Why do you ask about food when only a snack is served? Actual food needs to be bought.

There was an older male crew member that was very rude to me when doing the last checks before pulling back from the terminal. There is a polite way to tell someone to put their bag under the seat. It was Mother’s Day and my mom has recently passed so it was a tough morning for me in general. There was no need to make for the snide remark “ I don’t know how many times we have said this already” as you walked away. I had held it together all morning and this interaction brought me to tears. love Alaska Airlines and this is the first time I’ve had a negative experience.

Alway a a breeze! And great mountain views on left side of plane during entire flight!

another delayed flight. no one at the desk kept us updated. we found out by an email as the desk was not even staffed up to expected takes off

They canceled my flight going back to SF after I was at the airport. Wanted me to take a flight 14 hours later. Not a happy camper.

Service was excellent. Staff at check in cleared hurdles for me so I could travel with my service animal.

Flight cancelled an hour before takeoff due to "unscheduled maintenance". New flight makes me have to wait for 5 hours in the airport, at a gate totally on the other side of where I'm at, requiring me to take a tram to get from the N terminal, to the C terminal. After waiting for 5 hours I'm informed my new flight is no longer at the gate I'm at, but instead is back in the N terminal where I was previously.

Delayed an hour and sat without updates. Ended up an hour late to destination

The flight was decent again if there was a place that you could put crying children that would be great. Or maybe make a rule against allowing infants on the plane.

Everything was fine -- on time, clear, clean. I don't want to pay extra for in-flight wi-fi

The plane from SNA wouldn’t start after 5 tries. The team gave me an option of flying direct from LAX and giving me a Lyft ride there! Perfect!

Had a broken tray in business class. Crew just shrugged it off.

Everything was great except for the seat. The backrest would not stay in the upright position.

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.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

I’ve had a couple flights this week on United that were delayed by an hour or more

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The plane was dirty and the in seat air wasn't blowing as planes usually do.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.
