My (LoganFlyer's) guide to maximizing your bump chances on Delta:

(The concise version:

1. Use the App to see if more people are looking for seats than there are seats available. As part of the Customer Commitment, gate agents, phone res agents, and tickets agents must tell you if a flight is overbooked if you ask. (They don't need to say by how many seats.)
2. Do everything you can to get on the volunteer list through OLCI or a kiosk at the airport, since some GAs use that list.
3. Talk to the GA as soon as the gate opens up--don't wait for them to make an announcement.
4. Don't be afraid to negotiate with the GA.)
