Thanks for the above replies. I was able to book three tickets for my family in J thru AA miles. So, that is done.
Now I am looking to purchase my ticket in J and have a few questions. On google flights, I was able to find a fare for 50% less than what AA is charging but through LATAM. Two flights have AA flight numbers and two flights have LAN numbers.
How will this work with EQM/EQD earnings?
