3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

3 hours late and all they have is was a $12 meal voucher. That’s not even enough to cover fast food.

Among the poorest flights I’ve had with Delta in a while. Entertainment system failed completely on a 7.5 hr flight. Crew seemed distracted and not the normal friendly crew. Flight overbooked it seemed… very crowded.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Really bad baggage handling. Had my Rimowa bag badly damaged at the latches.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there

It was good until there was a 3 hour delay because there was not any pilots to fly the plane.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Ongoing flight was delayed. Staff at bag recheck was able to get us on an earlier flight. With only 20 minutes till take off we feared our bags would not make the new earlier flight. We were most delighted that they did and were there when we landed. Delta came through

Friendly flight attendants. Comfort plus seats were very comfortable and had lots of leg room. 10A and 10 B.

Great! I love Jet Blue. My favorite airline! Very efficient, clean and timely.

We were told that our flight would be delayed for 90+ minutes because of weather, so we went to get something to eat only to have them randomly start boarding 15 minutes after the announcement, with no warning.

Entertainment... No earphones passed out. Many including me couldn't use the TV. Legroom was good. Crew was indifferent and a bit surly. Free wifi was a nice convenience. Check in desk location was unknown. Gate number on the boarding passes was wrong.

Confusing. Delay updates were out of whack At one point it said my flight was 25 hours. Three gate changes and two delays only to change back to original departure time. Gate announcer and on board flight attendant (Alejandro) making the announcements was impossible to understand due to accent and speed of speech. After beverage service the rear flight attendants sat back there on their phones. No refills no checking in, one sweep through for trash collection. Very impersonal. Bring back Coke products

Business class is great. New airplane, very comfortable, better than some of the major airlines I am used to

Delayed by almost an hour - I also noticed that all JetBlue flights departing from PBI were delayed yet the weather was perfect.

Non operational toilet, non operational charging outlets and my air didn’t work.

I loved the wifi, much better than Delta. Seats were old. and bathrooms dingy.

There was no wheelchair or wheelchair escort at the gate..unacceptable

Delayed 4 hours because of maintenance issue they knew about all day. Get another plane. Time is precious!

The entertainment wasn’t playing in the app or online.

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

It is a modern tragedy that any airline expects you to travel for 14 hours in such discomfort and that the only way to add comfort is exorbitant prices. I was in pain by the time we landed. Shameful.

Original plane sidelined. Had to wait an hour for replacement.

Crew was very cooperative and professional. Passenger's first checked in bag should be free.

No real agent onsite helping you for missing luggage there. Not like the other airline next to UA desk, they have staff attending in their desk assisting answer/helping luggage issue, even after midnight.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

They have trouble to keep their flights in schedule. Seems not having enough staff to provide appropriate customer service. Lacking real agents on site to help customers. Have to use QR code/web site/call to be able to talk to real person can help you - and you may have to punch though series of options first, then hold until someone assist you. Similar for baggage claim, no real agent onsite helping if you missing luggage, not like other airline next to UA desk having staff there even after midnight to assist customers.

United is my favorite and I always try to fly United. I feel like this crew didn’t mesh well together.

Our flight was delayed three times. It took us 17 hours to get home.

Worst airline experience ever. Lost my IPad going thru security. Charged for my dog carriage at the gate not at ticket counter. Gave away my seat 6D. Expressed I wanted my seat back after charging me 99 for dog carriage. Should have thrown it out. Had a 16 yr old Yorkie heading to Boston after being a snowbird. Seats small. Very bad experience. Still don’t have my IPad. Horrible

Flight delayed then canceled! I will NEVER fly Spirit Airlines again and will tell all my friends!

The flight was fine. The itinerary change from original booking was not good. We were originally leaving at 12:50 pm. The change to 8:29pm put us getting home in the early morning hours the next day. Then having to wait over an hour on the ground for a parking place to get off the plane was exhausting.

Delayed..4 times...completely disorganized boarding. After 5 hours they scrambled to move ppl off plane bc they overbooked. Then they didn't have a cabin crew. WiFi on plane didn't work. Zero amenities. Once we boarded we sat on tarmac for an hour. Explore all alternate options including purchasing a pair of hiking boots and walking to your destination instead of flying spirit.

The seat was very uncomfortable from Boston to Nashville. Otherwise the flight was excellent.

Our flight was delayed two hours. We nearly missed our connecting flight and had to rush across the airport with little kids and all their luggage. They didn’t give us enough time to walk from one gate to the other, then when we got on, we waited another half hour while the crew loaded cargo. It seems like they could have given passengers more time if they had cargo to load anyway.

I had a phobia for Spirit and now is 100% confirmed. Flight delayed, missed connecting flight and staying overnight . Now not even able to get my boarding pass until I’ll get into the airport. It’s really really bad at this point

the landing was terrible. the plane touched down and had take off. the plane flew around and landed a second time.i understand the weather might of been the problem. It was a scary experience and no explanation from the captain.

Service was awesome 👍🙏 thank you Spirit Airlines...love the Big Seat...😎

Crew was very engaging and welcoming. Seat very uncomfortable and inadequate leg room made the trip a long 3 hours.

Did not realize seats did not recline. Best to travel in an exit row... No question

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

When we arrived we lasted 48 minutes to be able to get off the plane without air and the plane turned off more than half of the passengers because after they started to leave they realized that the bridge was defective

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

I appreciated the upgrade to free cary-on bag and seat selection at no charge

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.

Didn't like anything..entire crew was very rude to everyone on the flight. Plane old and the trays fall down on you the while time you're flying. Charged more for a carry on bag than for the plane ticket itself. Did make it from point a to point b, but worth the extra money to fly with another airline
