Frequently Asked Questions

What is a routing rules calculator?

A routing rules calculator analyzes airline fare routing rules to generate all valid flight routings. It considers stopover limits, transfer restrictions, IATA area constraints, and maximum permitted mileage to show you which routings comply with fare rules. Routing Ruler automates this complex analysis.

How do stopover and transfer limits work?

Routing Ruler lets you specify the maximum number of stopovers and transfers for your routing, either globally or by IATA area. You can set different limits for different regions (e.g., max 1 stopover in Europe, 2 in North America). The tool generates all valid routings that comply with your specified limits.

How does carrier filtering work?

Routing Ruler shows you which carriers are allowed for each segment based on fare rules. You can filter results by carrier or alliance (Star Alliance, Oneworld, SkyTeam) to see only routings using specific airlines. The tool displays which alliance each carrier belongs to, making it easy to understand your routing options.
