A decision by Qantas to end its international flights out of Adelaide is a "sick joke" on South Australians, independent Senator Nick Xenophon says.
Senator Xenophon says the decision would force those people travelling on Qantas international flights to travel first to another state.
"Qantas's senior management assured me in September last year that the Adelaide-Singapore service was safe - that assurance has been broken," he said.
"Why is it that other countries' airlines fly in and out of Adelaide over 80 times a week - yet our national carrier is now abandoning South Australia on international routes?"
Qantas currently operates Adelaide to Singapore services three times a week but announced on Monday that they would stop at the end of March.
