It kind of sounds like you want the button-lock package. See
http://kitchingroup.cheme.cmu.edu/blog/2015/03/18/Clickable-links-for-Twitter-handles-in-Emacs/
for example (and search "clickable text" on my blog for other examples).

Maybe something like:

#+BEGIN_SRC emacs-lisp
(require 'button-lock)
(global-button-lock-mode)

(defvar ticket-regexp "\\([[:alpha:]]\\{2,5\\}-[[:digit:]]+\\)")

(button-lock-set-button 
 ticket-regexp
 (lambda ()
   (interactive)
   (save-excursion
     (goto-char (previous-single-property-change (point) 'button-lock))
     (looking-at ticket-regexp)
     (browse-url (format "http://www.some-ticket-system/%s" (match-string 0)))))
 :face 'org-link)
#+END_SRC

You get no export with this, but it has the functionality you want I
think.
