Not sure if I read you correctly,

Do you mean taking the same flight path without having to open dialog with the Flight Master? I am pretty sure (from reading most of the posts here) that this is not possible.

The following addons will allow you to pick the same destination if you have the dialog open on each character. You still open the destination window on all chars, but it saves you the hassle of having to click the destination on all your chars.

ZQB

Zanthor's Quest Broadcaster (Beta)

Multiboxer

[Addon] Multiboxer V2


Hope this helps.
