Jordan Air Force chief Major General Mansour al-Jobour told reporters the air raids launched since Thursday had destroyed 20 percent of ISIL capabilities.
"On the first day of the campaign to avenge our airman Maaz al-Kassasbeh, 19 targets were destroyed, including training camps and equipment," he said.
Jordan has vowed to crush ISIL after the terrorists burned alive Kassasbeh, who was captured in December when his F-16 warplane crashed in Syria.
Eighteen more targets including ammunition and fuel depots and logistics centres were hit on Friday.
On Saturday, 19 ISIL targets were destroyed, including barracks and residential centres.
"So far, the campaign has destroyed 20 percent of the fighting capabilities of Daesh," he said.
Foreign Minister Nasser Judeh told Fox News this week the air force had targeted ISIS in both Syria and Iraq where the terrorists have proclaimed an Islamic "caliphate" in areas it controls.
"We are determined to wipe out this terrorist gang," Jobour said during Sunday's press briefing.
The air force will step up strikes against ISIL over the next few days, he added.
Interior Minister Hussein Majali said in remarks published on Saturday that Kassasbeh's gruesome murder by ISIL was a "turning point" in the kingdom's fight against extremism.
Jordanian air strikes are "the beginning of an ongoing process to eliminate" ISIL, Majali was quoted as saying by government newspaper Al-Rai.
Jordan is part of the US-led coalition of Arab and Western countries that has been carrying out air strikes against ISIL since September.
Jobour said Jordanian warplanes have flown 946 sorties out of a total of 1,500 by the coalition since the campaign began.
"More than 7,000 Daesh criminals have been killed since Jordan began participating in the air campaign," he added.
The country's air strikes have contributed to crippling ISIL oil revenues, Jobour said.
ISIL has targeted oil and gas facilities in Iraq and Syria as it seeks to finance its campaign and seize more territory for its "caliphate".
