 but how can I translate havası batsın

çok teşekkür  ederim 

Hava (means air) is a slang usage here:

hava atmak = show off, make a great show (of himself or something on/about himself) etc

so "hava" refers to the "show off" of somebody

so

havası batsın = down with his "show off", let his show off be downed, I hope his show off goes away (disappear) soon, etc.
