Wouldn't recommend absconding for the following reasons:
1. You knew the conditions when you signed the dotted line. Aviation is a very small world and someone will get to know about it. Unless you had execptional circumstances, I wouldn't hire you after absconding.
2. Some of the airlines will try to go after you/your career. Not sure how succesful they are.
3. You would of course lose all your End of Service Benefits.
My advice, stick it out. I think most Middle Eastern Airlines bond you for 3 years. not a long time really. The grass may not be that much greener on the other side after all. Our airline (EK) had guys leaving for BA and coming back!!
Good luck with your decision.
