How to book whole flight for wedding?

Honestly, unless you’re booking a full charter, the only way is buying out all the seats on a commercial flight. People actually do this for weddings. But it requires coordination with the airline’s group booking desk—they sometimes give discounts for bulk reservations.

You’ll need to contact the airline’s charter division. Many airlines allow “exclusive booking” for groups, especially weddings. They charge based on aircraft type and route. Alternatively, private charter companies can arrange an entire plane for you—more flexible but pricier. Start planning months ahead to lock it in.
