Revenue increased 8% to £622 million and EBITDA was up 7.2% to £342 million.
The company, which also owns the Heathrow Express rail link, urged the Government to make a quick decision on building a new runway.
Heathrow and Gatwick are battling for the right to add a new runway and increase capacity.
A decision is due after next month’s general election.
Heathrow chief executive John Holland-Kaye said: "Heathrow is a fantastic airport and a great front door for Britain.
"We’re a business that’s delivering an unrivalled passenger experience in western Europe, we’ve got over 30 airlines knocking on our door waiting to serve the UK’s hub, our world-class shareholders are lined up to privately fund expansion and with an additional runway we will create 40,000 new skilled and well-paid jobs for the local community.
"We are ready to deliver the only runway that can connect all of Britain to global growth. All we need is a quick decision, so let’s get on with it."
