However, Atta was indisputably caught on airport cameras in Portland, Maine, boarding a flight to Boston to connect with one of the hijacked planes.

He has also been identified by key witnesses in the investigation, including flight school operators in Florida, a honky-tonk bar operator in Florida, where Atta and another hijacker spent their last night,...

Did he fly from Florida, up to Portland and then to Boston, all on 9/11?

Or has this reporter made a mistake?

I heard that there were some Al Qaeda people in the Florida bar the night before, but I never heard that Atta was one of them.

I believe he did make a mistake. If I recall correctly, the bar in Florida where they got drunk ("Islam, Shmislam", apparently) was a couple of nights prior.
