Missed the flight because of them and up geting a rental car

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

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

Was as expected. Good leg room on planes - much appreciated.

Fight crew was not very attentive and the bastions were gross!

I don’t think the flight attendants are happy. They do not seem to be friendly or welcoming.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.
