“(unknown current hero — generic travel-marketplace pattern)”
The hero is a search form with minimal explanatory copy. A visitor comparing Kayak vs. Google Flights vs. Skyscanner cannot tell from the first viewport what Kayak does differently. Meta-search is the differentiator, but the word never appears.
“Compare every airline and OTA in one search. We find deals they don't show each other.”
Names the mechanic (meta-search across competitors), implies exclusivity ("deals they don't show each other"), and differentiates from single-source search engines. One line, one reason to stay.
