Big difference in crew bases for AA these days and JFK is very competitive market so AA has great facilities such as catering there.
Thanks for the post. And to the other people who have replied.
About the JFK-SCL flight... I did think about this as JFK-SCL is operated by Lan Chile with a nice new 787 whereas the MIA-SCL I have booked is operated by AA in an ancient 767. However, Lan Chile has unrealistic ideas about children in business class which would cost me about $8,000 to pander to, so that was an instant no-go.
