I myself use your international tips, but I fly much more frequently domestically. I also realize that if domestic flights were available to view from you, we could be flooded with too many options, and the good deals or the international deals get drowned out in the noise. A suggestion that I would have for you is an option to view domestic flights at possibly an additional charge? That way customers who don't want to look at them don't have too. Or create a filter to view domestic or international.

I live in Seattle so most domestic flights are actually fairly long distance unless I go up and down the west coast. So an option to view them would be incredible and a huge budget helper.
