The new flights to Paris and Düsseldorf will commence from 27 April, while the flights to Nantes will start on 4 July and operate throughout the summer months until 12 September.
The Bristol to Paris flights will operate six days a week with two flights per day on Mondays and Fridays. Bristol to Düsseldorf will operate six times a week from Sunday to Friday and will increase the number of BMI routes from Bristol to Germany to four. Bristol to Nantes will operate twice a week – on Tuesdays and Thursdays.
James Durie, executive director of Bristol Chamber of Commerce at Business West, said: "Adding these three new BMI regional routes from Bristol Airport gives business across our region and beyond better connections to two of our most important trade markets.
"In the South West, we have 5,000 companies who are interested in or already exporting to France and Germany, and Bristol Airport also serves businesses from areas beyond such as South Wales."
