PARIS (Reuters) - Iran's Airtour Airlines has signed a memorandum of understanding (MoU) for 45 Airbus AIR.PA A320neo aircraft, Airbus said on Thursday, in a deal unveiled at the Paris Airshow.

Iran has stepped up its orders of planes after international sanctions against Iran were lifted in return for curbs on the country’s nuclear activities.

The Airtour Airlines deal follows a similar one with Iranian airline Zagros that was also announced at the Paris Airshow.
