The non-profit air show is still trying to come to an agreement with the cities of Peoria and East Peoria.
The cities want a total of $42,000 from the air show in advance to pay for things like police overtime and clean-up.
But the air show says it didn't budget for that.
And now the two sides are trying to come up with a plan to save the show, which could mean postponing it for months.
The air show says the cities didn't ask for the money until March.
So we asked the city of Peoria if it should have told the air show about the $42,000 fee sooner.
"We've had a good dialogue with the promoters of the air show," said Peoria City Councilman Ryan Spain. "All the issues have been understood for quite a while and we want the air show to happen."
"We just need to all sit down together and figure out who is going to be responsible for what," said Air Show Director Brett Krause. "As air show organizers, what are we going to take care of on the riverfront. What are we going to ask the city to take care of."
There's no new date set for the Air Show, but organizers are considering sometime in August.
