More than 250,000 people have gathered at Seaburn and Roker seafront to enjoy the Sunderland International Airshow.
In its 26th year, the airshow has seen the Red Arrows, wing walkers and an aerobatic team take to the skies during the three-day event.
Sunderland City Council said on Saturday alone, a quarter of a million people enjoyed the displays.
Deputy leader Harry Truman said the event had been "just brilliant" and he was "very happy" to see so many people.
Mr Truman said: "As I've said before and I'll keep repeating it, it's the people that make this airshow.
"I think we will top one million visitors this weekend, definitely."
An opening ceremony took place on Friday evening with a concert and fireworks, although low cloud forced the cancellation of a flying display.
The BBC World War One at Home tour gives people the chance to explore their relatives' links to the war.
BBC Newcastle is the official radio station for the show and is broadcasting from the seafront across the weekend.
