Heathrow hits 6.1m passengers in record March
Heathrow recorded a 2.5% growth in passengers in March compared with the same month last year.
Figures released by the west London airport show 6.1 million travellers used the hub last month.
The growth was driven by business from emerging markets, with China up 12%, the Middle East 9%, Mexico 6% and India 4%. Garuda Indonesia launched the UK's first direct service to Jakarta in March. Carriers have also benefited from larger aircraft such as the Airbus A380.
Heathrow chief executive John Holland-Kaye said: "It's been a record March for Heathrow, and I'm delighted that we've added the UK's first direct connection to Indonesia.
"(With Indonesia) south east Asia's largest economy, Garuda Indonesia's new route will be a significant boon for British SMEs looking for new export opportunities."
Meanwhile, some 3.1 million passengers used Gatwick last month, up 5.8% year-on-year.
Stansted welcomed 1.9 million passengers during March - a 13% rise - while Dubai, Dublin, Amsterdam, Tenerife and Alicante were the most popular international routes from Manchester, which experienced 11% growth, rising to approximately 1.7 million passengers. Luton Airport recorded 1.1 million passengers last month, a 24% increase year-on-year.
