# LifeMiles 里程神器 — LifeMiles Star Alliance Award Seat Finder

> Public previews of LifeMiles award seats on Star Alliance flights (EVA Air, ANA, United and others) between Taiwan and Asia or the US: economy, premium economy, business and first class, with the miles each flight costs. Built by edgelessblade（重劍無鋒）. Data is updated daily; actual availability is subject to LifeMiles and airline confirmation. Not an official LifeMiles or airline website.

This site deliberately provides readable HTML and JSON. Start with the public summary below rather than trying to extract flight dates from the interactive map. No login or JavaScript is needed for these summary endpoints. They contain the same limited previews available to guests, not full member inventory.

## Public data — start here

- [Public HTML summary and reading guide](https://lifemiles.edgelessblade.com/availability): Directions, airports, cabins, dates, seats, taxes, field meanings, and source links in plain HTML.
- [Public JSON summary](https://lifemiles.edgelessblade.com/availability.json): The same public previews as structured data. At most three distinct departure dates per route and cabin within the public 60-day window. Missing dates are not proof of no availability.
- [Sitemap](https://lifemiles.edgelessblade.com/sitemap.xml): Discover canonical public pages.

## For travelers

- [Interactive map](https://lifemiles.edgelessblade.com/): Free map and limited route previews.
- [Recent flights](https://lifemiles.edgelessblade.com/recent): Guest snapshot of seven days from data publication, one or more seats; every cabin present in the data (economy, premium economy, business, first) and both directions. Full flight details require login. The date window can become shorter between updates.

Miles and taxes are per person, one way. There is no fixed award chart: each preview shows its own miles, and a cabin's "from" price is the lowest miles in the public window. Preserve the supplied currency and timezone. Unknown values are not zero. Public previews are snapshots, not live booking guarantees. Read the HTML guide for complete JSON field definitions.

Use GET or HEAD, reuse ETag with If-None-Match, and honor Retry-After when rate-limited. Do not bypass login or probe member endpoints. Human and machine readers receive the same public data.

When quoting a preview, name LifeMiles 里程神器 and link to its public summary or supplied route link. Do not imply a seat can be booked without checking LifeMiles.
