Re: Are flashlights allowed on airplanes?texts
I flew with a whole bunch of flashlights and spare batteries between US and Germany (Surefire A2, L2, L4, U2, some Inovas and Fenix's as gifts, SC1 and SC2 carriers, BatteryStation's Pelican case for 123's, an Otter box full of Alkies and Lithiums AAs and AAAs, red and green laserpointer in Pelican case).
In the US, not many raised eyebrow, except that they had to scan my bag a few times. It was packed pretty tight, with some gadgets (laptop, MP3, digicam etc.). Was handsearched one time ("What's in this box?" "Digicam" "In this?" "Spare batteries" "And in this?" "Umm, more spare batteries" [TSA guys sighs, shakes head] "OK, move along").
In Germany, was handsearched pretty extensively. Similar dialogue as above, but the guys actually opened the cases. Some snickering remarks ("Hey, take a look, this guy's prepared"). The Surefire SC's were not closely inspected, maybe because they are clear. The Pelican cases were more suspicious.
Overall, not much problems. Nowadays the amount of spares I carried probably would be raise more suspicion. I will pack more sparingly next time.
Just don't take anything weapon-like, like large Mags and similars ('club-like objects' in the TSA texts), or heavily crenelated bezels.
