The flight itself was okay, but there were 2 screaming kids in front of me my entire flight which made it just awful. The parent did zero to try and make the children settle down and flight attendants did nothing either. I understand it's hard to travel with children, but constantly yelling, screaming, or loud talking for 4 hours straight is just ridiculous.

There was an issue with water that led to us not having potable water onboard. They dumped the onboard water and we were two hours late taking off.

All good. Great food and entertainment when there isn’t any on a one hour flight

Boarding for Alaska Airlines is always chaotic with many people crowding the gates. Arriving in on Alaska in Los Angeles is always interesting since there is never a gate available. So the planes are often parked all the way out on the west side of the airport while waiting for the gate to be cleared of the departing plane. This flight was no exception.

Flight was delayed about 45 min and they never offered an explanation. Peruse, staff were friendly and competent and the flight was safe.

It was a really smooth flight. I hate heights. All made it feel smooth. Thankyou

No TSA pre check on boarding passes. Was told known traveler numbers are only kept with Alaska Airlines mileage plan members. Did not notice until reached the head of line, and then was sent back through the line to general boarding which took almost an hour. Learned two things: check our boarding passes, which we haven’t had to do with our other airlines, and don’t fly Alaska! You used to be much better!

I wouldn’t fly with Alaska again if you paid me.

I’m still waiting on my luggage. They canceled my flight on valentines day and my girlfriend broke up with me. Alaska airlines literally ruined my life.

Flight was delayed twice, I was forced to check my bag, and the only offered water or apple juice on the flight

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

I loved having a most black flight crew during Black History Month; rather by design or accident I appreciated the representation. ❤️

This was the second flight this week with flight attendant Marcus I’m not sure if his last name is Lane or Lang but this guy is awesome. He funny, attentive and his service is 5 stars. Marcus makes business travel more enjoyable !

Although the flight left late, we arrived early. It was one of the quickest boarding and off boarding experiences I’ve had. It was kind of annoying the only drinks they had were water, coffee, and tea. The flight was very smooth, temperature was just right, and flight attendants were friendly.

Lower number on this flight so spaced out passengers. Able to enjoy more room to relax during flight. It was lovely.

Kind staff. Snacks are small but that’s the new normal.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.

Flight left early and arrived early. the whole trip was excellent.

Seats were really tight and the seat belts did not give enough slack.

Our seats were all the way in back of the plane,

The seats on this flight were almost roomy enough to be the basic amount needed for human existence. I think my favorite part of this flight was it landed at an A gate, which was the most palatial part of Sea-Tac I've ever seen - a massive improvement from the S gates.

The seats on this flight were almost roomy enough to be the basic amount needed for human existence.

The flight attendants in First Class were mediocre at best. They did not take our tray away until we were about to land and only did so when I press the call button. The United person at the United Club was asked to get us our boarding pass since we missed the flight due in Chicago. She argued that we did not have seats on the flight given to us in Moline. Furthermore, she was adamant that we did not have a First Class ticket. After I spent much time with her trying to show we were correct, she reluctantly agreed. She was probably the most incompetent ticketing person I have ever met and I have traveled 3 million miles on United plus many additional miles with other carriers. United has definitely deteriorated in more than on way.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We arrived early and finally made it to our gate almost an hour after.

Was a pain having to leave the plane and reboard but glad the plane was fixed

Plane was was better than th YVR to ORD flight but was a fraction of the distance. Fly your better planes on longer distance flights.

Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.

They need to improve their boarding process. Group 1 and/or paying first class passengers shouldn't be in the middle of boarding process

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

Most of the delay was due to weather which is not what was at issue here. One delay was due to a missing flashlight and in the end the flashlight was actually found on the plane. The entertainment system is very limited. Live TV options offer only a few channels that are not very appealing. Boarding and deplaning are always difficult. It just takes too much time to get on and off the plane. On the plus side, I missed my connecting flight, but was easily able to book a later flight from the app while enroute.

