No headphones provided. No gf food. Only 1 beverage cart run sAN to HNL. Rarely saw crew members

The check-in crew for Alaska was rude, unhelpful, and the opposite of customer-centric. We arrived 50 minutes before our flight and were told it was too late to check baggage. When I asked what the cutoff was, the agent started speaking in codes “D50” and yelling to their manager who also spoke in codes. They then tried to speak to me using these codes and all I wanted to know was the time of the cutoff, which they would not — or could not — articulate. They booked me and my family on the next flight while smirking.

Generally Good. Outbound flight was marred by a continuously s creaming baby. Fortunately the flight was only 90 mins long it would be nice if people traveling with small childres could be centered in one part of the plane. Also, you need to adapt your servey to include a "not applicable " option for things like food and entertainment, which are not offered on shorter flights. I fily Alaska by choice as given all the cirumstances, I fel\el you do a good job.

A solidly good experience, but would’ve appreciated more communication with regards to travel delays.

I wasn’t aware that we needed to supply our own screens for entertainment

Alaska Airlines staff go out of their way to accommodate my fragile musical instrument, every time. They are unlike any other airline. I've experienced this can-do attitude on several flights with different staff, so this must be the culture of their company. I appreciate Alaska!

No issues and clear sailing. What a preferred to have sat in one of empty seats other than my assigned seat that would be my only complaint if it was to complain.

Perpetually delayed, flight out was delayed almost 2 hours, flight home was delayed an hour and a half. On the way back no refreshments as an option, yet they gave it out to 1st class. No apology or notice of the delay going out both ways. Seats are nice feature wise, but the adjustable headrests don't stay up anymore. Feels more like a budget airline

The ticketing counter in SD was a mess. The lady handling the First-Class check-in seemed overwhelmed until a supervisor replaced her. It took almost 20 minutes to get once couple checked in, and then she started walking around the counters while 7 people just stood in line. Once her supervisor arrived, she announced she was going on break, never to engage with customers again.

It was a bumpy flight but the crew was very attentive and made it a safe and enjoyable experience.

Every staff member was professional, friendly and courteous. The pizza twist was ok. It was warm but too much dough.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

Flight left on time and we arrived 25 minutes early! There was a gate available when we arrived so early on a busy Sunday afternoon! Flight attendants came around twice with the drinks cart.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

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

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

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

Wifi was spotty. Tray table was very dirty when I sat down.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Delayed for mechanical and no updates on what was happening and how long the delay might be.

A first class seat should fit a fat person, and this doesn't. The trays in the armrest are less functional than an ordinary tray in the back of the seat.

The experience at checkin for my American Airlines flight from Sacramento to LAX was very good including the assistance I received in getting my bags checked in and boarding passes printed. Was pleasantly surprised the my bags were checked through all the way to my destination at Clark International Airport in Angeles, Philippines.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

The flight was significantly delayed for 6.5 hours because of snow. There was no communication once the plane returned to the gate regarding when the flight would resume. Other flights were departing while our flight was being unloaded for reasons unknown. Our flight also seemed out of the queue regarding further deicing, refueling, and waiting to Taxi to the runway.

They are always late and seats was also not having working charger

did not have enough meal for first class passengers so offer us snack
