JetBlue Will Offer Limited e-mail on Flights

JetBlue Airways Corp. will start offering limited e-mail and instant messaging services for free on one of its planes next week as airlines renew efforts to offer in-flight Internet access. General Web surfing and e-mail attachments won't be permitted because of bandwidth constraints, and services on laptops and hand-helds with WI-Fi wireless access will be limited to e-mail and messaging from Yahoo Inc. Passengers can check other personal and work e-mail but only on two Blackberry models that have Wi-Fi wireless capabilities, under a deal with BlackBerry maker Research In Motion Ltd.
