I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

I don’t understand the purpose of the orange “priority” tag on my bag. This tagged, my bag is last or near to the last bag to come down the carousel at IAH.

Plane 3 hours late. Missed connection. No help from gate staff. App horrible. Lost connection repeatedly. No service desk. Finally got help from young girl driving cart.

Oh my gosh, I loved my experience with United! they made me want to travel more often.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

The bag drop personal were not helpful. There was no food on the flight. Boeing aircraft, lousy as always. Everything else was fine.

Asked several times dairy free options and was ignored. Was told chips was the only thing I could have that I should have put it on my profile “which it is”. Very unprofessional. WiFi didn’t work have the flight. Overall a very bad experience.

Plane still had screens for watching movies. Good selection too.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

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

The plane was so gross and dirty. Literally saw dust layering and flowing out the grey vents. Dust was all over the air vent knobs to the point where I took my sani wipe and cleaned them down so at least it wasn't blowing my my face. Also, I upgraded and paid for Wifi and it's always so spotty. I get we are in the air, but don't charge for it if it's not going to work. I expect so much more from United. They really are giving up.

Plane was pretty clean, staff was friendly and helpful, flight left about on time arrived early. Took a long time to board and get off the plane - carry on items didn't have enough room so people had to move all around to find places.

Service in first class no longer exists on American Airlines .

My seat was very worn. Otherwise I had an excellent flight

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

Always a great flight on AA. PHX to DFW and vise versa is always going to be a pretty full flight but the crew handles it phenomenally.

also wi-fi never worked attendant said satellite coverage is spotty over water ..... but we were over land!

16 Hours delayed, NOT because of the cybersecurity Microsoft issue, but because we were one flight attendant short, then when the missing flight attendant showed up two hours later, the flying shift of our pilot had expired, so, now no pilot. American Airlines is the new Spirit Airlines, actually, that is not fair for Spirit, they are probably better.

Worst flight in terms of service and food. Attendants were inexperienced, no preflight drinks, did come and give us hot towels until well into the flight. The left the Curtin open between main cabin and everyone from the main cabin went to the fist class bathroom. Food was awful! Had the golden chicken and was too lemony and inedible. No offer of coffee after. Awful!

My morning PHX to NY flight was canceled. Not a cloud in the sky. No wind. No weather across the country. My guess is they canceled the flight because they didn’t have enough people or a mechanical issue. Either way really bad. I checked it at midnight and the 830a flight was on time so I was very surprised when I woke up to see the flight canceled and I’ve been rebooked on a flight… An hour earlier than my originally scheduled one. Of course I missed this earlier flight because AA texted at 4 AM when I was sleeping. I was re routed to Miami, boarded a plane, sat in the heat for 40 minutes, then boarded because of mechanical issues and had to wait another hour before finally getting to New York Ironically, the 430 Phoenix to New York flight landed at the same time I did… I could’ve been sitting at the pool all day vs jumping through hoops. never ever will I again fly American Airlines. No offer of a free drink, maybe a few points on my advantage account nothing… As if nothing happened and they did not inconvenienced me at all. I’m so sick of the dumb crackers that they give us on these flights. It’s really like a budget Airlines these days. A far fall for s once mighty company.

Delayed by over 4 hrs, missed all international connections. Horrible customer service.

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.
