The reduced size overhead compartments were a surprise. They keep getting smaller and smaller while amenities keep getting fewer.

The reduced size overhead compartments were a surprise. They keep getting smaller and smaller while amenities keep getting fewer.

Friendly service. Aircrew was very professional and genuinely positive in attitude and demeanor.

I do not like the policy of paying up to get a seat assignment.

We had a great travel experience under bad circumstances at the last minute.

Flight was very dirty. The magazine was a dirty mess. When asked for a replacement it never came. Poor quality flight attendants.

My seat didn't lean back. Also I think the whole "we know we don't have enough overhead space for a full flight, but we'll try to get as much money as we can before asking people to check their bags for free at the gate" thing is kinda icky.

Planes are too cramped. How far are the airlines going to go before Congress steps in.

I loved having a nonstop flight! Everyone was so helpful and having a wheelchair was the best idea my husband and son thought of and wanted me to have! I have AFIB and the ladies that pushed me were a great blessing! Thank you, American Airlines!!

Airline staff were fantastic. Stop overworking and under paying them

Good service by crew unlike my Delta flight to LA No TV was downer and flying MAX 9

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

Plane was late because of a mechanical malfunction and the food listed as available was not. Flight attendants seem over worked and under paid. They just done seem happy. And that can be seen in their faces.

Waited 3 hours on a plane to de-ice due to manpower issues. Waited another hour and a half once we landed because of a gate issue. Missed my connections. Created. A total of 13 hours of delay.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

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

Like most domestic flights in the US, you are basically on your own with this airline when it comes to food, so be sure to purchase meals and drinks ahead of time or expect to arrive starving and dehydrated (like I was).

You need to be a hacker to get the (Free) WiFi

I guess they don’t serve drinks on planes anymore

The flight was overbooked and the staff at the gate started calling for volunteers to drop out and offering incentives. That delayed the flight

Do not get fooled by the term “Delta One” flat bed! The seats were super narrow. The ottoman for the feet was so narrow that when you recline the seat in flat bed position, you can only fit one foot in the 8” width space. There was only 1 flight attendant for First Class. The breakfast took 2 hours to get served. Instead of offering French Toast, the served bread pudding. The champagne with orange juice or Mimosa tasted terrible. Almost all the movies offered were ridiculously old. For a long flight from San Francisco to NY, it was frustrating! I DO NOT RECOMMEND this flight!!!

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Very uncomfortable seats and seat backs, and I am only 5’9”. Delayed due to crew issues, spent a long time with no ventilation. Teeny overhead bins. Wifi worked well. Arrived safely.

I was delighted that we were able to get on the 4:40 pm flight rather than our original booking at 6:55 pm!! Other than that, the flight was comfortable and landed early😊

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

I liked that we arrived earlier, you could improve your snacks give away

The Palm Springs to Chicago O’Hare was on Time and Palm Springs airport is easier navigate. As our connection was only an approximately 50 minutes, we asked staff for insights for the Chicago airport in terms of transferring into the other terminal from which our flight left, and they were unhelpful. However, the United App was very helpful in terms of notifications and even providing directions. The Chicago to Detroit flight was significantly delayed which we all know does happen. However, there were very few updates or notifications as to why this was happening when we would actually arrive. It took nearly 30 minutes for bags to make it to baggage claim. We arrived nearly 1 hour late on a 40 minute flight.

It was fine. Everything ran on time, crew was great.

Our flight was delayed many times throughout the day. The final delay was about 8 hours. I spent time in line to speak to someone at their understaffed desk, and also spent time waiting online and then chatting with a service rep. None of the United employees were any help at all. I desperately wanted to go get rest and possibly re-book my trip but I was denied any compensation or voucher for a hotel. I was repeatedly told it was not United's fault and therefore they had no compensation to offer. Overall, a cold and callous experience.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

Apart from the delay due to unforeseen circumstances. The leg from sjc to dfw was fine. It was the leg from dfw to orf that we encountered issues mainly due to the flight attendant crew not being friendly. We had two small children and we needed some assistance to warm up milk so the baby would sleep. The crew just didn’t get it and made things very difficult. One made a remark that the baby’s dirty diaper smell was a “gift” to the plane in a rude way. Normally I’d brush that off as a funny comment if the rest of the trip the attendants were helpful or understanding of the difficulty we faced. But that wasn’t the case. We were met with rudeness on the second leg. Whereas on the first leg the crew were so nice and helpful.

Flight From PHX to CVG was on time, very professional staff

Flight was delayed and missed connecting flight. Did not give warning about delay until we showed up at the airport. Not good.

The usual wait at Columbus once you land to get to an open gate (20 minutes) and then the usual 30 minutes for your luggage to appear.

Nothing, flight was supposed to leave at 758 am. My flight didn’t leave until 430 pm. Spent the whole day at the airport.

Everything was very good EXCEPT the food, on a five and a half hour trip. They only gave to us was snacks in first class. They didn't give us pillows or blankets.

It was wonderful upgrading to first. Plane was so cold thou. Crew was great. Wish there was a food option in first for such a long flight. Doesnt matter the time of day. Chintzy.

Do a bit better with n first class offer some real food and pillows

We experienced an involuntary change of schedule. Had 1st class tickets from Fresno to Bonaire, put us in coach from Miami to Bonaire a few days later - terrible flight, try to get a refreshment , water or a meal and air. We will never be subject to that again. I'd rather fly another airline that honors 1st class. Adding insult to injury AA reimbursed my wife's ticket $106.66 for the change in seating, me nothing. Haven't heard back from Customer Service, don't expect to - it's only online, can't speak with a live person. So the difference between 1st class and coach for that portion of the flight is only $106.66? Really? I've flown Delta and United on the same route, will go back to one of them again.

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 .
