Many travel startups often realise they need to switch to or add some kind of B2B model pretty quickly - so it is fairly unusual to see one go the other way.
30K is one such company, having launched in 2014 as a way for online travel agencies and metasearch engines to display air miles for every flight result it returns.
The company (TLabs here) has an API for travel companies to integrate the original product but has since launched a consumer-facing tool.
The idea is that consumers can download a browser plug-in which then automatically calculates the number of frequent flyer miles that are available on a ticket when the user searches on an online travel agency website.
Any connections with the OTA are unofficial.
30K users can then see their award miles, status segments and points for each flight.
Before making the booking the user can ask for a summary of their potential earnings.
Websites participating in the Chrome browser tool include Expedia, Travelocity, Hotwire, Wotif, Orbitz and Cheaptickets.
The company says it is adding other OTAs and browsers shortly.
The company raised $650,000 from Tripsta in 2015.
Here is a clip of how the browser plug-in works:
