Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

Michael, our FA was very attentive, even finding me a chocolate brownie from economy class when the dessert selections were all dairy based. ( intolerant, not allergic so don’t usually need to order dairy free)

I had a bad experience with the security at IAH and felt like a sardine on all 4 legs of my journey.

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.

Bigger seats. Board back to front! Disembark front to back!

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.

They switched my flight to Spirit, Never using Kayak again,

i was denied boarding, even though i had an assigned seat, checked in on line and was at airport early. Then they refused to fully refund the the fair and replacement fair because they claimed it was "no show/denied boarding". I will never fly this airline again

I was not permitted on my flight and had to purchase another flight ticket to Las Vegas.

This was a full flight and I was in Zone 1, however upon boarding, several other zones went in ahead of me, leaving no overhead cabin space near my seat. This created a challenging disembarkment process.

Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.

Flight was delayed 3 times, would have been nice to have received text message instead of email notifications. Frontier app wasn’t even updated accordingly, no gate number disclosed. No agent at front desk of gate to inform of delay. Very confused and left if the dark

It was a no frills flight. Would have liked to be able to charge my device

The flight itself was ok and the pilot was very communicative. However, our flight was delayed for almost 3 hours, the gate was changed 3 times and there was no communication as we were waiting. The flight staff was overall a little crabby...I understand as they probably had a long day but we all did.

Asked for a seat change to be w my wife at the gate they were great in sorting it out to make it happen

Everything went as planned. Crew was great. Seats were still not that comfortable.
