Generally, Surface Mail shipping is slower than Air Mail shipping. This is especially true if you reside out side North America where Surface Mail is shipped via ship. If you live in Australia, for example, it may take up to 8 weeks for your shipment to be received via Surface Mail. If, however, you reside in the USA, shipping will take between 2 and 3 weeks. Air Mail to the USA takes between 7 and 12 days, and to Europe, between 7 and 14 days. Note that these are estimates. There are always going to be shipments that take longer, or even shorter. The record so far is 3 days shipping to the UK, and the worst rate was 9 weeks via Air Mail, also to the UK. Once shipped, we have no control over how long shipping will take.
I really don’t want to be mean, but do you know what Google is? It’s not like the answer stays within your question. Do you know the difference between air and surface? Well, that makes the difference between mailing through air and surface. But if you still have questions or need a more detailed answer, then just research it on the internet. Here is a reference link for you https://sourcingbro.com/. I hope that this will be helpful. Again, sorry if I was mean. I didn’t mean to upset you, but I hate when people don’t bother finding answers to basic questions.
All parcels and letters delivered using AirMail reach the addressee quickly and without delay. However, as for Surface Mail shipping, in this case, there are delays, and a person will have to wait much longer for his letter. And if you need to urgently send some kind of letter or parcel, it’s better to use AirMail if it’s still for a while, then Surface Mail shipping services will be much cheaper. By the way, do not forget to read articles about sending because I recently received a fine because I sent too much tobacco and whiskey to my brother via mail.
Airmail tends to be more expensive because of the costs of transporting parcels by plane. On the other hand, ground mail tends to be a cheaper alternative. Specific prices vary widely depending on the destination and package size. Just recently sent a package to another country to a friend of mine. I even had to ask for pallet delivery.
