Hindawi was jailed in 1986 after planting a bomb in his pregnant fiancee’s hand luggage for a flight from London to Tel Aviv. He has lost his application for early release, which was referred back to the parole board in April last year, sources said.
The 57-year-old Jordanian’s release date, without parole, falls in May 2016.
The High Court in London has previously declared the parole decision-making process in his case “unfair and legally flawed”.
Hindawi was jailed after hiding Semtex explosive in the luggage of his pregnant fiancee, Irish woman Anne-Marie Murphy, then 32, without her knowledge.
The explosives were detected and the plot was foiled – avoiding a potential loss of 375 lives.
He became eligible to be considered for parole in 2001.
Successive government ministers rejected his applications for early release, leading to a series of legal battles.
