Thistle returned to the top of the Irn-Bru First Division in superb fashion, as Chris Erskine bagged a brace, Aaron Muirhead netted from the spot and Lawless, Sean Welsh, Kris Doolan and Ross Forbes added their names to the scoresheet.
Airdrie were no match for the red-hot Jags as they were swept aside at Firhill, with Jackie McNamara's side turning on the style to hit the goal trail.
Lawless said: "We started really well and got a couple of quick goals. That gave us a bit of confidence to get on the ball and attack them. Coming back to Firhill helped us because it is a bigger park than we have played at recently and we had more space to play in.
"I think it could have been even more, to be honest. The place is buzzing after a result like that, so hopefully we can take it into the Falkirk game this week.
"In the games we have had this year, there have been a couple of times where we could have run riot but it never quite happened.
"Everything clicked for us on Saturday and we knew that when it did click that we could do that to somebody. It was just unfortunate for Airdrie that it was them."
The points were secured for Thistle after just 10 minutes as Erskine curled home his first of the afternoon and Muirhead converted from the spot after the Jags' talismanic forward was fouled in the area.
Lawless made it 3-0 on the half-hour mark before Welsh and Erskine netted in quick succession before the break to cap off a sublime 45 minutes and the former Motherwell youngster hailed his strike partner after the duo terrorised the Diamonds defence.
Lawless said: "Squiddy is unplayable at times. I don't know how you defend against him to be fair. He is so tricky and he has got that clumsy look about him that helps him a lot. He knows it himself and he says it.
"He has got a technique and a run that works out perfectly for him. He got two goals on Saturday so that is him one ahead of me for the season, but I will need to try and claw that back against Falkirk.
"As long as we are winning, that is the most important thing. We will get chances and we want to score as many as we can personally but, if the team is winning, the goal tally is secondary We have got goals in us, so as long as we can keep showing that as a team we will be happy."
With title rivals Dunfermline and Morton cancelling each other out at East End Park, Thistle will head into the second quarter of the campaign top of the First Division.
They travel to Falkirk this weekend and Lawless knows they have plenty of hard work ahead in the championship battle.
He said: "We could have asked for nine wins from nine, but we have to be delighted with the start. To be top of the league after the first quarter is great, and what we wanted at the start of the season.
"The challenge for us now is to stay there. There will be a lot of teams that will see us as a scalp and who will want to be beat us. As long as we can keep the good run going then I am sure we will be there or thereabouts come the end of the season."
