Vim airline displaying issue

Question

I was setting up vim-airline and for what ever reason I can't get it to display like powerline. Any help would be appreciated. .vimrc

set noswapfile
execute pathogen#infect()
syntax on
set laststatus=2 
set lazyredraw
let g:airline_theme             = 'powerlineish'
let g:airline_enable_branch     = 1
let g:airline_enable_syntastic  = 1
let g:airline_left_sep          = '⮀'
let g:airline_left_alt_sep      = '⮁'
let g:airline_right_sep         = '⮂'
let g:airline_right_alt_sep     = '⮃'
let g:airline_branch_prefix     = '⭠'
let g:airline_readonly_symbol   = '⭤'
let g:airline_linecolumn_prefix = '⭡'
highlight constant ctermfg=yellow

Here is what it looks like.
