Do most airliners have inflight internet?

Wilburn Denice: Actually, most airlines don't have inflight internet.

Shaquita Wernicki: AA is beta-testing inflight internet on some transcon flights. That's all I know of for sure.

Russel Gajate: As far as I know, no airlines have overseas internet, and very few have internet on domestic flights... although some are starting to test it out.
