KUALA LUMPUR, Nov 2 (Bernama) -- London Heathrow ranked last and New York’s JFK first among eight international business hubs in eSIM provider Holafly’s Airport WiFi Stress Index, which compares airport Wi-Fi conditions for business travellers.

At JFK, Wi-Fi speeds reach 151.6 megabits per second (Mbps), enough to download a large presentation in about 30 seconds, while at Heathrow speeds drop to 12 Mbps, meaning the same file takes more than five minutes, or up to 13 minutes during the morning rush, Holafly said in a statement.

“Every minute an employee spends waiting for a file to load is time the company is paying for,” said Holafly Head of Sales for B2B Direct Sales, Davide Ilardi.

Some airports also limit free Wi-Fi sessions. In Frankfurt, sessions expire after 30 minutes and in Dubai after 60 minutes, with each additional hour costing about US$5.40. (US$1 = RM4.05)
