Aircell already managed to coerce American, Delta, Virgin America and Air Canada into installing its Gogo in-flight internet equipment into at least a few of their airplanes, and now United Airlines can proudly say that it's no longer looking in from the outside. Starting this year, a baker's dozen of the company's Boeing 757s -- which will fly between John F. Kennedy International Airport in New York and California's Los Angeles International Airport and San Francisco International Airport -- will be armed and ready with WiFi for the people. Pricing will remain set at $12.95 for the entire flight, and service is expected to roll out during the second half of this year.Filed u
