I am on the SAS flight from Seattle to Copenhagen, somewhere north of Iceland. I am using the onboard wireless internet service. Ironically the airplane is a Airbus 340, but the wireless service is offered by Boeing. $30 for the whole flight or $0.25/minute with a minimum of $10.
The service is not too bad; high latency, but sufficiently downstream bandwidth to get email in. Not much bandwidth for sending.
Latency: 750 millisecond to amazon.com
Bandwidth: 287 kbps downlink, 27 kbps upstream
Using a desktop feedreader would probably be effective, but the bloglines experience surprisingly does not suffer too much from the high latency. BTW the plane also has nice 110V sockets.
I am on my way to the UK to speak about Amazon.com Web Services at a UK government sponsored event.
