SABRE Create PNR接口问题：生成PNR与所选航班不符

问题背景 #

集成SABRE Create PNR Rest API生产环境冒烟测试时，创建的PNR在SABRE黑屏系统中显示为最高价航班，但我方门户实际选择的是最低价航班。已在请求体中添加Fare Basis Code，问题仍未解决。

问题分析与参数补充方案 #

核心问题点 #

1. 舱位代码不匹配：请求中AirBook.FlightSegment.ResBookDesigCode使用的是Y（全价经济舱），但指定的Fare Basis Code QANJOP对应Q舱（低价舱位），系统会优先按预订的舱位定价，导致最高价。
2. 未锁定低价规则：仅添加Fare Basis Code不足以强制系统使用低价，需补充票价锁定参数。
3. 起降时间异常：DepartureDateTime与ArrivalDateTime完全相同，可能导致系统解析异常，影响定价逻辑。

需添加/修改的参数 #

• 修改舱位代码：将两个FlightSegment的ResBookDesigCode从Y改为Q，匹配Fare Basis Code对应的低价舱位。
• 添加票价锁定参数：在AirPrice.PriceRequestInformation.OptionalQualifiers.PricingQualifiers下添加FareQualifiers节点，明确锁定票价规则：

  "FareQualifiers": {
      "FareBasis": {
          "Code": "QANJOP",
          "ResBookDesigCode": "Q"
      },
      "PricingMethod": "N"
  }
  

  其中PricingMethod: "N"表示按指定票价计算，避免系统重新定价选择高价。
• 修正起降时间：调整FlightSegment的DepartureDateTime为实际起飞时间，比如去程改为2024-03-14T10:55:00，保持ArrivalDateTime为2024-03-14T12:55:00，返程同理修正时间差。
• （可选）添加报价ID锁定：如果之前通过SABRE询价接口获取了PriceQuoteID，可在AirPrice.PriceRequestInformation下添加PriceQuoteInfo节点，确保使用已确认的低价报价：

  "PriceQuoteInfo": {
      "PriceQuoteID": "your-price-quote-id"
  }
