You're right, Recovering-Lurker. This woman tried to report it via the tip line and eventually called Cindy's cell phone.
She stated a gate that doesn't exist at the airport and LE subpoenaed the airline and got the manifest of all children and lap babies. This led to the statement that Caylee was in Atlanta.
The FBI met with this woman, and her son, at a McDonald's and drew a sketch of the woman traveling with "Caylee"...a blond woman in her thirties. I believe the woman's husband had little to add, although he was traveling with the family.
I think we were warned about reacting too much to this particular claim because the tipster was or is a guest poster here in the past.
All I know, for sure, is that LE ruled this sighting out months ago so I am not sure why she has revealed herself on tv. I also believe Cindy has moved on from her belief of this sighting since she believes Caylee is in Gainesville. Or in a mall in Orlando. Cindy's most recent claims, if you notice, are all in Florida.
