To me £195 for a return flight to Tel Aviv sounds cheapish but not 'manifestly incorrect', if it had been a return fare to Dubai in First Class for £195 then perhaps it would be manifestly incorrect, unless they advertised it as a special offer. I once saw a land only package for Israel including tours and multiple nights accommodation advertised for something like £40 - with something like that I wouldn't dare to book it and then buy flights separately on the presumption that I would be able to go without paying any extra.
BBC News said: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.

A BA spokeswoman said the contract with customers was not legally binding if the price was "manifestly incorrect".
The firm said the incorrect tickets were "hundreds and hundreds of pounds" cheaper than they should have been and BA was not in a position to honour them, although it refused to say how many such tickets had been sold.
BA said: "Errors like this are exceptionally rare, and if they do occur, under contract law, there is no binding contract between the parties.
"We have apologised to customers and offered a gesture of goodwill."
