Super easy on both flights. Alaska is my go to airline!

Read more about Alaska Airlines

Super easy on both flights. Alaska is my go to airline!

I appreciated the check-in at SEATAC - a knowledgeable person was available. I found it easy to ask questions as I went along. I hadn't been at SEATAC for a year and was not that familiar. Parking was fine at Sacramento

My baggage arrived at the airport on an earlier flight. It would have been nice if I would have gotten a text. I waited until all the luggage had arrived before Ivwent to the baggage counter!

I had to check-in my small carry-on at the gate which was inconvenient. According to the people at the gate at SEATAC, there wasn't anymore room in the overhead bins. I obliged. But, when I got inside the aircraft, there was plenty of room EVERYWHERE! It was either miscommunication or incompetence among the Alaska personnel.

Bad. The fight was late and they gave a ridiculous $12 stipend. Better give something or nothing. $12 is ridiculous.

It was a good flight . It wasn’t a full flight so we had space to move around

Great as always. Alaska is my top airline when flying to/from the Pacific NW. I was a bit anxious when I found out I was in a 737 Max, but it went well for us.

1. Stop cancelling flights 2. More overhead luggage space 3. Get rid of the cardboard cups for drinks

The SeaTac tsa process is the dumbest in the land. Slow for no reason. Alaska was fine. We made good time but had no where to park so we sat at the gate for 30 mins.

It was the usual. The entertainment did not work on my iPad but worked on my phone

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Bag drop off was slow and annoying. Only 2 agents at the entire delta desk, and no one directing traffic for what line to be in, many confused people slowed down the process. Boarding was fine. Seats in Delta comfort plus were fine. Snacks were great! Definitely a bonus. The entertainment system was awful — old, slow, not responsive, and completely unable to play games due to some kind of error. But on the other hand, thank you to Delta for the free WiFi. That made it better.

Flight diverted in SD. Later take off in Seattle by 1.3hrs

Mi primera conexión se retrasó por lo cual perdí mi segunda conexión la cual salió adelantada

Crew was not friendly when I went to request a seat change.

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

The flight crew was amazing. I’m very tall and they moved me to an exit row unsolicited!!! Amazing service.

Really impressive staff at airport and on plane, especially given how busy it was

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Boarding in Seattle is always a mess. Sat in Deltas new domestic first class cabin. Everything was great except I found the seat cushion to be fairly uncomfortable. I’m a bigger guy so take that into mind (6’2” / 300 lbs.). Crew was meh.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

United airline kept delaying our flight back to Phoenix for 8 hours before they cancelled it! If they know that we are not flying out for whatever the reason is, why did they keep lying to us for hours. We could find another flight earlier or even find a hotel with a shuttle. But cancellation at about midnight was not fun. We stayed in the airport all night till the following morning when we bought an Alaska tickets to go back to Phoenix. Total of 14 hours in the airport.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

My experience is based on one crew member. I had found my seat and sat down but there was a gentleman to claimed to the flight attendant I was in his seat. She then came to me and curtly said, "I need your ticket!" No hi, no excuse me may I see your boarding pass? NOTHING! I was taken aback by her attitude and she repeated herself, "your ticket?!?!" I calmly responded with ok, here you go. Only to discover the gentleman was looking at the wrong boarding pass. She gave me back my ticket with no apology. She then was curt with another man who was putting his coat in the overhead bin, already helped by another flight attendant who said it was fine. She realizes it's ok and then asks him if he drinks. The look on the man's face was priceless. She said she was going to comp him drinks. He gets offered a comp drink for a coat as well as an apology, and I got no apology.

Flight cancelled because of the grounded 737s. United was good about it and got us onto a later Alaska Airlines flight to Oakland (not San Francisco as originally intended). Had to go through security again and my wife dropped her MacBook Pro, which broke, a $2,500 whoopsie. But we made it home.

Delays, excuses, delays, and more delays. This company is BROKEN.

Horrible. Delayed on both planes several times. No attempt to fix it

I contacted both carriers months beforehand to change the cabin (booked in April) but to no avail (united asked to contact Swiss since it was their equipment, Swiss told me to reach out to united). So yeah… My seat was pretty worn down, legroom on 27K was more than enough, but still economy seating so, getting to know your neighbours was easy. According to ground staff, the flight was massively overbooked- and this showed. I ordered a gluten free meal beforehand (which was honoured) but for breakfast got a bread roll and croissant 🤷🏼‍♂️ The connection itself is great. Leaving SFO late PM to arrive at ZRH in the afternoon makes it easier to get re adjusted again. However, and since I’ve flown this connection a couple of times in the past, I will rather deal with one carrier only and include a layover on the east coast.

United requires seat selection in order for those booking together to stay together.

Delays!!! Maintain your planes so your customers don’t have to sit on their assess for over an hour on the tarmac!! Also, United app is buggy. Videos did not load. Overall a miserable experience. Flight crew was awesome though.

5 hour flight - full flight - not enough room to use my computer - slightly delayed - Admirals club was excellent quality food, drink made up for flight seating. No food offerred on flight, you ahd to prebook.

I had the exit seat with all the leg room I could ask for. Great!

I wish there were no credit card announcements. I paid hundreds of dollars, I don't need to pay again by sitting through advertisements.

Plane felt so crowded and tightly packed. The chair itself was not comfortable.

This was a Business class award ticket redemption using Alaska miles. Flagship Business was great for a transatlantic evening flight!

The flight got delayed more than an hour due to maintenance issue after the passengers were all on board. I missed my connecting flight and had a trouble finding a next flight. The crews didn’t seem to care about the inconvenience of the passengers missing a next flight. It was very frustrating experience flying with American Airlines. I will not fly with AA in the future.

If they could pack the seats closer together they would...

The flight was delayed, so connections were missed. While in flight, they helpfully booked on another flight with another airline to the final destination. But failed to provide any information such as it entailed first flying to another country, waiting for several hours, then flying on to the final destination. Luggage is....somewhere. Maybe it will be located, someday.

Flight delayed several hours so missed connection. Plane boarded from the front to the back made things excessively slow to board Seats to narrow and I'm a very slim person Food was awful - had diarrhea for hours after eating it Heathrow transfer was a nightmare... few people at security, check through took over an hour. No one seemed to be in a good mood of the staff. They all seemed annoyed by their jobs. One large argument between manager and his staff. It will be difficult for me to consider flying BA again after such an experience - certainly will reconsider ever flying through Heathrow again.

Nothing really nondescript, the flight attendants were friendly and helpful.

There was no wifi, there was no usb charger on the planes Frontier lowered the weight limit on suitcases from 50 to 40 pounds Frontier now charges for a seat...really? If i don't pay for a basic seat, do i stand the whole flight? Frontier now charges for the carry on, just like for the checked suitcase The bundle pricing is way over priced.

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

absolutely horrific. delayed flights, overbooking. over charging. nightmare service beyond words. stay away.

My husband didn't get boarded on this flight. He was asked to pay $50 extra by the Frontier staff to get two boarding passes for check-in at the Las Vegas airport. He refused to pay this extra $50 charge and tried to do check-in online by himself but it seemed to be late with only 7 mins left. It ended up that my daughter and my husband missed the 7-minute time window. They had to take the next non-direct flight which took more than 12 hours from Las Vegas to San Francisco, a very poor experience for them.

Frontier is a no-frills airlines were the focus is low cost. You get basic service so don't set your expectations high. Watch out thought because this airline, like a few others, will try to nickel and dime you.

Was charged 99 dollars for a bag despite agents previously telling me it would be ok. Customer service was unhelpful
