The gate experience at LAX was abysmal (same for the arrival experience two days prior). Despite the LAX -> SAT schedule of two flights daily, our departure gate was at a smaller hub that we had to be bussed to from Terminal 4. Fortunately, I arrived at LAX extra early and had time to spare, but if I had not known, I might have missed my flight. I looked at the LAX airport map in the AA app and there was no indication of the additional boarding process. Lastly the gate area we were bussed to was crowded with limited food and beverage options. On flight, the fight attendant was hospitable and attentive, the flight was smooth, and AA's free (and working) wifi for AA members were all on the positive side.

Our flight from JFK to Madrid was delayed. We had to go from one side of the Madrid airport (Terminal 4s to the far end of terminal 4 - Gate K98) to our gate in less than 30 minutes. Put passport control and security/baggage check and that’s very hard unless you’re Usain Bolt. I called Iberia Airlines and the telephone customer service told me that I was going to have to pay to re-book. Luckily the help desk in the airport (who was dealing with dozens of people from the same JFK-Madrid flight) did not charge us extra to reschedule to a flight 8 hours later. They also gave us a voucher for breakfast and lunch. Glad the actual person at the airport had some actual sense.

Take-off delayed an hour because of a missing flight officer, so,arrived in Charlotte lates causing many passengers to miss connections. Otherwise a very good flight, safe and comfortable, with an excellent professional crew.

The flight from LA to Chicago was smooth and service was very good overall.

Ontario airport boarding was very easy to park and access, is clean and TSA took 10 minutes total. Check-in was a breeze and cruise was very nice.

Left early arrived early..right amount of talking from pilots..of course had to love the biscuit and water!

Boarding gate at LAX was too crowded—two gates next to one another

On time departure and early arrival. Flight attendant very nice.

Everything was delayed and the staff sent me to the wrong gate, causing me to miss one of my flights. I arrived at my destination 6 hours later than I was supposed to.

The SFO Lounge crew were amazing. The bartender Faris was great. Thanks!
