Well I took my RadarBox to Australia, Singapore and Hong Kong last year with no problems at any airport ,think i might be a bit more nervous about it now though.
I have stayed in airport hotels at Sydney, Hong Kong , Singapore ,Brussels, Toronto and Vienna and have asked for rooms overlooking Runways ,Aprons etc. After all isnt that why we want to stay in airport hotels to watch the planes.
Staff have always been more than willing to help, and i just hope we will be able to continue to do our hobby in what should be the comfort and safety of a hotel room.
