Don´t worry you will be fine.  I will be waiting at the airport for you.

I am only learning and although I think this would be understood it is only basic so wait for corrections

Don´t worry you will be fine

Merak etme, sen iyi olacaksın

I will be waiting for you at the airport.

Havalimanıya ben seni beklemeyi olacağım.

OR

Havalimanıya ben seni bekleceğim.

Hopefully I will learn where I am wrong when it is corrected.

Thanks Tinababy x

Havalimanıya? - to there?

shouldn´t that be Havalimanı(+n?+)da? - there?

 or am i missing some point there...

Always get "at/to/in" mixed up!!!! I thought da/de meant "in"

But I stand corrected. Is that the only correction?

 Since the intent here is to be reassuring.  It is better to use aorist (general) tense instead of future because it conveys that you OF COURSE will be waiting.

"Havalimaninda ben seni beklerim"

Merak etme, herşey iyi olacak (If I translate word by word, I should have said ¨merak etme, iyi olacaksın¨. But it doesn´t make any sense to us. We don´t use it like that. I translated it the way we use) Ben seni/Seni havaalanında bekliyor olacağım.
