Caslon is still in development and open only to a small group of testers. Join the waitlist
Add protection to your trip in a minute. If the delay happens, you get paid. No claim forms, no waiting on hold.
Caslon isn't open yet. Join the waitlist and we'll let you know when it is.
Check any US flight from July and August 2026 with real data. See if it would have paid, and what it would have cost.
Your flight number, or your ZIP code for rain. Choose how much you want paid if it goes wrong.
One price, shown up front. Pay by card, Apple Pay or Google Pay.
Official flight and weather data decides. If it happened, we send your payout to PayPal, Venmo or Zelle.
Protection is only worth something if the money is there when you need it. Here's how Caslon makes sure it is.
Your price goes into the payout pool.
Caslon's own money is in it too, and covers payouts first.
Official flight and weather records, checked against the rule you bought.
In dollars, to your PayPal, Venmo or Zelle.
From the payout pool, which holds money set aside only for payouts. Everyone's prices go in, and so does Caslon's own money. If payouts run higher than expected, Caslon's money takes the hit first. We only sell protection the pool can back, and when it's full we stop selling until there's room. In the rare case one event costs more than the pool holds, everyone affected gets the same share of their payout.
The data does, using the rule you saw before you paid, like “lands 2 or more hours late.” We go by official flight arrival records and weather station readings. There's no claim to file and nobody judging your case.
In dollars. Once the data shows it happened, our team checks the result and sends your payout to PayPal, Venmo or Zelle. You don't need anything new, just the account you already use.
It's kept safe and ready. Money that isn't needed yet can only go into U.S. Treasury bills, which are short-term loans to the U.S. government. A share always stays in cash, ready for payouts.
Caslon isn't available yet and isn't selling anything. We're building parametric cover: it pays a fixed amount when official data shows something happened (like your flight reaching the gate two hours late), not based on a claim about your losses. Before we offer it to the public we'll make sure it's offered in line with the law, which may mean working with a licensed partner.
Flight results come from flight-tracking data (FlightAware, cross-checked with a second source) and, in the demo, from the U.S. Department of Transportation's on-time records. Rain comes from official airport weather stations. The rules are fixed before you buy, and nobody at Caslon decides your case by hand unless the data disagrees.
Payouts come from a pool of money set aside only for payouts. Caslon puts its own money in first, so it takes the first loss. We limit how much cover we sell for any one airport, area and day, and we pause sales before big storms. If one event ever cost more than the pool holds, everyone affected would get the same share of their payout.
In dollars, to PayPal, Venmo or Zelle. Our team checks each payout and sends it.
We're testing with a small group now. Join the waitlist and we'll email you when we open.
Please share it! Add a note when you join the waitlist — we read every one.
Whether you're paid is decided by official flight and weather records, not by a claims adjuster. There is nothing to file.
