代理买票，只能找代理

这个可能要加钱
去哪儿最大的问题就是各种代理为了给自己省钱不惜乱下单

就，没办法。你只能找去哪儿。老实讲，第一步就是，买机票不要找代理。。。

在哪儿买也别在去哪儿网买机票，看到过听到过的各种纠纷太多了。
就代理而言飞猪携程算靠谱。

问代理

最好抓紧问航空公司。
前两天也是去哪儿买的国内机票，遇到要改签，找去哪儿网，半天没有反映，问所有人工都是会自己没有权限，会通知经办人什么时候前回复的，请耐心等待，但实际上就没有回复。自己拿着机票找航空公司改，航空公司说预留的电话又不是我在去哪儿留的，可能是被去哪儿的代理商留成他们的，而且我一起买的4个人，还被拆成两个单子，办什么都不方便

可以看以下信息：

里面说了If you have already made your Booking and need to change the passenger type please contact us here. 所以就是要改passenger type得联系他们。
另外有https://help.ryanair.com/hc/en-gb/articles/12889654202641-How-do-I-add-a-minor-16-years-to-a-Booking
里面说了
How do I add a minor (< 16 years) to a Booking?
Minors (2-15 years) cannot be added to an existing adult’s Booking (as they are not allowed to travel alone), however you can create a new adult Booking for them and link it to your original Booking so you can travel together. The passenger type will be updated for each minor during the linking process to either a child (2-11years) or teen (12-15 years).
Important Info
To link the Bookings, go to the original adult Booking and select “Add minors” from the left-hand menu
Select, or retrieve, the new adult Booking you created, enter the date of birth for each minor, and then both Bookings will be linked with the passenger types updated.
You should check-in online for both Bookings, otherwise you will be charged at the airport. Minors will be issued temporary boarding passes during online check-in.
If purchasing a seat for a child, we recommend selecting a seat as close as possible to an adult in the original Booking.'
When you arrive at the airport, go to the check-in desk where all minors will be issued valid boarding passes.
For children with no seats assigned, staff at the check-in desk will assign seats next to an adult. If that's no possible, cabin crew will help seat you together.
大概就是说如果你已经买了票想加一个儿童的话，只能先去买一个成人票，然后把这个票关联到你的成人票下面，这个时候就可以更改乘客类型。所以你应该先试试联系瑞安修改乘客类型，不行的话单独再买一张成人票，然后关联并且修改乘客类型。
