The final total represented a five-fold increase in orders compared to the last show in 2005. The $21.3bn spent two years ago was itself a record for the event at the time.
In total, Airbus was reported to have sealed orders of 297 aircraft during the week, with Boeing claiming 155.
The order book was dominated by operators from the region, with multi-billion dollar deals announced by Emirates, Qatar Airways, Dubai Aerospace Enterprise among many others.
Speaking earlier in the week, Boeing’s president and chief executive Scott Carson, said that Dubai was already on a par with the European shows at Paris and Farnborough in the UK, and would soon overtake them.
“It will not be long before Dubai surpasses them,” he said. “The show has a smaller footprint but we have never seen orders like this.”
