關於空郵信件/包裹的運送方法

1. 如在外地以空郵方式寄件到本港,
是否只會用寄出國的國營航空公司運送,
而不會使用私營的(例如本港的航空公司)?

2. 如果寄出國與香港之間沒有直航班機,
就算是使用空郵服務,會否很久到寄到本港?
(我的例子是東歐國家--愛沙尼亞,會多久才到?)

謝謝解答.

Usually airmail would be around 4-6days... But of course that also depence the postal system of the 2 countries you are sending post to and from...
Usually these letters and cargo will just fly on pax or even cargo flights to their destinations...
If there is no direct flight services like Estonia, its most likely that it will go via Moscow on SU flights since this is the most direct way...
I think they will just fly those post to the nearest country that got direct flight then redirect those post to those countries from there...
