London's Heathrow Airport has unveiled a £10 billion ($13. 5 billion) investment plan to expand capacity, aiming to handle an extra 10 million passengers per year by 2031.

For the first time in a decade, Heathrow will also create new terminal space for new lounges, shops and restaurants within existing terminals.

Britain's Heathrow Airport said it could serve an additional 10 million passengers per year by 2031 by making changes to existing terminals if it can increase fees, as it presented its plans for the next five-year period to the regulator on Friday.
