I am probably just being dense, but where can one add the email address of a second passenger to a reservation? My Father booked tickets for he and my Mother, his email address is on the reservation and he received the pre-order email, but obviously as DELTA did not have my Mother's email address, she did not receive the email.
My Mother called in and she said the rep was able to take her selection over the phone, but I figured that DELTA must have a way to add a second email address. I scoured their reservation but I could not find a place to enter my Mom's email address.
Regardless on the outbound segment they reported back that they both received the choice, so calling does work, but Mom wanted to make her selection over the web, like my Father did.
