The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.

The wait in the tunnel to enter the plane was too long. The counter personnel, specially ''Israel'' was really not welcoming considering Delta Standards. Other than this everything was good overall.
an he late. super rude gate agent, to every person. spoke down at people.
This a short easy flight. No food or drink but that was not an issue since we were only in the air for 35 minutes.
No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?
Connection flights should be spaced out farther because too close I missed my connection.
The flight was way too HOT! And the plane did not have any in-flight TV entertainment.
The gate attendants and the crew were terrible. Because of high winds, they needed to carry more fuel, so they had to get volunteers to take the next flight at 6 am the next day. They did a terrible job of it - our flight ended up taking off just under 3 hours of the scheduled time. I hope to never fly Delta again.
Great service. Great staff. Boarding was a little slow, but I think there was a service dog slowing things down.
We splurged and decided to fly first class. Seats were roomy. But flight crew arrived late to the airport. That delayed our flight. Most of the passengers had to try to make connections flights. I felt bad for them. We checked 4 bags. We got three from the baggage claim carousel. 4th one was lost. Delta online help wasn’t good. Baggage claim staff were sympathetic and nice but we waited around for almost 2 hours and it had t been found. They did find it several hours later and we had to drive back to airport to retrieve it. I won’t be splurging on 1st. Lass again anytime soon. I think we got worse service. I am also not a huge fan of delta but we have family in ATL so we don’t have a ton of choice. What should have been an easy flight turned into a stressful event due to flight crew tardiness and baggage mishandling.
My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers
The flight was delayed several times as they didn't have pilots. Then we were boarded on the plane and again waited on the tarmac for over 30-40 minutes waiting for pilots to board. The in flight entertainment was confusing at best on how to use it. It took multiple attempts to get wifi to connect and by the time it worked the flight was almost over.
It was a late flight; crew was invisible. Zero air flow - the tiny plane was a sauna; the left the lights on for 1/2 of the flight; there was no water. Never again.
What an amazing plane! We flew a 787 to Miami. Although the Internet was not functioning, it was a wonderful flight.
Plane was in good shape, multiple passes from the drink cart, and one of the smoothest flights I've had in a while.
Smell of jet fuel was overwhelming from inside the plane while on the ground at take off and landing. Gave me a sore throat and a headache. During boarding, de-planing, taxi-ing, waiting in line for take off, etc. Also, the vents didn't have enough cool air coming out (yes, off course I opened it all the way) so the whole flight was hot and stuffy. But just my vent - all the vents.
After lack of help in Philadelpha made us late to board our flight to akansas City, our flight to Kansas City was very good. And the flight attendants were also very good. The only thing that sucked was problems with assistance in Philadelphia caused our bags not to arrive.
AA needs to review it's policy whereby it's most tenured staff gets to pick their flights. This tends to place flight attendants with the most jaded customer service attitudes on long haul flights. Whilst I realize this is a generality I have experienced increasing levels of woefully poor customer service. One particular flight attendant on this flight was downright rude to several customers. After serving an awful meal they disappeared to their cots below deck and for the most part did not reappear until 1.5hrs before landing. A very disappointing flight.
Legroom was decent, but the seat comfort was horrible; I believe the seat cushions have lost their cushion. I was uncomfortable and had back pain throughout the nearly five-hour flight. WiFi did not work despite my attempts to get it up and running. This was very frustrating as passengers all around me were streaming football games, movies, and accessing email and text messages. One flight attendant suggested it was my seat, but that makes no sense, given WiFi doesn't work that way. On another note, I rarely have a good experience with aainflight.com.
Delayed delayed. Poor professionalism. Our seats changed and we pay for them
The airline schedule services was simply mediocre. The ground crew is fine; they are doing their best. The after-delay services were simply poor, and after-cancelling services were almost non-existence. Receiving refund is one rescuing point, but please keep in mind that, people wants to get home or get to their destinations. Cancelling without aftermath recourse is simply poor services. AA needs to fire the marketing department, and the customer-service related leaders.
Maximizing profits is one way to a healthy bottom line, the other is repeat business and referrals from satisfied customers. Frontier has clearly chosen the former. One of many examples: Family emergency required me to cut trip short. Headed to the airport to fly standby for the return trip I had already paid for (yes I understand prices vary with demand etc). Was told there is no standby and that I would need to pay for, despite what it's called by the company, what amounts to a new ticket. And surprise surprise, there turned out to be dozens of empty seats on that flight. To say nothing of the sleazy third and fourth party resellers, the flight/ticket insurance I elected and thought I had paid for that mysteriously wasn't there when I needed it before I left, and on and on with third world sleazy management decisions. The inflight coffee (that I had to pay for) was very good though.
Flight delayed and missed connection. Next available flight was a 10 hour delay.
Great flight, no problems. I wish they would increase the checked bag weight limit. Packing was very stressful.
First of all we hade waited 3 hours in the airplane waiting to leave. Second the return schedule was changed and it messed up my entire vaction. I won't buy never again another flight and recommend to nobody traveling with them.
I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.
Terrible. Flight cancelled with no reasoning and no flights to rebook. Employees were useless and did nothing to help. Did not even know where to retrieve luggage from the cancelled flight. Flyers beware.
sluggish boarding and arrival procedures, fake nice flight attendants, and lots of delays.
You get what you pay for nothing essentially but a hard uncomfortable seat that doesn’t recline and kids screaming all around you and chaotic boarding and limited check bag weight allowance when compared to other airlines
Not very good. Paid in excess of $400 for assigned seating for my family and that was not provided. I want that money back.
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!
