Looks like Continental is the latest to inch closer to our dream of WiFi on every flight: the airline just announced that it'll be rolling out Gogo in-flight internet service on 21 Boeing 757-300s in its fleet starting in Q2 2010. The service will cost $4.95 and up based on flight length, and the 757s in question mostly serve domestic routes -- we're hoping Continental takes a cue from American and US Airways and lets passengers check to see if their plane is WiFi-enabled.
