Hi shinebrighter,
I met someone who went through some of the A/O training, I believe in October.
She said that JetBlue, after contacting you, gives you 2 weeks, so you can give your current employer your 2week notice. If that is the case, maybe training starts, at the end of February, or early March? I don't know.....
I also read on another site, that JB has more classes in March and April to get ready for the busy summer season????
