Power in flight for the well-prepared. Some airlines now advertise that they have computer power outlets in first or business class. Don't plan to plug your standard power cord in, though. Verify charges for telephone time before you call. Before you sit down in your hotel to work, dial an outside operator and verify that the local telephone dial-up number for your computer system is actually local to the hotel.
Some cities have per-minute toll charges for calls outside a surprisingly small radius.
