Determine the dates on which you're able to fly and the locations to which you're interested in traveling. Select multiple destinations if you wish to travel on a particular day. If you're planning to travel to a particular location to visit a friend, you may have to attempt flying on multiple days before you're able to catch a flight to her city.
Book your flight through your airline contact who provided the buddy pass, or call the reservation system and book your flight. At the time of booking, you'll be notified of any taxes and fees, which you must pay to book your flight. Book the earliest flight of the day, because people sometimes oversleep and miss flights, giving you the best opportunity to get a seat that day.
Dress in the appropriate attire specified on your buddy pass. You're representing the airline and they can decide not to seat you if you're too casually dressed. Pack an extra set of clothing into your carry-on bag, so you'll have clothes in case you get stranded somewhere.
Arrive early at the airport, and check in at the gate. After showing your ID to the agent, you'll receive a standby boarding pass that will get you through security. Passengers using buddy passes receive seats in the order they check in; if you're the first to arrive out of seven passengers traveling on buddy passes and there's one open seat, provided you're polite and willing to wait at the departure gate, you'll get the open seat.
Go through security and wait at the departure gate for your name to be called. Once there's an open seat available, the gate agent will call standby passengers up to the ticketing terminal and change their pass to indicate a seat number. If you're not in the area and they call your name, the next person on the list will get the seat.
