Flight was 3 hours late so only had an OK experience

It was very cold because the air conditioner was on high power, and my son got sick.

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.

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.

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

I had a great flight. Everything went smoothly and the flight arrived early.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

This flight was awful all around. Delays on the tarmac at PHL before takeoff and at the tarmac in Chicago caused me to miss my final connection. This was completely avoidable, in my opinion.

Internet service was erratic. Crew service was poor and slow. My luggage on this non-stop flight was lost and not recovered

The CX617 from HK to BKK was delayed more than 1.5 hours.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

Average - flew with Jet Blue internal and it was far more comfortable and better food and entertainment. Notable difference

The flight got canceled due to mechanical issues, and he to be rebooked and missed my appointments for that day

The flight was scheduled to depart DCA at 12:30 pm but was delayed twice on the ground so that we were finally scheduled to depart at around 4:00 pm. Once we boarded, it was announced that takeoff would be delayed again to fix a hydraulic problem which delayed our eventual takeoff until around 5:00 pm. Once we departed, it was a smooth flight back to ORD. We did not get any explanation about what caused the original significant delay. In my experience, this happens frequently with AA.

Flight got diwngraded last minute and left us stranded. I was told I’ll be given credit for my luggage and seat upgrades but haven’t got anything yet

Crew was nice, explained emergency protocol very well. Flight took off and arrived on time. Pilot explained the small delay that occurred with docking and providing updates. I would definitely fly spirit again.

The seat are terrible. Don’t even think of sleeping on a Spirit flight. The kids that run the plane aka flight attendants are pretty rude and straight forward. They get the job done but without class.

I had a death in my family and booked my flight on Spirit. My flight was cancelled the morning of my flight, no explanation, no help to rebook, nobody to talk to. The next available flight was 2days later !!!! Terrible airline, will NEVER fly with them again!

They took a horrible route with a lot of turbulence and I eneded up getting sick. Even if the flight takes longer. Don't put people life at risk just to get to the airport on time.

Every thing was fine ,low price,easy on time ,clean, good staff, really no issues

Had to board plan 2x due to lack of security check after 1st boarding

Miserable. The crew was rude, the flight was delayed 5 hours for mechanical reasons and then “weather” even though other planes were leaving.

They kept Changing the flight times. It was delayed several times and at one point it was supposed to depart at 3.40am! At which point we ended up staying overnight and booked long a separate United flight for early morning departure. The spirit flight then got moved up and left at 1.30 in the morning when it was supposed to leave at 9.40pm the night before.

Flight was delayed...not horribly late. Just before push back engine shut down for a quick replacement item that took about five minutes. After that, everything was smooth and the pilot was able to make up time in the air so that our arrival time was not too far off the original anticipated arrival time.

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

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

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!

Fecal matter in seat back pocket. Presumably from a kids diaper.

I didn't get to do this flight l, hard to review

Not good 😐 Over priced baggage fees Small hard seats No wifi or entertainment options 😕

Left Denver late, then sat on tarmac 30 min after arrival

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.

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..

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.
