we were late due to plane's late arrival at the gate and then there was a glitch with a button or something that had to be fixed and we waited for a tech to do that . The flight was very bumpy and totally not anything to do with the plane or crew. Just saying what was a bit miserable and kind of worrisome give then recent circumstances with the planes. Nothing fell off or onto anything during the flight of take off and landing so I count myself lucky to have gotten to my destination there and back safely. Thank you for asking

I'm a tall guy. Fortunately I was able to find seating in the emergency rows that gave me a couple more inches of room. My return flight a few days later, I wasn't as fortunate. Very painfully and uncomfortable return flight.

Flight was smooth but to many screaming and crying young toddlers who wouldn't stop crying and screaming at the top of there lungs it gave me a bad headache.

They misplaced our 1 bag and that messed up our reservation for the following day of fun and we paid extra 100 for the bag. Not fun

Crew was friendly and professional. Offered multiple drink services. Handled this full flight with style and grace.

Horrible, missed my connecting flight because Alaska did not give me enough time

Great crew. Uncomfortable cramped seats. Crappy snacks. But on schedule and no doors blew off.

Everything was great until one of my 4 checked bags didn’t make it with me. Baggage staff at OAK were not especially congenial the first night. Got my phone number wrong so they couldn’t reach me via phone. I was able to pick my bag up within about an hour of when I initially wanted to. Wendy was very helpful.

I was on a ski vacation and traveled between Pittsburgh and Big Sky, Montana via Seattle I was very disappointed that I couldn't reserve a seat between Seattle and Big Sky ahead of time and angry that I had to pay a fee to get a seat (both ways) when I checked in online. Why couldn't I select a seat ahead of time for that leg of the fight? The flight itself was fine and the seat was comfortable. On arrival back in Pittsburgh, I waited over an hour for my skis to arrive after I retrieved by boot bag from the carousel. This was my first experience on Alaska Airline and it was disappointing.

One of their flight attendants made a rude comment as I deboarded the plane. Definitely won’t be flying with them again.

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

Really liked the choice of the 4 free snack options. Crew great. Good vibe on plane.

More filling food and more entertainment options would be cool.

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Flight and seats were great. Food service was average at best. The real main problem we had is that we got cheeseburgers for the kids but the plates was extremely hot. Like ridiculously hot and the stewardess never said anything. Luckily or unluckily my wife touched the plate and was able to deal with it before the kids got burned.

There was no wifi, there was no usb charger on the planes Frontier lowered the weight limit on suitcases from 50 to 40 pounds Frontier now charges for a seat...really? If i don't pay for a basic seat, do i stand the whole flight? Frontier now charges for the carry on, just like for the checked suitcase The bundle pricing is way over priced.

I am HIGHLY unhappy with the amount of money I spent on the flight. Paid in advance only to find the flight at a discount price a week or so before the flight. I will not fly frontier again and have bad mouthed your business since to anyone I have spoken with about flying (which has been many a people). Crew was mediocre and instead of moving me to a spot where I could gain some leg room they sat their flight attendant there. Won’t be flying frontier in the future.

They changed my flight and did not want to accommodate me or try to help me in any way. They do not care about their customers.

Plane was clean but they do not allow bag drop until 1 hour before flight. Just encouraging late fees and other issues. The worst I have experienced. Total hostage situation, pay or you miss your flight.

Everything was good, 20/30 minutes late waiting on a crew member. It’s hard to keep employees. Or serious employees I know. I remember one flight from Houston of Frontiers was almost 18 hours late. And another 4 hours late very poor. But I would rather be late and safe than the on the news. Thank you.

Well, I didn’t have food! So NA wasn’t an option. I’ll be back!

Bought seats on the flight and they were supposed to be 2 and a jumpseat. Plane clearly changed and it was a regular 3 seat row. Asked for a refund and was denied. If I wanted to sit next to someone else I wouldn't have bought the seats..

I dunno. Depressing, uncomfortable (I’m poor), but on time and efficient.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

First time flying with Frontier . From buying tickets ,getting boarding pass and boarding plane was super easy. Definitely would fly again with Frontier .
