> Etickets (and any voucher for residual credit) can only be used by named passenger.
Yeah, I guess so.
> AA does the same way.(at keast for last 10 years)
For AA (my main carrier) I always had plenty of opportunities to use the credits. I remember a cancellation would yield credit in the ticket number, name-locked to original passenger. But then I thought when that credit was used only in part, AA would send a paper voucher which was usable for anyone (no longer name-locked). No? If I could do this for Delta, that would work GREAT for me -- hoping there is a way...
