The new PNR deal between the EU and the US has been criticised by the Association of Corporate Travel Executives (ACTE).
Susan Gurley, the Association's executive director, said the agreement offered one "small improvement" at the expense of "three significant disadvantages."
She said the drawbacks were the amount of time passenger information can be retained by the US authorities, the number of agencies which have access to this data and the rights of passengers to see this data.
The deal, which comes into force on August 1, stipulates what data European airlines must supply to the US on passengers they are flying to America.
Ms Gurley said: "Someone needs to speak out for the rights of our European members and all international travellers.
"This Association has been a strong advocate for preserving these fundamental rights for US travelers, and the same protection should extend to travellers from outside the US."
"It's ACTE's responsibility to be cognizant of both the security needs of the US government and rights to privacy of European travellers.
"The reduction in the number of required data fields now sought by the Department of Homeland Security from European travellers clearly indicates that over 40 percent of previously collected information was unnecessary."
Under the new PNR agreement, European airlines must supply the US with 19 items of information about each passenger, a reduction in the previous 34.
But the US authorities can keep this information for up to 15 years instead of three as previously.
The data will also be available to numerous US agencies which can make limitless use of it and there is no designated venue for Europeans to view the data.
BA consortium sets deadline on Iberia bid
BA and its fellow consortium members have set a time limit on their bid for Spanish national carrier Iberia.
They want a reply to their request to see Iberia's book to conduct due diligence by the end of July.
The consortium also includes US private equity firm TPG and three Spanish partners, private equity group Vista Capital, which belongs to Santander, Spain's largest bank, Ibersuizas and Quercus.
The original request for due diligence came from TPG in March when it launched its own bid of 3.4m for the carrier.
BA already has a 10% stake in Iberia and an option on a further 26.5% and both airlines are members of the oneworld alliance.
The Iberia board is due to meet today (July 12).
