If the DL employee overseas has a computer connection that employee can login in and make the listing.
All you have to do is check-in at the airport a few hours before your flight go to the gate and wait for a standby seat.
I don’t have a HELP number but you could call Delta Airlines reservations at 1-800-221-1212 and perhaps have your
call forwarded to a department that can help you out.
Reservations maybe able to list you if you have the employee’s ID information (you will have to get that from the
employee).
