While 2500TT may be Virgin's limit I would suggest it is by no means a generally accepted figure. With your sort of hours I would say you are in a very good position for employment, if not on a widebody (other than the one you are rated on) on smaller jets for sure. 1500TT seems to be a figure quite a few contract jobs require, with 500 on type.
Of course relevant type ratings are valuable and may count for more than pure hours...
DC-10 MyTraveller by any chance?
Best of luck job hunting and check your pm's!
