疫情期间各航司的回国票退政策有什么变化吗?

比如UA和东航的。

UA里程好像都是可以退的,就是要交手续费?

但大部分现金机票订了只能转信用点,一年内用完?
In all other cases, a refund may be requested for any fare that allows refunds. Depending on the rules of the fare purchased, a cancellation fee may apply. Most fares are nonrefundable, and are not eligible for voluntary refunds. However, the value of your ticket may be eligible to be applied toward the price of a new ticket for a fee. Tickets are valid one year from the date of ticket issuance, except for tickets purchased between May 1, 2019 and March 31, 2020, which are valid for 24 months.

美国的航空公司现在一般改票免费。除非你再不回美国了,否则改票也行

我记得是本土航班改票免费啊。另外和回不回美国有啥关系?是要给家人订单程回国的票。
