此方法可为指定行程提供高级别的票务组。这些对象包含一组具有所选服务舱位的航段，这些航段可使用同一张机票预订，还包含机票的整体票价和供应情况信息。请注意：
- 所有 ticketing_.*_id（属于 SegmentKey 的一部分）都将引用 Google 公共交通票务扩展程序中提供的相应 ID。
- 标识符必须保持稳定，并且对这些标识符的任何更改都必须向后兼容，如 GTFS 集成要求中所述。

// Request sent to partners. message GetTripOptionsRequest { // All segments together should form a single trip for which a ticket can be // booked. repeated ext.travel.transport.partner.SegmentKey segment_keys = 1; }

API 实现备注：
为了实现与潜在更改的向前兼容性，如果在段键中遇到其他参数，请务必在响应中返回这些参数。否则，请忽略这些参数，并将请求视为没有这些参数，直到您实现对这些参数的特定支持。
