Manx2.com is to operate flights between the Isle of Man and Cardiff for TT 2011.
The route to the Welsh capital will run through practice week until the end of race week (May 27 to June 12).
The TT service has been arranged after Manx2 received requests from race fans in Wales during the past year.
Manx2 chairman Noel Hayes said: 'We had many enquiries about a direct flight from Cardiff to the Isle of Man, so have added the route for the TT festival.
'This year marks 100 years of the mountain course, and we are giving more fans the opportunity to experience the great event.'
Mr Hayes says there is a possibility an Isle of Man-Cardiff service could be added to the regular timetable.
