If you're refering to CTOTs then are you sure you're not getting confused with the Slots-for-Airmiles Hotline used by some charter operators?
Good grief who said that?!
Seriously though, I saw something that may be relevant whilst on a visit to VIR Ops. They have access to a CFMU web page that gives very up to the minute CTOTs - they often get them before we do on our DSM. I believe you have to be a registered customer and they may even have to pay for it.
