Flight to Tampa was delayed taking off due to plane arriving late but no other issues

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.

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.

No Snacks or Entertainment. The flight was short, snacks should still be given.

See prior comment about how Kayak mishandled my reservation and delayed my arrival by 6 hours.

Boarding delayed 20 minutes for no reason, no wifi, in flight entertainment, or snacks / waters?

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.

The aircraft had several problems - from excess fuel to non operational ac. Two hours of delay in Chicago could have been avoided with proper planning and aircraft maintenance.

Crew in Columbia was not prepared for landing. It was a bit of a disaster and getting bags took forever.

The seats from lax to DFW was so tight that I could not move my legs . No WiFi and had to pay . Not a good selection of entertainment
