# Stopover Rules per Loyalty Program Reference data for which programs allow stopovers on award redemptions, how many, where, for how long, and at what cost.

Some programs let you stop for a week. Some let you stop for 365 days. Some don't allow stopovers at all. The headline value: a free stopover lets you visit two destinations on a single award. Iceland on the way to Europe. Tokyo on the way to Bangkok. Singapore on the way to Sydney. ## When to Use This Skill - User wants to plan a multi-city trip and asks "what's the best program for stopovers?" - User asks about a specific program's stopover rule (e.g. "does Aeroplan allow stopovers?") - Building a trip itinerary that could benefit from a free second destination - Comparing programs for award redemption when stopover flexibility matters - Ide...
