I will arrive at 14.30 on Monday. Can you come to the airport? Will I be able to rent the car from Monday?

My (probably pitiful)  attempt:

Ben Pazartesi de 14.30 a varacaðým. Havalimanýya sen gelebiliyor musun? Pazartesiden araba kiralayabilecek miyim?

Thanks for all corrections. 

Pazartesi günü saat 14:30´ta varacaðým. Havalimanýna gelebilecek misin ? Pazartesi gününden itibaren arabayý kiralayabilir miyim ?

 Thanks Melike1. Why do I always forget to put gün after the day of the week?????

And I learnt a new word today - itibaren. Thank you

Pazartesi günü 14:30 da geleceðim.

Havaalanýna gelebilir misin?

Pazartesinden itibaren arabayý kiralayabilecek miyim?

 I am getting a little annoyed by your translations after mine, Gülbil. Because without saying what was wrong with my translation you put your version while i know mine was also (almost) mistakeless.

If you write your translation in a different way thats fine with me but can you than also correct mine ? At least say what was wrong or at least say that my translation is also understandable. Thank you...

so who cares about your ego try to come a little later and write after gulbil then for example, i am saving ALL attempts from here and when i have TIME (i mean, really TIME, not just 5 minutes or smth), i look at them all and search (if there are any) for differences and ask from natives, if i doubt about smth - so gulbil keep adding yours, too

Who is talking about my ego and also ´sen ne karýþýyorsun ?´ i wasnt talking too you.

Also I said ÝT ÝS FÝNE THAT GÜLBÝL ÝS ALSO PUTTÝG HÝS VERSÝON. Thats much better. Off course his translation can be better than mine and more correct after all he is the native. I just dont like it is being showed as my version is incorrect or even worse not understandable. The most important thing is too be understandable for the receiver of the message. People can trust my translations are understandable.

oh, i´m sorry, didn´t realize this site here was called www.lets_sing_anthems_to_melike1.com, i thought i registered to www.turkishclass.com for learning turkish only...my mistake, should read those terms of registration and using the site more carefully. but i will correct my mistake and redo registration by deleting me from here. i am not much of a singer anyway, and for LEARNIG anything here this site seems a bit too hostile for me exercises were good, but forum part is sometimes pretty much like a WW 3.

Ne saçmalýyorsun Allah aþkýna ? Ne yapacaksan yap, beni ilgilendirmez. (just some stuff for your learning )

...and Xena the warrior queen has spoken maybe you should sometimes just bite your tongue and control your ego - gives you a little time to think before placing your hands on a keyboard that way you would at least avoid pointless show-off comments you constantly add in forums if you think you are better than anyone else here - in knowing turkish, for example (and yes i know you LEARNED it, too, just like everybody else, you´re not a native speaker - and that makes it more pointless to show off in front of other learners) - then by all means be better, nobody has ever questioned that but why you feel like you HAVE TO prove yourself to others all the time? let others to learn, too? can´t you just be a FRIEND? why you need to try to be a royal leader? learners don´t need to be ruled, they need to be thought.
