WINGMAKERS' chief Andy Preece admitted that switching Tuesday night's Welsh Cup fourth round tie from the Airfield to Bangor City's Nantporth Stadium was a "tough decision".
But his players made light of the situation by winning 2-0 thanks to a goal in each half from Tom Field.
With more rain forecast, there was no prospect of the tie being staged in Broughton, which would automatically have triggered a switch to City's ground under FAW rules after two postponements.
In a frantic start, Field had a shot well-saved by Lee Idzi, before the ball was delivered back into the box and Chris Budrys thundered a header off the underside of the bar.
The ball was then cleared down to Les Davies, who appeared to be tugged by Ian Kearney just as a clear path to goal began to open up.
Some poor defending from Declan Walker allowed Field to curl a right-footed shot from the edge of the box into the top corner after 26 minutes to give the Wingmakers the lead.
City's Davies had a dangerous low cross deflected wide and Chris Jones hooked a shot over the bar on the half hour, but Airbus continued to dominate and went close to extending their lead before half time through Budrys and Sam Hart.
Preece brought on Steve Jones for the injured Lewis Short at half time, while Citizens' boss Nev Powell introduced Wrexham loanee striker Jay Colbeck, but he was unable to make an impact as a lack-lustre City failed to raise a serious shot on target.
Field had another effort well-saved by keeper Lee Idzi, who was making his final appearance for the hosts.
Colbeck then had a shot easily save by James Coates before Airbus sub Jones sent a shot just wide of goal from a good position following a Field corner.
But, 10 minutes from time, Ryan Wade crossed for Field to slot home his second of the night from 18-yards to seal a highly professional victory and set-up a meeting with either Carmarthen Town or The New Saints in the next round.
