We're kind of like an online ticket seller, but need to talk to US based airlines - how do we get a conversation with them regrading ticketing distribution / partnering...
All of their websites have a "Corporate Contact" on them. Start there and begin identifying who the key players are who you think would see the potential in what you're offering them.
Reach out via sites like LinkedIn and establish a relationship and discuss your product and how it benefits them.
I'm happy to talk more, feel free to book a call here and we can talk details.
