I am in Peru! I flew American Airlines via Miami to get there.
The first leg was done on a Boeing 777 with a 2-5-2 sitting arrangement in economy. I drew the short straw and ended up getting seat 36E, that is right in the middle of the central five seats somewhere at the back. As a result I had to annoy two people every time I wanted to go to the toilet, which on a 9-hour flight I have to d at least twice. On the other hand, I was quite surprised by the leg room which was very good for an economy cabin so all in all the flight was nice. And congratualtions to the pilot who landed us very smoothly in Miami, by far the best landing I've ever had on a 777.
Then I was pleasantly surprised that Miami, as opposed to Houston or Newark, has a real international transfer facility meaning that they take care of your luggage and immigration checks are simplified.
The second leg of the trip was done on a Boeing 757 with the typical 3-3 sitting arrangement. I had an aisle seat and it was a quiet flight, with once again a nice landing. I reckon AA pilots have taken special landing courses recently. That or the automatic landing software on AA aircraft is better than average.
