Food was hood for airline food with good poftion and variety in meals. Frequency of beverage service was very low and amount of soda with meals was inadequate.

bad… no veg food was provided eventhough i pre ordered special meal

Excellent service provided the flight crew. Food and drinks were very good.

Meal options for vegetarians can be provided… Nothing was offered for me for dinner.. crew just said no vegetarian option available and did even bother to provide any alternatives or something to eat.

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~

I was really impressed with the experience it was my first trip overseas. Nice staff

Not enough food for everyone. . Always run out of food when we ask

The crews were smiling all the time with soft tunes when they spoke; the food was excellent. Thank you!

They charged me $900 to board my flight I already paid for just because I missed my previous flight. I do not recommend this airline by any means.

Not good. Small seats. Not enough food that customers wanted. No special requests were given that i could see. Slow response from flight attendants

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

late departure due to some unspecified issue with ventilating the cabin. They got it running but it was FREEZING for the whole flight. I asked for a blanket but they didn't provide one. They could not turn up the heat. it was quite miserable.

I still prefer Delta, but Delta doesn’t fly to State College PA.

Everything was fantastic. Modern plane. All the amenities! Although the paid snacks and meals are pure robbery. Like i understand airlines need to make money, but 11$ USD for an overnight oats with some nuts in it and barely any pieces of apple.... Highway robbery

The flight was bumpy. No Breakfast or coffee was served, not even a bottle of water. The food was okay but odd. Rice with peas instead of couscous with some unknown green thing. United Airlines did not tell me that there was VERY LIMITED HANDICAP SERVICE IN NAPLES. De-plane via 20 aluminum steps. Taken to Van. You must walk into the terminal, find luggage, and then walk out to the rental car pickup spot that is 1 block from the terminal.

Crew did their best but the plane configuration is too tight if you're bigger than an average sardine. Controls for the entertainment system didn't all work. The aircraft hadn't been cleaned in awhile.

Didn't make it dir to delays - no support from United staff

My flight was delayed for a whole day, so I lost a day of my vacation.

flight delayed, was put on another flight after standby queue, luggage was misplaced and arrived to me 3 days later

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

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 flight was delayed till next day ! They kept delaying every 30 minutes then after 3 hours they delayed it till next day. We kept waiting in line standing more than an hour to get the hotel and meal vouchers. There was no communication at all. Everything was bad

Smoothe flight. Pilot and crew did a great job. Uncomfortable seat in this jet, felt worn out

seats were way too small. Too short of a flight to offer amenities.

The main problem was delay. The plane was at the gate early and bags were loaded. However, there was no crew for the flight. They were inbound from LGA and had to land and make their way to our gate. It took more than 40 minutes. Then, once the crew arrived and boarded, one of the crew members had to deplane and then a replacement crew member had to be found. It took another 40 minutes or so to get the final crew member. In all, we took off about 2 hours later than our scheduled departure time. Once in the air, the flight was great. Smooth most of the way. The crew was professional and efficient.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

American is a steady for me. I always get what I expect from them. Sincere effort to get me from one place to another.

Average, boarding was ok, the eye scanner broken mid way through boarding they ahd to do it manually. Did not eat any food, Not even water was offered for free.

Boarding attendant was rude. Crew on the plan were more interested in talking amongst themselves and did not ask parentage if they needed anything or even walk down the isles.

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

I upgraded my ticket at the ticket counter and was not informed of the huge bottleneck at TSA pre check. It took me over an hour to get through the line at this small airport and although I ran to the gate and reached it prior to scheduled departure, it had already pushed pack. I missed the flight. Spirit rebooked me on a flight to Orlando that evening, which would require me to then rent a car and drive to FLL. For scheduling reasons, I determined it be would better to rent a car in Pensacola and drive it to my destination in FLL. Spirit called me that evening and asked me if I was going to board the plane. I explained no, for scheduling reasons. The person apologized and said I would receive a refund, but I have not heard back. Certainly, I ought to be refunded the upgrade I paid for at the counter.

The staff from LAX to New Orleans were rude but the staff from New Orleans to LAX were nice!

Did what they needed to do. Brought us from point A to point B timely and without issue. Boarding through deplaning smooth.

Direct 2.5 hour flight good. Free snacks and coffee, water, or soft drinks not available...bad.

Atlanta airport gate area floor and nearly all seats disgusting. Spirit airlines crew fantastic!!

Over 2 hour delay due to “weather” but all other flights were taking off with no issues. We felt lied to the entire time as well.

Everything was excellent and as expected. The boarding process was great but deboarding was a bit slow. No fault of the crew; it just seemed like the passengers didn’t want to leave! 😂

Booked direct in July '24. Turned into a 14 hr layover (both ways) in Denver. My 5 day vaca turned into a 1 day . Not good, BUT,... Thank you for the people @ Frontier who were professionally friendly & approachable.

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

The crew was ghetto lol I felt like I was on an inner city field trip

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

There was nothing to like, flight delayed had to move to different departure areas, disorganized to say the leasr

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.
