Good news, frequent (and not so frequent) fliers. In addition to offering free Goggle-sponsored WiFi on its long-range flights this holiday season, Delta has announced plans to expand Gogo internet access to many of its regional jets, beginning in January. The company says that it should have this next wave of upgrades done by the end of 2011. This will definitely come as a relief to those of us who will be enjoying hours-long "regional" flights in the new year, either on Delta planes or those of its regional partners (including Shuttle America, Comair, and Atlantic Southeast). The expansion will apply only to aircraft with a first class cabin -- you know, the spacious compartment you pass through before being herded into the back with the rest of us schlubs.
