JetBlue Airways doesn't have a specific "Melbourne Office" for general public visits like a retail store they operate through airports and online, with their main focus being U.S. domestic and some international routes, so you'll find their presence at airports like Melbourne Orlando International Airport (MLB) for flights, or need to contact their customer service via jetblue.com/contact-us or by phone for specific needs, as they are primarily a U.S.-based carrier.
