A deal with Qatar Airways for Airbus aircraft, scrapped by the carrier in a day of drama at the Dubai Air Show earlier on Tuesday, is back on track, an Airbus spokesman said.

Qatar Airways slammed the brakes on an expected $6.5 billion deal with Airbus at the last minute, as the airline's head signed a deal with Boeing and told its European rival to go back to basics.

This time it will happen, the spokesman said.
