Cynthia Montgomery testified that she arranged a $15,000 flight to Sao Paulo at the request of Marc Schaffel, who is named by prosecutors as one of the unindicted co-conspirators in the Jackson case.
Prosecutors contend Jackson's associates planned to keep the family in Brazil indefinitely in the aftermath of the Feb. 6, 2003, airing of the TV documentary "Living With Michael Jackson." Jackson appeared with his accuser in the documentary and said he allowed children to sleep in his bed, although he asserted it was non-sexual.
Montgomery was granted immunity because the FBI is investigating her in relation to the secret videotaping of Jackson and former attorney Mark Geragos during a charter jet flight she booked. The charter flight brought Jackson from Las Vegas to Santa Barbara where he surrendered to authorities on child molestation charges.
Montgomery said she booked the accuser's family on a flight scheduled to depart for Brazil on March 1, 2003.
She said Schaffel asked her to book a one-way trip but she had to arrange a round-trip flight because Americans are not allowed to enter Brazil with one-way tickets. She said she arbitrarily chose a return date.
The family never made the flight and prosecutors did not discuss the reason why in court.
The accuser's mother has testified that she orchestrated her family's escape from Jackson's associates by claiming her children had to visit their grandparents before they could leave for Brazil. The mother has said the family left Jackson's Neverland estate for the last time on March 12, 2003.
On cross-examination, defense attorney Thomas Mesereau Jr. immediately noted that Montgomery was testifying under immunity granted by Superior Court Judge Rodney S. Melville.
The travel agent's testimony came a day after Mesereau announced that one member of the defense team, Brian Oxman, was no longer on the case. No explanation was given.
Oxman, a long-time Jackson family lawyer, is the fourth attorney to part ways with Jackson since the singer was charged in 2003. Jacksonwith Mesereau and Susan Yu a year ago. In October, Jackson announced that longtime attorney Steve Cochran was taking a temporary leave.
"The attorney scuffle is a sign, yet another sign, that Jackson has terrible difficulty handling the people around him," says.
Also Monday, Melville ruled the pop star's ex-wife, Debbie Rowe, can testify as a prosecution witness, but her testimony may be restricted, especially certain areas the defense claims would "open a can of worms" that could greatly prolong the trial, reports CBS News Correspondent Vince Gonzales.
"There's no telling what she could blurt out in front of the jury," says CBS News Consultant J. Randy Taraborrelli, a Jackson biographer.
Rowe is locked in a legal fight with Jackson over custody of their two children, Paris and Prince Michael.
Prosecutors claim she took part in the so-called rebuttal video that aired on television, after she was told she would have access to the children.
Jackson, 46, is accused of molesting a 13-year-old boy in February or March 2003, giving the boy alcohol and conspiring to hold the boy's family captive to get them to rebut the documentary
