Regional airline Flybe is set to add 12 flights a week to its London City to Belfast City airport service from 7 May.
The increased frequency includes new morning, early evening and weekend flights, offering business travellers up to six services a day and 35 per week.
Flybe says the route is one of its most popular, especially with corporate travellers journeying between the two hubs.
From Monday to Friday, the earliest new flight departs Belfast at 0835 and returns from London City at 1040, with a flight time of one hour and 40 minutes. Then, every day except Saturday, services will leave Belfast at 1535 and return at 1740. New Saturday flights depart Belfast at 0955 and return at 1200.
