Building Part 1: Forwarding Emails

I had a project idea a month or so ago when I was part of a group planning some holidays. We were booking flights and accomodations, but the confirmation emails only went to the account of the person that actually made the booking. So I thought, wouldn’t it be nice if we could all get those emails? Well, some services do allow submitting multiple contact email addresses or adding “guests” to a booking, but not all of them do.
