Welcome to FlyerTalk.
You'll notice FlyerTalk is sufficiently large our threads are generally organized by categories, within those by travel or service supplier and further by topic. For some answers, such as destinations and cabin class, you might wish to visit the Delta and United fora, and of course their respective websites (for route maps and schedules).
This is not a Technical Support issue, and it inquires about companion travel on two competing U S airlines. Though FlyerTalk is generally oriented toward flying, status and benefits, earning and spending miles and points - leading to a lack of information about such issues as employee buddy passes, companion travel, etc. we will move this query to the Information Desk forum for possible answers.
