Flights under $100 to anywhere
Every fare below is a real observation under $100 from a US city, ranked by how far it sits below what that trip usually costs — because a $79 fare that is normally $210 is the find; a $79 fare that is always $79 is just a bus with wings.
Yes, with the honest caveat stated everywhere on FareFloor: prices are recent observations refreshed several times daily, not live quotes; every fare links to a live availability check. Every row above was observed in our scans within the last two days, and clicking it opens the route page where the fare is re-checked live before you book.
Why show the 'usually' price next to a $60 fare?
Because cheap and a deal are different things. Some routes are always $60 — nothing wrong with them, but nothing special either. The fares worth acting on are the ones sitting far below their own usual price, and that is how this list ranks: deepest cut first, not lowest sticker first.
I don't care where — I just want to go somewhere for under $100. How?
That is FareFloor's entire premise. Fix your origin, stay flexible on destination and dates, and the board ranks everything by how far below usual it sits. This page filters to sub-$100 fares from US cities (2026-10-13); your city's full board has every price point.
