On time, smooth take off and landing, efficient boarding. Gate staff excellent, stewardess grumpy, but civil enough.

No WiFi available. It was too late to order food also. Guy next to me was huge (not fat) so had his shoulder & thigh next to me the whole way. Plane was delayed leaving PDX due to 8 other planes waiting. Not my best Alaska airlines flight.

Check in, they should have told me that upon arrival i needed to exit the secure area and re-check in with Eva Air. I wasn't sure what to do upon arrival at S.F.

Flight last minute delayed 2 hours for crew calling out sick

Laney was very helpful. I am computer illiterate. She helped me obtain a boarding pass and preferred seat. She was warm, friendly, helpful, and smiled. I was impressed.

Although both planes (flights) had mechanical issue delaying both of my flights, the crew members handled everything with ease. Both flights had the smoothest take off and landing. I opted to upgrade my seat to first class and really lucked out getting the seat at the very front of the plane. Awesome treat to myself. I really enjoyed my flight.

The staff from check-in counter to the flight crew were great. Flight was right on schedule. 10/10

Changed flight from San Fran to Seattle Then with a Delayed takeoff barely made my connection Waited over an hour for luggage 😜

Very comfortable - thanks. Only small criticism was the delay in disembarking caused by the passengers in the front two rows chatting to the cabin crew.

Probably one of the best flights I’ve had! From entering the airport, to boarding to landing.

We had to wait in line over an hour just to check our bags. It's a good thing we were so early to the airport. Only one clerk was working and the line was around the corner and down the hall. No good. I felt bad for her. Not sure how she kept her sanity with all the upset people. Then we get to our gate and there is no seating. Everyone was standing. Then I realize it is not a gate at all, we still have to be shuttled to our airplane. Ugh. Then we were late taking off and missed a window of opportunity before the airport runways were shut down for some reason. (not frontier's fault the runway shut down.) The seats on the airline are crammed and there is no cushion. Never had a tighter seating arrangement while flying. My 6' 4" husband was absolutely miserable the whole time with knees digging in to the seat in front of him. You think you are getting a good deal on a ticket, and then wham! I had to pay 75 dollars for our checked bags and 75 dollars for a carry on. No other airline does that!!! And also, there is a 40 pound weight limit on checked bags... Would have been cheaper flying with another airline, and I would have at least gotten a snack and drink. Was thankful for the tiny cup of water at least.

This was one of the first frontier airline flights this spring that wasn't delayed. It actually left on time. Some of the flight crew did not look happy, they didn't smile when the passengers were boarding or getting off the plane, and the passengers initiated greetings, not the staff. To me this was an odd experience to have with any flight/airline. I had a bad experience booking this flight. The price didn't solidify until late hours into the night. Ever time I purchased the ticket, I either received a denial email or an error because the price has changed, but it was never reflected on the flyfrontier or kayak websites until way after midnight on the date of travel. This caused me anxiety and irritation with the websites. Then I noticed a mishap with my name on my voucher as I went to check in, it was incorrect. When I proceeded to correct it, Frontier had no easy, let alone free, way to remedy it. I couldn't correct my name without a $75 charge, I couldn't cancel my voucher to repurchase it with the correct name without a $100 charge, because it was too close to departure. Then calling frontier was nearly impossible to remedy the situation with a human. It's already difficult to want to choose frontier because of all the upcharges, but you feel kinda trapped into doing so because it's the more affordable airline.

They canceled flight. Hard to believe there was even a plane incoming for us to get on

The worst. We never made our connection and they did absolutely nothing to help us at the airport.

Our flight was cancelled. They could do nothing to help us get another flight that was timely. Because the first leg was cancelled we were unable to get to our connection. We had to book on an entirely different airline for today. So we spent more money, lost a day of vacation and will never fly Frontier again, so the 'we are sorry, here is $100 credit' is a joke since we won't be flying on Frontier.

No way to get boarding pass on my phone. In order to print the bag ticket a boarding pass is needed. Asked the agent to print me one, they said they typically do not due this as its so much work. I showed the email confirmation and I asked how i could do it my self the agent replied he did not know as there was no link. The flight was delayed due to an attendant forgetting to come to work. On the flight no drinks were offered only for purchase meals.

Since you have to pay for overhead bags then they shouldn't be running out of space and asking individuals who paid to remove stuff from the overhead

Cancelled flight after I arrived at airport after 75 min drive and parking. Next flight was 4 days in the future. Had to scramble and buy a much more expensive flight on another carrier.

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.
