From an AP story found on MSNBC:
In a first for an online travel company, Travelocity.com has been fined by federal regulators for booking trips between the U.S. and Cuba in violation of a 45-year-old embargo.
Travelocity.com earlier this month paid $182,750 to settle a complaint brought by the U.S. Treasury Department's Office of Foreign Assets Control, which said the company violated the prohibition nearly 1,500 times between January 1998 and April 2004.
Treasury's complaint said Travelocity "provided travel-related services in which Cuba or Cuban nationals had an interest by arranging air travel and hotel reservations to, from, with or within Cuba without an OFAC license."
Elsewhere, OFAC fined one unnamed individual $999.45 and another person $510 for buying Cuban cigars for sale on the Internet.
