Had a reply back with:
Hello Lee,
We would not show under ABTA as we are a holiday comparison site where travel agencies advertise their offers, the names of agencies who advertise on our platform can be found next to each offer, once you know the name you can type this into ABTA to find out their ABTA details.
Also just to add all agencies who advertise with us offer full financial protection.
Thanks,
I've just done a search on that website and it cam up with travelsoon as an offer. I've checked this site on ATOL and its coming back registered.
Find the prices on that site then go to the site offering them.
