Hello

You haven't requested proofreading but I am still going to talk.
1) Kui tormame, siis tean,
tean = I know (tead = you know)
2) On kergem hingata kui ootavad meid kauged teed
kergem = easier, lighter (raskem = harder)
3) Kuid tasakaalu leida saad kui kodus keegi ootab ees
ootab (ees) = is waiting (otsib = is looking for)
4) Ja nii me teeme
Üle taeva tiire
With this part you have become quite creative. It sounds very good.
5) Me koduks saamas
On lennujaamad
The verb 'olema' + ma-infinitive+s (inessive ending) is the closest thing Estonian has for progressive aspect. [The same with 'kõlamas', 'to resound' is probs the closest translation. Noun 'kõla' is the tonal character of sound, btw, 'sonance' or sth like that. If sound had taste, it would be called 'kõla' XD.]
So, Airports are about to become [or are becoming] our home.
(on saanud = have become)
6) Me võõraks jääme
Kui meil on kiire
'Jääma' is like German 'bleiben',
This here is either a) we will become strangers or b) we will stay strangers. Probably a).
(I'm sure you considered translating it as 'if', so let's just skip it.)
I think you got a bit creative in your translation (the original is quite bland or plain).
When we are busy/ in a hurry. (We don't really have a good equivalent for busy :( )
But yours works great.

Anyway, all things considered: Great job!! *applause*
Point 3 makes me think that you might have learnt Estonian...
