Yes.... mine is gone. Replaced by an annoying bar/box that says Best vs. Cheapest options. :-( I have no idea how to upload photos, otherwise I'd post a screenshot. I'm also on Chrome with a Windows laptop.

EDIT: Found it. It appears in the middle of the search now, as opposed to the top of the screen where it was before. That's annoying.
EDIT AGAIN: It doesn't show up for all searches. I can't see it when searching for a r/t Seoul to Mauritius. Doesn't seem to work from Seoul. Strange.
EDIT Part III: Looks like it won't come up if you select the "cheapest" box. You have to select "best". Weird.
