Other international carriers such as EK, QR, etc. are hiring pilots. While its probably not the 100% of choice, they can retire, get their pensions and still work for another carrier (if that other carrier doesn't have a mandatory age-requirement for retiring). While its not post-retirement, I do know of one person who's brother was on the right side of an AA B777 for a number of years and "bailed ship" to QR to pilot their B777's.
