The quiet overpay

To catch a drop yourself, you’d have to recheck your exact booking for months, and know what it should have cost.

Nobody keeps that up. Euclid does, on every trip you book, until you travel.

How it works

Set it once. Euclid takes it from here.

01

Connect your inbox

Connect your inbox and Euclid finds the flights you’ve booked automatically — no forwarding, no typing. Adding a hotel, or prefer to stay manual? Forward a flight or hotel confirmation to bookings@euclidtravel.ai, or add a trip by hand.

02

We watch the price

Every day we re-check your exact booking against the live market — your flight, cabin, and fare brand, or your hotel, room, and rate. Same booking, apples to apples.

03

You get the savings

When the price drops, we lock in the lower price. For flights we reprice in place — same flight, seat, and confirmation number, and the airline credits you the difference. For refundable hotels we rebook the identical room at the cheaper rate, so you keep the stay and pocket the savings.

Pricing

You only pay when you save.

No subscriptions, no hidden fees. When we win money back, we charge a 20% success fee to your card on file and the rest is yours. If the price never drops, you pay nothing.

  • The savings come straight back to you: an airline credit, or a lower hotel rate.
  • Your flight stays exactly as booked; for hotels we rebook the identical refundable room.
  • Card details are secured by Stripe, and we never store your card number.

FAQ

Questions, answered.

Will you change my flight or hotel?

For flights, no — we reprice the very same flight in place, so you keep the same flight, seat, cabin, and confirmation number, and only the price changes. For a refundable hotel, we rebook the identical room (same hotel, dates, and room type) at the lower rate; you keep the same stay and just pay less.

What if the price never drops?

Then you pay nothing. Our 20% success fee only ever applies when we secure you a credit, and it never exceeds what you saved.

How does Euclid watch my trips?

Connect your inbox (read-only) and we automatically find the flights you’ve booked and start watching them — no forwarding needed. Adding a hotel, or prefer to keep it manual? Forward a flight or hotel confirmation to bookings@euclidtravel.ai, or add a trip yourself. Either way, we check the live price for your exact booking every day.

Which airlines and hotels does this work with?

Major US airlines, plus refundable hotels from the major chains (Marriott, Hilton, IHG, Hyatt, and more). For flights we compare live fares for your exact flight, cabin, and fare brand; for refundable hotels we compare the identical room and rate — so any save is for the exact booking you made.

Is my information safe?

We store only what we need to monitor your booking. Sensitive details like your record locator or hotel confirmation number are encrypted, and we never store your card number — payments run through Stripe. If you connect your inbox, Euclid reads it read-only to find flight confirmations — we parse only those, never store the raw email, and never sell your data. Sign-in is handled by Google.

How do I receive the savings?

For flights, the airline issues the credit directly to you when we reprice. For refundable hotels, we rebook you onto the cheaper identical rate, so you simply pay less. Either way, Euclid charges its 20% success fee to your card on file — nothing more.

You’re a minute away from real savings.

Connect your inbox and Euclid starts watching every trip you have booked. No upfront cost, and you only pay when we save you money.
