For complex issues like booking multi-city trips or using SkyMiles awards, calling **1-855-907-2853** remains more efficient than chat, as agents can access broader tools over the phone.
United Airlines actively monitors Twitter (@United) 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)-907-2853** provides faster resolution than waiting for social media responses.
