Why FareSift
The cheapest flight and the cheapest trip are rarely the same thing.
FareSift gives every itinerary a job, a complete price, and an honest risk label.
02
The price you can actually use
Bags, seats, payment costs, transfers, hotels, and expected disruption exposure belong in the answer.
03
Every tradeoff explained
Separate-ticket risk, fare rules, eligibility, and support limitations are shown before you commit.
A strategy, not a wall of listings
One search. Several intelligent ways to win.
We organize the answer around what matters: lowest cash, best value, lowest risk, best with bags, and the fare you should avoid.
