A fifth of U.S. baby boomers say one of their biggest regrets is not traveling enough, according to a new survey.

Yet more than half say they cannot afford to travel during retirement, and 38 percent say they have never had a passport, according to the British Airways Holidays survey of 2,000 U.S. baby boomers aged 55 and older.

The survey also found that more than a fifth of baby boomers say work commitments have kept them from traveling overseas, with 17 percent of men saying working too much is one of their biggest regrets. Only 8 percent of women said they regret working too much.
