To speak with a live representative at DDelta Airlines:

1. Call Customer Service: Dial Delta Airlines customer service number at 1-800-123 -6645 / +1-802-705-4010 (United States). For international callers or specific inquiries, visit delta's official website to find the appropriate customer service number based on your location.

2. Don't Select Options: When prompted by the automated system, refrain from selecting any options. Some systems might transfer you to a live representative if you don't select any options.

3. Say "Agent": During the automated prompts, say "agent," "representative," or "operator." This might route the call to a live person.

4. Remain Silent or Press Zero: If none of the above options work, staying silent or pressing zero repeatedly might transfer the call to a live agent.

5. Use Online Chat or Social Media: delta might offer online chat support on their website or assist through social media channels like Twitter or Facebook.
