BAA has been allowed to introduce new landing charges adding to the price of flying from Heathrow and Gatwick, the BBC has reported.
The Civil Aviation Authority (CAA) gave the operator the go-ahead to increase landing charges by 23.5 per cent at Heathrow and 21 per cent at Gatwick.
British Airways has criticised the increases and the CAA.
"In practice, they have ignored their own policy and caved in to intense pressure from BAA by setting excessive price increases," said Paul Ellis, airport policy and infrastructure general manager.
Heathrow’s new Terminal 5 is close to completion and will improve transport links for business people into London and its new offices.
Terminal 5’s construction has been difficult and developers have faced regular protests from environmental groups keen to encourage more environmentally friendly forms of travel.
Despite this, the Financial Times has described it as "a triumph intelligent, elegant, airy, functional an antidote to the tired, bodged terminals around it".
