So I'm currently on holidays somewhere, and it's one hour ahead of where i live. Since i went on the areoplane and landed to a new country where the time is an hour ahead, this also means i technically landed into the future, right?

No.

Why? Can you support your argument? :)

But I'm technically one hour ahead of everyone back home, so I'm living one hour into the future.
 
No. Just like you won't be ahead of time if you just set your clock to time+1h without moving from home.

But if you change the time on your phone that won't actually change the time, whereas I'm currently an hour ahead of everyone back home.

Call them on the phone and see if you have to wait an hour for a reply.

They probably wouldn't even respond, but that's not the point.

Yes, it IS the point.

i'm pretty sure the reason they wouldn't respond is not only due to time difference.
 
It's the same time, but we need to write the time fully to see that.

Suppose Dorothy and her dog Toto are in Denver Colorado and it is 9AM.
We write it as 09:00 MST, where the 'MST' denotes Mountain Standard Time.
Or more fully as 09:00:00-07:00 in standardized ISO 8601 notation, which means we have subtracted 7 hours from Universal Coordinated Time (UTC).

Now she and her dog are magically transported to Kansas City (instantaneously), where it is 10AM, or rather 10:00 CST, with 'CST' for Central Standard Time.
Again more fully 10:00:00-06:00.
Both are also written as 16:00:00Z, which is the time that a clock at the zero meridian (Greenwich, England) shows.

So even though the local clock shows a different time than Dorothy's watch, which really represents the altitude of the sun, it really is the same (UTC) time.
It's similar to how degrees Fahrenheit are converted to degrees Celsius. It's a different number but the same temperature.
