Ask HN: How to monetize a travel site?

I've built up a travel deals website over the past 7 months in Australia (https://www.beatthatflight.com.au). As it's grown, I've grown several hundred followers on FB, an email subscriber list of hundreds too. I know, that's still small change, but it's been fun to see it grow. I currently 'monetize' by using a white label payout program. People search for flights on my site, buy a ticket, and boom, I get a tiny commission. However, it's not much. I'm debating how to grow this further. Any suggestions? I don't want to alienate my audience, but I would like to start earning more than a few dollars a month. I love finding deals and still get a thrill when I find an error fare, so I do well on that side, but in terms of growing/monetizing I'm starting to run out of ideas. Possible directions: - start charging for immediate deals, and keep my free subscriber list getting once a week summaries of deals found. - Chuck advertising on the page. Not really sure how effective that'd be and whether it'd turn people off. - I've considered making a bunch of infographics and sharing them around some sites to get traffic, but I feel it's the conversion I'm failing a bit on at present. Eg 5000 flight searches might translate into 3 tickets bought. I don't know if that's normal but it 'feels' low? - Hand search for people. Like flightfox did, but ... it's not terribly scalable. Anyway, I'd love ideas. Tech summary: I built it on wordpress, mailchimp newsletter, FB/twitter/instagram posts, google analytics, plugged into a whitelabel system, and monitor google news and other deals emails for bargains. Plus 'artful' searching - sometimes it's possible to feel a deal out, if that makes sense.
