimentary water.
