I urgently need a flight from Santiago de Chile to Houston Texas,
leaving 30, 31 March or 1 April  returning 5days or one week later for
as little money as possible. Please find a ticket

Dear Lulu55

I checked out mobissimo.com for the dates of Mar 30 (leave Santiago) and
 Apr 6th (return from Houston) and it is coming up with an airfare of
 $905.65. The flight is with Aeromexico and goes via Mexico City.  
I checked another date (1st apr to 8th april) which was a bit more expensive.

I have pasted the results of the mobissimo search below.
Hope this helps!

Check out the last minute offers at despegar where it says "Pasajes en oferta."
Right now there are no direct flights to Houston; however it would be
a good idea to see if there is something available tomorrow.
