All hail the laggard! With pretty much every other US-based legacy carrier already on board, we were beginning to wonder if American Airlines even got the memo that in-flight WiFi was in serious demand. At long last, the company has made clear that it plans to equip more than 300 MD-80 and Boeing 737-800 aircraft used primarily in the United States with high-speed WiFi capability (over the next two years). If you’ll recall, American announced early on that it was game for trialing the tech, but until today, it had yet to make a commitment large enough to make you consider signing up for its credit card and bankrolling those frequent flyer miles. We’re expecting more details to emerge soon, but feel free to start pestering its agents with the whos, whats, wheres and whens.
