# 如何获取改期的报价？
自愿改期的报价包含两部分：**改期规则**和**新航班的差价**。
**1、改期规则**
查询路径： ATRIP -> 订单中心 -> 我的订单 -> 订单详情 -> 订单信息
如果您需要查看航空公司的改期规则，可以单击退改规则中的“查看”按钮，获取相应的票价规则。
**2、差价**
查询路径： ATRIP -> 手工订票
如果您需要计算具体的改期费用，可使用Atlas提供的“手工订票”功能查询新航班的价格，然后计算新旧航班之间的价格差异。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://resources.atriptech.com/bang-zhu-zhong-xin/re-men-fen-lei/shou-hou-piao-wu/gai-qi/ru-he-huo-qu-gai-qi-de-bao-jia.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