You were more on time than United. I'm so over united delays.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

I chatted with the captain before the flight, and similarly during the welcome announcement, he warned of a turbulent flight that may impact the in-flight service. However, once at altitude, he announced that the weather changed and he immediately turned off the seatbelt sign. But it appeared the cabin crew had already decided to take off this flight. They remained seated and then just chatted in the galley. The flight was fully catered, but only first class received service.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Baby cried a lot. Nothing anyone could do about it. Just part of flying.

The flight crew was fantastic! Which the seats had a small TV.

The check in process was a mess for no reason. I spent an hour waiting in line trying to get them to print my boarding pass and as a result I missed my flight.

The airline used deceptive tactics to charge us more for our trip. Search Frontier Class Action Lawsuit to find out more or read the hundreds of reviews that have nearly identical stories.. don't fly this airline.. you've been warned.

Check in at Philadelphia international was absolutely terrible! I fly 2 to 3 times a month and avoid frontier at all cost and will never fly Frontier again! The night before travel, I tried checking in however, the app was giving me an error, so I went to the desktop, which instructed you that you need to use the app. The next day I presented at the check-in gate after trying at least a half dozen times prior to getting into the airport and continuing to getting the error in the app. I actually had rebooted my phone numerous times and reinstall the app just in case. My phone is only one generation older than the current model. It has no problems completing a frontier flight purchase or any other app issues. There was only three frontier employees working at check-in and a huge line while I was in line I continued to try and check in via the app. As I approach the desk, I was dreading dealing with the agent. He was extremely unprofessional, anti-semantic & very ignorant, and mean to the people in front of me, as well as the people who ended up being behind me. He literally told people “Man I don’t care bout y’all” in his native dialect! Maintaining my composure I approached and explained the situation. To which he replied, you’re gonna have to pay then! I don’t understand. It’s an issue with their app not allowing me to check in! Not my issue! He told me if I pay cash it would be $15, $25 if I pay credit card. I don’t understand a $10 difference for paying with a credit card? I am completely cashless so I continued to try using the app to avoid the $25 fee, Which I still don’t believe that I should be responsible for since it was Frontier’s technical issue!!! I continued to check in via the app a couple more times after he verified I was doing everything right he proceeded to continue to belittle the people behind me. Yelling at them saying I don’t care about you people! I cannot believe that this is the way that businesses would treat its customers! Unfortunately, the black mail with dreadlocks did not have a name tag all he had was a frontier sweater on! For the $25 fee that I ended up getting charged on my credit card. I should’ve just booked originally with Spirit or any other carrier! I have no problem paying fees that I should be responsible for, but when it’s due to a technical failure of a company, the customer should not be responsible for it! I cannot believe that it’s not frontier going out of business!

they delayed my flight which ended up, causing my layover flight to leave without me, resulting in me missing a flight and having to stay overnight in Houston international. I got no compensation other than a flight to my original location only a day later. i’ve never experienced such a unprofessional situation

Very easy with the app to board and staff skills

After waiting several minutes to be acknowledged by 3 employees on their phones, was told we had missed our flight because the doors were closed at that literal moment. Had they given any actual service or help while we were standing there we would have been on with time to spare. More than 10 people were turned away in this fashion claiming there was no way they could let us on the plane, even though it was still sitting connected to the terminal. After the desk agents let us know they didn't care about the situation we were forced to pay more than twice the price of our original tickets as no credits were given for the price of the "missed" flight. And the icing on the cake was after being treated poorly, fleeced for another few hundred dollars for new tickets? We waited on the next plane for 25 minutes passed the "doors closed" time, letting almost an extra dozen passengers on board. You're company has lazy, disinterested employees and your lack of any real help will ensure this was the first and last time we fly Frontier. Awful.

My experience with the phoenix airport was terrible, the personnel lay the ticket counter charged me for a carry on that fit in the carry on size box, and the two women I spoke with were terribly rude and not willing to help.,,, there was one lady “candy” on the flight crew that was amazing and is the only reason I stayed on the flight at all, because the other stewards helping people to get seated on the plane were terrible

I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.

The plane was clean, the crew was friendly and helpful. It’s a low cost airline so there was no food, drinks or in flight entertainment but we didn’t expect any of these things. In the room for improvement department, they should install USB ports in seats to charge mobile devices.

The seats were extremely hard and uncomfortable, even for a budget airline.
