自行轉機 無托運行李是否需出入境 (求解惑

超齡兒童
大家好
這次要從杜布羅夫尼克回台灣
好不容易找到預算內的機票,卻只能自行轉機
爬文後發現有些自行轉機必須於轉機點 出境 再入境
由於skyscanner搭配的機票,轉機時間只有3小時
(依上次在杜哈轉機的經驗,感覺一般轉機1.5-2小時綽綽有餘)
但這次第一次自行轉機,希望能多了解狀況
希望有經驗的前輩能幫忙解惑,感謝!

我只有手提行李,無託運
2個轉機點&時間如下

1.挪威航空
杜布羅夫尼克- 赫爾辛基萬達
轉機時間:2小時50分

2. 卡達航空
赫爾辛基萬達- 哈德瑪國際機場
轉機時間:2小時56分

3. 卡達
哈德瑪- 香港

由於芬蘭跟卡達都可以免簽(轉機)
所以簽證也不用擔心
但如果以上兩國需出境再入境轉機的話
免不了要轉 出入境大廳、重新排隊入境手續
怕機場太大或隊伍太長來不及?

不知道以上轉機時間夠不夠呢?
先感謝各位經驗分享及幫忙!!

in hkg international to international you may run through security check around gates/terminals to airlines. there has no need to immigration service. i'm not sure other 2 airports does the same. you may assume required but 3 hrs transit should be enough.

Thanks a million!
I don't worry about the transfer in HK too much as you said
Everything is clear and friendly to tourists
And hopefully... another two are as easy as in HK
