嘿，親愛的小伙伴們！在日常出行，有時候難免會遇到需要退票的情況。今天就來和大家好好聊聊退票的相關事宜，讓你在面對退票需求時不再迷茫。

1. 自愿退票：

- 時間條件：通常要在航班起飛前一定時間提出退票申請。具體的時間限制因航空公司、機票價格類型而異。比如有的航空公司規定，全價機票在航班起飛前 24 小時以上申請退票，可享受較為寬松的退票政策；而折扣機票可能要求在起飛前 48 小時、72 小時等更早的時間提出退票申請，否則退票手續費會很高甚至不允許退票。

- 機票狀態：機票必須處于未使用狀態。如果已經辦理了值機手續或者部分使用了機票（例如已經乘坐了其中一段航程），則可能無法辦理自愿退票，或者只能退還部分未使用航段的費用。

- 證件信息：購票時所使用的乘客證件信息需與申請退票時提供的信息一致，以便平臺核實乘客身份。

自愿退票要根據航司退票規則承擔部分或全部手續費。

2. 非自愿退票：

- 航班變動：因航空公司原因導致航班取消、延誤、航線變更等情況，旅客可以申請非自愿退票。例如，航班取消信息需由航空公司官方發布或在線旅游平臺接到航空公司的通知，旅客憑此作為申請非自愿退票的依據。

- 不可抗力因素：如自然災害（地震、洪水、臺風等）、戰爭、恐怖活動、公共衛生事件等不可抗力因素影響出行，導致旅客無法按原計劃乘坐航班，也符合非自愿退票的條件。旅客需要提供相關的證明材料，如新聞報道、政府公告等，以便在線旅游平臺審核。

非自愿退票旅客不用承擔退票費用。

3. 因病退票：

- 醫療證明：旅客本人或其直系親屬突發疾病，無法乘坐航班，需要提供正規醫院出具的醫療診斷證明、病歷、病假條等相關醫療文件。醫療證明上應明確患者的病情、就診時間、預計康復時間等信息，且這些信息要與航班時間相符合，能夠證明疾病確實影響了旅客的出行。

- 關系證明：如果是旅客直系親屬患病，除了患者的醫療證明外，還需提供能證明旅客與患病親屬關系的文件，如戶口本、結婚證、出生證明等。

4. 特殊旅客退票：

- 特殊旅客類型：特殊旅客包括無人陪伴兒童、孕婦、殘疾人等。對于無人陪伴兒童，如果因特殊情況無法按計劃出行，需要提供兒童監護人的書面申請、身份證明等材料；孕婦旅客可能需要提供醫生的診斷證明，說明孕婦的身體狀況不適合乘坐航班；殘疾人旅客則需根據具體情況提供相關的殘疾證明或醫療建議等。

- 提前申請：特殊旅客的退票申請通常需要提前一定時間向在線旅游平臺提出，以便平臺協調相關服務和手續辦理。具體的提前時間要求因在線旅游平臺和航空公司的規定而異。
