THERE should be no “price limit” on the search for MH370 because of the importance of solving the mystery.

Qatar Airways CEO Akbar Al Baker made the remarks in response to the Federal Government’s decision to provide no further funds to the mission in the southern Indian Ocean.

Australian taxpayers have already shelled out $90 million towards the complex operation, and Malaysia and China have also contributed.

In 18 months of searching, vessels using hi-tech equipment have been unable to find any trace of the Boeing 777 although debris has washed ashore on Reunion Island and Mozambique.

Mr Al Baker said it remained of critical importance for countries “in this region” to find out what happened to the Malaysia Airlines flight that disappeared almost without trace over two years ago.

“For me as the CEO of an airline, it’s very concerning that the international community for monetary purposes are going to abandon the search for this aeroplane.

“I don’t think there is any amount that is too much to find why this tragedy happened where over 200 people lost their lives.”

He said finding answers was of particular relevance to countries “that you reach by being overseas for a long time”.

“IATA (the International Air Transport Association) has not done enough to raise the concerns of the airline community,” said Mr Al Baker, who is in Australia to launch direct flights between Adelaide and Doha.

“It is very critical for all in the industry, all the countries in the world to try to find the wreckage of this plane, to find out exactly what happened.

“In my opinion, it’s something unprecedented in our aviation history that an aircraft just disappears without trace and nobody’s able to find it, and nobody knows why.”

Jeanette Maguire whose sister Cathy and brother-in-law Bob Lawton were on board MH370 said she understood that the search could not go on indefinitely.

“I have very mixed emotions. This is my sister, her husband and their friends (fellow Australians Rodney and Mary Burrows),” said Ms Maguire.

“I don’t want the search to stop. We need to find our loved ones and know where their resting place is.

“But I am also a realist, and you have to ask where the money is going to come from to be able to continue the search. Many millions have been spent so far.”

Officials from Malaysia, China and Australia will meet when the priority search zone is fully scoured, but they have previously announced the operation won’t be continued without fresh evidence.
