Thank you still providing bags for vomit. My son had a migraine and needed a bag to vomit in and it was right there behind the seat in front of us. Thank you!

Thank you still providing bags for vomit. My son had a migraine and needed a bag to vomit in and it was right there behind the seat in front of us. Thank you!

Well, the baggage porter on Maui told my mom that our carry on luggage was overweight and if she gave him a 50 dollar tip he would let it go through. She tipped him and he tells us that he needs my Alaska airlines cc to waive the extra baggage charge. Find out later that since my original reservation was not under my name using a Hawaiian airlines CC, I would have to pay for the luggage anyway. I told them I had to end up paying for my daughters ticket when you all said because she turned two using my Alaska Airlines cc, now they need to charge me for her seat/flight, but you guys didn't care and i ended up paying for the bags and my mom paid the porter 50 dollars extra for nothing .. It was a crappy experience. First it was a multi trip. PDX-HNL then HNL-OGG then OGG to PDX. All bought under one ticket. My daugher turned two during the flight from HNL-OGG, but when I bought the ticket and at the PDX airport they said since i bought the ticket before she was two, everything is fine. come to find out no, I had to pay her ticket HNL-OGG and again OGG to PDX. you guys scammed me. You should say it on your website and make sure people know that during flights if the child turns two they have to pay for their seat. If i knew that from the very beginning i would have bought her ticket and it would have been LESS than paying TWICE for her flight! and you scammed my mother with you porter who told her to pay him 50 dollars and he would take care of the extra luggage weight.

Flight was great. Boarding was crazy because another flight was boarding late next to ours so everyone was standing and in the way.

It was a quick flight, but coffee would have been great!

I can honestly say in the 54 years of my life this was the worst flying experience I have ever had. I was delayed on the tarmac going into Dallas for an hour and 2 hours on the tarmac leaving Dallas. a 4 hour flight turned into a 6 hour flight due to Alaska incompetence. To be honest I will never take another Alaska flight.

I am mobility challenged and ground crew were accommodating to my needs. One must walk up a ramp to board Alaska planes. Terminal to tarmac to ramp to plane.

The attendances were very thorough and pleasant during the entire trip. The pilots did an excellent job keeping us posted on what to expect. The landing in Portland was executed professionally and perfectly. Boarding was delayed a half hour. But given the times were in, that was no surprise. All in all, my preference is to fly only Alaska Airlines for their reliability and professional service.

All good! No entertainment on this new plane yet but ok for this short flight. Great on time flight! Thanks

These questions are hard to answer. It was not until I checked in that I learned my flight was going to Seattle for a connection and not Portland. I did not get notified, or asked, about this change by Alaska or Kayak. Thankfully I made this flight; but missed the connecting flight and it took me much longer to get home. A service representative for Alaska says this happens frequently with third party companies, like Kayak. Please please figure that out.

I got the last seat on the plane, in the back in the corner against the window, and I paid a competitive price for my ticket several weeks before the flight.

Great overall. There was a bit of turbulence so they could only serve water because too much turbulence for the carts. Was glad they prioritized safety though

Excellent flight, the planes were newer, they did a nice job with boarding, great service overall.

Great service. Flight was delayed while we sat on the runway for a couple of hours. Weather related. Staff made is very bearable. The steward servicing the first class cabin was exceptional. Thank you! 💗

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Amazing flight! I have never noticed the uniforms of the attendants before in twenty years of flying except today when one female had the most amazing dress on. It was beautifully designed and showed she was in charge. I never dreamed I would google who designed Delta uniforms . The ultimate compliment is when another woman admires your outfit. . I hope your designer puts it on the market

It would be nice if was given wires ear buds. Overall was a good experience was able to sleep on the plane

My flight was 6 pm 6/6. Every hour they delayed it again - air condition issues then no pilot then the crew had worked too many hours and cancelled the flight at 11 pm. Sent customers to NJ a 45 minutes uber ride to a hotel. Had to be back by 5 am for a 7 am flight and again no pilot etc with another three hours of delays.

The entertainment and wifi mostly didn't work on this flight.

Terrible entertainment system - kept freezing and audio kept cutting out. Snacks were mediocre at best for a 5 hour flight.

The check in and bag drop off for Sky Priority members is slow. The Clear security was also slow - a TSA issue.
