Delta Airlines actively monitors Twitter (@Delta) and Facebook. Tweet your issue or send a Facebook message for relatively quick responses. This works well for general inquiries, complaint escalation, or tracking down lost items.
However, for immediate needs like same-day flight changes, calling **+1-(855)-321-3345** provides faster resolution than waiting for social media responses.
