Flight crew issues delayed my flight by 2 1/2 hours. Causing me to miss my connection.

Boarding was efficient and smooth. Departure time was on time. Arrival to Detroit was early. Average food . Average crew service Very average cabin comfort. Nothing spectacular one way ir another, except for the excellent on time performance.

Flight was delayed. No information on why it was delayed. After we boarded the flight, , the crew made announcement that the captain hs not arrived and he will take 15 mins more to arrive. Passengers were just sitting patiently for the captain to arrive and start, Terrible experience.

This was my first time flying Delta ever and I had a great experience!

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Outdated equipment in disrepair, wifi inoperable.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!!!

We arrived 25 minutes early only to be told our gate was occupied and so we sat for close to 30 minutes to pull into a gate. That’s not an early arrival!

Experience was great. The best part is the free Wi-Fi connection which helps me to work on the flight

The gate agent had a really bad attitude and refused to help me get on the standby list. She just handed me a card and said I needed to call a number. I asked her to help with the AA app on my phone and she just shrugged and said she didnt know. After a few phone calls, I eventually just went to a different gate agent on the other side of the terminal and got the help I needed.

The TSA check in took 1.5 hours to get through in Austin and I missed my flights back to DC

As previously stated the delay I experienced flying from Wichita to Chicago caused a host of issues. When I finally was able to be booked on the last remaining American flight from Chicago to Cincinnati, the gate changed four times with the last change occurring very near the scheduled boarding time. While I didn't have a problem moving from gate to gate, I did notice and make note of others that had mobility issues and had to move each time for the gate change.

Overall, my last three trips on American Airlines have all been either delayed or "rescheduled" due to mechanical issues. At least on delay caused me to miss two possible connecting flights each later than the first. My last option for my last connection required the assistance of the onsite service desk (O'Hare Airport). The wait time for the service desk was such that it jeopardized getting booked on the last connecting flight available for the night. Suffice it to say, my latest experiences with American Airlines have caused me extensive loss of productive business and personal time and can therefore be classified as significantly less than satisfactory.

There was free WiFi (definitely a plus), but the flight was delayed 45 minutes waiting on a catering truck that never arrived. The pilot said there would be food vouchers given out at the end of the gangway to make up for the inconvenience, but there was no one offering those. Delay made me late for work!

Waiting for gate in RDU for more than 20mins is crazy.

Flight was on time and there was an empty seat next to me. That makes for a good flight!

Maintenance took a very long time and then we were in a holding pattern. While a one-off maintenance issue is standard, there were delays on both of my flights for this trip based on maintenance issues with the planes, which delayed both flights over 45 minutes. Thankfully, I didn't have any connections but it wasn't an experience that would make me pick AA if I have other options.

The flight from Boston to San Juan was boring since you guys don’t offer wings if during the flight. The returning flight was better offering WiFi to passengers. The food was horrible not enough on stock.serve paying customers better.

Delay at the gate without any communication such as announcement, sign, monitor, email or text. Found out later we were boarded with the knowledge of a significant delay, awaiting communication from Europe. Pilot was the only source of information regarding the delay after a long gate delay and sitting for more than 30 minutes after boarding. More than 2 hour delay, landing at 2 AM. Offered to deplane and reboard, but probably should have just waited rather than repeat the process. Not the first time experiencing the lack of communication with Spirit airlines. This morning was not as bad as showing up to a terminal without an agent (or aircraft) without any sort of communication. Much later an email was sent that stated our flight was rescheduled for a week later. Situations do arise, but simple communication can alleviate a lot of the frustration. Hard to believe a corporation doesn't understand that. But, you get what you pay for...

No complaints with pricing so don’t expect a lot of extras.

Forgot my anxiety pills, crew didn’t knew what to do then few minutes after they gave me a bottle of water and told me to walk thru the hall. They should be trained for this kinds of situations cause it really would help someone. Tips: bottle of water (airports should allow passengers at least having them thru) for this kinds of situations. Alcohol wipes just in case they don’t have. Tap water on skin (preferably little cold or a normal temperature) this will help.

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

Our outgoing flight was cancelled two hours before boarding and Spirit was not able to get us onto another flight. Their customer service was slow and unhelpful.

Terrible. I never made my trip to Puerto Rico and my layover flight from IAH to MCO was delayed over 3 hours and made me miss my connecting flight. I spend 2 days in an airport just to have to go back to Houston. This was a trip for my birthday and I lost money on this trip. I understand the situation with Venezuela affected flights but it’s always something with Spirit.

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

Every Spirit flight we took was delayed by nearly 2 hours. We arrived in MCO and learned that our connection had been canceled. There were no options for rebooking for 4 days. No hotel vouchers provided, no transportation etc. The airline essentially stranded us, and rhe passengers from 6 other flights hours from our destinations with no assistance. Still no word on my refund. Terrible customer service.
