The seats are very small. I’m 5’ 3”, so don’t think I should notice. The food selection was non existent and very disappointing. 5 hour flight plus TSA, etc. I would have appreciated a small salad, crudités. Something fresher not just chips.

The seats are very small. I’m 5’ 3”, so don’t think I should notice. The food selection was non existent and very disappointing. 5 hour flight plus TSA, etc. I would have appreciated a small salad, crudités. Something fresher not just chips.

Was notified the departure would be late. Later on it was suddenly on time. Traffic by LAX was horrendous, and I missed the flight.

you sent me to some shitty "Airfaireassist" thing that did a bait and switch on the faire. Won't be using Kayak ever again

Every thing is on time, boarding, landing nice and smooth. But No tv? No food for 6 hours flight?

I don’t think Alaska coordinates with Kayak. I did not get a “check-in” email inviting me to check in 24 hours in advance. Had to wait 20+ minutes to get a wheel chair.

The plane was delayed which was annoying. No seat back screens is a bummer. Staff if great

First Class seats had no more legroom then Premium Economy. There was no working WiFi or entertainment. I would have rather paid $400 more and flown on United for the 6 hours from EWR to SFO.

Overall the flight was on-time and plane ride very comfortable. The free snacks not so good - only a small bag of pretzels and no milk. I wanted milk. There was not entertainment on the plane unless I wanted to download their APP. But I would consider flying with them again and be more prepared on my part with food and entertainment.

This was more with the third party booking through Kayak but my KTN for Pre-TSA, even though I entered it, wasn't assigned to my ticket when I got to the airport. I had to go through regular security. Also the Alaska app had trouble loading my ticket in the first place and I had to ask for it to be printed. Alaska Airlines was great but wanted you to know about this hiccup in the ticketing interface.

this was the THIRD time in four Alaska flights that were 2 hours late. Only one was due to weather. The intentionally posted each flight as only 1 hour and 55 minutes late so that they wouldn't have to give out vouchers. And then the flights all ended up more than 2 hours late. Makes United look like a premium carrier.

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

Great for the price. No wifi or entertainment, but gate agents and crew were fantastic and we boarded quickly and left on time.

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

Both legs of the flight were changed. The day of the flight and length of the trip.

First of all, we never got on the connecting flight to Denver. They delayed our flight for two hours. If we would have gotten on that flight, we would have been stuck in Denver for 13 hours. So we re- routed our flight for a straight through flight to Oklahoma two days later. THEN, they delayed that flight for two hours. After that we were able to finally get on our flight and come home. Frontier Airlines - one of the worst airlines I have ever been on.

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

Very bad! No good service delayed my second connection flight
