Mexican Consulate in L.A. takes a wide-ranging role in guiding immigrants to social services. Partnering with U.S. government agencies and nonprofits, the consulate offers aid on parenting, healthcare, labor violations and other issues.
Young adults may travel alone on American Airlines, though they are required to use the unaccompanied minor service if they are younger than 15 years old. A young adult who is at least 15 may be booked as an unaccompanied minor, but you also can book him as a regular passenger. You cannot buy a young adult a ticket without an adult if their travel requires a connection to another airline.
I was told by American Airlines that babies need to be 14 days old to travel. I took my 3rd baby across county at 16 days with no problems...and I had my 2 year old too! That was much more of a challenge! Our pediatrician advised us to wait until 2 weeks after his first round of shots.
