Flybe today launched six new routes from London City airport.
The regional airline now flies from LCY to Aberdeen, Belfast, Edinburgh, Exeter, Dublin and Inverness.
The carrier said it expects to carry around 500,000 passengers annually to/from the airport.
And CEO Saad Hammad said the airline is targeting business travellers as part of its London expansion plans.
He said: "Our new London City routes provide direct links for customers in the regions to the heart of London's financial district.
"From today, purple Flybe aircraft will be a regular feature in the skies above the City of London as we begin daily services with six aircraft into/from London City airport.
"This can only benefit our brand profile and reach over the longer term as knowledge of Flybe's role in connecting the UK regions and Ireland with London becomes more widespread."
Earlier this month, Flybe announced a partnership with Avios to replace its existing Rewards4All frequent flyer programme (see news, October 10).
