I don't know, but I don't think that's relevant.
They probably would not have made reservations

in order not to arouse suspicions.

A Czech source has been keeping tabs on a Czech Intel site in New York. He indicates that Semtex and Anthrax had been given to some of the Al-Qeada in Prague.
The source feels that Atta had gotten the anthrax in the Czech Republic. From who is the big question. Because no one is following up on the anthrax cases in the Czech Republic, a comparison between the anthrax there and the Ames strain can not be made.
The link between the anthrax case in Chile, the Czech Republic and the U.S. has to be investigated to bring more answers to the questions on the Iraq link.
