Virgin Atlantic's first-ever domestic flight service will be known as Little Red.
Sir Richard Branson's airline will start four-times-a-day Heathrow to Manchester flights on March 31. Then on April 5, Virgin will commence a six-times-daily Heathrow to Edinburgh service followed by thrice-daily Heathrow to Aberdeen flights from April 9.
The Manchester frequency offers an extra flight to the three that were originally announced by Virgin.
Virgin is starting domestic services after take-off and landing slots at Heathrow were made available following the takeover of carrier bmi by British Airways' parent company IAG.
Passengers on these new flights will be able to tuck into specially-made "plane" crisps from the Tyrrells company and, on the Scottish services, Irn-Bru.
Sir Richard said: "Virgin Atlantic has been on an incredible journey since we started with a single plane 29 years ago. Little Red represents the next step on that journey as we go head to head with BA to provide domestic flights that deliver our rock-and-roll spirit as well as real value for money."
He added that the European Commission had "recognised that a BA monopoly would be undeniably bad for consumers" and that Virgin's new services "will stop British Airways dominating routes and driving higher prices".
Until March 10, a Virgin return fare between London and Manchester will cost £99.05, with London-Aberdeen £98.30 and London-Edinburgh £98.18. These are start-up fares and it is possible that they might go up later.
BA's return-fare prices during March 2013 for London-Manchester are £106, while London-Aberdeen is £147 and London-Edinburgh £107. BA operates up to 52 daily flights between Heathrow and Aberdeen, Edinburgh and Glasgow.
When flights to London City and Gatwick Airports are taken into account, BA operates up to 94 daily flights between Scotland and London.
