Flight attendant was excellent, pleasant and attentive. Announcements were clear and pleasant.

seats good, foot space comfortable not good, waiting on tormack at Las Vegas

6 hour flight from Seattle to Dulles airport without any WiFi and movies, as well as now snacks is crazy. We were told no WiFi and entertainment 5 hours before departure.

Wifi would be nice. Unfortunately the particular airplane was not equipped with wifi.

I'm so glad that Alaska still keeps this little "puddle-jumper" route going between SEA>ALW; my daughter lives on Walla Walla, and it's so much quicker to be able to fly right in to Walla Walla than to have to fly into Tri-Cities and then make her drive 40 minutes each way. This flight is usually only 50%-75% full when I fly it, but that's because it doesn't get in to ALW until MIDNIGHT! But thanks for continuing to service the Walla Walla area, Alaska!

Seats very comfortable and legroom appreciated. All in all, it was a great experience.

Original flight was canceled, and the automatically booked second flight was immediately delayed. I arrived about 4 hours later than planned with only a $12 meal voucher that didn't fully cover a sandwich at airport prices.

I was expecting better service from Alaska Airlines. I registered for assistance since I have a disability. The terminal in Seattle, WA was very unprofessional and at times rude. The BWI location was the exact opposite. I will NOT consider Alaska Airlines for future flights.

It was very good and comfortable, Crew was also great

The flight was delayed almost an hour. No wifi on flight.

It was okay delay was long but I made it

I have never flown Spirit it was much better than anticipated!

Staff was very friendly. They attended to people nicely and reprimanded, in a professional way, to those who wouldn’t listen. AC wasn’t working on the flight waiting to depart in Burbank, so it was uncomfortable for a while since the flight was delayed but then better before take off.

Good on that leg. When I arrived in Detroit I had to wait over an hour for luggage.

The crew was very nice. I would like to see them offer basic refreshments just like a soda and pretzels, etc. for free.

I missed my flight because I was not informed that I had to check in 45 minutes before my flight and I was not allowed to check in any time after that. I was there at boarding time and their customer service was poor and they told me since I didn't check in 45 minutes prior, I couldn't get my boarding pass. I received an email containing my "e ticket" which I Thought was going to get me boarded.But but they said that was just an Itinerary and it was no good to help me get on the plane. I had already missed one flight earlier that afternoon and had to pay for this flight.And then when I missed it they told me it was gonna cost me another $99 to reschedule my flight

Seats uncomfortable, hard to check luggage, etc. It was like the last flight out of Hanoi

Good experience except for the drunk woman who was with a child. Sad

The flight was canceled and no option was given to get me to my destination even though there were 3 other flights going to Las Vegas later on that night. I will never fly on Spirit Airlines ever again. Terrible service!

I book a filght for me and my daughter from Miami home to Las Vegas and getting her checked in was awful the lady at the baggage check in was horrible!!! She was the rudest person I have ever encountered in my entire life!!!! My daughter dose not speak Spanish and so I was trying to translate for her but the woman would not let me so my daughter was 100 💯 confused because she could not understand what was going on or being said at all horrible absolutely horrible and rude extremely stressful worst experience ever!!!!!!! And then we were actually told by other air port staff not to complain because if we did sprint would make sure we miss our flight ✈️ that they do it all the time 😧
