And a summary of the first few paragraphs, in line with FT's policy on external links:
Passengers who bought cheap British Airways flights say they are angry after their tickets were cancelled because the prices were wrong. The airline said it had sent incorrect fares to a number of travel agents for flights to Tel Aviv and Dubai. Ash Dubbay, from London, says he had booked a return flight to Tel Aviv for £195 but now has to pay about £1,000. BA has apologised and offered full refunds and a £100 voucher. The company refused to say how many were affected.
