Ryanair based a second aircraft at the site in 2023, adding Carcassonne, Edinburgh and Venice to its list of destinations.
TUI added a second plane over the summer, with an extra 60,000 seats available.
And low-cost airline Jet2 is launching 20 new routes from the Dorset site from February, including the Canary Islands, Spain, Majorca, Turkey and Portugal.
More than 840,000 passengers used Bournemouth Airport between April and October - an increase of nearly 103,000 compared to the same period in 2023.
Predicting the boost in January, bosses previously said they were investing more than £5m in new facilities, equipment and staff to cater for the rising numbers.
The plans include expanding the airport's terminal buildings and car park.
Managing director Steve Gill dubbed the airport "an alternative to the busy London hubs".
"More and more people are recognising the convenience and ease of travelling from their local airport, and with the exciting developments under way, we’re looking forward to an even wider range of destinations in the year ahead,” he added.
