I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Paid for premium extra leg room but the bin space for rows 1-3 had to go in rows 4-6 and 4-6 had to go to 7-9 because flight attendants have snacks and their luggage upfront. So we pay extra to have to fight thru traffic to get our bags. Only 2nd day of new seating so hope they fix this.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled. No snack or drink on this flight.

WIFI was great. My selection for seating is an aisle, but during my trip, I never had an aisle seat. If we can get that corrected, I will be thrilled.

The wifi on the plane is great. The only issue that I have is that I prefer an aisle seat and on my trips this week, I was either in the middle or window. If we can work to secure aisle seating, I will be thrilled. Nice trip.

All good except once again bags took an hour at Midway Airport Happens all the time. Ridiculous

Everything went smoothly and we even arrived a little bit early.

Great vacation. Can't wait till next year for another one.

Great flight but super high price. Glad it was a business trip and not personal

Very convenient considering that is a non-stop flight, but the Aeromexico still has old model planes, so the entertainment was very poor and the space for carry-on luggage was very limited.

This long-haul international flight was the most comfortable among any of the same kind of flight operated by an American-headquartered airline - second to none!

Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.

My requested wheelchair never appeared. So many entertainment choices yet, I found little of interest and no internet option to search on my own. Both were minor issues.

Inexperienced boarding crew allowed too many bags on to a full flight and delayed takeoff causing a missed connection and unplanned overnight stay. There was a hotel at the airport but Delta would not pay for it offering only to shuttle me to an area hotel. Never even offerred so much as an apology by anyone working for Delta.

I have diamond medallion status and usually we are in comfort plus . We were in main this time ( which was fine ) and my husband wanted wine . I have at least 10 vouchers for drinks that are good for this year and next! The attendant would not take the picture of the voucher as proof and never came back to check as She asked me to pull it up on delta Wi-Fi. Instead my husband just used his Amex to buy the wine . Disappointing!!!

Late delayed flight delays boarding and delays leaving and delays on arrival too. Cramped plane no room no food.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

My experience on any Delta flight is always overshadowed by the time Delta removed me from a flight for no apparent reason.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

The attendant on board was amazing. She should be doing business/first international long haul.

I was fully checked in the prior night and i was unchecked and then didn’t have a seat when I boarded. Instead of an aisle seat, I was out in the middle seat of the very last row of the plane.

In overall it was a good experience, the only down point was that the entertainment screen was working properly.

HORRIBLE, my initial flight was cancelled, they made me pay $200 extra dollars and that got cancelled as well! After 6 cancellations I decided to get a refund because I needed to get home to my babies. Out of $1000+ dollars they offered me only $40 in refund! Totally unacceptable! The flight that they cancelled I was able to fly it on another airline. I had to spend $400 on one way tickets just to get home! I’m still getting the runaround.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

Seated dude next to me even though lots of empty rows. But main thing was we sat on the tarmac after landing for 30 minutes because of, in the words of the dude who sat next to me, “operational incompetence”. We got changing directions about where to pick up gate checked bags. Pilot and flight attendant were awesome though.

It was a pretty standard flight... until the almost hour and a half spent on the taxi way. I get that the weather has been poor but the delay had nothing to do with the weather and more to do with a plane with several issues tying up the gate. I get that that happens from time to time but this has been EVERY flight I've been on for the past 5 years and I fly 3 to 5 times a year. This isn't just United... it's American, it's Delta. It's an issue with the entire industry. I work for UPS and packages on a cargo plane get better service than people do these days. Anymore I HATE flying.

Flight arrived 30 min early and bag was waiting at the baggage pickup. United Club HNL was one of the nicest in the system

Arrived 40 min early which was great - sat in runway for 35 min so no gain. Then waited for luggage 45 min. They need to staff accordingly knowing its one of the busiest week in Phx

My flight got rerouted due to crew rest. I was sent to Dallas customer service was not very polite. Was given a $40 room voucher for Motel 6 and $12 to eat with. It delayed me by a day. Where if I would have just stuck with my original flight Arizona was delayed to Cleveland and I could have made it home. They put me on a 9:00 flight out of Dallas to Cleveland without my knowledge or consent. When originally I was told it would be 8:45 a.m. on February 1st. I told them I could not take the 9:00 flight because I did not have anybody to pick me up from the airport at that time. I'm extremely disappointed in how I was treated. And I will not fly American Airlines again.

I am very appreciative of the help provided to me by Dennis and Whitney. I had lost my phone at EWR airport and they were very kind in assisting me. This included advice on how to file a report and also helping me connect with family. The pilot was also great about keeping passengers updated on the flight progress with regular communications over the system.

Awful. Original flight was delayed 5 hours. Had to to take a connecting flight instead of direct. Had a 4 hour layover. I missed all of my morning meetings getting in 5 hours later than I was supposed to and had to change to take a later flight the next day to get them back in which cia time another $150.

Old equipment, needs upgrade and seat comfort. Internet didn't work 75% or the time.

The screens were inoperable for movies and such, but everything else was just fine

For a 5 1/2 hour flite i considered the "business class" to be subpar. The seats were just ok, no amenities, really nothing more than a long domestic flight. Frankly disappointed.

Delayed an hour due to operational issues. Minimal apologies or care for the significant inconvenience caused. Landed at nearly 1am and they still couldn’t find ground staff to get us off the plane promptly.

This was one of the most frustrating travel experiences I've had to date. I had changed my flight day of to this one as it was slated to depart on time. It ended up being so delayed that my original flight took off before this one did. The boarding process began but eventually stopped and everyone had to get off the plane as a problem was identified. The person at the front desk just tried to laugh it off as if this wasn't already a huge inconvenience. From there, we eventually got to board only to sit at the gate for an additional hour because of some additional issue. This was extremely frustrating and caused a lot of stress.

Update to handle the delay was very bad, crews no smiles or welcome or thanks. Don’t care attitude

All of our flights were canceled, though every other airline was flying out and in

It was smooth sailing snags we had a really smooth landing and a great flight!

Liked early boarding for disabled customers. Seat comfort could have been better, would have appreciated an empty seat between my wife and I since I suffer from arthritis, neuropathy, and spinal stenosis. Also aisle seat armrest was immobile and this made it difficult to get into and out of my seat during the flight

Flight cancelled and no alternative offered for over a week. Ruined our Christmas vacation plans

They canceled the flight at the last minute! No customer service. Unable to get another flight for 3 days!! Spirit was NO help at all!!

They canceled the flight and didn't assist in getting a new flight on any airline. I had to spend 10 hrs in the airport after getting a ticket On Delta for twice as much. I've flown Spirit many times and this was my worst experience I've had.

They cancelled my flight same day with no explanation why. They offered to rebook me but it would not be until 2 days later. I will never use them again.

It’s Spirit need I say more? Thank this little airline because without it the other airlines would raise their prices so much I wouldn’t be able to fly anywhere. It’s affordable and gets you where you need to go! I’m not flying to get a free bag of chips, y’know?

Honestly horrible. The plane on the way back was delayed 6 times with no explanation on why. When I asked for a refund or some money back because I had to miss a day of work because of the desk, they told me no. Because of how poorly it was handled I will most likely never take spirit again

Very positive in both directions. Safe travels, nice staff, lost and found in fact found my phone under my chair! I was out of cash after my NYC trip otherwise I would've offered a reward for helping my day out immensly! Thanks you so much Spirit staff!
