Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The new seating arrangement is so over priced for what you get.

The problem with the seat assignments is that there were a lot of rows in the front that were empty but my row at the back was full. Just not so pleasant.

No food or entertainment, just a quick 40 minute flight. A little bumpy due to Santa Ana winds but pilot has no control over that. Good flight and landing!

Good but I prefer choose your own seat. With the new assigned seats they should board from the back I see no advantage to this new boarding. Just like every other airline

I realize they are still working out kinks with the new boarding process, but by the time I boarded in group 5, most of the bins were full. All airlines should better enforce small bags and jackets going under the seats until everyone has boarded.

WiFi was not working and didn’t have a beverage service

Snacks are always pretzels. Why can't you also offer peanuts ?

Flight boarded late after announcing on time boarding. Flight arrived only a little late despite late departure. Had trouble connecting to WiFi

Our flight when we finally got rerouted to a different destination than we were going was fine. But 2 days was taken out of our vacation because our flit was cancelled. We understand mechanical problems and of course don’t want to be on a plane that has mechanical problems.Wish there had been another solution.

Kayak wouldn’t refund me for a flight I was trying to cancel through Kayak. Alaska airlines said I had to cancel through Kayak. I called the customer service line and they couldn’t refund the flight that I booked through Kayak either. You stole my money. You will be hearing from my lawyer.

The bathroom trash container under the sink fell out and was like that long before my flight. The plane smelled of canned fish and floor was Deteriorating

I behave had better flights this one was old and poor

See previous. It was the flight from Honolulu to Kapalua that was cancelled.

Short trip from Honolulu to Kauai. Not a major issue. Only concern was the drop off of the luggage for departure. Only one person handling all of the passengers. She was busting her butt.

Good. Flight was good. Crew was good. Wish they offered coffee refills. Wish I didn’t have to pay for headphones. Otherwise good for a commercial flight.

My mother suffers from Lupus and has challenges walking. I specifically called Alaska airlines, stated her condition and made sure my mother’s had wheel char assistance towards gate and into the gate hall so she just had to get into the plane and walk a couple of steps. It was assured by Alaska team that the service was granted in both airports , DEN and SAN . In Denver , the wheelchair assistance never arrived. I had to personally grab another airline wheelchair sit my mom.Then I had to go to Alaska Airlines front desk twice to let them know my mother was waiting at the wheelchair service station. Upon arrival to SD Airport , there was no wheelchair service waiting for her in the hall before deplaning. She had to walk her way out in pain. Absolutely inconsiderate and unacceptable by the airline! Never again flying with Alaska Airlines.

Should have been forthcoming for reason for delay. Should have been able to check in for seat I'd like.

It was fine. It was a 30 minute flight so there was water or fruit juice and no food. Which was totally fine. The check in, gate and flight crew were all excellent.

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 😁

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.
