Solved it after all!

Problem:
Kernel 4.2 onwards have a bug in rt2x00 driver that renders monitor mode 
useless because of which I was unable to catch any TCP traffic on Arch 
system(kernel 4.3.3).

Solution:
I have never patched a package/driver before so instead of patching the 
rt2x00 driver I downgraded my Arch kernel to LTS version (4.1.xx)  using 
'# pacman -S linux-lts' and then updated the grub config file. 
Everything works like a charm now!

Thanks Mr. Eli Cooper for pointing this out to me.
