Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Terrible flight Delayed for over an hour without a reason Told all over head storage was full. It was not. Made to check our bags. What a terrible experience. Fly American.

Older plane and it came with Fleas and flea bites!

My seat was moved closer to the front of the cabin since I had requested wheelchair assistance to the gate.

Rough day of travel all the way around. Wrong info given to us multiple times and mistakes in their booking making our trip 10 hours longer than planned. I’m bummed because I fly Delta all the time and love them. Mistakes happen. Just bummed that this was a rare trip our whole family was traveling together.

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

All good on Delta's part. Passengers could be a little more courteous to each other.

Screen didn’t play movies, do I was pretty boated the entire flight.

Inconsiderate staff, plane was very hot, poor decision-making from the crew.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

East Lounge in Denver was terrible. Turning away active military on orders? Really? Sad.

The flight was delayed, but other than that everything was fine.

Two hour flight delay, it was awful and loss of sleep.

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.

Generally good but there wasn’t any staff available when my luggage didn’t appear at baggage claim in Fresno. It took about half an hour to locate a staff member to open up the locked room where it was being kept.

Flight delayed from Cape Town to Washington then got diverted to miami and in miami we had to fend for ourselves , im still trying to get to Shreveport now

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

Too many fees (but that seems to apply to all airlines nowadays)

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.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

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

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.

Terrible. I didn’t fly and I had an important meeting the next day.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

The flight was great until towards the end when the flight attendant read an excessively long commercial for purchasing an american airlines credit card. The worst part is that we are doing a lot of traveling this year so i was actually interested in getting the credit card, but I was so annoyed with the long commercial that I completely dismissed the flight attendant bringing around the information. Next time, keep the sales pitch to 10 seconds and then pass around the brochures!!

Nice aircraft. Plane was PACKED full and distance between seats was tight. Had it been more than a two hour flight it would not have been tolerable. I had much more knee space on the JetBlue flight I went out on.

New ridiculous policy by american destroyed my allegiance to american. As a million miler with american, I expected it would be easy to get on an earlier flight when I got to airport earlier than expected, and save a five hour layover. WRONG. The online app would not let me switch flights, So I called, and was promised a call back in 90 minutes. HAH! The customer service desk at DCA said “we no longer have access to changing a flight on our screens. If the app couldn’t do it, I should send a letter to American, but there’s nothing else possible!”

I am tired of being nickel and dimed for seat location, checked luggage and carry on bags. That is why i rarely fly anymore.

It was right on time and crew were very courteous

Great flight. Boarding was efficient and quick. On time departure and smooth flight. Flight arrived early at destination. Good experience.

The worse experience ever from flight delays customer service and professionalism.

Spirit's website on mobile did not work. Check-in kiosk would not allow us to check in at 12:09 for a 12:52 departure. Went to front desk, they said we had missed our flight and there was nothing they could do, would not offer a refund, and we're extremely rude and condescending. They said if we had checked in at 12:07 they could have given us our boarding pass. We spent $650 to take a different flight on Southwestern. When we got to the gate and sat down at 12:25, Spirit had delayed their departure time for our original flight to 1:54. I've never been more irritated while flying. I will never book another flight through Spirit again.

We were delayed departing and also it took 40 min before we were able to exit the plane after landing and there was no AC I felt like I’m going to die

My flight was cancelled an hour before take off time.

They charge you for everything. Even water. They accepted my dog as a service dog in my reservation. Then they asked for a DOT form that was impossible to provide. I had to pay $175 for my service to fly with me, that would protect me from death if I ate peanuts. They did not however, serve peanuts on the plane.

Everything was on time. Several passengers were rude/impatient when deplaneing at both FLL and PNS - but this is our society today w/ no common courtesy.

Checking one bag in after we already got our boarding passes and tag for the bag was ridiculous. Only two agents working the counter. It took forever! Second, the all male flight attendant staff was rude by yelling at those of us on the plane, being short with flyers, and speaking so fast that it was hard to understand what they were saying.

Terrible they delayed our flight then when we got on they had to fix the plane then finally we left hours later and when we got there since they had screwed up everything else we had to wait for a walkway so we had to sit on the plane and they turned off the AC and it was fuckin hot

Terrible airline. Cancelled the flight less than 24 hours before the flight. Caused me extra expenses!!! This will be the last time me and my family will travel with them

Very long delay of 6hrs with poor communication from airline. Another 5 pm flight to Miami left on time even though ours was scheduled to leave before that at 3. Would only fly Spirit when you have flexibility for cancellations or delays

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Gate agent for Frontier in Sioux Falls was horrible. Some people shouldn't have jobs where they need to work with people. This person tried to control everything and even argued with a Sheriff's Deputy. He seemed to write the law and think he was immune to everything and could do whatever he wanted. What a miserable experience for a lot of people. He even delayed the flight just for on his own actions. The pilots made up the time lost, but why does this person have this job. Apparently nobody cares at Frontier. We do, My wife said she would never fly on Frontier again.

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.
