Bristol achieved a record month in August by handling more than 700,000 passengers.
The busiest month in the airport’s history eclipsed the previous record of 691,000 set in the same month in 2008.
Passenger numbers were up by 4.11% over August last year, completing a record-breaking summer following new totals for the months of June and July,
Total annual passenger numbers for the UK’s fifth largest airport outside London are now forecast to pass the six million mark for the first time in five years.
The airport is targeting 10 million annual passengers in future years, up from 5.9 million in 2012.
New or additional services to Corisca, Frankfurt and Dalaman all proved popular this summer.
Business travel is also expected to continue the upward trend seen during the first half of the year following the end of the summer holiday season.
Airport chief executive Robert Sinclair said: “When you consider that approximately the same number of passengers used Bristol airport this August as passed through the old terminal in an entire year just over two decades ago, it puts the scale of this milestone in perspective and shows how far we have come.
“Our record-breaking summer is a positive sign that consumer confidence is returning, which is good news for the southwest economy as a whole.
“More and more people across the region are choosing Bristol when travelling for leisure or business, demonstrating the important role regional airports can play in meeting local demand for air travel.
“The next major landmark in our sights is 7 million passengers per annum, which we hope to achieve in the next two to three years as we work towards our goal of becoming a world-leading regional airport handling 10 million passengers each year.”
