I fly all the time for business. It's always in my carryon so it doesn't take a trip without me. There are no airlines I know of that allow you to use it in flight.

I alwaysfly with my GPS in my carry on and never have a problem. We usually fly American, and their policy is that you cannot use it during flight. This might vary between the different airlines. Worry you won't be able to make MOGA, but like you said, a free trip to San Diego ain't too shabby.

There are a ton of caches near the convention center/marina and I wonʼt have much time. Anybody have a recommendation for either a super good cache or some quick and easy ones? Difficulty factor: HUGE convention-lots of muggles. 2. I havenʼt flown for a long time. Whatʼs the scoop on GPS receivers on planes? I donʼt intend to use it on the plane-any problem with just carrying it on with me? 3. Is there some new rule about batteries or lithium batteries specifically? Not OK to carry them on or not OK to put in checked luggage? I seem to remember reading something about this a while back. Thanks and everyone have a great time at MOGA-wish I could join you all. Hope the MOGA magic charm works on the weather! Susan Get the MapQuest Toolbar, Maps, Traffic, Directions & More!
