People packed the lakefront. The lineup included the Blue Angels, the Navy Leap Frogs and the Firebirds.
Megan McDonald with the Mayor's Office of Special Events said the crowds were a little light on Saturday, but the weather improved Sunday and the size of the crowds grew.
"It's beautiful - I'm impressed, I love it," said Ramona Hornaday. "It's my first time and I'm enjoying myself."
"To see what can be done in the air, it's like unbelievable what these guys are doing," said Naren Makwana.
The Chicago Air and Water Show is in its 52nd year.
"Chicago is one of our favorite jumps we get to come to every year," said Sgt. Daniel Cook of the Golden Knights. "The skyline is great, the view is awesome, the people are outstanding. We thoroughly enjoy coming here every year."
Chicago's Air and Water Show is said to be the largest free show of its kind in the United States.
A 3-year-old suburban boy had a wish come true at the Air and Water Show on Sunday.
Niles resident Devin Karvaras got to meet members of the Golden Knights parachute team.
The Knights also presented him with their 'baton.'
The Make A Wish Foundation arranged for the meeting. Devin is undergoing treatment for leukemia.
He was joined Sunday by his father and brother.
