JetBlue has recently announced a beta service they are offering on select planes. This service “BetaBlue” is wireless im and email from 10,000 feet. Basically you can email and use IM (live and yahoo) from the comfort of your seat and any wireless smartphone or laptop.
At this time they don’t offer “surfing” but being this is beta I guess it could be coming next.
I look forward to trying this FREE service out when I take a trip to Florida next year.
