Terms of Service

Toptier Aero is operated by First Principles Foundry LLC ("we", "us", or "our"). It is an independent tool that helps you track award-seat price history, discover sampled award deals, and project airline elite status from activity data you provide or import from your own email account.

Toptier Aero is not affiliated with, endorsed by, or sponsored by United Airlines or any other airline or loyalty program. All airline and program names are the trademarks of their respective owners.

You are responsible for keeping your sign-in credentials confidential and for all activity that happens under your account. You must provide accurate information and use only your own loyalty program data and email account when importing activity.

If you connect a travel email account, you grant Toptier Aero permission to read messages for the limited purpose of finding travel confirmations and loyalty activity belonging to you. You can disconnect your email at any time from the Travel Email page, which stops further scanning.

Award prices, availability, deal scores, status projections, and Global Services likelihood are estimates based on sampled or user-provided data. They are provided for informational purposes only and may be inaccurate, incomplete, or out of date. Toptier Aero makes no guarantee that any deal, price, projection, or tier outcome will be accurate, available, or achievable. Always confirm prices, availability, and status requirements directly with the airline before acting on anything you see here.

Do not misuse the service: no scraping, reselling access, attempting to disrupt the service, or using it to violate any airline's terms or applicable law.

To the maximum extent permitted by law, the service is provided "as is" without warranties of any kind, and First Principles Foundry LLC will not be liable for indirect, incidental, or consequential damages, including missed award bookings, price changes, or status shortfalls, arising from your use of the service.

We may update these terms or discontinue features at any time. You may stop using the service and delete your account data at any time by signing out and contacting us for removal.

Subscription fees. Some features require a paid subscription. Fees are billed in advance on a recurring monthly basis until canceled. All amounts are in U.S. dollars and do not include taxes, which may be added where required.

Billing. Payments are processed by our third-party payment provider. By subscribing, you authorize us to charge the payment method on file each billing cycle. If a payment fails, we may retry the charge and may suspend or downgrade your access until payment is successfully processed.

Cancellation. You may cancel your subscription at any time through the Settings page or by contacting support. Cancellation takes effect at the end of your current billing period, and you will retain access until that date. We do not issue partial refunds for unused portions of a billing period unless required by law.

Refunds. All subscription charges are non-refundable except where required by applicable law or at our sole discretion. Promotional or trial subscriptions convert to paid subscriptions unless canceled before the trial ends.

Price changes. We may change subscription prices or introduce new fees with reasonable notice before the change applies to your next billing cycle. Continued use after the new price takes effect constitutes acceptance of the updated fee.
