How long does it take to travel via airplane to Rio brazil?

from lax

From NYto Rio,its about 8 to 9 hours.
So add 5 hours from LAX to JFK
Equals 14 to 15 hours.

from miami it's about 6 to 7 hours

I know for sure that to Sao Paulo from LAX it's 12 hours, but to Rio I guess it's 10-12 hours.Just ask them...

From NY it's a 9-10hr flight... lay over in Sau Paulo then you have to take into account the 1-2hour time change (depending on if you do it before or after our October 21st time change. Right now it would be a 1 hr change). If you leave at 11pm... when you get there, it will FEEL like 2pm because of the jet lag your body is feeling.
