I take mine when I fly- and I point out as soon as the airport people touch it that it is a $16,000 piece of medical equipment. Then they ask me what it is, and I tell them it is basically a compressor and no problem (and then they unzip and bomb sniff it and give it the once over <img src="i/expressions/face-icon-small-wink.gif" border="0">). And for some reason, either my Pulmozyme or my Xopenex always sets off something at the Orlando airport on our way home (the foil packages new and unopened when I leave, and are open when I come back).
I also usually take my meds in a "7 day planner case", and copies of the prescription on the bottle (I roll the bottle as the scanner goes across-lol). Has anyone ever had a problem with doing this, or know anyone who has? So far, it's been okay, but I haven't flown in over a year...
