Jackson Family Members -- Find Your Own Way Home

TMZ has learned ... several members from the Jackson family are going to have to find their own way home from Wales -- because the company that was supposed to provide them with a flight back has pulled their tickets ... because of a HUGE outstanding bill.

As TMZ first reported, Entertainment Travel Company claims that Global Live (the company behind the Michael Jackson tribute concert last week) owes $200,000 for plane tickets the company booked for the Jackson family, Christina Aguilera, her crew, Jamie Foxx, Heavy D, roughly 15 Global Live employees and others.

Now a rep for Entertainment Travel Company tells us they had no choice but to yank the tickets which were earmarked for two members of the band 3T (TJ and Taryll) and two of their children ... because of the unpaid tab.

The company rep says they held out for as long as they could and the next step is to contact a lawyer.
