Ebola in US: What route flight did the case take from Monrovia?

Ebola in US: What route flight did the case take from Monrovia? HT: Crof.

Via The New York Times: Ebola Is Diagnosed in Texas, First Case Found in the U.S. Excerpt:

Dr. Frieden declined to disclose flight information or to say whether the patient is an American citizen. He said the man was not a health worker, and officials had no idea how he had become infected.

The man left Monrovia's Roberts International Airport on September 19, a Friday, and arrived in Dallas on Saturday. On the assumption that it was a regularly scheduled flight, then the departures schedule for Friday, October 3, should indicate the most likely flight: One codeshared as United Airlines 9974, Air Canada 6374, and Lufthansa 5549.

The flight would have left at 8:40 p.m. for Brussels, where the case would have arrived about 5:15 a.m. local time. He would then have transferred to at least one other flight to Dallas. 

I may be wildly wrong, but any competent travel agent could figure out the man's complete itinerary in a few minutes. So it seems pointless for Dr. Frieden to "decline to disclose" that information. The CDC certainly has it, whether or not it thinks tracing the passengers is worthwhile, and the Belgian health authorities presumably have it as well.
