To provide Wi-Fi, planes need to have a satellite antenna, a network modem, and a number of wireless access points around the interior, says Jeff Sare, vice president of in-flight connectivity solutions at Panasonic Avionics Corporation. And all that hardware has to be maintained in addition to installed.

However, YES… large airliners can land successfully in the ocean (that's called a ditching). The primary concern for the passengers is not surviving the ditching (everyone will probably survive)… Rather, the primary concern is getting rescued before they drown or freeze to death.

Jet streams, which are a system of air currents that circle the Earth many miles above the planet's surface, are another reason why aircraft don't fly over the Pacific Ocean. Due to Earth's rotation, these air currents often move from West to East.
