I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

They did a fine job. Can't wait to use Delta in the future.

Seat back monitors and outlets were dead and not working.

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Boarding super slow with people allowed to linger in aisles

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

First time travel in economy and the worst experience I ever had ! Shame on paying 600 dollars to be in a tuna can ! Service was terrible no even water no even class no even matters your flight attendants were lazy and sloppy very bad experience! After all these years traveling in first and once I try this cause I need to go to a destination for an emergency wow shame on you !

Terrible. Flight was cancelled due to the weather in the east and sout east(florida). Did not get any compesation of any kind. According to them, it was not under their control so I lost all the money paid for the 2 fairs from Raleigh, NC to Orlando, Fl.

There were multiple delays but JetBlue tried to make the boarding and departure process as quick and efficient as possible. The crew was as detached from reality as could be, meaning: not very friendly and just doing things by the numbers.

40 minute delay before take off after boarding flight. Bright lights throughout night flight due Issues with light panels. In flight Entertainment nonfunctional

Another horrible Jet Blue experience. This airline has suffered the biggest decline of all from best to worst. TVs didn’t work (again). internet was temperamental. Boarded late and couldn’t get organized to serve snacks.

I hate their constant delays! It’s as if I cannot confidently make plans for timing when I'm traveling with them. I slept through it, so all I can say is it was good.

Did not wait long for wheelchair and attendant to arrive after checking in. Wheeled down to plane Was greeted with a smile when entering the plane Choice of snacks was very limited to 2 items. Seats are uncomfortable. My butt was sore after the 1st hour of flying. Needs better cushioning at seats.

One hour delayed departure resulted in problems with planned ground transportation at my destination.

No WiFi No TV Bag of chips I guess it could be worse.

I really liked the way snacks and drinks were available throughout the flight!!! The flight attendants were also all fantastic!

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

Same basket of unhealthy prepackaged snacks (junk food) which was depleted by the time it got to my row!!

We experience delays on departure and connecting flights resulting in 14 hour to our next departure. We were accommodated with a night's stay but was only provided a 12 dollar meals accommodation. The airlines rules state.at least 50 dollars. In any case, it can not make up for the whole day missed on our vacation in Sydney Australia.

Flight from PHL to PHX arrived 50 minutes early and a gate was available. First class flight attendant Stephanie was very friendly and polite. Sanitizing wipes should be provided with meals in addition to refresher towels.

flight delayed so missed connection and this had to rebook for next day

Flight departed PHL one hour late due to late arrival of aircraft. On board services were okay. First class menu does not offer any new items; same desserts (cheese & crackers or Mango sorbet). At least there were no credit card promotions during the flight.

After sitting on plane for 7+ hours, flight was canceled. And to makes matters worse, my suitcase is in baggage hell!

Terrible Ticketing and Check in process. I learned that AA unilaterally cancelled my premium seating from PHL to CLT and from CLT to JAN. They did, however, refund my money, but my seating was subsequently severely downgraded. They didn’t have a seat for my unless I paid for it! Not cool! Consequently, Check-in took 45 min. AA is usually great, but this was my worst experience with AA ever. Appalling they they arbitrarily cancel my seats threatening loss of flight if I didn’t pay for a seat!!!! -John

We liked quick boarding and on time departure. Seats were very uncomfortable.

Terrible… missed our flight due to ridiculously long time to go thru baggage check-in!

Everything was really good but the seats are not very comfortable.

Spirit canceled the flight in March and never notified me!

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

The weight limit per bag was really low - 40 lbs - so we had to pay extra. Then, they said their carry on size was 14x18x8, and we measured our bag very carefully. It was within the limit, yet they said it was too big, so we ended up paying an extra $100 for that too!! So it wasn’t the cheap flight we thought it would be. Then, they moved up our initial flight to depart 3 hours earlier which meant we had to be out on the road by 7 am and then have a 6 hour layover and we got home at 2am. It was a grueling day. I won’t be flying with them again.

Overall it was a good experience. Stewards were very kind and professional. The departure and arrival times were as promised. Plane was clean.

Terrible as usual!!!! Very unprofessional and rude flight attendants! You get what you pay for! HORRIBLE

My experience was above excellent!!!! First the lady that pushed me in the wheelchair to the gate was outstanding!!! Then the ladies at the gate went over and beyond, by helping me fill out the immigration form! I would not have been able to get to Guatemala without their help!!! God bless them all! They were amazing 🙏❤️🙏

First....my trip was from Ft. Myers to Philly (not the other way around). Plane was clean, staff was friendly and flight was efficient with boarding and flight time. Thumbs up all around.

Six hour delay. Poor customer service. No voucher. Bad communication. Missed important appointments.

I purchased a carry on bag online…was supposed to cost $72 but after a whole slew of bs charges, the total was over $175.00. Because of these hidden charges, I will not even consider flying Frontier ever again. It’s just not worth the hassle. I’m scratching this company off my list forever.

Flight delayed 3 times, resulting in late arrival, rental car place gave car away resulting in increased BS charges because I was late. Frontier blows.

It was impossible to change a carry-on for a checked bag after the initial selection. The flight was delayed 14 hours "to allow for a late arriving aircraft." The seats were shockingly uncomfortable. This was only the second time I've seen seats that didn't recline in an airline. The first was in an East Bloc airline before the fall if the Iron Curtain.

First time flying Frontier, I am not sure the Ala Carte menu of options is for me.

I liked getting off the plane. Everything else was well below standards. Not even offering a bag of peanuts for free for a 4 hours flight is ridiculous.

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.

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..

Flying frontier reminded me of flying with my family in the 80’s in all of the worst ways possible. From poor customer service to little to no technology. The plane was dirty old and also stuck in the 80’s. From their seatbelts to not having anywhere to charge our phones the seats and the equipment I wasn’t sure if I was being punked or thrown back in time. Needless to say I don’t see myself flying frontier ever again.

Everything was on time and smoothly run. All employees appeared happy and enjoying their job. The delay in take-off was unrelated to anything in Frontier’s control. I wish there were a caffeine-fee, sugar free soda drink option besides water. There are multiple zero sugar caffeine free options.
