Flyers can now access free Wi-Fi via T-Mobile at Los Angeles International (LAX) and Los Angeles/Ontario International Airport (ONT). The “curb to nose” coverage area in LAX spans more than 3.8 million square feet making it one of the largest Wi-Fi hotspots in the world. Unfortunately, you’ll have to pay for access. T-Mobile charges $9.99 for a 24-hour block of service, or $6 for one hour.
